| 12/11/2025 | Residential Zoning | REQUIRES RESUBMIT | PDSD TRANSMITTAL FROM: Roxanne Johnston, Planner PROJECT: TC-RES-1125-05722 3908 S Liberty Av., Tucson, AZ 85706 ADU (1st Review) TRANSMITTAL DATE: 12/11/2025 This site is located within the R-2 Zone (UDC 4.7.9). A single-family residence is a permitted use in this zone (Table 4.8-2) subject to Use Specific Standards 4.9.7.B.6, .9, & .10. RESUBMITTAL OF THE FOLLOWING IS REQUIRED: Please correct plans, as noted in the comments below, along with a response letter indicating how all Site Zoning comments were addressed. 1. Per the City of Tucson Unified Development Code (UDC) Sec. 6.6.3.C, an accessory dwelling unit (ADU) would not be allowed in the front yard of the principal residence: “Detached accessory buildings, including accessory dwelling units, are not permitted in the buildable area extending the full width of the lot between the principal building and the front street lot line…” The path forward may be one of two ways, a). through a Board of Adjustment Variance, or b.) by attaching the ADU to the residence: a. The Board of Adjustment has the authority to approve variances from the UDC, (UDC 3.10.3.A.1). Approval from UDC 6.6.3.C must be obtained through a Board of Adjustment variance before the permit can be approved by Zoning. If the variance route is selected, include the BofA decision letter with the resubmittal packet. To submit an application for a Board of Adjustment Variance requesting that the ADU be located in front of the primary residence, visit www.tucsonaz.gov/Departments/Planning-Development-Services/Planning-Zoning-Applications/Zoning-Administration#section-2 OR, b. By attaching the ADU to the primary residence, there is no need for a variance. 2. The proposed ADU is located within the 5’ perimeter rear and north side setbacks. A Design Development Option is required whether the ADU is attached or not. Please submit a DDO application under the Zoning Modification sub-record that has been created. For instructions on how to apply for a sub record, visit the following link: https://www.tucsonaz.gov/files/sharedassets/public/v/2/pdsd/documents/tdc-faq/new-pdfs/sub-records.pdf For additional questions regarding DDOs, contact Georgia Pennington at georgia.pennington@tucsonaz.gov 3. Per the City of Tucson Inclusive Home Design Ordinance -https://www.tucsonaz.gov/files/sharedassets/public/v/1/city-services/planning-development-services/documents/inclusivehomedesignordinance.pdf , all new dwellings have a requirement to provide an “accessible route from public and common areas, including, but not limited to, a driveway or public street or sidewalk.” Draw, dimension and label an access route from the driveway (or apron), sidewalk, or street to an accessible entrance. Ensure the route meets accessibility standards as articulated in Sections 402-404 of the ADA Accessibility Standards https://www.access-board.gov/ada/chapter/ch04/ . See the Technical Standards Manual (TSM) 7-01.4.3 for specifications, including slope and composition materials – https://codelibrary.amlegal.com/codes/tucson/latest/tucson_az_udc/0-0-0-10261 Please add a comment and show the pathway demonstrating that the ADU will meet ADA per the above codes. 4. The lot coverage is incorrect and reflects the lot coverage for the residence being permitted under TC-RES-0925-04576. Porches are not included in the calculations for lot coverage. By adding the square footage of the new guest house (400) to the primary residence (947) and the driveway area (476), the total lot coverage will be 57%, within the maximum lot coverage allowed in the R-2 zone – 70%. 5. Please be advised that the ADU will not be able to be constructed until the primary residence has been constructed. Additional comments may be forthcoming depending on responses to zoning review comments and plans submitted for the next review.
