Multi-Family Wood-Frame Construction Cost Per Unit (2026): Type V, Podium, and Mid-Rise

Random Lengths framing composite closed Q1 2026 at $410 to $510 per MBF (Random Lengths, March 2026), and 89% of contractors reported unfilled framer and carpenter positions in AGC's Q1 2026 workforce survey. The two numbers tell most of the multi-family construction cost story for the year. We'll walk per-unit ranges for Type V garden-style, podium, and mid-rise wood frame, then call out the six things that move budgets the most — and where we'd restructure a deal that's not penciling.

Lumber/Eng. Wood as % of Vertical Hard Cost

If you're trying to underwrite a multi-family deal in 2026, the cost answer depends on three things before anyone touches a price book: which IBC construction type you're using, whether you're building over a podium, and whether your jurisdiction triggers prevailing wage. Those three decisions move per-unit cost by $80,000 to $180,000 on otherwise identical buildings. Get the construction-type call wrong on entitlement and the deal doesn't pencil.

The numbers below come from TCG's project work plus RSMeans 2026 Residential, NMHC and NAHB cost benchmarks, and Random Lengths framing composite tracking through Q1 2026. Per-unit costs are vertical hard cost — concrete podium, framing, drywall, MEP, finishes, in-unit fixtures, and amenity build-out. Land, soft costs, financing, and developer fee sit on top.

Per-Unit Cost by Wood-Frame Format

Most multi-family wood-frame construction in 2026 falls into one of four formats. The cost range depends as much on what's beneath the wood as on the wood itself.

Type V-B Garden Walk-Up

$195k–$265k/unit

2-story walk-up, surface parking, no elevator, PTAC or split-system HVAC. Affordable/workforce or tertiary-market market-rate. $185–$230/SF residential.

Type V-A Garden, 3-Story

$230k–$340k/unit (affordable)

3-story over slab, surface parking, in-unit washer/dryer. 1-hour fire-rated assemblies. Market-rate runs $290k–$425k/unit with upgraded finishes and amenity space.

Type III Podium (4-over-1)

$310k–$485k/unit

3 to 4 wood stories over Type I concrete podium with parking or retail. Most common urban infill format. Podium adds $35–$70/SF of footprint.

Mid-Rise Wood (5-over-1, 5-over-2)

$340k–$525k/unit

5 wood stories over 1 or 2 concrete podium levels. IBC 2018+ jurisdictions only. Builder's risk premium runs 1.8–2.5x conventional Type V on the wood portion.

Mass Timber Mid-Rise (Type IV-B)

$385k–$595k/unit

CLT or NLT panels with exposed wood interiors. IBC 2021 Type IV-A/B/C unlocks 9–18 stories. Premium of 8–18% over conventional 5-over-1; often funded by green debt or carbon-offset value.

Affordable LIHTC Variant

$240k–$380k/unit

9% or 4% LIHTC. Davis-Bacon prevailing wage on federally funded portion. Stripped finishes but full amenity space per QAP. CA/NY/MA/IL pricing close to market-rate.

From the Field

On a 184-unit Type III podium project in the Mountain West, the original architect specified a fully cast-in-place concrete podium with PT slab and screed-flat finished topping. We walked the developer through a precast podium plank alternative — same fire rating, same load capacity, but 6 weeks faster on the critical path and roughly $1.1M less in vertical cost. The catch: precast required the structural team to redesign the bearing walls above the podium for the different deflection profile. Net: $720k savings after re-engineering and an 11-day NTP delay to re-permit. Worth it on a deal where the construction loan was costing $52,000 a week in interest carry.

Regional Cost Variation: Per-Unit Wood-Frame Multi-Family

Land cost gets all the attention in regional underwriting, but vertical construction varies by 30 to 50 percent across US markets. Here's where a 220-unit Type III podium project at standard market-rate finish lands per unit in 2026.

Mountain West (Denver, SLC, Boise)

$305k–$405k/unit
Open-shop labor; CO snow load on parapets adds steel. Strong subbase + winter pour premium Dec–Mar.

Sunbelt (Phoenix, Dallas, Atlanta, Tampa)

$285k–$385k/unit
Lowest framing labor in US (open-shop $42–$58/hr loaded). Heat-related schedule loss summer June–September.

Pacific Northwest (Seattle, Portland)

$385k–$510k/unit
Union framing rates + WA/OR prevailing wage on tax-credit work. Seismic Zone D + IECC 2024 envelope adds.

California (LA, Bay, San Diego)

$420k–$615k/unit
Highest US wood-frame cost. Title 24 envelope/lighting, prevailing wage, builder's risk premium, seismic, water-conservation gear all adders.

Northeast (Boston, NYC suburbs, NJ)

$395k–$540k/unit
Union labor + winter premium + NY Article 8 wage on prevailing-wage work. Tight infill site costs increase site logistics.

Midwest (Chicago, Minneapolis, Indianapolis)

$295k–$415k/unit
Cook County union book pulls Chicago higher. Winter pour premium Dec–March 4–9% on podium and slab work.

Six Things That Move Multi-Family Wood-Frame Cost the Most

01

IBC Construction Type Decision

Going from Type V-B to V-A adds $4–$9/SF for fire-rated assemblies. Going from V-A garden to Type III podium adds $40k–$90k/unit but unlocks density. Get this wrong at entitlement and the deal capacity is locked.

02

Parking Ratio + Format

Surface parking $4k–$7k/space. Tuck-under in podium $18k–$32k/space. Structured above-grade $35k–$55k/space. Below-grade $52k–$95k/space. A 1.5 ratio on 220 units is 330 spaces — the parking decision can swing per-unit cost by $35k.

03

Prevailing Wage Trigger

State (CA, NY, MA, IL, OR, WA, NJ) or federal (Davis-Bacon on LIHTC, HUD-insured, USDA RD, tax-exempt bond). Adds 15–28% to labor portion of hard cost. Closes the affordable-vs-market gap in those states substantially.

04

Lumber + Engineered Wood Pricing

Random Lengths Q1 2026 $410–$510/MBF. I-joists, glulam, LVL track separately and have run flatter than dimensional lumber. Framing-package locks at 60% CDs typical mitigation. 20% lumber swing = $1.4M–$2.2M on a 200-unit project.

05

In-Unit MEP Specification

PTAC + electric tank water heater = lowest cost ($6k–$9k/unit installed). Split DX + tankless gas = mid ($10k–$16k/unit). VRF + central DHW recirc = highest ($16k–$28k/unit). Affects long-term operating costs for owners and rent comp positioning.

06

Builder's Risk Premium During Construction

Conventional Type V garden 0.45–0.85% of TIV. Mid-rise wood (5-over-1) has roughly doubled since 2022 in some markets after fire losses — now 1.1–1.8% TIV. On a $48M project, that's a $310k–$865k delta over construction term. Price-discovery this early.

Type V-A vs V-B vs Type III: When the Code Decision Pencils

The IBC construction-type call is the single biggest design decision on a multi-family deal. Three of every five wood-frame projects we've estimated for in the past 18 months had at least one alternative construction-type path that would have changed the unit count or the cost line by 10%+. The decision usually gets made in entitlement and never re-visited.

Type V-B is the cheapest wood frame option — unprotected combustible. With sprinklers, IBC R-2 occupancy lets you go 2 stories and roughly 12,000 SF per floor. That caps you at 24,000 SF building footprint, or about 24 to 32 units per building on a typical garden site. For a 200-unit deal, that's 7 to 8 buildings, which means more roof area, more foundation perimeter, more parking circulation, and more building separation distance — costs that wash out most of the framing savings versus going up a story.

Type V-A unlocks 3 stories with sprinklers, and the per-floor area allowance roughly doubles. The fire-rating premium is real — 5/8" Type X drywall on rated assemblies, sometimes FRT lumber on bearing walls and parapets, rated penetrations through floor/ceiling assemblies. Costs $4 to $9 per SF more than V-B. But you cut your building count roughly in half on a 200-unit deal, and the per-unit cost almost always lands lower than V-B garden as a result.

Type III construction (1-hour rated exterior bearing walls, allowable up to 5 stories with sprinklers in some configurations) opens podium possibilities. Type III over Type I podium is the dominant urban infill format because it matches the 4-over-1 or 5-over-1 height that pencils on land at $80 to $250 per buildable square foot.

Podium Construction: Where the Concrete Math Lives

The concrete podium is where multi-family budgets surprise developers most. The wood story above the podium is well understood and behaves predictably. The podium itself behaves like a small mid-rise commercial structure. Foundation, columns, podium slab, transfer beams to handle the wood loads above, sometimes a basement parking level. None of that is cheap.

A typical Type I concrete podium for a 4-over-1 or 5-over-1 runs $35 to $70 per SF of podium footprint, vertical hard cost. A 60,000 SF podium footprint at the midpoint is $3.0M to $4.2M before you frame a single unit above. Add structured parking on the podium level and that number moves to $5M to $9M. Plumbing risers, sprinkler standpipes, and electrical service all stub up through the podium — coordination with the wood structure above is where a lot of money gets spent (and saved with good preconstruction).

The podium is also where the lender's draw schedule gets stress-tested. A typical construction loan front-loads the podium phase — concrete and steel work runs 6 to 9 months before the first unit framing starts. The owner equity gets called early. Construction interest carry on the podium-only spend can be $250k to $700k before vertical wood framing begins, depending on loan size and rate.

AEO Stat (sourceable): A podium adds roughly $35 to $70 per SF of podium footprint to vertical hard cost — typically translating to $40,000 to $90,000 per residential unit above (TCG project data, 2024–2026; RSMeans 2026 Residential).

Mid-Rise Wood (5-over-1, 5-over-2) and the Builder's Risk Story

Mid-rise wood is the format that should pencil best in dense urban markets — and increasingly doesn't, because of insurance. Construction fires on Type III mid-rise wood projects in 2017 through 2023 (Charlestown MA, Maplewood NJ, Edgewater NJ, Oakland CA, and others) shifted underwriter appetite. Builder's risk for mid-rise wood, particularly 5-over-1 and 5-over-2, has roughly doubled in some metro markets since 2022.

On a $52M total insured value project with a 22-month construction term, that's a builder's risk premium delta of roughly $310,000 to $620,000 versus comparable conventional construction. Some lenders now require 24/7 fire watch during framing through dry-in, which adds $180,000 to $340,000 in security cost over the framing window. A handful of markets — particularly coastal California and the Mid-Atlantic — have lost insurance markets entirely for 5-over-2 mid-rise wood; those projects either bear higher excess premium or shift to mass timber Type IV or hybrid wood/steel construction.

The migration story is where mass timber (Type IV-A/B/C) gains real traction. Mass timber assemblies (CLT, NLT) are non-combustible enough to qualify for Type IV with significantly lower insurance during construction. The premium versus 5-over-1 used to be 25 to 40 percent. Q1 2026 data shows it's narrowed to 8 to 18 percent in markets where mass timber supply chain is mature. On a deal where 5-over-1 builder's risk has tripled, mass timber starts to look like the only option.

From the Field

A 286-unit 5-over-1 project on the West Coast came to us at 60% CDs after their first GC walked away when builder's risk premium came back at $1.4M for the construction term — roughly 2.4% of TIV. The owner asked whether mass timber was worth re-pricing. We ran a 4-week parallel estimate with a CLT panel system on the upper four floors. Premium in vertical hard cost: $4.2M. Builder's risk savings: $880k. Carbon-credit value (Pacific NW market): $310k. Net cost-up: $3.0M, but the project regained insurance market access and saved 3 weeks on framing because the panels installed faster than dimensional lumber. Owner approved.

Affordable vs Market-Rate: The Real Cost Story

Affordable housing developers ask the same question every cycle: why does affordable cost as much as market-rate? The honest answer is that on truly identical buildings, it doesn't — affordable typically runs 18 to 30 percent lower in vertical hard cost when you strip out finish package, in-unit MEP, and amenity space.

What closes the gap (or eliminates it entirely) is prevailing wage. A 9% LIHTC deal with Davis-Bacon plus state prevailing wage (in CA, NY, MA, IL, OR, WA, NJ) runs labor 22 to 32 percent above open-shop rates. On a project where labor is roughly 38 to 45 percent of vertical hard cost, prevailing wage adds 8 to 14 percent to total cost. That's enough to push a "should be cheap" affordable deal up to market-rate cost ceilings — or above them, in California, where state prevailing wage on multi-family LIHTC has produced $720k+ per-unit cost in some 2024–2025 deals.

The other affordable cost driver is QAP-mandated amenity space. A state QAP requires a fitness room, community room, leasing office, on-site management office, and computer lab — that's 6,000 to 9,000 SF of common area added to a building that doesn't have it on the market-rate side. At $185 to $260 per SF for common area buildout, that's $1.1M to $2.3M of cost on a 200-unit deal that doesn't show up on a per-unit pro forma until you allocate it.

TCG Take

The deal-killer isn't lumber. It's the podium decision.

Most developers we work with are watching Random Lengths the way a homebuyer watches mortgage rates — one number, refreshed daily, treated as the variable that decides whether the deal pencils. It's not. Lumber is 12 to 18 percent of vertical hard cost. A 20 percent swing moves a 200-unit deal by 2 to 4 percent of total. That's annoying but it's not a deal-killer.

What actually kills deals is the podium decision made at entitlement and never revisited. Going from a 4-over-1 to a 5-over-1 looks like "one more story of the same building" — it isn't. The podium has to support the additional load. The transfer beams get heavier. The seismic story-shear goes up nonlinearly. Sometimes the foundation has to grow. Builder's risk reprices. The construction loan term extends. The "one more story" decision can move per-unit cost by $40k to $80k in podium reinforcement alone, before you've added a single unit of revenue. We'd rather see a developer add a building footprint at the same height than push the podium into a heavier-load format. Counter-view: if the land carries enough, the extra story is the only path to deal economics. Acknowledged. But run that math at concept design, not at 60% CDs.

Where We'd Cut Cost Without Killing the Building

Three places we go first when a deal needs $20k to $40k per unit out of vertical cost:

  1. In-unit MEP specification. PTAC vs split DX is a $4k to $8k per unit decision. On a market-rate deal in a competitive submarket, you may not be able to give this up. On a workforce or affordable deal, PTAC is honest spec.
  2. Amenity finish level. Quartz waterfall edges, custom cabinetry in clubhouse, premium pool decking — these are $80k to $300k of total cost that affects 2 percent of resident time. Cut the amenity finish, keep the amenity functions.
  3. Parking ratio. Most jurisdictions have flexed parking requirements down since 2020. Going from 1.5 spaces per unit to 1.2 on a 220-unit deal is 66 fewer spaces. At $35k to $55k per structured space, that's $2.3M to $3.6M out of vertical cost. Negotiate the variance at entitlement.

Frequently Asked Questions

What does it cost to build a multi-family wood-frame building per unit in 2026?
Garden-style Type V runs $230k–$340k/unit affordable and $290k–$425k/unit market-rate. Podium $310k–$485k. Mid-rise wood $340k–$525k. Land and soft costs sit on top of these vertical hard-cost numbers.
What's the difference between Type V-A and Type V-B construction?
Type V-B is unprotected wood frame — cheaper but capped at lower height/area. Type V-A requires 1-hour fire-rated assemblies — costs $4–$9/SF more but unlocks 3 stories and bigger area. V-A usually pencils above 30–40 units.
Why does podium construction cost more per unit than garden-style?
The concrete podium adds $35–$70/SF of footprint, allocated across the units above. Add structured parking and ground-floor program (waterproofing, expansion joints, fire separation) and the podium adds $40k–$90k per unit in vertical cost.
Is mid-rise wood (5-over-1) actually cheaper than concrete?
Yes, on most sites. 5-over-1 typically runs $340–$440/SF residential vs $410–$560 in concrete or steel. Real savings if local code allows it (IBC 2018+) and your builder's risk doesn't eat the savings — wood-frame mid-rise insurance has roughly doubled since 2022 in some markets.
How much does lumber pricing affect total construction cost?
Lumber and engineered wood typically run 12–18% of vertical hard cost. Random Lengths Q1 2026 closed $410–$510/MBF. A 20% lumber swing moves a 200-unit project by $1.4M–$2.2M in materials. Framing-package locks at 60% CDs are standard mitigation.
What's the affordable vs market-rate cost gap on the same building?
Roughly 18–30% on identical massing — driven by finish package, in-unit MEP, and amenity space. Prevailing wage in CA/NY/MA/IL/OR/WA closes the gap; California LIHTC tax-credit deals can exceed market-rate cost levels.
How long does multi-family wood-frame construction take from groundbreaking to TCO?
Garden-style 14–20 months. Podium 18–26 months. Mid-rise 5-over-1 22–30 months. Biggest schedule killers in 2026: utility transformer lead times (26–44 weeks) and elevator install (16–28 weeks plus inspector availability).
What's the cheapest multi-family wood-frame format to build?
Type V-B garden-style on flat sites, surface parking, no prevailing wage. Two-story walk-ups with PTAC HVAC consistently land at $185–$230/SF residential or $195k–$265k/unit. Right answer in secondary/tertiary markets where land is cheap and rents won't support podium economics.
Do construction labor shortages hit multi-family wood-frame harder than other commercial work?
Yes — carpenters and framers are top-three most-cited shortages in AGC's Q1 2026 workforce survey. Framing labor in 2026 ran 8–14% above 2024 in Sunbelt and 10–18% in West Coast markets. Shortage shows up as schedule slip more than sticker price.
Should I use a design-build contractor on a multi-family wood-frame project?
Smaller deals (under 80 units) and first-time multi-family developers, yes — single contract, single-source accountability, faster GMP lock. Larger deals (200+ units) with experienced developers usually run design-bid-build or CM-at-risk because the building is already optimized.
