Louisville Rental Lead Testing Law: Registry Changes 2025

Kentucky House Republicans, led by Representative Ryan Dotson, threatened to pass House Bill 173, a state bill that would have prohibited any Kentucky local government from maintaining a rental property registry at all.

Facing that threat, Metro Council's amendments functioned as a negotiated concession rather than a voluntary policy shift. Losing HB 173's fight would have meant Louisville couldn't maintain any rental registry whatsoever; weakening the existing ordinances preserved the city's authority to keep a registry in some form.

O-055-25 amended sections 119.01, 119.02, and 119.03 of the Louisville Metro Code of Ordinances, governing rental housing registration, and passed 21-4. O-056-25 amended Chapter 156 covering lead-based hazards and repealed Chapter 167 entirely, passing 17-8.

Both ordinances passed on the same day, and together they reworked how the city both registers rental properties and screens them for lead hazards.

Before these amendments, landlords with pre-1978 rental units had to proactively test those units for lead hazards and submit the results to the city, feeding into a public registry tracking each property's compliance status.

That requirement existed independent of any complaint or reported health concern. A property could be flagged for testing simply because of its age, regardless of whether a tenant had ever raised an issue.

Under the amended ordinance, that proactive testing mandate is gone. Instead, a hazard risk assessment is required specifically when a child living in the unit tests positive for elevated blood lead levels, or when a complaint-based code enforcement inspection, conducted for an unrelated issue, happens to detect a potential lead hazard.

That's a fundamentally different trigger structure. The city no longer initiates lead screening on its own; screening now depends on either a documented health outcome or a complaint that brings an inspector to the property for some other reason.

Beyond lead testing specifically, the original framework also included mandatory random inspections covering 10% of rental properties in certain neighborhoods, an independent mechanism for catching problems that wouldn't necessarily surface through a tenant complaint.

That random-inspection mechanism is eliminated under the amended ordinances. Combined with the end of proactive lead testing, this removes both of the city-initiated detection paths that previously operated independently of whether a tenant complained.

Even with these changes, once a lead hazard is actually detected, whether through the child blood-level trigger or a complaint-based inspection, remediation is still mandatory within 90 days, with penalties reaching up to $1,000 per day for non-compliance.

That remediation deadline and penalty structure didn't change. What changed is how a hazard gets detected in the first place, not what happens once it's found.

This is the detail most likely to get lost in coverage focused on lead testing specifically. The amendments also removed tenant protections against landlord retaliation for filing a complaint.

That removal matters more given everything else that changed. The entire remaining detection system now depends heavily on tenants being willing to file complaints, since proactive city-initiated screening is gone. Removing retaliation protection at the same time as shifting to a complaint-driven model works against the system's own remaining detection mechanism.

The amendments also eliminated administrative fees that had previously been part of the registry and inspection framework.

For a landlord who had been budgeting for these fees as part of ongoing compliance costs, that's a straightforward reduction in the administrative burden tied to the registry, separate from the substantive testing and inspection changes.

It's worth being precise about what O-055-25 actually did to the rental registry, since "scaled back" isn't the same as "eliminated." The ordinance amended sections 119.01 through 119.03 of the rental housing registration provisions rather than repealing the registry requirement outright.

A property owner should not assume the registry itself disappeared. What changed is what triggers city attention and what data gets collected and verified through it, not whether a rental registration obligation exists at all. Separately, O-056-25 went further on the lead-hazard side by repealing Chapter 167 of the code entirely, which is a more complete removal specific to that chapter, distinct from the narrower amendment made to the registry provisions themselves.

The lead-hazard testing requirement these amendments weakened had itself only recently reached full implementation. The original ordinance, adopted in 2022, phased in its proactive testing and correction requirements for pre-1978 rental units, with that framework reportedly reaching its effective compliance point around December 2024, just months before Metro Council scaled it back.

That timeline matters for understanding the practical whiplash landlords experienced. A property owner who had only recently built proactive testing into their compliance calendar, based on requirements that had just finished phasing in, found that same obligation removed within a matter of months, well before most landlords would have completed even a first full cycle of proactive testing under the original framework.

This is worth flagging directly rather than guessing at a specific date. No source reviewed for this article, including the most detailed local reporting on the vote and its aftermath, states a separate effective date distinct from the February 27, 2025 passage date itself.

Louisville Metro ordinances typically take effect upon passage or shortly after, and nothing found in available sources suggests these particular ordinances followed a different timeline. A landlord confirming exact compliance timing should verify the current requirements directly against the codified ordinance text rather than relying solely on the passage date.

The practical starting point is updating internal compliance procedures to reflect that pre-1978 units no longer require proactive lead testing submitted to the city, while confirming staff still understand that a child's elevated blood lead test or a complaint-triggered inspection can still require a hazard risk assessment and the same 90-day remediation deadline as before.

Given that retaliation protection for complaining tenants has been removed, a landlord genuinely interested in identifying and addressing lead hazards proactively, rather than only when legally compelled to, may want to consider maintaining voluntary testing practices anyway, since the complaint-driven system this ordinance now relies on depends on tenants feeling safe enough to report concerns.
