2017-077 Accessory Dwelling Unit Date: October 27,2017 Report No. 2017-077 INFORMAL STAFF REPORT TO MAYOR AND CITY COUNCIL SUBJECT: Review of Denton Development Code for Backyard Cottages/Accessory Dwelling Units in the City of Denton. EXECUTIVE SUMMARY: Accessory dwelling units have become a viable option for affordable housing in recent years. Following is an examination of how the city regulates accessory dwelling units, where in the city they are permitted, and a chart of how other cities in the Metroplex regulate them. BACKGROUND: Denton Code 2030 The Land Use Section of the Denton Plan 2030, briefly references accessory dwelling units in Goal LU-3, Grow out Assets: Maintain and Strengthen Neighborhoods, Commercial and Employment Areas. Specifically it states that when reviewing appropriate types of residential infill development that would be compatible within single family neighborhoods, "...accessory dwelling units such as garage apartments and"granny flats" and a second small unit on a single family lot could be considered." (Denton Plan 2030,pg. 42-43) Denton Development Code Regulations Permissions by Zoning District Following are tables for each zoning district indicating those districts in which accessory dwelling units are Permitted(P), require approval of a Specific Use Permit(SUP), are Not Permitted(N), and have limitations on them [L(1)]. This information can be found in §35.5 of the Denton Development Code (DDC). L(1)=Accessory dwelling units are permitted, subject to the following additional criteria: 1. The proposal must conform to the overall maximum lot coverage and setback requirements of the underlying zone. 2• The maximum number of accessory dwelling units shall not exceed 1 per lot. 3. The maximum gross habitable floor area(GHFA) of the accessory residential structure shall not exceed 50% of the GHFA of the primary residence on the lot, and shall not exceed 1000 sq. ft. GHFA unless the lot meets the requirements of L(1).5. 4. One additional parking space shall be provided that conforms to the off-street parking provisions of this Chapter. 5. The maximum gross habitable floor area(GHFA) of the accessory residential structure shall not exceed 50% of the GHFA of the primary residence on the lot, where the lot size is equal to or greater than ten acres in size. An SUP is not required for such an accessory residential structure where the lot size is equal to or greater than ten acres. 1 Date: October 27, 2017 Report No. 2017-077 Rural Districts RD-5 RC Accessory Dwelling Units P P Neighborhood NR-1 NR-2 NR-3 NR-4 NR-6 NRMU- NRMU Residential Districts 12 Accessory Dwelling SUP SUP SUP SUP SUP L(1) N Units L(1) L(1) L(1) L(1) L(1) Downtown University DR-1 DR-2 DC-N DC-G Core Districts Accessory Dwelling P P N N Units Community Mixed Use CM-G CM-E Districts Accessory Dwelling N N Units 2 Date: October 27, 2017 Report No. 2017-077 Regional Mixed Use RCR-1 RCR-2 RCC-N RCC-D Districts Accessory Dwelling N N N N Units Employment Centers EC-C EC-E Accessory Dwelling N N Units Industrial Centers IC-E IC-G Accessory Dwelling N N Units Please refer to the attached map for locations and information regarding Planned Developments (PDs) and Master Planned Communities (MPCs).

Historic Districts The historic districts within the city typically may have had a carriage house or even garage that has been converted. Specifically, it is believed that many historic properties have dwellings on them that were once carriage houses or storage. There are also a few garage apartments located in the historic districts. If directed, staff could conduct research,which would include interviewing property owners to determine the number of such dwelling units in the districts. Accessory Dwelling Units: Best Practices Staff researched how other cities regulated Accessory Dwelling Units. Following is a table summarizing our findings. A more detailed summary of each city's regulations can be found attached to this report.
