What will Plan 12-2439 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 240 sq ft house like Plan 12-2439 generally falls between $36,000 and $79,200 owner-built, or $60,000 to $120,000 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 (slab or piers), 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.
