The Massachusetts Lead Law and Your Bathroom Renovation

Lead-safe containment on a Massachusetts renovation

Why this matters more here than almost anywhere else

Massachusetts has the oldest housing stock in the United States. A very large share of homes in this state were built before 1978, which is the year lead paint was banned for residential use. That single fact puts most bathroom renovations in Massachusetts under two overlapping sets of rules.

The two rule sets

  • The federal EPA RRP rule. Any contractor disturbing painted surfaces in a pre-1978 home for compensation must be an EPA Lead-Safe Certified Firm and must follow containment, work-practice and cleaning requirements. This applies to essentially every bathroom gut in an older Massachusetts house.
  • The Massachusetts Lead Law. State law goes further, focusing on homes where children under six live. It carries owner obligations around lead hazards and deleading that are stricter than the federal baseline.

What a compliant crew actually does

  1. Tests painted surfaces that will be disturbed, or presumes lead and works accordingly
  2. Seals the work area with plastic sheeting and establishes a controlled entry
  3. Shuts down HVAC to that zone so dust is not distributed through the house
  4. Uses HEPA-filtered vacuums rather than shop vacs, and wet methods rather than dry sanding
  5. Prohibits open-flame burning, power sanding without HEPA attachment and heat guns above 1100 degrees
  6. Performs a verified cleaning at the end and documents it

How to tell whether your contractor is actually doing it

Ask for the firm's EPA certification number and check that plastic goes up on day one. A crew that starts demo in a pre-1978 bathroom with no containment is not cutting corners on paperwork, it is distributing lead dust through a house that people live in.

Ask specifically whether lead-safe practices are included in the quoted price or billed separately. If a quote is dramatically lower than others, this is frequently the reason.

What it means for your schedule

Containment and verified cleaning add time to a project. Not a lot, but it is real, and any contractor telling you a full gut in a 1920s two-family takes the same number of days as one in a 2005 colonial has not accounted for it.

Our position

We are an EPA Lead-Safe Certified Firm and we treat containment as standard practice on every pre-1978 home rather than an upcharge. In this state that is most of the houses we work in, so it is simply how we work.
