Home My WebLink About2.0 Text Amendments Memo ADUGarfield County MEMO TO:Planning Commission FROM:Patrick Waller, Senior Planner DATE:August 22,2l0g RE:Updates to ADU requirements :BACKGROUND Pursuant to the Land Use and Development Code of 2OL3, applicants may apply for an Accessory Dwelling Unit (ADU) - Land Use Change Permit. All ADU applications are subject to an Administrative Review process. ln recent years, staff has seen a substantial increase in the amount of ADU applications. The chart below shows the number of ADU applications received since 20L0.

They allow for possible rental housing options for citizens of the County and also permit property owners to earn extra incomc through the use of the unit as both short-term and long-term rentals. Through the increased number of ADU applications, staff has noticed an opportunity to increase efficiency in the review that would provide a benefit for customers of the Community Development Department and the citizens of the County. RECOMMENDED CHANGES & CORRECTIONS Staff has provided a list of code sections that will make the ADU process more efficient for smaller units. The biggest change is to add a new use to Table 3-403, titled "Dwelling Unit, Secondary". This use will require an Administrative Review and will still be required to meet current ADU requirements. The definition of "Dwelling Unit, Accessory" will be updated to limit the overall size to 1000 square feet. This use will be permitted by-right in all zone districts. Broadly, the changes are as follows: The following pages describe the proposed changes in detail Prop osed Dwelling Unit Amendments Lot Size Additional Dwelling Unit Options Review Process Minimum Lot Size for Zone District ADU permitted by-right up to 1"000 square feet Building Permit Double Minimum Lot Size for Zone District ADU permitted by-right up to 1000 square feet or Secondary Dwelling Unit up to L,500 square feet Building Permit Administrative Land Use Change & Building Permit 4 Acres or Greater ADU permitted by-right up to 1000 square feet or Secondary Dwelling Unit up to 3,000 square feet Building Permit Administrative Land Use Change & Building Permit 2lPage P ed Land Use an D lo ment Code Amendments ARTICLE 3 Existing Proposed Page 3-22 Table 3-403 Dwelling Unit, Accessory Requires Administrative Review Permitted by-right Page 3-22 Table 3-403 Dwelling Unit, Secondary Use is not listed Create use category - Requires Administrative Review Subject to 7-70L requirements ARTICLE 5 EXISTING PROPOSED Page 5-2 s-102 (F)Exemptions from Subdivision Exempts ADU's and 2-Family Dwelling Units from Subdivision lnclude Secondary Dwelling Unit ín this category ARTICLE 7 EXISTING PROPOSED PageT-2O 7-302 (M)Backing Onto Public Streets Prohibited Current definition includes single- family and duplex, but does not include Accessory Dwelling Unit or Secondary Dwelling Unit lnclude Secondary Dwelling Unit,2-unit dwelling units and Accessory Dwelling Unit Page 7-2O 7-303 Landscaping Standards Single-Family Dwelling Units, Accessory Dwelling Units, lndustrial Uses and all uses located fully within a parcel of land in an lndustrial Zone District are exempt from this section.
