Lead-safe renovation rules explained for California homeowners

If your home was built before 1978, your contractor has extra rules to follow when disturbing paint.

Short answer

The EPA's Renovation, Repair and Painting (RRP) rule requires contractors who disturb painted surfaces in pre-1978 homes, child-care facilities and schools to be EPA-certified and follow lead-safe practices such as containment, limited dust-producing methods and careful cleanup. Homeowners should ask for the contractor's certification before work begins.

Key takeaways

  • The rule applies to pre-1978 homes and child-occupied facilities.
  • Contractors must be certified and follow lead-safe practices.
  • Ask for the certification before signing a contract.
  • Asbestos is a separate check — test suspect materials too.

What the rule covers

The rule applies to paid renovation, repair and painting work that disturbs painted surfaces in pre-1978 housing and child-occupied facilities. Small jobs may fall under minor-repair exceptions, but window replacement and demolition generally do not.

What lead-safe work looks like

A certified contractor will usually:

  • Seal off the work area with plastic sheeting
  • Avoid open-flame burning and high-speed sanding without dust controls
  • Use wet methods to keep dust down
  • Clean with HEPA vacuums and wet wiping
  • Give you the EPA Renovate Right pamphlet before work starts

Questions to ask your contractor

Ask whether the firm is EPA-certified, who the certified renovator on site will be, how dust will be contained, and how the area will be cleaned and checked afterward.

Then ask whether the materials being removed have been tested for asbestos. Lead and asbestos rules are separate, and one does not cover the other. American Heritage Environmental only tests for asbestos. We do not test for mold or lead, and we never sell or perform removal of any kind.

    Bathroom remodel cleared

    Old sheet vinyl and backer board both sampled. The report cited the exact layers so the tile crew knew what to do.

FAQ

Lead-safe renovation rules: common questions

Does the rule apply if I do the work myself?

The rule applies to paid contractors, but the EPA strongly recommends homeowners use the same lead-safe practices.

Does lead-safe work also handle asbestos?

No. Asbestos has separate rules. Test suspect materials for asbestos before demolition.

Glossary

Asbestos terms your contractor and lab report will use

ACM
Asbestos-containing material — any material with more than 1% asbestos by weight.
PACM
Presumed asbestos-containing material — older suspect material treated as positive until testing proves otherwise.
Friable
Material that can be crumbled by hand pressure and therefore releases fibers easily.
Non-friable
Asbestos locked in a hard matrix such as floor tile or stucco; hazardous mainly when cut or broken.
PLM
Polarized Light Microscopy, the standard laboratory method for identifying asbestos in bulk building samples.
Point count
A more precise PLM technique used when asbestos content is near the 1% regulatory threshold.
Homogeneous area
A group of material that is uniform in color, texture and installation date — each one needs its own sample.
Chain of custody
The signed record tracking a sample from collection to laboratory analysis.
Chrysotile
White asbestos, by far the most common type found in most states residential materials.
Amosite
Brown asbestos, typically found in insulation board and thermal products.
Encapsulation
Sealing or covering asbestos material in place instead of removing it — often the cheapest compliant option.
Abatement
Licensed removal of asbestos material under containment, performed by a certified abatement contractor.
