05/16/2024 Site Zoning REQUIRES RESUBMIT ZONING REVIEW TRANSMITTAL

FROM: Wyatt Berger
Lead Planner

PROJECT: TC-RES-1123-09350
422 North Belvedere Avenue – R-1
Accessory Dwelling Unit (2nd Review)

TRANSMITTAL DATE: May 16, 2024

Please resubmit revised drawings with a detailed response letter stating how all Zoning Review Section comments were addressed.

1. This comment has not yet been addressed. A Secondary Dwelling Unit is not a use defined in the Unified Development Code. As the lot size is under 10,000 square feet, the proposed dwelling unit must be considered an accessory dwelling unit (ADU).

2. Provide a notation indicating the accessory dwelling unit will be developed with a high albedo level (>60 SRI) or other cool roof technology per the ICC Green Construction Code (UDC 6.6.3.B.3).

3. Per UDC 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. Show the required structural attachment(s) connecting the existing principal building and the proposed accessory dwelling unit. Per a previous Zoning Administrator’s determination, the structures may be considered attached if a structural element at least five feet wide with a live load of at least 20 pounds is provided.

4. Per UDC 6.6.1.C, the proposed accessory use shall not substantially alter the exterior appearance or character of the principal use or building to which it is incidental. As discussed previously, provide a narrative demonstrating how the proposal does not substantially alter the appearance or character of the existing residence.

5. Per UDC 6.4.5.C.1.a, the required front street perimeter yard is 20 feet as measured from the street property line. The proposed front street perimeter yard is 8’-3” as measured from the west lot line. Site Zoning acknowledges a Design Development Option (DDO) application has been submitted to reduce the above requirement.

6. Per UDC 6.4.5.C.1.b, the required side street perimeter yard is 10 feet as measured from the street property line. The proposed side street perimeter yard is 6’-10” as measured from the north lot line. Site Zoning acknowledges a Design Development Option (DDO) application has been submitted to reduce the above requirement.
