| 04/02/2025 | Site Zoning | REQUIRES RESUBMIT | FROM: PDSD Zoning Review PROJECT: TC-RES-1024-06221 1302 S AVENIDA SIRIO – R-1 Casita (ADU) and Carport (2nd Review) TRANSMITTAL DATE: April 2, 2025 Resubmit revised drawings and any redlined plans along with a detailed response letter, which states how all Zoning Review Section comments were addressed. This site is located in the R-1 zone (UDC 4.7.8). A single-family residence (SFR) with an Accessory Dwelling Unit (ADU) is a permitted use in this zone (Table 4.8-2). See Use-Specific Standards 4.9.7.B.6, 8, & 9 and 6.6.3. 1. Provide a residential plot plan that meets the requirements found at: https://www.tucsonaz.gov/Departments/Planning-Development-Services/Building-Safety/Plan-Examples/Plot-Plan-Example, to include but not limited to: a. The lot coverage is not correct. Provide a breakdown as shown the example on the residential plot plan requirements. Provide a lot coverage calculation. b. The property dimensions are not correct. Review the Terra Del Sol final plat found at: https://maps-and-records.tucsonaz.gov/subdivisions/details/1504, and provide the correct dimensions. Provide the property dimensions on the plot plan c. Zoning acknowledges that the required dimensions were provided but the curb line shown should run parallel with the east property line. Provide a dimension from the centerline of AVENIDA SIRIO to the face of curb, where pavement meets the concrete curb, and from face of curb to the north property line. Per Construction Plan I-748K found at: https://maps-and-records.tucsonaz.gov/construction-plans/details/I-748K, the distance from centerline to face of curb is 16’ and from face of curb to property line is 9’. 2. Until the Board of Adjustment is approved Zoning cannot approve this plan. It appears that the proposed carport is not attached to the main dwelling. Per UDC Article 6.6.3.C detached accessory structures over 400 sq. ft are not allowed in the buildable area extending the full width of the lot between the principal building and the front street lot line. A Board of Adjustment for Variance will need to be submitted and approved prior to approval of this plan. Board of Adjustment application/requirements can be found at: https://www.tucsonaz.gov/Departments/Planning-Development-Services/Planning-Zoning-Applications/Zoning-Administration. Contact for the Board of Adjustment is Mark Castro at Mark.Castro@tucsonaz.gov. To avoid the variance process an option would be to attach the carport to the main dwellings with a roof structure that is a minimum of 5’-0” wide and can support a 20 pound live load. 3. Until this comment is addressed Zoning cannot approve this plan. The drawings show the carport overhanging the north property line. An easement will be required to allow this overhang. Show the easement on the plan and provide the recordation information on the plan. Provide a copy of the recorded easement with the next submittal. 4. Per UDC Article 6.6.3.D the maximum height of a detached accessory structure is 12’-0”. Per UDC Article 6.4.4.a the measurement of building height is the vertical distance measured from the design grade elevation to the highest point of a flat roof. The proposed detached carport exceeds the allowed 12’-0” height. A Board of Adjustment for Variance will need to be submitted and approved. 5. The minimum setback is the greater of six (6) feet, or two-thirds (2/3) the height of the structure’s wall facing each interior property line (Table 6.3-2.A). Based on a wall height of 11’-8” the required perimeter yard setback from the proposed detached carport to the north property line is 7’-10”, proposed setback is 0’-0”. A Board of Adjustment for Variance will need to be submitted and approved. 6. There is a 2’-10” dimension from the northeast post of the proposed detached carport to a dimension string. Clarify what this dimension is for. 7. Clearly demonstrate that the requirements of 6.6.3.B.4 are met for the ADU. The Unified Development Code (UDC) can be found at: https://www.tucsonaz.gov/Departments/Planning-Development-Services/Codes/Zoning-Code.
