Removing a wall in a
pre-1978 LA home.

The rule, in plain terms

Federal law requires that contractors assume every surface in a home built before 1978 contains lead-based paint, unless it's been specifically tested by a state-certified lead inspector. Under the EPA's Renovation, Repair and Painting (RRP) Rule, any work that disturbs more than 6 square feet of interior painted surface — or 20 square feet on the exterior — triggers the rule. Removing a wall almost always clears that threshold.

What the rule actually requires

At least one EPA Lead-Safe Certified Renovator has to be present at the job site for the duration of the work. That person earns certification through a one-day course from an EPA-accredited training provider — it's not automatic, and it's not the same as a general contractor's license. On top of the individual certification, the contracting firm itself has to be registered with the EPA as a Lead-Safe Certified Firm, which applies even to sole proprietors.

Why this isn't optional paperwork

Lead-safe work practices exist because uncontrolled demolition of lead-painted surfaces creates lead dust, and that dust is genuinely dangerous — especially for children and pregnant women in the home during construction. The RRP rule requires specific containment, cleanup, and verification steps precisely to prevent that. This isn't a box-checking exercise; it's the difference between a contained, cleaned worksite and one that leaves lead dust in your home's air and surfaces for months after we've left.

What to actually check before you hire

Ask directly: is your firm EPA Lead-Safe Certified, and who on the crew holds individual RRP Renovator certification? A contractor who can't answer that immediately, for a pre-1978 home, is a real red flag — not a minor oversight. California doesn't layer additional state requirements on top of the federal rule, so EPA certification is the actual, complete standard here; there's no separate state certification to also ask about.

What this means for your project

If your home was built before 1978 and your scope includes removing or significantly disturbing a wall, we factor lead-safe containment and cleanup into the plan and the price from the start — not as a change order once demo has already begun. It adds a real but modest amount of time and cost, and it's non-negotiable on our jobs regardless of what a homeowner is willing to waive, because the exposure risk doesn't go away just because it's inconvenient.
