The Northeast just made lead testing the law.
In the last two years, Rhode Island, New Jersey, Connecticut, and New York have all started requiring older rental homes to be checked or certified for lead paint. That is hundreds of thousands of apartments that now need attention, on a deadline, and most programs do not have enough certified inspectors to keep up. Here is what changed, state by state, and how a low-cost field test and a free risk map help close the gap.
For lead programs Open the risk mapWhat changed
Rhode Island now puts every rental in a statewide registry, and older units need a lead certificate. Anyone can look up an address online to see its status.
New York launched a statewide Lead Rental Registry in November 2025. Older rentals in two dozen communities have to register and be inspected every three years. New York City runs its own, stricter version.
New Jersey requires every pre-1978 rental in the state to be inspected for lead every three years, or whenever a tenant moves out, and to carry a lead-safe certificate.
Connecticut lowered the blood-lead level that triggers a full home investigation, which sharply increased how many homes get inspected each year.
Who has what, across the Northeast
Some states publish the results down to the address. Others have the law but keep the data private. A few have nothing yet.
| State | The law | Is the data public? |
|---|---|---|
| Rhode Island | Statewide rental registry plus a lead certificate for older units (2024). The state put it online. | Public, by address |
| Massachusetts | The Lead Law. Older homes must be made lead-safe, with a Letter of Compliance on file. | Public, by address |
| New York | A statewide Lead Rental Registry took effect November 2025 for older rentals in two dozen communities. New York City runs its own stricter rules. | Law on the books; NYC and Rochester data are public |
| New Jersey | Every pre-1978 rental must be inspected for lead every three years or at turnover, and carry a lead-safe certificate (2023). | Law on the books; statewide dashboard only |
| Connecticut | A 2025 overhaul lowered the blood-lead level that triggers a full home investigation, sharply raising how many homes get inspected. | Law on the books; not public |
| Pennsylvania | No statewide law. Philadelphia requires a lead-safe certificate for older rentals; Lancaster has its own program. | Philadelphia is public, by address |
| Vermont | Owners of older rentals must file annual lead-safety compliance statements with the state. | Public (recent filings only) |
| Maine | A statewide lead-safe rental registry, landlords opt in and are rated lead-free, lead-safe, or lead-maintained. | Public (opt-in) |
| New Hampshire | Newly converted older rentals need a lead-safe certificate (2024). The state and some counties publish a lead-safe registry. | Public (grant-limited) |
The catch: there are not enough people to do the work
The limit is crews, not budget.
Every one of these laws assumes a certified inspector is available to check the home. The reality is the opposite. There are not enough licensed lead inspectors and abatement crews to cover every old apartment on the timelines the laws set. Programs sitting on millions in grant money still cannot spend it, because the bottleneck is people, not money.
Where FluoroSpec fits
FluoroSpec is a low-cost field test. You spray a small amount of a reagent (methylammonium bromide) on a surface, and under a UV flashlight it glows bright green wherever there is lead paint or lead dust.
It is not a replacement for the certified inspection the law requires. It is the fast, cheap step before it. A program or a landlord can screen a lot of units quickly, see which ones almost certainly have lead, and send the scarce certified inspectors to those first. Crews also use it to check that dust is gone before and after the work.
Stretch the grant further
Screening first means you do not spend a full certified inspection on a unit that turns out clean. Every dollar you save on the homes that do not need work is a dollar that covers another home, so the same grant reaches far more families.
Expand the primary-prevention side of your grant
Cheap, fast screening lets you find and address lead before a child is ever exposed, instead of only responding after a blood test comes back high. That is the primary prevention your HUD grant is meant to grow, and low-cost testing is how you scale it.
Find the oldest units first
A field test tells you about one wall. The map tells you which buildings to walk into first. We built a free national lead-risk map from public records, taken all the way down to the individual home, and checked it against real measured childhood blood lead in eleven states. A program can rank its older rentals by risk and point both its inspectors and its kits where the lead concentrates.
National risk map The eleven-state validation Read the white paperFluoro-Spec Inc. manufactures the reagent under a U.S. EPA-authorized Low Volume Exemption under TSCA Section 5 (40 CFR 723.50), and the finished kit is sold in commerce today. Public lead programs already purchase it, including New Hampshire DHHS and the City of Columbus. Full regulatory disclosures, including the methylammonium bromide composition and the TSCA, DEA, and OSHA posture, are on our Safety & Compliance page.
Put it to work in your program
I will send your program 25 kits free to put in the field, no cost and no commitment, and build the risk map of your county with you.
