Lead Dust Cleanup Rules After Renovating a Pre-1978 Home

If your US home was built before 1978 and a paid contractor disturbs painted surfaces, the EPA Renovation, Repair and Painting (RRP) rule requires that contractor to clean the work area in a set way and then prove it with a cleaning verification wipe test before the containment comes down. That cleanup is the renovator's legal job, not something a homeowner can waive, and it is separate from the general post-renovation cleaning most houses still need afterwards.

Below: what the rule covers, how cleanup and verification work, and where a follow-up clean fits.

Who the RRP rule applies to

The rule sits in the federal regulations at 40 CFR Part 745, Subpart E. It covers work done for compensation in "target housing" (most homes built before 1978) and in child-occupied facilities such as daycares in older buildings. Landlords, property managers, general contractors, painters, plumbers, electricians and window installers all fall under it when the job disturbs paint.

The trigger is the size of the disturbance:

• More than 6 square feet of painted surface per room inside the home
• More than 20 square feet of painted surface on the exterior
• Any window replacement, regardless of size
• Any demolition of painted surfaces, regardless of size

Small jobs under those thresholds are exempt, unless they use prohibited methods. Open-flame burning, power sanding or grinding without HEPA shroud attachments, and heat guns above 1,100°F are not allowed on regulated work at all.

The firm has to hold EPA Lead-Safe Certified Firm status, and a certified renovator has to be assigned to the job. Some states, including Massachusetts, Washington, Oregon and Wisconsin, run their own EPA-authorized programs with their own licences, so the certificate you see may come from a state agency instead of EPA. Before work starts, the firm must give you the "Renovate Right" pamphlet and get your signature acknowledging it.

One exemption matters for budgeting: a homeowner doing work on their own owner-occupied home is not covered. The rule targets paid work. Lead dust behaves the same way either way, though, so a DIY project in an older house deserves the same care.

What the required cleanup involves

The rule spells out the cleanup sequence once the dusty work is finished. Inside the home, the certified firm's crew has to:

1. Collect all paint chips and debris, then mist the protective sheeting, fold it dirty side inward and seal it in heavy bags.
2. HEPA-vacuum every surface in the work area, starting high and working down: walls, windowsills, window troughs, counters, floors.
3. Wipe walls (either HEPA-vacuum and then wet-wipe, or wet-wipe directly) and wipe all other horizontal surfaces with a damp cloth.
4. Mop uncarpeted floors with a two-bucket method or a wet mop system that keeps the rinse water separate from the dirty water.
5. HEPA-vacuum carpets with a beater bar, slowly, in overlapping passes.

A regular shop vacuum does not count. The rule requires a vacuum with a HEPA filter, built so that air cannot bypass the filter, which is the same standard serious post-renovation cleaners use for fine drywall and sanding dust.

The cleaning verification wipe test

After the cleanup, the certified renovator (not an assistant) checks the work against the EPA cleaning verification card, a laminated card with a printed reference shade.

• Each windowsill in the work area is wiped with a wet disposable cleaning cloth and the cloth is compared to the card.
• Uncarpeted floors and countertops are wiped in sections of no more than 40 square feet each, with a fresh cloth per section.
• If the cloth matches or is lighter than the card, that surface passes.
• If it is darker, the surface is cleaned again and re-wiped with a new cloth.
• If it fails a second time, the crew waits one hour or until the surface is dry, then wipes it with an electrostatic dry cloth. That surface is then considered clean.

Only after every surface passes can the warning signs and containment come down. For exterior jobs the rule requires a visual inspection for dust, debris and residue instead of the wipe test.

Some contracts, landlords, lenders or local laws ask for dust clearance testing instead of the card method. In that case a certified inspector, risk assessor or dust sampling technician takes wipe samples that go to an accredited lab. In 2024, EPA lowered the dust-lead levels used to clear lead abatement work to 5 micrograms per square foot on floors, 40 on windowsills and 100 on window troughs, so expect clearance testing to be stricter than it was a few years ago. Lab results take a few days, which can push back your move-back date.

Records you can ask for

The firm must keep records showing how it complied, including the certified renovator's checklist and the cleaning verification results, for three years after the job. You are entitled to a copy of that documentation once the work is complete. It is worth asking for it in the contract and keeping it with your house papers, since it helps if you sell or rent the home later.

If a contractor says the cleanup is "included" but cannot tell you who the certified renovator is or when verification will happen, treat that as a warning sign. EPA's online lookup lets you search for certified firms by name or location.

Canadian homes

Canada has no federal equivalent of the RRP rule for private renovations. Health Canada advises that homes built before 1960 likely contain lead paint, and that homes built up to about 1990 may still have some. Its guidance for renovations mirrors the US approach: contain the work area, avoid dry sanding and heat guns, HEPA-vacuum, and wet-wipe. Provincial occupational health rules apply to the workers, and in Quebec and Ontario that means site rules on dust exposure for crews, but there is no mandated wipe test for the homeowner's benefit. Asking for one in the contract is reasonable.

Where a post-renovation clean fits

Passing the verification card means the work area is below the rule's threshold for lead dust. It does not mean the house is ready to live in. Several things usually remain:

• Fine non-lead dust from drywall, tile cutting and new flooring that travelled outside the containment
• Dust inside HVAC registers, return grilles and the first few feet of ductwork
• Tops of door frames, light fixtures, ceiling fans, baseboards and the insides of cabinets and drawers
• Rooms the crew never cleaned because they were outside the regulated work area

A separate post-renovation clean picks up that wider area with HEPA-filtered vacuums and several passes. Schedule it after the renovator has finished cleanup and verification (and after any lab clearance results come back), never as a substitute for them. If you want the cleaners to treat a room the contractor already verified, tell them, so they use damp methods there too and nothing gets dry-swept. Our guide to what contractors usually leave behind covers that list room by room.

Frequently asked questions

Can a homeowner waive the lead-safe cleanup requirements?

No. EPA removed the old opt-out provision in 2010, so a homeowner cannot sign away lead-safe work practices or cleaning verification for a regulated job in a pre-1978 home. The certified firm has to follow the full process no matter who lives there.

Does the RRP rule apply to DIY renovations?

Work you do yourself on your own owner-occupied home is not covered by the federal rule. If you hire anyone for pay, including a handyman for one part of the project, that paid work is covered once it crosses the size thresholds. The same cleanup steps are still the safest approach for DIY work in an older house.

How long after lead-safe cleanup can a family move back in?

Once every surface passes the cleaning verification card, the regulated work area can be reopened the same day. If your contract or local law requires lab clearance testing, plan for a few extra days for results. Many families also wait until a follow-up whole-home clean is done, especially with young children in the house.

Is cleaning verification the same as a lead clearance test?

No. Cleaning verification is a visual comparison against EPA's reference card, done on site by the certified renovator. Clearance testing sends wipe samples to an accredited lab and gives a measured number in micrograms per square foot. Clearance is required after lead abatement and sometimes by contract or local law, while verification is the default for ordinary renovation work.
