11/22/2022 Site Zoning REQUIRES RESUBMIT ZONING REVIEW TRANSMITTAL

FROM: Wyatt Berger
Planner

PROJECT: TC-RES-1122-00406
1532 E 9th St – R-2
2nd dwelling (1st Review)

TRANSMITTAL DATE: November 22, 2022

COMMENTS: The following comments are relative to an application for a Design Development Option (UDC Section 3.11.1).

Please resubmit revised drawings and any redlined plans along with a detailed response letter, which states how all Zoning Review Section comments were addressed.

1. Clarify whether the covered structure in the rear of the detached garage is being demolished. As the structure appears in aerial photography as early as 1958, historic approval to demolish the structure is required.

Buildings, portions of buildings, or structures that are 50 years of age or older must be architecturally documented prior to demolition. Documentation will be reviewed and approved by the Historic Preservation Office before a permit is issued.

Demolition (Historic and Older Structures) Application and General Information may be downloaded (PDF) at https://www.tucsonaz.gov/files/pdsd/Preservation/Historic_Demolition_Application_Form.pdf. Submit the completed application as “Additional/Supporting Documentation” for this permit number.

2. As you are proposing a building with a full-service kitchen, change the name of the structure from “guest house” to “second dwelling” on the plans.

3. Provide a floor plan of the existing residence. Per UDC Table 7.4.4-1, two on-site motor vehicle parking spaces are required for the proposed two-bedroom dwelling. Show the location of these parking spaces on the site plan. If five or more total parking spaces are required for the entire site, the commercial parking requirements of UDC 7.4.6 and 7.6.4 apply.

4. The required side and rear perimeter yard setbacks are 6’-0”, or 2/3 the height of the building wall, whichever is greater (UDC Table 6.3-2.A). Based on a wall height of approximately 12’-8”, measured from design grade (the ground) to the highest point of the building wall, the required side perimeter yard setback to the east and south lot lines is 8’-4”; proposed is 6’-0”.

Based on a wall height under 9’-0”, the required rear perimeter yard setback measured from the posts of the rear covered entry to the south lot line is 6’-0”; proposed is 2’-0”. Design Development Option (DDO) approval is required to reduce the side and rear perimeter yard setbacks.

The DDO application and requirements can be found at: https://www.tucsonaz.gov/files/pdsd/forms/2019_DDO_for_Setback_and_Height_UDC.pdf. The DDO application shall be submitted as “Additional/Supporting Documentation” under this existing activity number. Contact Mark Castro at Mark.Castro@tucsonaz.gov should you have questions regarding the DDO process.
