Which Properties Fall Under Pre-1978 Lead Paint Laws

Pre-1978 rental property lead laws apply to most residential buildings constructed before January 1, 1978, the date the federal government banned lead-based paint in housing, and this guide covers what those rules require.

The date matters because lead was a standard paint ingredient for decades. Any unit built before the ban may still contain lead-based paint under layers of newer coatings, and that paint becomes a hazard when it chips, peels, or turns to dust.

The 1978 Cutoff and Why It Matters

The 1978 cutoff is the dividing line for the federal disclosure framework. A property built before that year is presumed to carry some risk; a property built after it generally falls outside that framework.

That presumption does not mean every older building has a hazard. It means the burden shifts: you must disclose what you know, and in many jurisdictions prove the unit is lead-safe before renting it.

Exemptions and Edge Cases Landlords Should Know

Federal disclosure rules carry narrow exemptions, and the boundaries of those exemptions depend on the facts of each property. When a property may straddle an exemption, consult the official EPA guidance and document your reasoning in writing before you sign a lease.

Federal Lead-Based Paint Disclosure for Tenants

Federal lead-based paint disclosure for tenants is a paperwork obligation, not a testing mandate. Under the federal lead disclosure framework, landlords of pre-1978 housing must disclose known lead hazards and give tenants the EPA pamphlet before a lease begins (the EPA). The EPA lead disclosure rule overview spells out the requirement in full.

The distinction trips up many owners: federal law requires disclosure of known hazards rather than an inspection of every unit. Testing becomes decisive when renovation triggers the EPA Renovation, Repair and Painting Rule, which governs paid work that disturbs paint in pre-1978 housing.

Here is the disclosure workflow we walk landlords through:

1. Disclose any known lead-based paint or lead hazard in the unit
2. Provide the EPA pamphlet "Protect Your Family From Lead in Your Home"
3. Include the lead warning statement in the lease
4. Collect the tenant's signed acknowledgment
5. Retain disclosure records for at least three years

Our guide to handling lead paint disclosure for tenants walks through each step. Skipping the acknowledgment is the most common failure we see, and it is the easiest to fix.

Philadelphia Rental Lead Requirements and Local Enforcement

Philadelphia rental lead requirements go further than federal disclosure. The city ties rental licensing to lead-safe certification for pre-1978 units, which means a landlord here must do more than hand over a pamphlet.

The practical consequence: in Philadelphia, "I disclosed it" is not the same as "I complied." Federal Title X disclosure and local lead-safe certification are two separate obligations that run on two separate clocks. A landlord can satisfy the EPA pamphlet and acknowledgment requirement and still fail a city license review because no lead-safe certificate is on file.

How the Local Requirement Differs From Federal Disclosure

The cleanest way to keep the two straight is to separate what each rule actually demands:

The distinction between federal disclosure and local certification is one that is easy to blur. Federal disclosure requires handing over a pamphlet; the local requirement continues until a certified inspector has tested the unit and the certificate is filed.

What the Certificate Actually Documents

A Lead-Safe Certificate in Philadelphia is documentation that a pre-1978 unit has been tested for lead hazards. Because the certificate is tied to a specific unit and a specific test date, a landlord with multiple pre-1978 units should confirm the certification requirement for each one.

Norristown and Other Municipal Processes

Owners in Norristown should confirm the current local requirement with the municipality before renewing, since local processes vary.

Watch out: a certificate from one municipality should not be assumed to satisfy another's requirements.

For the full statutory picture, see our Philadelphia rental property lead laws guide. If you are unsure which local process applies to a specific address, contact our team before the renewal deadline rather than after.

Lead Dust Wipe Testing: What It Measures and When You Need It

Lead dust wipe testing measures lead residue on surfaces where children crawl and play: windowsills, floors, and window wells. A technician wipes a measured area, and an EPA-approved lab reports the lead loading per surface.

You need dust wipe testing when a child under six lives in or visits a pre-1978 unit, after any renovation that disturbs paint, and when a local certificate depends on lab results. Our lead dust wipe test guide explains sampling in detail.

Getting a Lead-Safe Certificate in Philadelphia

A Lead-Safe Certificate in Philadelphia is issued after a certified inspector tests the unit and finds no lead hazards above the applicable standard. The certificate documents that a pre-1978 rental is safe to lease, and it is what local enforcement looks for at license renewal.

The process runs in a predictable order:

1. Schedule an inspection with a certified firm
2. Have dust wipe samples collected and sent to an EPA-approved lab
3. Receive results, typically within days
4. Address any failing surfaces and retest
5. File the certificate with your rental license

99leadsafe.com offers lead-safe inspection services, and current pricing is available on our website. Expedited service is available when a lease signing is close. Our guide to getting Lead-Safe Certification covers the filing steps.

What to Do After a Lead Hazard Is Identified

A failed test is not a crisis; it is a to-do list. Disclosure obligations are only part of the picture. When a dust wipe comes back above the standard, a landlord needs a sequence of steps, not only a legal summary. Here is a workflow for responding to a failed result, in order.

Step 1: Pause Leasing and Document the Result

Stop leasing the unit until the hazard is corrected. Pull the lab report and note the specific surfaces that failed, windowsill, floor, window well, because the remediation scope follows the failed surface, not the whole unit. Keep the original lab report; it establishes the baseline that the retest will be measured against.

Step 2: Notify the Tenant in Writing

Notify the tenant in writing of the identified hazard and the planned response. A written notice with a date protects both sides: it shows the tenant was informed promptly, and it starts the clock on your response timeline. Verbal notice alone is hard to prove later if an inspector or tenant questions the timeline.

Step 3: Choose Interim Controls or Abatement

The response depends on what failed and how badly:

• Interim controls, stabilizing deteriorating paint, sealing or enclosing surfaces, cleaning with lead-safe methods, and controlling dust. These are appropriate when the hazard is localized and the paint is intact enough to stabilize.
• Abatement, permanently eliminating the hazard through removal, enclosure, or replacement of the lead-painted component. This is a larger scope and typically requires a certified abatement contractor.

Localized dust failures on windowsills and floors are often addressed with interim controls plus a thorough lead-safe cleaning, while deteriorated paint on multiple components may call for abatement. The failed surface tells you which path applies.

Step 4: Use Lead-Safe Work Practices, Not Dry Sanding

Watch out: dry scraping or power sanding a painted surface spreads lead dust through the unit and can create a bigger violation than the one you started with. Deteriorating paint should be stabilized, not sanded dry. Use lead-safe work practices, wet methods, plastic containment, HEPA cleanup, and hire a certified firm for the repair work rather than a general handyman.

Step 5: Retest Before Re-Occupancy

Retest the failed surfaces with dust wipe sampling before the unit is re-leased or re-occupied. The retest is what converts a corrected hazard into a documented clean result, and it is the evidence a licensing reviewer or tenant will ask for. Do not rely on a visual inspection alone; lead dust is invisible when it is at hazardous levels.

Step 6: Keep Every Record

Keep every invoice, contractor certification, lab report, and retest result. They are your defense if a tenant or inspector questions the timeline, and they form the paper trail that supports the certificate filing. A clean retest with no documentation is weaker than a clean retest with a complete file.

What This Means for Your Certificate

If the failed unit was headed toward a Lead-Safe Certificate, the remediation and retest are what get you there. Our guide to getting Lead-Safe Certification covers the filing steps, and our lead dust wipe test guide explains dust wipe sampling. If a hazard has already been identified and you need a retest scheduled quickly, contact our team to book the inspection.
