How big is a tiny house?

Under IRC Appendix Q a tiny house has at most 400 sq ft of floor, not counting lofts. Plenty of people use the word for homes up to about 800 sq ft, so this page shows what 600 and 806 sq ft give you next to our 400 sq ft plans.

1 bed small home, 16 × 37.5 ft

Long and narrow like a park model: the living room and kitchen take one end, and a little entry hall leads past the bathroom to a bedroom with a long closet at the other.

2 bed small home, 26 × 31 ft

Almost square, so it feels like a small house rather than a trailer. Living room and kitchen across the front; two bedrooms flank a short hall that ends at the bathroom.

What counts

What counts in the square footage

Both homes here stand on a foundation and have no loft, so every room counts and the total is just the outside measure: 600 sq ft for the long one bedroom, 806 sq ft for the two bedroom. Above 400 sq ft a home falls under the regular code instead of the tiny house appendix.

Each room is measured inside its walls. The finished area of a house is measured to the outside of the exterior walls (ANSI Z765), so it is larger than the rooms added up.

Questions

How big is a tiny house: questions

About these tiny house sizes plans. Can’t find your answer? Send us a message.

What does 400 sq feet look like?

About one room of 20 by 20 ft, the size of a two-car garage. That holds a living room with a kitchen, a bedroom and a bathroom; the 20 × 20 plan on our 400 sq ft tiny house page shows how.

Is 400 sq ft a tiny home?

Yes. 400 sq ft is the top of the range in IRC Appendix Q, and a loft on top of that floor does not count toward the number.

Is a 1,000 sq ft home tiny?

Not by the code. At 1,000 sq ft there is room for two or three bedrooms, and most people call that a small house. Our small house plans show what that size looks like.

Can I change these plans?

Yes. Click Open in the editor under a plan and it opens as your own plan in the Squaremetry editor, with the same numbers as on this page. Move a wall and every area and the total update.

Is this a construction drawing?

No. This is an example floor plan, not a construction drawing. The Squaremetry team drew it for this page; it has no address. For a permit you need drawings from a qualified designer.
