FROM: PDSD Zoning Review

PROJECT:
TC-RES-0223-02725
1028 N Contzen Ave - R-3
ADU Unit #1 (3rd Review)

TRANSMITTAL: April 24, 2025

Provided a detail comment response letter with your submittal that clearly shows how you have addressed all comments with your next submittal.

This site is located in the R-3 zone (UDC 4.7.10). A single-family residence (SFR) with an Accessory Dwelling Unit 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. Based on the description provided in the Energov permitting system, “ADU Unit #1” you are proposing an Accessory Dwelling Unit (ADU). Per UDC Table 4.8-2 a single-family residence (SFR) with an Accessory Dwelling Unit is a permitted use in this R-3 zone. Permit TC-RES-0425-01746 for the primary residence will need to be approved and issued prior to approval of this permit.

2. Per UDC Article 6.6.3.C 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. A Board of Adjustment for Variance will need to be submitted and approved for the ADU to be located within the front yard. Zoning recommends that you change the permit description to a single family residence as the R-3 zoned parcel supports 2 single-family residence to eliminate the variance requirement.

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.
