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.

Permits and engineering
The drawing set is organized the way building departments expect: cover sheet with code and load notes, plans, elevations, a section, foundation, framing, electrical and plumbing. Many jurisdictions will also ask for a local engineer's or architect's stamp, energy-code forms or a site plan, so plan for that review.
