402 S Jerrie Av, Unit 2, Tucson, AZ 85747
ADU (2nd Review)

TRANSMITTAL DATE: 12/31/2025

This site is located within the R-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.

RESUBMITTAL OF THE FOLLOWING IS REQUIRED: Correct plans, as noted in the comments below, along with a response letter indicating how all Site Zoning comments were addressed.

The site plan on Sheet AS1.0 is missing some of the information required for a full Site Zoning review. The requirements can be found at: https://www.tucsonaz.gov/Departments/Planning-Development-Services/Permits/Plan-Examples/Plot-Plan-Example Below is a list of requirements specific to your project.

1. Please show the zoning of the surrounding properties.
2. Provide the lot dimensions on Sheet AS1.0. This information can be found at the Pima County Assessor’s website, here: www.asr.pima.gov/ParcelData/Map/Arm/MP09/09040_03.PDF
3. Show the vehicle use area for the principal residence
4. Show the distance from the main residence to the front and side property lines.
5. Keynote 2 on Sheet AS1.0 indicates a setback line just north of the ADU. This is an incorrect line; the 5’ setback line for the ADU runs parallel to the property line and is then 10’ where it intersects with the 20’ front property line.
6. Per the Paving Plan for Jerrie Ave., https://maps-and-records.tucsonaz.gov/construction-plans/details/I-62-014_02 , (I-62-014_002) Provide the measurement from the centerline of Jerrie Ave to the front property line (30’).
