What will Plan 12-2424 cost to build?
Using typical 2026 costs of $150–$330 per sq ft for an owner-built home and $250–$500 per sq ft with a builder, a 728 sq ft house like Plan 12-2424 generally falls between $109,200 and $240,240 owner-built, or $182,000 to $364,000 with a general contractor, before land, utilities and site work. Your region, finishes and foundation move the number most.
Where this plan works
This plan is designed for a permanent foundation (crawlspace or slab), so it is reviewed like any other small house. Where local rules allow units of this size, it can also serve as an ADU or backyard cottage. Check tiny house zoning rules and minimum dwelling sizes in your county before you build.
