Community residential development standards
Enter hypothetical lot dimensions to see what would be allowed under the CR zone — density, setbacks, building footprint, and development coverage per TMC 18.10.040.
Results are illustrative only and assume a regularly shaped lot with no encumbrances. They do not account for irregularly shaped parcels, critical areas, shoreline jurisdiction, easements, or other site-specific constraints. Always confirm requirements with DCD staff before submitting a permit application.

Subdivision feasibility and fire access
Use this tool to explore how a parent parcel in the CR zone could be subdivided into new lots. Each new lot must meet the 5,000 sf minimum. Once you know how many lots are possible, use the CR Development Standards tool above to see what can be built on each one — including how many dwelling units are allowed per lot based on its size.
For example: a parent parcel that yields 3 conforming lots of 5,000 sf each would allow up to 3 dwelling units per lot under standard CR density rules, for a total potential of 9 units on the site.
