Home inspection

Lead paint in older homes: the federal disclosure and your 10-day window

If the home you want was built before 1978, federal rules give you specific rights before you are bound to buy it. They are easy to waive by accident, so learn them before you write the offer.

EPA notes that although lead-based paint was banned for use in homes in the U.S. in 1978, it is still present in millions of homes. Federal rules therefore require sellers of most housing built before 1978 to share what they know about lead-based paint and hazards, and give buyers a chance to evaluate the home before they are obligated to buy it. Those rules sit alongside your state's own disclosure laws.

What the seller must give you

Under the federal real estate disclosure rule, sellers of pre-1978 housing must disclose known lead-based paint and lead-based paint hazards, provide any available records or reports about them, and give buyers the federal lead hazard information pamphlet. The sales contract includes a lead warning statement and a disclosure form signed by the parties. Real estate agents involved in the sale have duties to make sure this happens.

Read the disclosure form carefully. "No knowledge" is a common answer, and it means only that the seller does not know, not that the home is free of lead.

Your 10-day evaluation window

The regulation at 40 CFR 745.110 says that before a purchaser is obligated under any contract to buy target housing, the seller shall permit the purchaser a 10-day period to conduct a risk assessment or inspection for lead-based paint or lead-based paint hazards. Two details change how it works in practice:

  • The parties can mutually agree in writing to a different period.
  • The buyer may waive the opportunity entirely by indicating so in writing.

Offer forms usually include a lead section where you choose to keep the 10 days, agree to another period or waive it. Do not tick the waiver box by default.

Inspection or risk assessment?

A lead inspection identifies whether lead-based paint is present and where. A risk assessment looks for current hazards, such as deteriorating paint or lead dust, and suggests ways to control them. For a buyer deciding whether to proceed and how much repairs might cost, a risk assessment often answers the more practical question. Use certified professionals, and ask what the report will include and how soon you will receive it, so the results arrive inside your window.

The calculator below counts days from your start date. Check the contract to confirm when the window starts and whether it counts calendar or business days.

If hazards are found

EPA explains that lead-based paint is usually not a hazard if it is in good condition, but that deteriorating paint is a hazard that needs prompt attention. Options include asking the seller to correct hazards before closing, negotiating a credit or price reduction, or, if your contract allows, cancelling. Correcting hazards should be done with lead-safe work practices; renovation, repair and painting work on pre-1978 homes by contractors is subject to EPA's lead-safe certification rules.

Think about your plans too. If you intend to renovate, sand or replace windows, lead affects how that work must be done and what it costs.

Loans and appraisals

FHA appraisals on homes built before 1978 look for defective paint, and lenders may require repair before closing. That can affect as-is sales. If you are using FHA, ask your lender early how a peeling-paint finding would be handled.

Keep the paperwork

Keep the signed disclosure, the pamphlet acknowledgment and any lead reports with your closing documents. They are part of your record of the home's history, and they help if you sell or renovate later.

Lead checklist for a pre-1978 home

  • Confirm the year the home was built from public records or the listing.
  • Read the seller's lead disclosure form and any reports they provide.
  • Decide whether to use the 10-day evaluation window, and do not waive it by default.
  • Book a certified lead inspector or risk assessor early in the window.
  • Get repair estimates for any hazards before the deadline.
  • Plan how you will handle renovation safely after closing.

Questions buyers ask

Does the lead rule apply to every home built before 1978?

The federal real estate disclosure rule applies to most housing built before 1978, which the regulation calls target housing. There are exceptions, so ask your agent if the home is in an unusual category.

Is lead paint always dangerous?

EPA explains that lead-based paint is usually not a hazard if it is in good condition. Deteriorating paint that is peeling, chipping, chalking, cracking or damaged is a hazard and needs prompt attention.

Can I waive the lead inspection?

Yes. The regulation allows the buyer to waive the opportunity in writing. Waiving it in a competitive market can make an offer more attractive, but you give up a federally protected chance to evaluate the home.

Does my home inspector test for lead?

Usually not. A general home inspection is visual and typically excludes lead testing. A lead inspection or risk assessment is done separately by a certified professional.
