What Can you Build in seattle?

This feasibility calculator helps homeowners and small developers understand:

  • How many units may be allowed under NR zoning

  • Approximate buildable area under the new FAR limits

  • Early cost implications tied to unit count and configuration

Results are conceptual and intended to support early decision-making—not replace a site-specific zoning analysis.

Seattle’s Neighborhood Residential (NR) rezone significantly expands what can be built on formerly single-family lots—allowing stacked flats, higher FAR, and 4–6 units on most properties. This calculator provides an early look at what the new rules could mean for your site.
