Massachusetts Lead Paint Law: Exterior Deleading, Costs, and Penalties

Under the Massachusetts lead paint law, exterior requirements apply to any residential property built before 1978 where a child under six lives, and they cover siding, porches, window casings, trim, and railings along with the soil directly below them. Peeling exterior paint must be removed or contained by a certified abatement contractor, and the work has to be documented by a licensed inspector or risk assessor before you have legal protection. The rules do not wait for a complaint, a blood test, or a tenant to raise the issue. They trigger the moment a young child occupies the property.

When the Exterior Rules Kick In

The Massachusetts Lead Law, at M.G.L. c. 111, §§ 189A–199B, applies to pre-1978 residential property where a child under six years old lives. It does not matter whether you own or rent the property, whether the child has tested positive for elevated blood lead levels, or whether anyone has filed a complaint. The obligation triggers automatically based on the building’s age and the child’s age.¹

Covered properties include rental units, owner-occupied single-family homes, and child-occupied facilities such as daycares and preschools. A “child-occupied facility” is a pre-1978 building that a child under six visits at least two days per week for at least three hours per visit, with annual visits totaling 60 hours or more.²

Coverage runs to all accessible surfaces, inside and out. Handling interior hazards while ignoring the exterior does not put you in compliance.

Which Exterior Surfaces Are Covered

Exterior lead paint on pre-1978 homes often contains higher lead concentrations than interior coatings, and when it deteriorates the chips and dust fall directly into the soil where children play. That pathway is why the statute pulls outdoor surfaces in on equal footing with interior ones.

Surfaces a licensed inspector will evaluate outside the home include:

Clapboard and other siding.
Porches, porch railings, and porch decking.
Exterior window casings, sills, and window assemblies.
Door frames and exterior doors.
Decorative trim and other accessible painted components.

Bare soil near the foundation or along drip lines gets evaluated too. If exterior paint has been shedding into the ground below it, the soil is part of the hazard, and covering or replacing the paint without addressing the soil leaves the problem in place.

Containment materials used outdoors have to meet the weather-resistance and durability standards in the Department of Public Health regulations at 105 CMR 460. Approved outdoor coverings need to hold up against rain, freeze-thaw cycles, and UV exposure. A product that passes on an interior wall will not necessarily be accepted on siding or a porch column.

Two Paths to Compliance

Massachusetts gives owners two ways to satisfy the law. Both apply to exterior work, and they carry different timelines and different levels of legal protection.

Full Deleading

Full deleading permanently removes or covers all lead paint on the property, exterior included. A licensed lead inspector evaluates the home, a certified abatement contractor performs the work, and a licensed inspector reinspects. Passing that reinspection produces a Letter of Full Compliance.³

A Letter of Full Compliance is the strongest legal protection available. Once it is in place, an occupant or former occupant cannot bring a strict-liability claim against you under Section 199. You still owe a duty of reasonable care to keep the property in its compliant condition, but the automatic exposure is gone.⁴

Interim Control

Interim control is a faster, less expensive route that addresses urgent hazards without fully deleading. A licensed risk assessor identifies the most pressing dangers and prepares an emergency lead management plan. If the property meets interim control standards after the work is done, the risk assessor issues a Letter of Interim Control, valid for one year and renewable once for a second year.⁵

The hard cap is two years total. By the end of that window, full deleading has to be complete if a child under six still lives in the property, even if the property changes hands during that time.⁵

While a Letter of Interim Control is in effect, Section 199 strict liability is off the table, but you have to maintain the conditions the letter and the emergency plan require. Fall short of that duty of care and you are liable for resulting damages.⁴

Who Can Do Exterior Work

Only certified lead abatement contractors may perform the actual deleading. On the outside of a home this typically means stripping or encapsulating siding, scraping and recoating trim, and sometimes replacing porch railings or window assemblies outright. A licensed inspector reinspects when the work is complete before any compliance letter issues.

Federal law adds a second layer on any exterior renovation that disturbs paint. The EPA’s Renovation, Repair, and Painting Rule requires that the contracting firm be certified and that individual renovators be trained in lead-safe work practices. Scraping and repainting siding, replacing exterior windows, and repairing porch decking on a pre-1978 home all fall inside the rule. Massachusetts operates its own EPA-authorized RRP program, so certification runs through the Massachusetts Division of Occupational Safety.⁶

Federal civil penalties for RRP violations can reach $49,772 per day for penalties assessed on or after January 8, 2025.⁷ Hiring an uncertified painter for exterior work on a pre-1978 house is a fast way to invite federal enforcement on top of state exposure.

Massachusetts trains, licenses, and monitors private-sector inspectors through the Childhood Lead Poisoning Prevention Program, which oversees roughly 8,000 inspections a year.¹ You can verify a license through the department’s registry. Work performed by an unlicensed inspector or uncertified contractor does not produce a valid compliance letter, no matter how thorough it looks.

Costs and the State Tax Credit

Costs vary with the size of the home, the number of affected surfaces, and whether you remove paint or encapsulate it. Full deleading of a typical single-family home in Massachusetts often runs $8,000 to $20,000 or more. Smaller projects targeting a single room or specific exterior trim can run $2,000 to $5,000. Post-abatement clearance inspections that use dust-wipe sampling to confirm lead levels typically add a few hundred dollars.

Massachusetts offers a state income tax credit that offsets some of the expense:

Full deleading: a credit equal to the lesser of the actual deleading cost or $1,500 per dwelling unit.
Interim control: a credit equal to the lesser of half the interim control cost or $500 per dwelling unit.

To claim it, you have to be the owner, have paid the costs, and hold either a Letter of Full Compliance from a licensed inspector or a Letter of Interim Control from a licensed risk assessor.⁸ The credit is a dollar-for-dollar reduction of state tax rather than a deduction, and it applies per unit, so it scales with the size of a multi-family building.

What Skipping Exterior Compliance Costs You

Section 199 imposes strict liability on any owner who fails to comply. If a child under six develops lead poisoning while living in a non-compliant property, the family does not have to prove negligence or knowledge. They only have to show that the child’s blood lead level meets the state’s definition of lead poisoning and that you were out of compliance.⁹ The Massachusetts Supreme Judicial Court held in Bencosme v. Kokoras that neither negligence nor knowledge of the risk is an element of liability under this section.¹⁰

If you receive notice of dangerous lead levels and willfully fail to take the required corrective action by the applicable deadlines, damages are trebled. Actual damages for a seriously lead-poisoned child can reach six or seven figures once medical costs, developmental harm, and long-term care are added up, and tripling that number can be financially catastrophic.⁹

Section 196 sets separate criminal penalties for applying lead-based paint to any surface of a dwelling, interior or exterior. Fines run $100 to $500 per violation, with each surface counted separately, and willful violations carry up to three months of imprisonment per violation.¹¹

Insurance is unlikely to catch you if a claim comes. Standard commercial general liability policies treat lead as a pollutant and exclude coverage for lead-related bodily injury. In Massachusetts, the Property Insurance Underwriting Association attaches a Lead Poisoning Exclusion endorsement (DL 24 41) to policies insuring pre-1978 residential rental units with dwelling personal liability coverage. A limited buy-back endorsement (DL 24 42) may restore some coverage with sub-limits, and a narrow exception may apply if you recently acquired the property (typically within 90 days of taking title) and are actively complying with the Lead Law’s new-owner provisions. Outside that window, the largest liability the property carries is generally uninsured.

You Cannot Push the Cost onto Tenants

The compliance burden stays with the owner. A landlord cannot refuse to rent because lead paint is present, refuse to rent to families with children under six to avoid deleading, charge a tenant for deleading costs, or use a lease clause to limit the landlord’s obligation or liability. Any such clause is unenforceable.¹²

Tenants also have anti-retaliation protection under M.G.L. c. 186, § 18. A landlord who retaliates against a tenant for reporting a lead paint problem risks additional legal exposure on top of Lead Law liability.
