Regulations

Good to know before you ask

Several states, including California, Oregon and Washington, have passed laws that make it easier to build accessory dwelling units, and many cities have loosened their rules. Size, setbacks, parking and owner-occupancy rules still vary by city.

An ADU needs a building permit and must meet the building code. Ask builders how they handle utilities, permits and inspections. We do not build ourselves and do not show prices.

FAQ

Frequently asked questions

What is an ADU?

An accessory dwelling unit is a second, smaller home on the same lot as a house: a backyard cottage, a garage conversion or an in-law apartment.

Can I build an ADU on my lot?

It depends on your state and city rules: zoning, lot size, setbacks and utilities. Your city's planning department publishes its ADU rules.

Can I rent out my ADU?

In many places yes, sometimes with limits on short-term rentals. Check local rules before you build.
