Overview

What Goes Into a Tiny Home Build?

Tiny homes pack a surprisingly complex build into under 400 square feet. Whether you're building on a foundation or a trailer (THOW), the structural, electrical, and plumbing requirements are the same as any home — just smaller. Efficient layout planning and precise material lists matter even more when you're working with limited space.

Permits & Codes

What to Know About Permitting

Foundation tiny homes are permitted as conventional structures in most jurisdictions. Trailer-based tiny homes (THOWs) fall into a regulatory gray area — some states classify them as RVs, others as manufactured housing. Check your local zoning for minimum square footage requirements.

FAQ

Common Questions About Tiny Homes

What's the difference between a tiny home on wheels and a foundation tiny home?

A THOW (Tiny House on Wheels) is built on a trailer and classified as a vehicle in many states. A foundation tiny home is a permanent structure subject to standard building codes.

Can I put a tiny home on my existing property as an ADU?

In many jurisdictions, yes — ADU rules have relaxed significantly in recent years. A tiny home as an ADU typically needs to meet local setback, utility connection, and minimum size requirements.
