Phoenix residents citywide can now begin building backyard casitas or guesthouses, since the legalization that the City Council approved in September became effective Nov. 6.
The legalization expanded permission to build attached or detached accessory dwelling units, or ADUs, to all single-family residential homes in Phoenix.
Previously, only larger lot homes could build guesthouses. City Council says the change is intended to improve affordable housing options, in particular by giving families the option to house adult children or aging grandparents in livable units.
City officials say approximately 20 residents have shown up at City Hall so far to begin the process or learn more about it.
After passing the ordinance, Councilwoman Debra Stark asked the city planning department to publish a guide on how to start the ADU process.
That guide hasn’t been released yet, but Planning and Development Department Deputy Director Tricia Gomes gave The Arizona Republic a rundown of what residents can expect.
Here’s what to know.

Step 1: Draft site plan
A draft plan or site plan will need to be submitted to Shape Phoenix, a webpage on the city’s planning department website. Or, it can be submitted in person at City Hall. An appointment is needed to enter City Hall.
Information about site plans can be found on the “Technical Documents (TRT)” page of Phoenix’s planning website, Gomes said.
Step 2: Zoning review
The city will review the plan to ensure it complies with Phoenix zoning rules. Once complete, the city’s residential counter takes over, Gomes said.
Step 3: Residential counter will issue building permit
A building plan will need to be submitted. The residential team will review the plan to ensure the casita complies with Phoenix’s building codes. Once complete, a building permit will be issued.

Step 4: Inspection
The city will conduct multiple inspections throughout the construction process. How many depends on the specifics of each project.
Step 5: Certificate of occupancy
The final sign-off from the city is issuing a certificate of occupancy.
