Multifamily construction cost data is widely published, consistently misused, and routinely misunderstood. National cost databases publish square footage cost ranges that obscure the most important determinants of what a specific project will actually cost, the project type, the market, the site conditions, the specification level, and the timing of construction relative to the regional subcontractor market cycle. A developer who builds their pro forma on a published cost range without adjusting for those factors will produce a feasibility analysis that is wrong in ways that show up during contractor selection or, worse, during construction.
The following is a realistic breakdown of multifamily construction costs by project type, with regional context for the markets Innergy Integral serves.
Wood-Frame Low-Rise: The Most Forgiving Structure
Wood-frame low-rise construction, three to five stories of wood framing, typically on a concrete slab or a minimal podium, is the least expensive multifamily structure type and the one where regional cost variation is most pronounced. Because wood-frame residential construction is the dominant activity in most markets, local subcontractor competition is deepest and costs are most responsive to local market conditions.
In Spokane, El Paso, and Albuquerque, markets with competitive local residential subcontractor bases and lower labor costs than the coastal markets, wood-frame low-rise hard costs (excluding land, soft costs, and financing) run $160 to $195 per square foot of gross buildable area in 2026. In Tacoma and the south Puget Sound, costs run $210 to $240. In Seattle and Bellevue, wood-frame residential costs run $240 to $285, driven by higher labor rates, more demanding design standards, and a subcontractor market under sustained competitive pressure.
The line items that most commonly exceed their budget in wood-frame construction: site work (geotechnical surprises, utility connections, stormwater requirements that exceed initial estimates); framing labor (productivity assumptions that don’t reflect current labor availability); and finish work (allowances that don’t reflect the market-standard specification level the project actually needs).
Podium Mid-Rise: Where the Cost Complexity Increases
Podium construction, wood framing above a concrete podium that typically houses parking, retail, or amenity space, is the dominant product type for urban infill multifamily across most of Innergy Integral’s service area. The structural complexity is greater than wood-frame low-rise, the MEP systems are more sophisticated, and the construction sequence requires careful coordination between the concrete podium phase and the wood-frame residential phase above.
Hard costs for a standard five-over-two podium (five stories of wood-frame residential over two levels of concrete podium) in Phoenix and Tucson run $225 to $265 per square foot. In DFW, similar projects run $240 to $280. In Denver, $260 to $310. In Seattle, podium construction runs $320 to $395, reflecting the Puget Sound’s labor costs, design complexity requirements, and the sustained high construction volume that has pushed subcontractor pricing above what comparable markets support.
The podium-to-wood-frame interface is the construction phase that most commonly produces both quality issues and cost overruns. Coordination between the concrete subcontractor completing the podium and the framing subcontractor who begins above-grade residential work requires careful sequencing that affects both schedule and cost. Projects that do not have an experienced construction manager or owner’s representative actively managing this interface consistently encounter problems at this transition.
Structured parking adds cost that many developers underestimate. A below-grade parking level adds $35,000 to $55,000 per space in most markets, more in markets with difficult soils or high water tables. An above-grade structured parking level adds $25,000 to $40,000 per space. Surface parking eliminates the structure cost but reduces the site’s density, affecting the project’s overall economics.
Concrete High-Rise: The Cost Premium Is Real
Concrete high-rise construction, 12 stories and above, or any project where the structural system is post-tensioned concrete rather than wood framing, carries a cost premium over podium construction that developers from lower-height markets consistently underestimate. The structural system is more expensive per square foot. The MEP systems are more complex. The general conditions, crane rental, hoisting, site logistics in an urban setting, are substantially higher than comparable low-rise or mid-rise projects.
In Bellevue, Seattle, and Denver, concrete high-rise hard costs run $400 to $525 per square foot for market-rate residential. Luxury high-rise with premium finishes runs higher. The elevator count and elevator specification, high-rise buildings require more elevators and higher-speed, higher-capacity elevator systems than low-rise or mid-rise, is a meaningful cost driver that some budgets address with inadequate allowances.
High-rise construction also has longer schedules than low-rise and mid-rise, 24 to 36 months for a typical 20-to-30-story residential tower, which means more months of general conditions cost, more months of interest reserve consumption, and a longer period of carrying cost before the project generates revenue.
The Line Items That Most Commonly Overrun
Across all project types and markets, five cost categories account for the majority of budget overruns:
General conditions. The project overhead costs, superintendent, project manager, temporary facilities, equipment, utilities, cleaning, are often estimated as a percentage of the hard cost rather than built up from first principles. When the project schedule extends, general conditions run longer than the percentage-based estimate assumed.
Concrete. Concrete pricing has been volatile across construction cycles, and projects that were bid during lower-cost periods and constructed during higher-cost periods face concrete cost increases that affect both the structural scope and the flatwork.
MEP. Mechanical, electrical, and plumbing systems are consistently the most difficult scope to estimate accurately from preliminary plans, and the most common source of significant cost discoveries during design development and bidding.
Contingency drawdown. Projects that enter construction with inadequate contingency, less than 5% of hard cost for a well-documented project, less than 10% for a project with incomplete or ambiguous construction documents, run out of contingency before they run out of unforeseen conditions.
Site work. Geotechnical surprises, utility conflicts, stormwater requirements, and off-site improvement requirements that were not fully known at budget time routinely produce site work cost increases.
Innergy Integral’s pre-closing plan and cost reviews for construction lenders and pre-construction budget reviews for developers assess each of these categories against current market conditions before the project commits to its cost basis.
