Do You Have Questions About Accessory Dwelling Units?

Building an ADU on your property is a big decision, and we want you to have the information you need to make the right choice. Here are the answers to a few questions we often receive.

In Phoenix, every single-family detached lot is permitted one ADU in addition to the primary dwelling unit. Homes with an attached dwelling unit, duplexes, and multi-family dwelling units are not eligible to build an ADU.

An ADU can serve many purposes such a guest house for friends or a permanent living space for aging relatives. ADUs can also be used as rental space for long-term tenants. 

Choosing between a detached or attached accessory dwelling unit will depend on your lot and how you plan to use the unit. A detached unit typically provides more privacy for residents which may be preferable for long-term tenants.

Yes, there are various financing options available for building an ADU. These can include home equity loans, construction loans, or refinancing your mortgage. Some financial institutions also offer specific ADU financing products.

Larger lots can have an ADU of up to 3,000 square feet. In both cases, the ADU can be no larger than 75% of the gross floor area of the primary dwelling unit.
