Maximum lot coverage in Hemet's single-family residential zones is set by the Development Standards table in Section 90-314A and varies by zone and stories. Higher-density zones (R-1-6, R-1-7.2, R-1-D) allow up to 65% one-story or 45% two-story, while larger-lot zones (R-A, R-1-10, R-1-20, R-1-40) cap coverage at 40%. At least 10% of the remaining area must be landscaped.
Lot coverage in Hemet is governed by the city's zoning code (Chapter 90), specifically the Single-Family Residential Development Standards table in Section 90-314A, and it varies by zone and by whether the structure is one or two stories. In the higher-density zones, maximum lot coverage is 65% for one-story development and 45% for two-story development in the R-1-6, R-1-7.2, and R-1-D zones. In the larger-lot and agricultural zones, R-A, R-1-H, R-1-10, R-1-20, and R-1-40, maximum lot coverage is 40% whether one or two stories. The table also requires that ten percent of the remaining area (the portion of the lot not covered by structures) be devoted to landscaping. Coverage works together with the zone's minimum lot area (for example 5,000 square feet in R-1-D, 6,000 in R-1-6, 7,200 in R-1-7.2, up to 40,000 in R-1-40), minimum lot width and depth, and the required setbacks to determine the buildable footprint. The minimum building area (excluding garage and carport) ranges from 900 square feet in several zones up to 1,600 square feet in R-1-H. Because the maximum coverage percentage depends entirely on your zone and the number of stories, confirm your parcel's zoning classification with the Planning Division (951-765-2375) before designing, and show existing and proposed coverage on your site plan for permit review.
Exceeding the zone's maximum lot coverage is a zoning violation; coverage is reviewed when plans are submitted and can block permit issuance or final approval. Building beyond the allowed footprint, or failing to provide the required landscaping, can require redesign. Enforcement runs through the Hemet Community Development Department, and relief from the standard would require a variance.
