| 09/16/2026 | Residential Zoning | REQUIRES RESUBMIT | PDSD TRANSMITTAL FROM: Erick Bieber Planning & Development Services Department – Zoning Review Section PROJECT: TC-RES-0926-04982 – Residential Building 2416 E Drachman St, Tucson, AZ 85719 Residential Addition/Alteration Permit (1st Review) TRANSMITTAL DATE: September 16th, 2026 This site is located in the R-1 zone (UDC 4.7.8). A single-family residence is a permitted use in this zone (Table 4.8-2) subject to Use Specific Standards 4.9.7.B.5 -.9 & .12. RESUBMITTAL OF THE FOLLOWING IS REQUIRED: Correct plans, as noted in the comments below, along with a response letter indicating how all Site Zoning comments were addressed. 1. (Comment) The existing structure does not appear to feature a kitchen. The addition of a kitchen to a habitable accessory structure triggers the Accessory Dwelling Unit (ADU) classification. The conversion from a habitable accessory structure into an ADU requires an ADU new dwelling permit rather than a Residential Addition/Alteration permit. The Unified Development Code (UDC) can be found at: https://www.tucsonaz.gov/Departments/Planning-Development-Services/Codes/Zoning-Code For questions regarding Zoning comments, please contact me at: Erick.Bieber@tucsonaz.gov |
