What is an ADU?

ADU's in arizona

Thinking about adding an ADU (Accessory Dwelling Unit) to your property? Here’s what you need to know about ADUs in Arizona:

First off, what exactly is an ADU? It’s basically a secondary living space on your property that’s independent from your main home. There are a few types: detached (separate from the main house), attached (connected to the main house), converted (repurposed space within the main house), and junior (a smaller, self-contained unit within the main house).

Now, let’s talk regulations. In Arizona, municipalities with a population of over 75,000 are required to allow at least one type of ADU on any lot where a single-family dwelling is permitted. This could be attached, detached, or internal. Plus, they have to permit additional ADUs for every restricted-affordable unit on the property.

Some key points to note:


  • Your ADU can’t exceed 75% of the floor area of your main house or 1,000 square feet, whichever is less.
  • Municipalities can’t stop you from leasing out your ADU separately from your main house.

  • They also can’t impose requirements like familial or employment relationships between the owner and occupants.
  • And they can’t make you match the design of your ADU to your main house.

It’s worth mentioning that while there are statewide regulations, some specifics may vary depending on where you live. So, it’s a good idea to check with your local authorities or zoning department to make sure you’re up to date with any additional requirements in your area.
