Aldo build-cost reference

What it costs to build, county by county

Construction cost is the other half of whether a parcel pencils - and like zoning, it moves the moment you cross a county line. A standard-finish build runs $242–$318/sq ft in Westchester County and $191–$250/sq ft in Delaware County. Every number here comes from the same cost engine Aldo uses to price a real parcel, broken out by system, foundation, site and season. Pick a county.

Cost to build by town

The county index sets the build rate, but the town sets what you have to buy to use it - its own minimum lot size, its own coverage cap, its own land prices. We price both for 367 towns and cities, house and accessory unit:

Building somewhere specific? Every county also has a zoning breakdown by town - what you can build before you price how much it costs.
