Mayor and Council Public Hearing on Accessory Dwelling Units October 19

A proposal to allow casitas, or Accessory Dwelling Units (ADUs), in Tucson was recommended for approval by the Planning Commission. Mayor and Council will hold a virtual Public Hearing on October 19 before they consider adopting this code amendment. Email to submit comments or request to speak at the virtual hearing. 

Casitas, or ADUs, 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. The proposal to allow casitas in Tucson was developed based on input from the public and a stakeholder group over the past 10 months.

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 current 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
