Lead paint was banned in 1978, but it didn't disappear — it's still on the walls, trim, and siding of about 60% of homes in Hudson, Marlborough, Worcester, and the surrounding MetroWest market. Here's what federal law requires and what Hudson-area homeowners need to verify before any paint job starts.

What is the EPA RRP rule?

The federal Renovation, Repair and Painting (RRP) rule (40 CFR Part 745) requires any contractor doing work that disturbs more than 6 sqft interior or 20 sqft exterior of painted surfaces in a pre-1978 home to be EPA Lead-Safe certified. This applies to painting, drywall repair, window replacement, siding work, demolition, and renovation.

Violations carry civil penalties up to $40,000+ per day. The rule applies to contractors, but the homeowner is the one who lives in the dust if it's not done right.

Why this matters in Hudson and MetroWest

About 60% of homes in Hudson (built 1750s–present, with peak construction in the 1900s–1970s), Marlborough, Worcester, Framingham, Natick, and the surrounding MetroWest market are pre-1978. Most original layers of paint contain lead.

Lead dust is the primary health hazard, not intact paint. The dust gets created when paint is sanded, scraped, or chipped — exactly what happens during prep for a new paint job. A 50-microgram speck of lead dust on a windowsill exceeds the federal hazard threshold.

What an EPA Lead-Safe job actually looks like

If your home is pre-1978, the contractor must:

  1. Verify EPA Firm Certification — the company itself must be certified, not just the workers. Verify at the EPA Firm Locator.
  2. Use a Certified Renovator on site at all times during disturbance.
  3. Hand you the EPA pamphlet "Renovate Right" before starting.
  4. Contain the work area — plastic sheeting on floors, walls, doorways. Interior work requires 6-foot perimeter; exterior requires 10-foot ground containment.
  5. Use HEPA tools — HEPA vacuum, HEPA-filtered sanders, no dry scraping with open-air sanders.
  6. Prohibit certain practices — no open-flame burning, no high-temp heat guns above 1100°F, no power sanding without HEPA, no power-washing with high-pressure on exterior lead paint.
  7. Daily cleanup — HEPA vacuum the work area and 2 feet around it before crew leaves each day.
  8. Final cleaning verification — wet-wash all hard surfaces with a wet cloth, then a clean cloth, then verify cleanliness with a white cloth wipe.
  9. Provide records — keep training records and project documentation for 3 years.

How to verify a Hudson-area contractor is EPA certified

  1. Ask for the EPA Firm Certification number. It's a 7-digit number like NAT-12345-1.
  2. Go to the EPA Firm Locator and search by firm name or state.
  3. Confirm the listing shows "Active" certification status and the firm address matches.
  4. Ask which Certified Renovator will be on your job. That person's name should be on the contract.

If the contractor can't produce the EPA number or hesitates, walk away. The certification costs them ~$300 and 8 hours of training — there's no excuse not to have it if they work pre-1978 homes.

What about your own DIY work?

The RRP rule applies to paid contractors, not homeowners working on their own property. You can legally sand your own pre-1978 walls. But the lead-dust health hazard is the same — and the cleanup is just as hard. If you're disturbing significant paint, follow the same containment + HEPA procedures.

Pregnant women, children under 6, and pets should be out of the home during DIY lead-paint disturbance. Period.

Lead paint testing — do you need it?

The RRP rule allows contractors to assume lead is present in pre-1978 homes and apply full safe-work practices. That's the default and most cost-effective approach.

Alternatively, the contractor can test individual surfaces with EPA-recognized test kits (LeadCheck, D-Lead). If a surface tests negative, RRP requirements lift for that surface.

For a typical Hudson kitchen-bath-trim job, testing rarely saves money. For a focused single-room job in a 1970s home where lead is unlikely, testing can be worth $200–$400 to skip the full RRP scope.

What it costs in Hudson MA

EPA RRP compliance typically adds $300–$900 to a residential interior paint job and $500–$1,500 to a typical exterior. The cost reflects:

  • Containment materials (plastic, tape, dust barriers)
  • HEPA vacuum and HEPA-filtered sander rental/wear
  • Certified Renovator labor premium (~10% over standard rate)
  • Disposal of contaminated debris (must go to landfill in sealed bags)
  • Final cleaning verification

Compared to the $5,000–$25,000+ in fines for non-compliance and the health risks to your family, the added cost is non-negotiable.

Bottom line for pre-1978 Hudson homeowners

  • Assume your home has lead paint if built before 1978.
  • Hire only EPA Lead-Safe certified contractors — verify the firm number, not just the claim.
  • Expect $300–$1,500 added cost for RRP compliance on a typical paint job.
  • Keep children, pets, and pregnant women out of the work area during disturbance.
  • Don't accept "we'll just be careful" — that's not RRP compliance, that's negligence.
