Most interior and exterior renovations in Riverside require a building permit under California Building Code Section 105.1 and RMC Title 16. Cosmetic work (paint, flooring, cabinet-facing) is exempt. Structural, electrical, plumbing, mechanical, window replacement, and re-roofing generally require permits and trade inspections.
Riverside's Building & Safety Division issues permits under Title 16 of the Municipal Code and the locally adopted California Building, Residential, Electrical, Plumbing, Mechanical, Green Building, and Energy Codes (collectively California Building Standards Code, CCR Title 24). Cosmetic-only work — paint, wallpaper, replacing flooring, replacing cabinet doors, and similar finishes — does not require a permit under CBC 105.2. Nearly every other renovation does: altering walls (load-bearing or not), any new electrical circuit, any new plumbing fixture relocation, HVAC changeout, water heater replacement, window replacement (for egress, Title 24 energy compliance), re-roofing (structural and WUI-ignition-resistant requirements in hillside zones), ADU conversions, garage conversions, and kitchen/bath remodels. Title 24 Part 6 energy compliance typically triggers HERS testing for HVAC and duct changes. Permits can be applied for at the counter at 3900 Main Street or through the online portal. Unpermitted work is a common issue at resale; retroactive permits are possible but may require destructive testing. Code enforcement can issue stop-work orders and penalty fees (typically 2x permit fee).
Specific penalty amounts for this ordinance are not published in a publicly accessible fine schedule. Contact Riverside code enforcement directly for current fines, enforcement procedures, and hearing options.
