Why Building Safety: Lead Paint Rules (2026)

Federal law governs lead paint in Pima County, as Arizona has not adopted a more restrictive state program. The EPA Renovation, Repair, and Painting (RRP) Rule (40 CFR Part 745) requires that renovations disturbing more than 6 square feet of interior painted surfaces or 20 square feet of exterior painted surfaces in pre-1978 housing be performed by EPA-certified renovation firms using lead-safe work practices. Arizona Department of Health Services (ADHS) maintains a lead poisoning prevention program and tracks elevated blood lead levels in children. Federal disclosure requirements under 42 USC 4852d mandate that sellers and landlords of pre-1978 housing provide the EPA pamphlet Protect Your Family From Lead in Your Home, disclose known lead hazards, and allow 10-day inspection periods for buyers. Pima County has older housing stock in areas like Tucson foothills, Three Points, and historic mining communities where lead paint is more prevalent. Demolition of pre-1978 structures in unincorporated Pima County must address lead paint as part of the Pima County Development Services demolition permit process. Child-occupied facilities (schools, daycares) in pre-1978 buildings are subject to enhanced federal requirements.
