Parcel: 121-08-3280
Zoning: R-1
Existing Use: Single Family Residence
Project Description: Accessory Dwelling Unit

TRANSMITTAL DATE: 8/18/2023

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


1. COMMENT: Provide a Vehicular Use Area calculation on Sheet 1 and add it to the Lot Coverage Calculation.

2. COMMENT: Per UDC Article 4.9.7.B.7, in the R-1 zone, “For every bedroom over five, one additional space is required for each bedroom. For all single-family dwellings in the R-1 zone with five or more bedrooms, and for all lots containing two or more single-family dwellings, with the second dwelling having more than one bedroom, all parking spaces must be located on-site, either in a side or rear perimeter yard.”

Provide a floor plan of the existing SFR on the site to determine the amount of parking required. Demonstrate on the site plan how the above parking requirement is being satisfied.

3. COMMENT: Per UDC Article 11.4.20, a Site is defined as, “The land area consisting of a portion of a lot, an entire lot, or contiguous lots, designated for development as a single entity.”

The proposed addition would create a third dwelling unit on the site. Per UDC Article 11.3.7.A.3, Multifamily Development is considered any residential development consisting of three or more dwelling units on an integrated site or single lot.
