How many homes can I build on my property and what size?

The County allows parcels zoned Rural Residential 1:5 (RR 1:5), Rural Residential 1:10 (RR 1:10),an Rural Residential 1:20 (RR 1:20) to have:

  • a house of any size (subject to land use limitations), plus 
  • one (1) Accessory Dwelling Unit (ADU) that's 1,250 square feet or less (including garages and basements).

You can learn more about specific land uses by reviewing the chart in our Unified Development Code (UDC) in section 18.15.040.

If you are planning on purchasing any land and/or a home in Jefferson County, we highly recommend that you speak with a Land Use Planner (using the CAM process), especially if the parcel is on shoreline or on or near any critical areas.
