Title
Conduct a public hearing and consider an ordinance for Zoning Application No. Z0626-0455, submitted by Rita Prieto, for a zoning change from R-3 Single Family Residential to R-3 Single Family Residential with a Conditional Use Permit to allow an Accessory Dwelling Unit (ADU) with modifications to reduce the minimum lot size requirement from 21,780 square feet to 9,780 square feet, increase the maximum allowable area of the ADU from 500 square feet to 756 square feet, and to increase the height of the ADU from 15 feet to 18 feet located at 3501 Antilles Drive.
(No responses in favor or in opposition to the application have been received from property owners within the statutory notification area. The Planning and Zoning Commission recommends approval with certain stipulations.)
Body
The applicant requests a Conditional Use Permit (CUP) to allow an Accessory Dwelling Unit (ADU) on a corner lot at 3501 Antilles in the R-3 Single-Family Residential district. The proposal would replace the existing 572-square-foot detached garage with a new 756-square-foot detached ADU for the applicant’s sister. The proposed structure is located behind the primary residence, meets the applicable setback requirements, complies with the four off-street parking requirements, and will share utility connections with the primary residence.
The applicant requests modifications to three ADU standards: reducing the minimum lot size from 21,780 square feet to 9,780 square feet; increasing the maximum allowable ADU area from 500 square feet to 756 square feet; and increasing the maximum ADU height from 15 feet to 18 feet. The proposed ADU will include 449 square feet of living space in an open-concept studio-style layout with a bathroom and shower, kitchenette, air conditioning, and stacked washer and dryer. The remaining area will include a lofted storage area and a 307-square-foot garage. The proposed ADU will be the same height as the primary residence. All other applicable ADU standards in the Mesquite Zoning Ordinance are met.
On September 14, 2026, the Planning and Zoning Commission voted 7-0 to approve the request subject to certain stipulations.
