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.
