| 05/20/2026 | Residential Zoning | REQUIRES RESUBMIT | PDSD TRANSMITTAL FROM: Jeffrey W. Cassidy, Planner Planning & Development Services Department – Current Zoning Review Section PROJECT: TC-RES-0526-02499 – Residential Building – Unpermitted ADU/Sleeping Quarters 4473 E PIMA ST Unit 3 TUCSON, AZ 85712 (R-2 Zoning) Plan Review – 1st Review TRANSMITTAL DATE: May 20, 2026 This site is in the R-2 Residence Zone (UDC 4.7.9). A single-family residence (SFR) and accessory dwelling unit (ADU) are permitted uses in this zone (Table 4.8-2) subject to Use Specific Standards 4.9.7.B.6, .9, & .10 for the SFR and 4.9.7.B.6, 8, & 9 and 6.6.3 for the ADU. The City's Unified Development Code (UDC) (Section 1.4.1.C) establishes that before the City issues any approvals or permits; we must confirm that a site complies with UDC standards. Therefore, as part of permit reviews, we review a site's permit history and compare it to aerial photography to confirm that unpermitted work has not occurred. In many cases, this does mean that a homeowner must apply for permits for unpermitted work before we can approve any new work on that site. Plan review for the above referenced ADU/sleeping quarters has been completed. This letter reflects comments to be addressed. For facilitating a shorter back check time, please provide updated plans and calculations with a written response to each of the notated items indicating action taken. Do not cloud the changes made for comment updates; revisions are processed if changes occur after the permit is issued. 1. COMMENT: Clarify if the intent of the scope of work is to be an Accessory Dwelling Unit or Sleeping Quarters. The difference lies within whether not there is a ‘full kitchen’ defined as having a standard refrigerator (versus under counter half size) and whether or not a permanent stovetop will be included. While zoning did not see a stove, the language matters as this affects impact fees being assessed and landscaping requirements. 2. COMMENT: The site plan provided is incomplete. Specifically: A. Draw and label 5’-0” setbacks off the north and west property lines. B. Draw and label 20’-0” front yard setback off of south property line. C. Draw and label 10’-0” side yard setback off of east property line. D. Draw, label and dimension all vehicular use area(s) (parking, driveway, backup areas) and include in lot coverage table: All enclosed structures plus all vehicular use areas divided by total lot size equals lot coverage percentage number. E. The scale noted does not match the plan graphics on the site. Update the graphics to match the scale noted or vice-versa. 3. COMMENT: Per UDC 6.6.3.C. standard, 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 front street lot line, except for shade structures or carports not over 400 square feet in floor area, terraces and steps not over three high above the natural grade, paved areas, and fences or walls. The existing 199 square foot shed does not meet this standard. A couple of options exist: A. Remove Shed. B. Relocate shed to the side or back of the principal residence. C. Leave the design presented and attempt to secure relief from this standard through the Board of Adjustment Variance process. See below for more information on the B/A Variance process. Zoning cannot approve this permit until the Board of Adjustment (B/A) Variance Process is completed and approved. See below for more information on the B/A Variance process. 4. COMMENT: The street side yard setback along the east property line is 10’-0” and the 81 square foot unpermitted shed is in that setback. A couple of options exist: A. Remove Shed. B. Relocate shed to the side or back of the principal residence. C. Leave the design presented and attempt to secure relief from this standard through the Design Development Option (DDO) process. See below for more information on the DDO process. 5. COMMENT: After reviewing the property documentation history in Property Research Online (PRO), zoning could not verify any permit documentation for the following. A. The 81 square foot shed along the east property line built around 2023 approximately. B. ‘Animal shade’ structure that was installed around 2016 approximately. Zoning will not be able to approve the permit application until the permit information is provided. If permit documentation cannot be provided, all structures less than 200 square feet (sf) can be included in this permit. A separate permit will be required if size exceeds 200 sf and/or has utilities serving it. Acknowledge the inclusion of these unpermitted structures in this permit in the comment response letter. 6. COMMENT: Additional comments may be forthcoming on the next review based on responses to Zoning and other PDSD reviewer comments.
