The City of Tucson is proposing a change to the zoning code to make it easier to build casitas in Tucson. This proposal was initiated by Mayor and Council in November 2020 and has been developed based on input from the public and a stakeholder group.
Casitas, also known as Accessory Dwelling Units, are independent living spaces with their own kitchen. They provide more flexible housing options, support aging in place, and are a way of promoting sustainable infill development.
Currently, these types of units are restricted to either a guest house without a kitchen, or are considered a second dwelling unit and can only be built on large lots. This proposal would make it easier to build casitas across the city.
The proposal to allow Accessory Dwelling Units (ADUs) in Tucson has been developed based on input from the public and a stakeholder group and is currently going through public review.
The current draft proposal would allow:
- One ADU to be built on any residential lot in the city (meaning a lot with one or two homes)
- The maximum size of the ADU would be 1,000 square feet for lots over 7,000 square feet and 750 square feet on lots under 7,000 square feet
- All other dimensional standards, including maximum building height, lot coverage, and setbacks would apply
- One parking space would be required per ADU, which could be waived for sites that are a quarter-mile from transit or a bike boulevard; on-street parking can also be used
- Each newly constructed ADU would be required to have a cool roof
The Planning Commission will hold a virtual Public Hearing on this proposal on Wednesday, September 15 at 6pm. You can submit written comments or request to speak at the continued hearing on September 15, 2021, by emailing PlanningCommission@tucsonaz.gov.
