Why the age of a home matters: lead-based paint
Federal law treats housing built before 1978 as likely to contain lead-based paint.
Before a lease or sale of most pre-1978 housing, the landlord or seller must disclose any known lead-based paint and hazards and give the tenant or buyer the EPA pamphlet (42 U.S.C. § 4852d; 40 CFR part 745, subpart F; 24 CFR part 35, subpart A).
A contractor paid to renovate, repair or paint a pre-1978 home must be a certified firm, use a certified renovator and follow lead-safe work practices under the Renovation, Repair and Painting Rule (40 CFR part 745, subpart E) whenever the job disturbs more than 6 square feet of painted surface in a room or more than 20 square feet outside; window replacement and demolition always count (40 CFR 745.83).
Certification comes from EPA, or from the state where EPA has authorized the state to run the program.
The Census Bureau groups construction by decade, so the share built before 1978 lies between the share built before 1970 (18.9%) and the share built before 1980 (46.3%).
