If your home was built before 1978, lead paint is almost certainly somewhere in it. That is not a reason to panic — it is a reason to be deliberate about who works on your walls, trim, windows, and exterior surfaces. In Massachusetts, the regulatory requirements around lead and renovation are stricter than the federal baseline, and the stakes for getting it wrong range from family health consequences to significant legal liability for the property owner.

This guide is for MetroWest and Milford-area homeowners who want to understand their obligations — and their options — before scheduling any painting, carpentry, remodeling, or window work on a pre-1978 home.

Why Lead Paint Is a Bigger Problem in Massachusetts Than in Most States

An estimated 90 percent of Massachusetts homes were built before 1978, the year the U.S. government banned lead from residential paint, according to MassETI, a Massachusetts-based lead safety training organization. Only 17 percent of those homes have ever been formally inspected for lead.

That statistic has real implications for anyone living in, buying, or renovating in MetroWest towns like Milford, Hopedale, Franklin, Medway, Holliston, Hopkinton, or Bellingham. The housing stock throughout this part of the state is predominantly pre-1978, and much of it predates the mid-twentieth century. Lead was used in house paint in Massachusetts from as far back as the 1690s — a fact documented in the Massachusetts Lead Law notification form published by the Commonwealth — until the federal ban in 1978.

The older the home, the more likely lead paint is present and the higher the concentration tends to be. Intact lead paint on undisturbed surfaces poses minimal ongoing risk. The hazard is created when painted surfaces are scraped, sanded, cut, drilled, or demolished, releasing lead dust and chips into the air and onto surfaces where young children can ingest it. That is the trigger for both health risk and regulatory obligation.

Two Layers of Regulation: The EPA RRP Rule and Massachusetts 454 CMR 22.00

Massachusetts homeowners and contractors must navigate two overlapping sets of lead-safety requirements. Understanding both matters before any renovation project in pre-1978 housing.

The federal EPA Renovation, Repair, and Painting (RRP) Rule took effect April 22, 2010. Under this rule, any contractor paid to disturb painted surfaces in homes, childcare facilities, or schools built before 1978 must be certified in lead-safe work practices, according to the EPA's Lead Renovation, Repair and Painting Program documentation. That includes painters, carpenters, window installers, remodelers, plumbers, electricians — any trade that touches painted surfaces in covered housing. Firms must be certified, and their employees must be trained by a certified renovator.

Massachusetts, however, operates under its own state program. Massachusetts 454 CMR 22.00 — the Commonwealth's lead-safe renovation regulation — was adopted July 9, 2010. The Massachusetts Department of Labor Standards (DLS), not the EPA, administers and enforces lead-safe renovation compliance in Massachusetts, as documented by the National Center for Healthy Housing (NCHH). Massachusetts was specifically authorized by EPA to operate this program in place of the federal standard, and it is stricter in one important respect: under 454 CMR 22.00, a licensed lead-safe renovation supervisor must be present on the job site at all times while renovation work involving painted surfaces is in progress.

Underlying both sets of rules is the Massachusetts Lead Law itself, enacted in 1971 — one of the oldest state lead laws in the country, according to the Trust for America's Health (TFAH). The Lead Law requires that any property built before 1978 where a child under six lives be deleaded. This applies to both rental properties and owner-occupied homes. The obligation is triggered by the occupancy of a young child, not by a child's illness.

Which Projects Trigger the RRP Rule? More Than Most Homeowners Expect

Any paid work that disturbs painted surfaces in a pre-1978 home falls under the RRP requirements. For MetroWest homeowners, the projects that most commonly trigger the rule include:

• Exterior painting: Surface preparation — scraping, sanding, or priming — on a pre-1978 exterior disturbs paint and triggers lead-safe requirements. Our exterior painting projects on older homes require certified practices throughout the prep and application process.
• Interior painting: Any prep work that abrades painted surfaces on pre-1978 interior walls, ceilings, or woodwork triggers the rule. Our interior painting work on pre-1978 homes in MetroWest includes appropriate surface preparation protocols.
• Carpentry and trim work: Removing, sanding, cutting, or replacing painted trim, baseboards, crown molding, window casing, or door frames on a pre-1978 home disturbs painted surfaces. Our carpentry services in MetroWest include lead-safe practices for all pre-1978 millwork and finish work.
• Window replacement: Window removal is one of the highest-risk tasks in pre-1978 homes because decades of friction at the sash and frame have already ground painted surfaces to fine dust. Our window installation services address this with appropriate containment from the start.
• Remodeling: Any remodeling work that removes, modifies, or repaints original surfaces in a pre-1978 structure — from bathroom updates to kitchen renovations — triggers RRP requirements.
• Deck restoration: Painted or stained deck surfaces on pre-1978 structures fall under the rule when prep work disturbs the paint layer. Our deck restoration services use appropriate containment for affected structures.

One exemption worth noting: the RRP Rule generally does not apply to homeowners doing renovation work themselves on their own primary residence. According to the EPA, however, the rule does apply if you rent any portion of your home, operate a childcare facility out of it, or purchase homes to renovate and resell for profit. In Massachusetts, house flippers working on pre-1978 properties are fully covered by the rule.

What Lead-Safe Work Practices Actually Look Like on a Job Site

Certified contractors working under Massachusetts 454 CMR 22.00 approach a pre-1978 project differently from a standard job. The required lead-safe work practices include several non-negotiable elements:

• Containment barriers: Plastic sheeting is used to seal off the work area from adjacent rooms and from the exterior. The goal is preventing lead dust from migrating beyond the immediate work zone.
• HEPA-filtered vacuums: Standard household vacuums cannot capture fine lead particles. Using a non-HEPA vacuum in a lead dust area redistributes the hazard rather than removing it. HEPA filtration is required. This is a warning sign of unqualified work identified by housing law resources including Doubleday Law, which covers Massachusetts lead paint compliance.
• Wet methods: Wet sanding and wet scraping suppress dust generation rather than allowing lead particles to become airborne. Dry abrasion of suspected lead paint is not an acceptable practice.
• Proper waste disposal: Lead-containing debris, sheeting, and materials must be handled and disposed of in accordance with applicable regulations.
• Post-work cleaning verification: Before containment is removed and before residents re-enter, a cleaning check is performed to confirm the work area is clear.
• Mandatory record keeping: Massachusetts requires contractors to document lead-safe practices on every qualifying project, including notification, containment setup, work procedures, and cleanup verification. These records must be maintained and made available.

Pressure washing before an exterior painting project also requires care on pre-1978 surfaces. High-pressure water can disturb deteriorated painted surfaces and generate lead-containing runoff if not executed with appropriate technique and containment. A certified contractor accounts for this in the project scope before the work begins.

Massachusetts Strict Liability: What Property Owners Must Know

The Massachusetts Lead Law contains a strict liability provision that has been in place since the original legislation passed in 1971, according to TFAH's documentation of the Massachusetts lead law framework. This is one of the most significant aspects of Massachusetts law for property owners to understand, particularly for those buying or renovating older homes in towns like Milford and Hopedale.

Under strict liability, if you own a pre-1978 property, fail to delead it, and a child under the age of six living there is lead-poisoned, you are liable for all resulting damages — regardless of whether you knew lead paint was present and regardless of whether you knew a child was living in the property. Strict liability means you do not have to have done anything wrong in the conventional sense for liability to attach. The obligation exists because of the property's age and the child's presence.

For buyers, the timeline is tight: if you purchase a pre-1978 home where a child under six will reside, Massachusetts law requires that the property be deleaded or brought under interim control within 90 days of taking title, according to TFAH. Before selling a pre-1978 property, Massachusetts law also requires full lead-related disclosure to prospective buyers, including any inspection reports, risk assessment reports, and letters of compliance or interim control.

What to Ask Before Hiring a Painting or Carpentry Contractor for a Pre-1978 Home

Not every contractor operating in Massachusetts holds the required Massachusetts lead-safe renovation certification under 454 CMR 22.00. Before hiring anyone for painting, carpentry, window work, or remodeling in a home built before 1978, ask these questions directly:

1. Are you certified under Massachusetts 454 CMR 22.00? Federal EPA RRP certification is not the same as Massachusetts DLS state certification. Ask specifically about the Massachusetts credential.
2. Will a licensed lead-safe renovation supervisor be on site at all times during active work? Massachusetts requires this continuous on-site presence. A vague answer is a red flag.
3. What containment and HEPA vacuum procedures will you use? A qualified contractor should be able to describe the containment plan specifically before the project begins.
4. Will you provide documentation of the lead-safe practices performed? Massachusetts requires record keeping. You should receive written confirmation of what was done on your project.

Frequently Asked Questions: Lead Paint and Renovation in Massachusetts

Does every pre-1978 home in Massachusetts have lead paint?

Not every surface, but the statistical probability is very high. With an estimated 90 percent of Massachusetts homes predating the 1978 lead paint ban, and lead having been used in residential paint in the state since the 1690s, the older your home the more likely lead is present in some form. A formal lead inspection by a licensed lead inspector is the only reliable way to determine which specific surfaces are affected.

Does the RRP Rule apply if I paint or renovate my home myself?

In most cases, no. The EPA's RRP Rule does not apply to homeowners doing renovation work in their own primary residence. However, Massachusetts 454 CMR 22.00 and the Massachusetts Lead Law govern the property itself regardless of who does the work — and the RRP Rule does apply to homeowners who rent any part of their home, operate a childcare facility in it, or buy, renovate, and resell homes for profit.

What is the difference between deleading and lead-safe renovation?

Deleading is the removal or permanent encapsulation of all lead hazards on a property, typically required under the Massachusetts Lead Law when a child under six resides there. Lead-safe renovation (RRP) refers to work practices that minimize lead dust and exposure during a specific renovation, repair, or painting project. Lead-safe renovation does not eliminate existing lead hazards in the home — it ensures the project does not create new exposures or worsen existing ones.

How do I verify that a contractor is lead-certified in Massachusetts?

The Massachusetts Department of Labor Standards (DLS) maintains the registry of licensed lead-safe renovation supervisors and certified firms. Ask any contractor for their Massachusetts DLS certification number and verify it directly with the DLS before work begins. Self-reported certification without verification is not sufficient when lead safety is at stake.
