Sedona, AZ Building Setbacks & Zoning: Lot Coverage Limits (2026)

Every zoning district's lot and building standards table sets two separate impervious coverage caps: a building coverage maximum covering only the footprint of principal and accessory structures, and a higher total coverage maximum that adds in everything else that sheds water. In the RS-70 Large Lot Single-Family Residential district, building coverage is capped at 15 percent of the lot and total coverage at 30 percent; other districts carry their own numbers in the same table format, keyed to the same definitions.

Section 2.24.F(1) defines what counts toward total impervious coverage in every district: principal buildings; accessory buildings, parking garages, carports, and utility and storage sheds; porches, stairways, elevated walkways, and any paved or otherwise water-impervious surface; and parking areas and driveways regardless of surfacing material, unless the Director approves an alternative pervious paving system. Section 2.24.F(2) narrows the building coverage calculation to just the principal building and the accessory structures listed above, leaving driveways and patios out of that smaller number. Section 2.24.F(3) flags that adding impervious surface can trigger additional drainage requirements under Section 5.3, Grading and Drainage, since more hardscape means more stormwater runoff has to be retained or detained on site rather than left to sheet across the lot.
