Louisville’s Older Homes: 5 Hidden Lead Hazards
Owning or managing older rental properties in Louisville comes with unique challenges. One of the biggest is lead. While lead-based paint was banned in residential use in 1978, many of Louisville’s older homes and multifamily properties still contain it, often in places you can’t easily see.
These hidden hazards can put tenants at risk, create costly code violations, and leave landlords exposed to liability.
1. Lead Paint on the Exterior that Contaminates Soil
Even if exterior paint looks intact, older layers of lead paint may still be underneath. Over time, weathering and repainting can cause lead dust and chips to fall into the soil around a property. Children playing in the yard or tenants working in garden beds may then be exposed.
It’s not just your property that matters. If a neighboring house has deteriorating lead paint, that dust can migrate into your soil, too. Once lead is in the soil, it can be tracked indoors on shoes, pets, and strollers, contaminating carpets and floors.
2. Dust Tracked into Homes
Lead-contaminated soil doesn’t stay outside. Shoes, pets, and even HVAC systems can carry dust into hallways and living spaces. Over time, that dust can build up on floors and window sills, creating exposure risks, especially for young children who are most vulnerable to lead’s health effects.
Routine cleaning helps, but once soil is contaminated, dust will continue to reappear until the source is identified and addressed.
3. Lead Paint Under Newer Layers
Just because walls, doors, or trim have been repainted doesn’t mean lead is gone. Many friction and impact surfaces, such as windows, doors, stairs, and banisters, may have multiple layers of paint with lead hidden beneath the topcoat.
When these surfaces rub, stick, or slam shut, they create fine lead dust that settles on floors and other surfaces. Even if the top layer isn’t lead-based, friction can release particles from the older layers underneath.
4. Common Areas in Rental Properties
In multifamily housing, lead hazards often show up in shared spaces such as stairwells, laundry rooms, hallways, and exterior siding. Dust and debris from these areas can easily spread into occupied units, putting multiple households at risk.
Louisville Metro Code of Ordinances Chapter 156 requires landlords to maintain rental properties in a lead-safe condition. This means even common areas must be monitored and addressed if lead paint hazards are present.
5. Renovation and Maintenance Work
Ordinary repair work such as sanding, drilling, or replacing windows can release large amounts of lead dust if contractors aren’t following safe practices.
Under EPA’s Renovation, Repair and Painting (RRP) Rule, anyone performing renovation in pre-1978 housing must be trained and certified in lead-safe work practices.
For landlords, this means you’re responsible for ensuring any contractor you hire follows the rule. Failing to do so can lead to costly fines and, more importantly, health risks for your tenants.
Why This Matters: Health Risks from Lead
Lead is toxic even at very low levels. According to the CDC, children exposed to lead can experience learning problems, lower IQ, behavioral issues, and delayed growth. Adults can suffer from high blood pressure, kidney damage, and reproductive issues. There is no safe level of lead exposure.
That’s why Louisville Metro Government, the Kentucky Cabinet for Health and Family Services, and federal agencies like EPA and HUD all regulate lead hazards in housing.
What Louisville Landlords Need to Know
Local rules apply
Louisville Metro requires landlords to maintain safe, habitable housing at all times. Lead hazards are included under this duty, and properties must be kept in compliance with local codes.
Rental housing is a priority
Modern, energy-efficient, tightly sealed buildings often trap humidity indoorsHUD’s Lead-Safe Housing Rule (24 CFR Part 35) and Louisville Metro enforcement mean landlords must address hazards promptly.
Testing is the first step
Lead paint, soil, and dust hazards are not always visible. Certified testing provides the evidence needed to identify risks and meet health and safety requirements.
Documentation matters
Keeping records of inspections, risk assessments, and contractor compliance can protect you in the event of a tenant complaint or code inspection.
