Do I Need a Permit? (Exemptions)

Overview

Not every project needs a permit. Use this page to check your project. For each project type you’ll see plan requirements, key notes, and the permit type(s) needed if a permit is required.

Read carefully to follow local rules. See the Frequently Asked Questions.

† The granting of a City permit does not exempt the applicant from complying with any HOA Covenants, Conditions, and Restrictions (CC&Rs) or other private deed restrictions associated with the property; and permit issuance is not an indication that the work complies with any HOA’s CC&Rs or private deed restrictions.

If you are in a Historic Preservation Zone (HPZ) or are a Historic Landmark (HL), all development requires a permit and Historic Preservation Design Review.

If your project requires a permit, visit the self-service online permitting portal Tucson Development Center Online, or visit the TDC Online Instructions page for more information before applying.
