What structural work actually costs
Across the structural projects priced here, jobs run from $300 at the low end to $300,000 at the top. The cheapest thing on this page is attic ladder installation; the most expensive is second story addition.
Most of this work is priced by the carpenter doing it: labor is about 54% of the typical bill in this category. That is the part that changes when you change cities, which is why two identical quotes in different metros can be hundreds apart on the same materials. Every guide below carries its own city-by-city breakdown built from BLS wage data.
Ranges are typical all-in costs for a standard job, not quotes. Read the individual guide for the tier breakdown, what drives the price on that specific project, and where the money is worth spending. See how we build these numbers.
