Perris, CA Building Setbacks & Zoning: Lot Coverage Limits (2026)

Perris controls building bulk through maximum lot coverage standards set within each single-family residential district under Title 19. In the R-7,200 zone (Section 19.24.080(f)) and the R-6,000 zone (Section 19.25.080(f)), the maximum lot coverage is 60 percent for one-story dwellings and 40 percent for two-story dwellings — meaning a taller home is allowed to cover less of the lot, preserving open space and yard area as buildings grow vertically. Lot coverage works alongside the district's minimum lot size (7,200 and 6,000 square feet respectively), the 20-foot front and rear setbacks, the 5-foot-per-story side yards, and the 30-foot height cap to define the buildable envelope. The city records zoning, lot size, and lot coverage on its building site-plan form, confirming that coverage is checked at permit review. Because these percentages and lot minimums change from zone to zone — larger-lot districts (R-10,000, R-20,000) have their own standards — the applicable coverage figure depends on your property's exact zoning. California state law does not set a citywide lot-coverage cap, so these are City of Perris standards. Verify your lot's coverage limit and how accessory structures and patios count toward it with Development Services before designing an addition or new home.
