Contra Costa County, CA Rental Property Rules: Lead Paint Disclosure (2026)

Unincorporated Contra Costa County follows federal Title X (Residential Lead-Based Paint Hazard Reduction Act of 1992) and California Health & Safety Code Sections 17920.10 and 105250 et seq. for lead paint disclosure obligations. Any rental dwelling built before 1978 requires landlords to provide tenants with the EPA-approved pamphlet 'Protect Your Family From Lead in Your Home,' a Lead Warning Statement, and disclosure of any known lead-based paint or hazards before the tenant becomes contractually obligated. The Contra Costa Health Services Lead Poisoning Prevention Project enforces abatement orders for lead hazards identified through child blood-lead screening. Deteriorated paint in pre-1978 units is presumed to be lead-containing unless testing proves otherwise. Violations carry penalties up to $10,000 per unit under federal law plus state nuisance abatement remedies.
