Commercial Construction Costs in San Diego, CA (2026): What Owners and Developers Pay by Building Type
Commercial Construction Costs in San Diego, CA (2026): What Owners and Developers Pay by Building Type
San Diego sits inside the most expensive regulatory stack in U.S. commercial construction — California prevailing wage, Title 24 Part 6, CBC 2022 with municipal amendments, CASp accessibility, Coastal Commission overlay, CARB equipment rules — and on top of that, runs the densest biotech construction cluster in North America. The combined effect pushes commercial pricing 18 to 28 percent above national, and biotech lab costs into a category of their own.
What does commercial construction actually cost in San Diego in 2026? Class A office runs $545 to $745 per SF, Class B/C office $345 to $475, retail $245 to $365, full-service restaurant $445 to $745, MOB $475 to $640, biotech and life-sciences wet lab $1,100 to $1,850, industrial and warehouse $185 to $285, hotel select-service $345,000 to $485,000 per key, hotel full-service $725,000 to $1.05M per key, multifamily Type V wood-frame $345 to $465 per SF, and multifamily Type I-A high-rise $580 to $785 per SF. The metro tracks 18 to 28 percent above national driven by California prevailing wage, T24 Part 6 (most stringent energy code in the U.S.), CBC 2022 with San Diego municipal amendments, CASp / CBC 11B accessibility overlay, San Andreas and Rose Canyon seismic Zone D, biotech labor pull, CARB heavy-equipment fleet rules, DSD permit cycles of 9 to 18 months on commercial work, and Coastal Commission overlay on coastal projects. T24 Part 6 alone adds $8 to $22 per SF on commercial envelopes versus the IECC base used in most other states.
A venture-backed biotech tenant signed a 38,000 SF Class A lab lease in Sorrento Valley last spring, planning to consolidate three sub-leased footprints into a single corporate platform. The base building was a 2018-vintage shell built to Class A lab standards, the tenant team had a national lab architect, and the GMP came in at $42M — about $1,105 per SF — on a 11-month construction schedule. By month four, the program had grown: the founders added a vivarium for a small mouse colony, a BSL-2 wet lab expansion, and a cleanroom for downstream processing. The MEP density doubled in the floor plate. Then, at month seven, the T24 Part 6 commissioning agent flagged a lighting power density that exceeded the modeled allowance after the lab gas system was added, triggering a partial PV system increase and rooftop equipment screening rework on the envelope. The total project closed at $56.4M — roughly $1,485 per SF — including FF&E, lab equipment, and the T24 lighting/PV recompliance that added $32 per SF mid-project. The owner's preconstruction estimate had carried 8 percent contingency. The actual variance came in at 23 percent.
That same quarter, a national 3PL operator broke ground on a 285,000 SF distribution facility in Otay Mesa, designed to serve a Mexican-side OEM operations partner across the San Ysidro and Otay border crossings. The site was a flat industrial pad, the architect was local, and the GC ran an integrated design-build with the tenant's logistics consultant in the room from concept. Insulated metal panel install came in at $19 per SF supply-and-install on Kingspan polyiso panels, the dock package included 32 levelers and 16 truck restraints, and the entire ground-up tracked at $182 per SF over a 12-month build. The CARB Off-Road Equipment surcharge on Tier 4 Final loaders and excavators added roughly 6 percent to site work, and the DSD permit cycle ran 11 months from submittal to issued building permit. The project closed on schedule, on budget, and well below national distribution-facility benchmarks despite the California regulatory premium — proof that San Diego industrial in the right submarket and the right delivery method can outperform.
Those two anecdotes describe the same metro and almost the same year, but different cost universes. This article walks the 2026 cost framework an owner needs to scope a San Diego commercial project correctly, the building-type benchmarks the local GC market actually transacts at, the regulatory and labor drivers behind the premium, the submarket-by-submarket cost variation across the county, and the five recurring failure patterns that push San Diego projects sideways. None of this is intended as a substitute for a project-specific preconstruction estimate — every project has site, program, and timing variance that this guide can't capture — but the framework below is what should sit on the owner's preconstruction checklist before the first preliminary review submittal goes to DSD.
San Diego Metro 2026 — National vs. Local Cost Position
San Diego prices roughly 18 to 28 percent above the national commercial construction average across most product types in 2026, with biotech and life-sciences running an even larger premium because the labor pool and the specialized lab MEP scope sit in their own market. The national reference frame matters because it's what owners and lenders use to underwrite the project — the RSMeans 2026 City Cost Index, AGC's Q1 2026 Construction Inflation Alert, and ENR's Construction Cost Index all map regional indices to a national baseline of 100, and San Diego sits in the 118 to 128 band depending on the data set and the building type weighting. The Bay Area sits at 132 to 145, Los Angeles at 122 to 132, and the national median trades at 95 to 105.
The premium is structural — not market-cyclical. Even when commodity prices and steel come off, the San Diego cost position holds because the underlying drivers (prevailing wage, T24 Part 6, CBC 2022, seismic Zone D, CARB, DSD permit cycle) are regulatory rather than market. Owners moving from a Phoenix or Salt Lake City pro forma into a San Diego pro forma should rebase the per-SF assumption from the start. National rules of thumb — "Class A office runs $400 to $500 per SF" — don't translate. The right reference frame is a regional cost index calibrated to recent comparables in the specific submarket, not a national benchmark adjusted by a single multiplier.
For comparison across our metro guides, see Denver, CO, Las Vegas, NV, Dallas, TX, Atlanta, GA, Albany, NY, and Sheridan, WY — the cross-metro deltas show how California regulatory overhead reads against lower-cost jurisdictions on identical product types.
Cost by Building Type — San Diego County 2026
The bands below reflect ground-up construction in 2026 dollars, including hard cost, GC fee, general conditions, and bond/insurance, but excluding land, soft costs (A&E, permits, financing, FF&E unless noted), and tenant-specific equipment. Ranges represent the typical mid-quality-tier band — high-end finishes, signature design, and accelerated schedules push above the high end; spec-quality on flat sites with mature crews can clear below the low end.
Class A Office (Ground-Up)
Trophy and Class A office in UTC, Carmel Valley, Del Mar Heights, and Downtown. Premium for high-glazing curtain wall, T24 PV/battery, and seismic Zone D detailing. Tenant amenities and post-COVID HVAC drive the upper band.
Class B/C Office (Renovation)
Class B refresh and conversion in Mission Valley, Kearny Mesa, and Sorrento Mesa. Path-of-travel ADA / CBC 11B work and T24 lighting recompliance commonly drive 8–15% above the cosmetic base.
Retail (Inline / Anchor)
Anchor and mid-box retail at Mission Valley, Otay Ranch, and North County centers. Strip and freestanding pad retail trends to the low end. Coastal-zone retail (La Jolla, Pacific Beach) prices materially higher.
Restaurant (Full-Service)
Full-service ground-up restaurant or shell-to-finish second-gen. Chef-driven kitchen packages, Type I hood systems, and bar millwork at high end. QSR and fast-casual sit closer to $295–$425/SF.
Medical Office Building (MOB)
Multi-tenant MOB ground-up in Scripps, UCSD Health, Sharp, and Kaiser submarkets. HCAI compliance, medical gas, redundant power, and exam-room density drive the premium over Class A office.
Urgent Care (Fit-Out)
Urgent care fit-out in existing MOB shell. Imaging room shielding, medical gas distribution, and exam-room fit-out density. Branded fit-out (24-Hour, MedPost) sits closer to mid-range.
Dental Office (Fit-Out)
4–8 op dental practice fit-out in existing shell. Dental utility manifolds, plumbing density, and CASp / CBC 11B exam-room compliance. DSO/multi-location operators run lean fit-outs at the low end.
Biotech Wet Lab (TI in Class A Lab Shell)
BSL-1/BSL-2 wet lab fit-out in Sorrento Valley, Torrey Pines, UTC, or Carmel Valley Class A lab base building. 100% outside-air HVAC, lab gas distribution, fume hoods, casework. Mid-range tenants, FF&E inclusive.
Biotech Dry Lab / Computational
Dry lab and computational space — bench, cubicle, server-adjacent, and pilot bench. Less MEP-intense than wet lab. Common in mixed-program tenants who flex 30–40% wet / 60–70% dry.
Vivarium / BSL-3
Animal facilities and BSL-3 containment — pressure relationships, redundant HVAC, autoclaves, decon. Specialized GC, specialized commissioning, and AAALAC accreditation overhead. Limited cost data; tenant-specific scope.
Industrial / Warehouse (Ground-Up)
Tilt-up and PEMB ground-up distribution. Otay Mesa cross-border, Miramar, Kearny Mesa, and Vista submarkets. CBC seismic Zone D detailing and CARB equipment surcharge add to national base.
Cold Storage / Food-Grade
Refrigerated and freezer space with IMP envelope, ammonia or CO2 refrigeration, and dock packages. Cannabis-grade fit-out in coastal zones runs higher with security and HVAC overhead.
Hotel Select-Service
Hampton, Hilton Garden Inn, Holiday Inn Express, Courtyard tier ground-up or major repositioning. Brand-standard FF&E plus T24 envelope and parking structure where required.
Hotel Full-Service
Full-service Marriott, Hilton, Hyatt, Westin, and independent boutique tier. F&B program, ballroom, signature design, and coastal-zone overlays where applicable. La Jolla / Coronado/ Downtown waterfront prices at the high end.
Multifamily Type V (Wood-Frame)
Type V over Type I podium or all-Type V wood-frame to four stories. CBC 2022 wood-frame seismic detailing, T24 Part 6 envelope, and CALGreen Tier 1 compliance. North County and Chula Vista submarkets at lower end.
Multifamily Type I-A (High-Rise)
Type I-A concrete and steel high-rise residential, Downtown San Diego and East Village. Seismic Zone D performance-based design, full T24 PV/battery, and union labor with CA prevailing wage on PLA-bound projects.
K-12 School (DSA)
Division of the State Architect (DSA) review, Field Act compliance, full prevailing wage, and inspector of record (IOR) overhead. Modular and pre-engineered classroom delivery sits below the low end.
Life Sciences Class A Shell
Ground-up Class A lab shell built to lab-ready standards (slab loading, MEP capacity, structured ceiling height, redundancy infrastructure). Sorrento Valley, Torrey Pines, and UTC submarkets transact in this band.
Cross-reference the national baselines for these building types in Average Cost to Build a Medical Office Building (USA), Average Cost to Build a Cold Storage Facility (USA), Average Cost to Build a 3PL Logistics Warehouse (USA), and Distribution Center Construction Guide (2026). The deltas between national and San Diego specifically map the California regulatory premium.
What Drives San Diego Pricing Above National
The San Diego premium is the sum of nine identifiable, separately quantifiable drivers. Some are state-level (prevailing wage, T24 Part 6, CARB), some are county or city (DSD permit cycle, municipal amendments), and some are geographic (seismic, coastal). Each driver has a measurable effect on bid pricing, and most can be tested and managed at preconstruction if the team prices them honestly at design development.
California Prevailing Wage
California Department of Industrial Relations (DIR) prevailing wage applies to most public-funded commercial work and many privately funded projects through PLAs and local thresholds. All-trades wages run 30–55% above the BLS national OES median. Effect: 8–14% on hard cost.
Title 24 Part 6 Energy Code
Most stringent energy code in the U.S. The 2022 cycle (current) and 2025 cycle (effective Jan 1 2026) require performance compliance, PV/battery on most commercial occupancies, and electrification on water heating and most space heating. Effect: $8–$22/SF on envelope; $32–$48/SF on labs and high-glazing projects.
CBC 2022 + San Diego Municipal Amendments
California Building Code 2022 (Title 24 Part 2) with City of San Diego municipal amendments. Tighter occupancy classifications, stricter exiting on certain occupancies, and additional stormwater handling. Effect: 2–5% on hard cost depending on occupancy.
CASp / CBC Chapter 11B Accessibility
California's CBC 11B accessibility standard exceeds the federal 2010 ADA Standards on roughly 200 specific items — counter heights, parking dimensions, ramping ratios, restroom maneuvering clearances, and detectable warnings. Effect: 1–3% on hard cost on most projects, more on TI and second-gen takeovers.
San Andreas + Rose Canyon Seismic (Zone D)
San Diego sits in Seismic Design Category D. The Rose Canyon fault runs through downtown; the larger San Andreas system controls regional shaking. ASCE 7-22 seismic loads drive lateral system sizing, foundation, and detailing. Effect: 4–8% on structural and concrete versus low-seismic regions.
Biotech Crew Pull (Sorrento Valley + Torrey Pines)
San Diego runs the second-densest biotech construction cluster in North America after Boston/Cambridge. Major lab fit-outs on rolling cycles pull skilled mechanical, electrical, and clean-room labor away from non-lab projects. Effect: 90-day MEP rough-in delays during peak lab cycles; 5–12% labor premium on adjacent commercial.
CARB Off-Road Equipment Rules
California Air Resources Board (CARB) Off-Road Diesel Vehicle Regulation requires Tier 4 Final or zero-emission equipment fleets on most commercial sites. Equipment rental rates and daily costs run 12–22% above national. Effect: 4–9% on site work.
DSD Permit Cycle (9–18 Months Commercial)
City of San Diego Development Services Department commercial permit cycle commonly runs 9–18 months ground-up, 3–7 months TI. Discretionary, coastal, or AB 52 Tribal Cultural Resources review adds 6–12 months. Effect: soft-cost carry that flows into hard cost via escalation.
Coastal Commission Overlay
California Coastal Commission jurisdiction covers downtown San Diego, La Jolla, Pacific Beach, Mission Beach, Ocean Beach, Coronado, Imperial Beach, and Oceanside coastal frontage. Coastal Development Permit (CDP) adds 6–14 months and constrains design. Effect: schedule and entitlement risk; design rework if not handled at concept.
If you're moving a national prototype into San Diego from a non-California state, T24 Part 6 is the line item most likely to break the budget. The 2022 cycle requires PV and battery storage on most commercial occupancies above defined thresholds, full performance-based envelope compliance, daylighting controls, and lab-specific energy modeling. The 2025 cycle (in effect for new permits as of January 1, 2026) tightens further on electrification and lab energy. Owners pricing 2026 starts should run the 2025 numbers from concept and budget $8–$22/SF on the envelope as a starting position — climbing to $32–$48/SF on labs, high-glazing trophy office, and projects with weak orientation. T24 mid-project recompliance is the most common reason San Diego projects blow through their preconstruction allowance.

San Diego County is not a single cost market. The submarkets transact at materially different price points, driven by land cost flow-through, labor pool depth, entitlement complexity, and product-type concentration. The table below maps the recurring submarkets the local GC market actually prices into.
Downtown / East Village
High-rise multifamily, hotel full-service, Class A office. Type I-A concrete construction, performance-based seismic, full Coastal Commission overlay near the bay. Densest entitlement environment in the county.
Sorrento Valley (Biotech)
Biotech and life-sciences cluster. Lab fit-outs, Class A lab shells, R&D campuses. Specialized labor pool, MEP-density premium, and lab gas/HVAC overhead drive the largest premium in the county.
Carmel Valley / Del Mar Heights
Class A office, life-sciences spillover from Sorrento Valley, and luxury multifamily. One Paseo, Pacific Highlands Ranch, and Del Mar Heights office submarket. Trophy product transacts at the high end.
La Jolla / UTC
UTC mall area trophy retail, hotel, and office. La Jolla coastal-zone hospitality and high-end retail. UCSD Health and Scripps drive MOB demand. Coastal Commission applies on La Jolla coastal frontage.
Mission Valley
Class B/C office, retail, multifamily Type III/V, and hospitality. Snapdragon Stadium redevelopment, Civita master-planned community, and Riverwalk redevelopment. Inland — no Coastal Commission overlay.
Otay Mesa / Otay Ranch
Cross-border industrial, distribution, and 3PL. Larger sites, available labor, and proximity to Mexican-side OEM manufacturing. Lower land cost flows through to per-SF construction. Still carries CA regulatory premium.
Chula Vista
Multifamily Type V, retail, MOB, and select-service hospitality. Eastern Chula Vista master-planned communities and bayfront redevelopment. Bayfront projects carry Coastal Commission overlay.
Oceanside / North County Coastal
Multifamily Type V/III, hospitality, retail, and Class B office. Oceanside downtown redevelopment cycle and North County coastal hospitality. Coastal Commission overlay applies on coastal frontage.
North County Inland
Escondido, Vista, San Marcos, and Poway. Industrial, multifamily, and retail. Lower land cost, available labor pool, and no Coastal Commission overlay. CSU San Marcos and Palomar College drive education-adjacent demand.
Soft Costs and Permitting Timeline in San Diego
Soft costs on San Diego commercial projects routinely run 18 to 28 percent of hard cost — higher than the national 14 to 22 percent average — driven by entitlement complexity, T24 Part 6 modeling and commissioning overhead, CASp / CBC 11B review, and longer-tail design cycles when Coastal Commission or AB 52 Tribal Cultural Resources review applies. Owners benchmarking soft costs from a Phoenix or Salt Lake City pro forma should rebase from the start. See A&E Fees and Soft Costs in Commercial Construction (2026) and Commercial Construction Permitting Timeline by State (2026) for cross-jurisdiction frames.
DSD Permit Timeline by Project Type
The City of San Diego Development Services Department (DSD) commercial permit cycle is one of the longer in the country. The 2026 working assumptions are: ground-up commercial without coastal or discretionary overlays runs 9 to 14 months from initial submittal to issued building permit; ground-up with coastal or AB 52 review runs 12 to 24 months; tenant improvement without site work runs 3 to 7 months; signage and minor work runs 6 to 14 weeks. The plan-check cycle alone — first review to back-check approval — runs 60 to 120 calendar days on most commercial projects, with 2 to 4 review rounds typical.
Coastal Commission and Mello Act Overlays
The California Coastal Commission has jurisdiction over development within the Coastal Zone, which captures large parts of downtown, La Jolla, Pacific Beach, Mission Beach, Ocean Beach, Coronado, Imperial Beach, and the Oceanside coastline. Commercial projects in the Coastal Zone require a Coastal Development Permit (CDP) in addition to the standard DSD building permit. CDP review adds 6 to 14 months to entitlement, public hearing risk, and design constraints around view corridors, public access, and resource protection. The Mello Act layers on top in coastal zones for residential demolition or conversion involving low or moderate income units. Owners with coastal-zone projects should treat the Coastal Commission cycle as the schedule-driving line item, not the building permit.
Tribal Cultural Resources Review (AB 52)
California AB 52 (effective 2015) requires consultation with California Native American tribes during the CEQA process for projects with potential effects on tribal cultural resources. The lead agency must invite consultation with traditionally and culturally affiliated tribes within 14 days of determining a project requires an EIR, mitigated negative declaration, or negative declaration. AB 52 review is most relevant on projects that disturb soil — ground-up construction, deep utility work, foundation work — and on sites in or near identified tribal cultural resource areas. Effect on schedule: 2 to 8 months added to CEQA cycle. Effect on design: occasional resource-protection conditions of approval that constrain layout, depth of disturbance, or specific construction methods.
Where San Diego Projects Go Sideways — Five Failure Patterns
Across the TCG project portfolio and the AGC California cost data we benchmark against, five recurring failure patterns drive most San Diego cost overruns and schedule slips. Each is identifiable at preconstruction and preventable with disciplined estimating, but none is rare.
T24 Part 6 Late-Stage Envelope Rework
The energy model passes at design development and the project advances to construction. At commissioning, an envelope deficiency, lighting power overage, or HVAC underperformance triggers partial rework. Typical late-stage cost: $18–$35/SF. The fix: run the 2025 cycle numbers at concept, budget the envelope honestly, and engage the commissioning agent at design development.
CASp / CBC 11B Miss by Out-of-State Architect
An East Coast or Mountain West architect designs to the federal 2010 ADA Standards alone. CBC 11B catches the project at plan check on counter heights, parking, threshold ramping, and restroom maneuvering clearances. Schedule slips, change orders absorb the delta. The fix: engage a CASp at design development, not at construction documents.
Coastal Commission Permit Cycle Missed
The team treats the Coastal Development Permit as a parallel-track item rather than the schedule driver. CDP review adds 6–14 months and runs sequentially with — not parallel to — the DSD building permit on most projects. Soft-cost carry, escalation, and lender holding cost compound. The fix: treat CDP as the gating timeline; price escalation against a 12-month window minimum.
DSD Plan-Check Cycle Underestimated
The owner's pro forma assumes 4–6 months of permitting on a ground-up commercial project. DSD runs 9–18 months on most non-TI commercial work, with 2–4 review rounds typical. Lender holding cost and entitlement carry materially exceed budget. The fix: 12–14 months working assumption on downtown/coastal; 8–10 months on inland industrial.
Biotech Crew Availability Cycles
Major Sorrento Valley fit-outs hit construction simultaneously with non-lab MEP rough-ins on adjacent projects. Skilled mechanical, electrical, and clean-room labor flows toward the lab work. 90-day delays on non-lab MEP rough-in are common during peak biotech cycles. The fix: lock subcontractors to the schedule with deposit and milestone, not just signed agreement.
CARB Equipment Surcharge Underbudgeted
The site work bid uses national equipment rental rates. CARB Off-Road Equipment rules require Tier 4 Final or zero-emission fleets, and California rental rates run 12–22% above national. The bid comes in 4–9% high on site work, the owner negotiates, and the gap reappears as change order at mobilization. The fix: bid the equipment line at California rates from concept.
Material Lead Times and Labor Availability
San Diego material lead times track the West Coast pattern — generally 2 to 6 weeks longer than the national average on imported and engineered packages, slightly faster on commodity items because of port proximity. The recurring long-lead items in 2026: switchgear and substation equipment (52 to 78 weeks), cooling towers and chillers (28 to 44 weeks), elevators (38 to 56 weeks), structural steel (16 to 24 weeks), insulated metal panel (10 to 18 weeks for IMP from West Coast manufacturers), curtain wall (24 to 36 weeks), and lab casework (18 to 28 weeks for Sorrento Valley biotech). Cross-reference Commercial Construction Material Lead Times (2026) for the full national table.
Labor availability runs tight on a rolling cycle — every quarter has at least one trade where the local hall is over-subscribed. Mechanical and electrical trades run consistently tight because of biotech pull. Concrete and structural trades stay relatively available except during peak high-rise cycles downtown. Laborers and finishing trades vary with multifamily volume. The 2026 construction labor shortage pattern in California is structural — apprenticeship pipeline, retirement curve, and immigration policy interact — and shows up in San Diego as 5 to 12 percent labor escalation per year compounding through the cycle.
Delivery Method and Cost Variance
The delivery method choice — design-bid-build, design-build, or construction-manager-at-risk — drives cost variance materially in San Diego because the regulatory stack rewards integrated handoffs. Under design-bid-build, the architect designs the project, the owner bids it to GCs, and the GC inherits whatever's in the documents. T24 Part 6 modeling, CBC 11B compliance, and Coastal Commission conditions of approval are baked in by the time the GC sees the drawings — and any error in the design package shows up as a change order during construction. Under design-build delivery, the GC and the architect work under one contract from preconstruction forward, the regulatory stack is priced honestly at design development, and the GMP captures the full California overhead before the owner commits.
TCG project data across 38 states shows design-build delivery reduces cost variance from a typical 12 percent under design-bid-build to roughly 2 percent under integrated delivery on California projects specifically. The integration premium is bigger in California than in low-regulation states because the number of overlays — energy code, accessibility, seismic, coastal, tribal, prevailing wage — multiplies the handoff risk. Owners running a single San Diego project as a one-off can get away with design-bid-build if the architect and GC have deep San Diego experience. Owners running a portfolio rollout — multi-store retail, multi-site MOB, multi-asset multifamily — should standardize on design-build or CM-at-risk to avoid store-by-store variance.

Sector-Specific Considerations — San Diego 2026
Biotech and Life Sciences
San Diego is the second-largest biotech construction market in the U.S. after Boston/Cambridge, with active vacancy and absorption tracked quarterly by CBRE Life Sciences market reports and JLL San Diego industrial market reports. Sorrento Valley, Torrey Pines Mesa, UTC, and Carmel Valley anchor the cluster, with secondary nodes in Sorrento Mesa and Eastgate. Biotech vacancy in 2026 is in the 12 to 18 percent range — softer than the 4 to 6 percent peak of 2021–2022 but tightening on Class A space. Tenant fit-out scope ranges from a 5,000 SF startup wet lab to a 200,000 SF corporate consolidation. Specialized GC bench, lab commissioning expertise, and MEP density are the differentiators. See TCG's Life Sciences and Biotech Laboratories Construction service page for delivery framework.
Healthcare and MOB
Scripps, UC San Diego Health, Sharp HealthCare, Kaiser Permanente, and Rady Children's anchor the San Diego healthcare market, with a steady pipeline of MOB, ambulatory surgery, urgent care, and dental construction. HCAI (formerly OSHPD) compliance overhead, medical gas, redundant power, and exam-room fit-out density drive MOB pricing $475 to $640 per SF for ground-up, with surgery centers and imaging facilities running $625 to $920 per SF. Cross-reference national benchmarks at Average Cost to Build a Medical Office Building (USA) and TCG's Healthcare and MOB construction service.
Industrial and Cross-Border Logistics
Otay Mesa, San Ysidro, and the cross-border industrial corridor anchor San Diego's distribution and 3PL market. The Otay Mesa Port of Entry is the busiest commercial vehicle border crossing in California, and the planned Otay Mesa East crossing (in development) will add capacity. Industrial absorption tracks Mexican-side OEM manufacturing demand — automotive, electronics, medical device, and aerospace. Ground-up distribution facilities in 2026 run $185 to $285 per SF, with cold storage and food-grade running $345 to $565. IMP envelope is the dominant building skin for both standard distribution and cold storage — see TCG's IMP Install, IMP installation for cold storage, and IMP supply-and-install by state coverage.
Hospitality
San Diego hospitality construction is concentrated in downtown waterfront, Coronado, La Jolla, Mission Bay, and Oceanside. Coastal Commission overlay applies on most coastal hospitality projects and routinely controls the schedule. Select-service hotel ground-up runs $345,000 to $485,000 per key in 2026; full-service runs $725,000 to $1.05M per key. Brand-standard FF&E, public-area program, and back-of-house operational scope drive the variance within the band.
Price the California Stack at Concept, Not at Permit
The owners who run clean in San Diego are the ones who treat T24 Part 6, CBC 11B, Coastal Commission, prevailing wage, and CARB as line items at design development — not as contingency draws or last-minute change orders. Each one is identifiable, quantifiable, and bid-able at concept. None of them are surprises by month seven of construction.
The owners who get caught are running a national prototype, a national architect, and a national budget through a California permit cycle. The drawings pass design development. The plan check catches the CBC 11B miss. The commissioning agent catches the T24 lighting overage. The Coastal Commission appeals the CDP. Each step adds 30 to 90 days of schedule and 1 to 3 percent of hard cost. By month nine, the project is 18 percent over and three months late.
The fix isn't more contingency. It's better preconstruction. Hire a San Diego-experienced GC, architect, and CASp at concept. Run the 2025 T24 numbers from day one. Bid the equipment fleet at California rates. Treat the Coastal Commission cycle as the schedule driver. The cost of this discipline at preconstruction is 1 to 2 percent of project. The cost of skipping it shows up as 12 to 25 percent at closeout.
