Do not cloud the changes made for comment updates; revisions are processed if changes occur after the permit is issued.

SCOPE OF REVIEW:

The scope of this plan review covers architectural, plumbing, mechanical, energy conservation and electrical. All code references are to the 2018 International Residential Code and 2018 International Energy Conservation Code. All features were checked only to the extent allowed by the submittals provided. All portions of this project are assumed to meet or will meet other departmental requirements, conditions, and concerns before permit approval.

07/02/2025 Site Zoning - Standard REQUIRES RESUBMIT FROM: PDSD Zoning Review Section

PROJECT: TC-RES-0625-02870
4207 E WAVERLY ST. – R-1
Convert Detached Garage into ADU (1st Review)

TRANSMITTAL DATE: July 2, 2025

COMMENTS: Provide a detailed response letter with your submittal that clearly shows how you have addressed all Zoning comments.

This site is located in the R-1 zone (UDC 4.7.8). A single-family residence (SFR) is a permitted use in this zone (Table 4.8-2). See Use-Specific Standards 4.9.7.B.5 - 9.

1. Provide a residential plot plan that meets the requirements found at: https://www.tucsonaz.gov/Departments/Planning-Development-Services/Permits/Plan-Examples/Plot-Plan-Example, to include but not limited to:
a. Provide a lot coverage calculation that meets the requirements of UDC Article 6.4.3 and the example shown on the Residential Plot Plan Requirements.
b. Show all utility lines on the plot plan.
c. Indicate the zoning of the parcel and all adjacent parcels on the plot plan.
d. Provide perimeter yard setback dimensions from the proposed ADU to the east property line.
e. Per the New Sierra Vista final plat there is a 5’ utility easement that runs along the north and west property line. So these easements on the plot plan.

2. The layout of the existing residence shown on the plot plan does not match what is shown on current aerial photos, i.e. there is what appears to be a structure attached to the northwest corner of the house that is not on the 2023 aerials.

3. Per UDC Article 6.6.3.B.6 the minimum side and rear yard setback for an accessory dwelling unit is five feet. As a perimeter yard setback from the ADU to the east property line was not provided Zoning cannot determine what process will be needed to reduce the required setback. If the setback is less than 1’-0” a Board of Adjustment for Variance is required. If the setback is 1’-0” or greater but less than 5’-0” a Design Development Option is required.

4. Clearly demonstrate that the requirements of UDC Article 6.6.3.B.5 are met.
