Homes built before 1978 in Los Angeles may contain lead-based paint. Federal law (EPA RRP Rule) requires lead-safe work practices for any renovation disturbing more than 6 sqft of painted surface in pre-1978 homes.
Lead paint was banned in 1978. Homes painted before that date likely have lead paint under newer layers. When disturbed (sanding, scraping, demolition), lead dust becomes airborne. Lead exposure causes: brain damage in children (even at low levels), nervous system damage, kidney problems, and reproductive issues. LA has a higher percentage of pre-1978 homes than most US cities.
XRF testing (handheld scanner): $200-$400 for whole-house scan. Results in minutes. Most accurate. Paint chip lab testing: $25-$50 per sample, sent to lab, results in 5-7 days. DIY swab kits ($10-$20): screening only — positive results need lab confirmation. Test BEFORE starting any renovation in a pre-1978 home.
The Renovation, Repair, and Painting (RRP) Rule requires: EPA-certified renovators perform the work, containment of the work area with plastic sheeting, HEPA vacuuming of all dust, wet methods for dust suppression, and post-work cleaning verification. Fines for non-compliance: up to $37,500 per day per violation. NP Line Design is EPA Lead-Safe Certified.
Abatement: complete removal of lead paint ($8-$15/sqft). Required for: severely deteriorated paint, high-risk surfaces (window sills children can access), and when specified by health department. Encapsulation: coating lead paint with a specialized sealant ($3-$6/sqft). Acceptable when: paint is intact, surface won't be disturbed, and ongoing monitoring is feasible.
Contain: seal work area with 6-mil plastic, turn off HVAC to prevent dust spread. Minimize: use wet methods (misting before scraping), chemical strippers instead of sanding, HEPA-equipped power tools. Clean: HEPA vacuum all surfaces, wet-wipe with lead-specific cleaner, clearance testing before removing containment. Protect: workers wear P100 respirators and disposable coveralls.
