| Residential Zoning * | REVIEW COMPLETED | PDSD TRANSMITTAL FROM: Roxanne Johnston Planner PROJECT: TC-PRE-0326-00060 522 E Helen St., Tucson, AZ 85705 ADUs (Preapplication Conference) TRANSMITTAL DATE: 04/16/2026 This site is located within the NR-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. Please note that the following site zoning comments are only preliminary as the plans may change based on information obtained through this pre-application process, the Neighborhood Preservation Design Review, and future review by Site Zoning staff of the permit materials submitted. 1. As the applicant is aware, the property lies within the Feldman’s Neighborhood Preservation Zone. A NPZ review (UDC 5.10.3) must be approved prior to Site Zoning approval of the construction permit. The applicant has applied for a Neighborhood Preservation Zoning review. The letter of approval by the NPZ design committee is required to be submitted with the site plan and construction documents. 2. The request for the predevelopment conference is for two accessory dwelling units. Only the rear proposed structure can be an ADU, and that is with modifications. Per the Unified Development Code (UDC) 6.6.3.B.5, an ADU may only contain up to 75% of the square footage of the principal dwelling. The size of the proposed ADU located on the southern portion of the lot may only contain up to 820.5 sq ft. providing that the updated Unit 1 (primary residence) contains 1,094 sq ft as shown on Sheet A.1. It may be useful to note that 2 ADUs are allowed on the lot providing there is one existing primary residence. Assuming Unit 1 is the primary residence containing 1,094 sq ft, both ADUs may contain up to 820.5 sq. ft each. Additionally, neither ADU would require parking provisions. 3. Please include all zoning-related information directly on the site plan (Sheet A.01). For a list of required site plan information please refer to the ‘Full’ site plan instructions at https://www.tucsonaz.gov/Departments/Planning-Development-Services/Permits/Plan-Examples/Site-Plan-Examples A few examples of items missing from or incorrect on the site plan shown on Sheet A.01 include the following: a. Property zoning. (NR-1) zoning and zoning overlay (Feldman’s Neighborhood Preservation Zone). b. The legal description on Sheet A.01. c. Provide a basic project description. Aerial Pictometry from Pima County shows an existing residence with a front porch. In reviewing the plans, another unit (attached) is planned in the rear connected with a breezeway attached to the residence to the north. This needs to be clear. d. Distance between structures. 4. Recalculate Lot Coverage on Sheet A.01. Porches and breezeways do not count towards lot coverage – only enclosed structures and vehicle use areas such as those that appear to measure approximately 3,448 sq. ft. This brings the lot coverage percentage down to from 60.2% to 46% (3,448 sf/7,500 sf = 0.4597), yet this figure will likely shrink due to the rear ADU needing a reduced square footage. 5. Submit a landscape plan on the revised site plan. City of Tucson Ordinance No. 12219 was effective as of January 1, 2026. This ordinance is an amendment to the Unified Development Code. UDC Article 7, Section 7.6.10 and requires landscaping for all new single family residential, middle housing development, and accessory dwellings. It is not necessary to hire a landscape architect. The landscape plan is to be applied directly onto the site plan. Here is a link that breaks down the landscape requirements and provides additional clarification: https://middle-housing-cotgis.hub.arcgis.com/pages/Residential-Landscaping-Code . The link to Ord. No. 12219 is shared below. 6. Engineering will provide their comments on the requirement for a 4’-wide pathway leading from the ADU. 7. Please note that the ADU in the rear will be assessed impact fees. Should the applicant not wish to be assessed impact fees, by eliminating the stove, full sized refrigerator and double kitchen sink, the unit is then a ‘sleeping quarters’ by definition. In this instance, an undercounter fridge and single basin sink is allowed. 8. Additional comments may be forthcoming depending on responses to zoning review comments and plans submitted for the next review. The City of Tucson Unified Development Code may be accessed at this site: https://codelibrary.amlegal.com/codes/tucson/latest/tucson_az_udc/0-0-0-1 Recent amendments to the UDC may be found here: https://www.tucsonaz.gov/files/sharedassets/public/v/1/pdsd/documents/middle-housing/middle-housing-ordinance-clean.pdf For questions regarding Zoning comments, please contact me at: roxanne.johnston@tucsonaz.gov |
