| 10/21/2025 | Residential Zoning | REQUIRES RESUBMIT | PDSD TRANSMITTAL FROM: Roxanne Johnston Planner PROJECT: TC-RES-0925-04476 4446 E Linden St., Tucson, AZ 85712 Second Residential Unit (1st. Review) TRANSMITTAL DATE: 10/21/2025 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. Lot coverage is calculated based on the square footage of enclosed structures and vehicle use areas, whether improved or not including driveways, carports, garages, and areas used for parking or standing. Porches are not included. Please recalculate and revise the site plan, (Sheet 1). 2. For the purposes of meeting the perimeter setback requirements, Table 6.3-2A of the Unified Development Code (UDC) provides that the perimeter setbacks for the R-2 zone are 20’ in the front and 6’ to the rear and sides OR 2/3 the height of the proposed exterior wall, whichever is greater. UDC 6.4.4A defines the building height as the ‘vertical distance measured from the design grade elevation to the highest point of a flat roof to the deck line of a mansard roof; or to the middle (between the eve and ridge) of the highest gable of a pitched or hipped roof...’ Top of Window is not used, nor is Finished Floor Elevation. The current building heights listed on the site plan (Sheet 1), and taken from the elevation sheet (Sheet 6) are 14’-1” are based on the maximum building height, which would put the setbacks beyond 9’ if used. Please use the building height measurements from the UDC listed above and provide the correct building elevations to both the site plan and elevation sheet so staff can ensure the correct setbacks have been met. For questions regarding Zoning comments, please contact me at: Roxanne.Johnston@tucsonaz.gov |
