Riverside County Ordinance 348 caps residential floor-area ratio, lot coverage, and height in many residential zones to prevent oversized homes that overshadow neighbors, with stricter rules in scenic and hillside overlays.
Mansionization concerns in Riverside County are addressed through Ordinance 348 zoning standards. Standard residential zones cap floor-area ratio (FAR), lot coverage, and structure height to prevent oversized homes inconsistent with neighborhood character. Hillside Development Ordinance overlays apply additional grading, stepped-foundation, and height-from-grade limits in Lake Mathews, Wine Country, and Idyllwild areas. Scenic Highway corridors near Highway 74 and 243 layer additional design review. Variance applications require findings of hardship; design-review approval may be required for homes exceeding stated FAR. Coachella Valley Specific Plans add their own bulk and massing rules.
Building above FAR or height limits without a variance triggers stop-work orders, after-the-fact permit fees doubled, and potential demolition orders for noncompliant additions.
