  • Regulation Revision


    Over the years, regulations have been fluid, with county staff continually drafting revisions to the documents in order to protect the health, safety and welfare of the citizens of Jefferson County. The original zoning resolution was adopted by the county commissioners in 1946 and the land development regulation was adopted in 1978.

    The County is proposing changes to Zoning Resolution, Section 4 and 5, Accessory Dwelling Unit (ADU)

    An Accessory Dwelling Unit (ADU) is an additional dwelling that can either be added to an existing single family detached dwelling, or built as a separate accessory structure on the same lot as the primary dwelling. These types of structures are often called “granny cottages.” To be considered an ADU, the unit has provisions for an independent kitchen, and must be clearly subordinate to the main dwelling.

    Currently, to qualify for an ADU a property owner must prove at a Board of Adjustment hearing that the ADU will only be occupied by a family member, the property is a minimum of one acre, and adequate water and sanitation is provided. All changes proposed are shown in draft 1 of Section 4 and Section 5. Please note that the regulations are being moved from Section 4 to Section 5, so Section 4 will only show deletions. The three major changes proposed are as follows.

    1. Process - The process is proposed to be changed from a Board of Adjustment hearing to an administrative process where the decision is made by staff based on specific criteria. This is why the location of the regulation is changing from Section 4 to Section 5 of the Zoning Resolution.

    2. Occupant - The requirement that the ADU be occupied by a family member is proposed to be removed and replaced by a requirement that one of the units must be occupied by the property owner. The other unit could be occupied by a family member, a caretaker, a nanny, or a renter.

    3. Lot and Unit size - The minimum lot size has been reduced, but the maximum unit size is also reduced on a tiered scale, so that as lot size is reduced so is the size of the ADU.

    Valid proof of water and sanitation will still be required.

    The intent of these regulation changes is not to double the density allowed in an area, or to allow the ADU to be sold off as an independent unit. The intent is to create more housing options for Jefferson County citizens. This would allow some citizens to age in place by having a second unit for perhaps a caretaker or grown children.
