Where the money goes: labor vs. materials
Across the 152 metros tracked, labor averages about 50% of a addition budget and materials about 50%. When you review a bid, judge its labor line against your metro's trade wages — the biggest source of overpricing we see — not a national average.
How we calculate these numbers
Every figure on this page is a blend of three independent cost sources — construction cost data (70%), homeowner-reported project spend (15%), and live U.S. Bureau of Labor Statistics trade wages (15%) — localized to each metro with a regional cost factor and a current-year escalation index. Ranges refresh as the underlying wage and materials data moves, which is why they're dated 2026 rather than recycled from older surveys.

Why does addition cost vary so much by city?
The same addition scope is priced differently across metros because of local trade wages, permit timelines, and material delivery costs. RemodelerIQ localizes every estimate using live 2026 BLS wage data for each metro rather than a single national average.
How do I know if my addition bid is fair?
Find your city below for the local 2026 range, then compare your contractor's bid against it. RemodelerIQ analyzes your actual PDF estimate against live local labor and material data for free, flagging padded scope and inflated margins.
How much of a addition cost is labor vs. materials?
Across the 152 metros tracked, labor averages about 50% of a addition budget and materials about 50%. The split shifts with finish level and local wages — which is why a bid's labor line should be judged against local rates, not national ones.
Do I need a permit for a addition?
