Your home has lead paint. Or it has mold. Or the previous tenant's activities left hazardous residues in the space. What your landlord is required to tell you, what they're required to fix, and what you can do when they don't depends on specific federal and state laws that most tenants don't know exist until they're already living with a problem.
Federal Lead Paint Disclosure Requirements Apply to Pre-1978 Housing
Federal law addresses lead paint in older housing, and landlords of covered properties generally disclose known lead paint hazards to tenants. Required disclosures: any known lead paint or lead paint hazards in the property; an EPA-approved pamphlet ('Protect Your Family from Lead in Your Home'); and inspection reports if the landlord has conducted any lead testing. Failure to disclose can carry federal civil penalties, so check the EPA or HUD site for current rules. Federal lead paint disclosure rules generally apply regardless of state, and states can add their own rules on top.
Mold Disclosure Requirements Vary Significantly by State
Some states have enacted mold disclosure or remediation rules for residential landlords, and the details vary by state. In states without specific mold statutes, mold issues may still constitute habitability violations if severe enough to affect the health and safety of occupants. The challenge: mold that develops after the tenant moves in due to a landlord's failure to fix a water intrusion problem is clearly the landlord's responsibility. Mold that develops due to inadequate tenant ventilation may be disputed. Document any water intrusion events immediately — they create the baseline for mold liability analysis.
What to Do When You Discover Mold or Lead Paint
Discovery triggers specific required actions. For mold: photograph the affected area extensively; notify your landlord in writing immediately; request written acknowledgment and a remediation timeline; and if the mold is extensive (more than 10 sq ft, per EPA guidelines) or affects occupant health, contact your local housing authority or health department. For lead paint: request your landlord's inspection records; if you have young children under 6 (the primary risk group for lead poisoning), consider professional lead testing ($200–$400 for a full inspection); notify your local health department if you discover undisclosed lead hazards. Keep written records of all notifications and landlord responses — these are essential for any subsequent claim.
Landlord Remediation Obligations Depend on Severity and State Law
For most pre-1978 housing, a federal rule calls for landlords to disclose known lead-based paint information before a lease is signed, with some exemptions (EPA, verified November 7, 2026). Whether a hazard must be removed can depend on local housing codes and state law. For mold, responsibility often depends on state law, the lease, and the cause, such as a leaking roof, failed plumbing, or inadequate waterproofing. Mold resulting from tenant behavior (not ventilating bathrooms, leaving wet materials in closets) is more disputed. When a landlord does not address serious mold or lead hazards after notice, available remedies vary by state, so ask a local attorney or legal aid office what applies.
Health Effects and Damage Claims Go Beyond Habitability
Documented health effects from lead or mold exposure can sometimes support personal injury or negligence claims; an attorney can evaluate whether that applies. These claims can involve significant damages, including medical treatment costs, ongoing health monitoring, and damages for diminished quality of life. They also require careful documentation: blood lead level tests (for lead exposure), physician documentation of respiratory symptoms (for mold), environmental testing results, and clear evidence of the landlord's knowledge and failure to remediate. A tenant rights attorney is the appropriate immediate step if health effects from housing hazards are suspected.

- Personal injury claims from lead or mold exposure can significantly exceed habitability-based remedies
Frequently Asked Questions
- Can I terminate my lease if lead paint is discovered and the landlord won't remediate?
- Often, though it depends on the state. In many places, untreated lead paint hazards that endanger children may be treated as a habitability issue; check local housing codes. Depending on state law and the lease, continued failure to remediate may give rise to remedies such as lease termination or damages; an attorney can assess your situation.
- What should I do if I discover mold in my rental?
- Photograph and document the mold location and extent. Send written notice to the landlord by certified mail identifying the location, size, and when you discovered it. Request remediation within a specified time (typically 30 days for non-emergency mold). Keep records of all communications. If the landlord doesn't respond, contact your local housing code enforcement authority.
- Does the lead paint disclosure requirement apply to commercial leases?
- No. Federal lead paint disclosure requirements are residential-only (properties used for human habitation). Commercial tenants have no federal lead paint disclosure rights, though some states have expanded disclosure requirements for certain commercial property types.
- What is an 'as-is' clause and does it waive hazard disclosure obligations?
- An as-is clause specifies that the tenant accepts the property in its current condition and the landlord makes no representations about its state. However, as-is clauses do not waive mandatory legal disclosure requirements — including federal lead paint disclosure — or liability for active concealment of known defects.
- What is a Phase I environmental assessment and when do I need one?
- A Phase I environmental assessment reviews historical records and current conditions to identify potential contamination at a commercial property. It's typically required for commercial mortgage financing and recommended for any commercial tenant signing a long-term lease on a site with manufacturing, automotive, dry cleaning, or chemical history.
