Mold Law by State: Washington DC, Virginia, New Jersey, Florida & New York Compared

Mold law in the United States isn’t one law — it’s a patchwork of landlord-tenant statutes, real estate disclosure doctrine, and contractor-licensing regimes that vary state by state, sometimes city by city within the same state. We operate across five of the most legally divergent jurisdictions in the country — Washington DC, Virginia, New Jersey, Florida, and New York — and the differences are large enough that “what does the law require” genuinely has five different answers depending on where the property sits. This guide puts them side by side.

Washington, DC

DC has the most specific and fastest-moving statutory framework of the four. Under the District’s mold law, a landlord who receives written or electronic notice of mold or suspected mold must inspect within 7 days, and must remove any visible mold found within 30 days of that inspection (faster if a court orders it). Disclosure is required for known mold at or above the DOEE threshold of 10 square feet occurring in the prior three years, unless it was remediated by a licensed indoor mold remediation professional. Above that 10-sq-ft threshold, DC requires a licensed indoor mold assessor and remediator — below it, an unlicensed party may legally do the work.

The enforcement landscape shifted materially in 2026: as of 12 June 2026, DOEE no longer conducts residential mold complaint inspections for rental-housing mold violations, which changes the practical path tenants have for getting a city inspection. The private remedy remains intact — a court can award treble damages where a tenant discovered mold, a professional assessment confirmed contamination above threshold, the owner was notified, and the owner failed to remediate within 60 days in bad faith.

Virginia

Virginia’s mold law is the newest and, since a 2024 update, one of the fastest-moving of the five. Under the Virginia Residential Landlord and Tenant Act, landlords must maintain the premises to prevent moisture accumulation and mold growth, and must provide tenants an itemized move-in inspection report — within 5 days of move-in — disclosing any visible mold in readily accessible interior areas (Va. Code § 55.1-1215). If the tenant decides to stay after that disclosure, the landlord must remediate within 5 days of that decision. On any later notice of mold during the tenancy, the landlord must remediate in accordance with professional standards published by the EPA, HUD, or a consistent industrial-hygienist standard, using ordinary care, and reinspect to confirm the mold is gone (Va. Code § 55.1-1220, cross-referencing § 8.01-226.12). Tenants carry a parallel duty not to cause or conceal mold conditions (§ 55.1-1227), and where remediation requires it, have a statutory right to temporary relocation (§ 55.1-1231).

Unlike DC, Florida, and New York, Virginia has no dedicated state mold assessor/remediator license — DPOR is still studying whether one is warranted. What Virginia does require, since the 2024 Virginia Consumer Protection Act update, is that firms and individuals performing mold remediation hold IICRC certification (or an equivalent nationally/internationally recognised credential); contractors also need a general Class A or B DPOR contractor license if the work falls within licensed home-improvement scope. Arlington and Alexandria — both real MoldAct service areas — sit entirely under this Virginia framework, not DC’s, despite being minutes from the District.

New Jersey

New Jersey is the outlier of the four: no mold-specific landlord statute and no state mold contractor license. A bill to create one — the Mold-Safe Housing Act — has been reintroduced in the Legislature repeatedly since at least 2013 (versions in 2018, 2022, and 2024), sponsored primarily by State Sen. Robert Singer, and has never passed. Any general contractor can legally perform mold remediation work in NJ today without a mold-specific credential. The only verifiable credentials a NJ homeowner or tenant can check are NJHIC (Home Improvement Contractor) registration and voluntary IICRC certification (AMRT, WRT, ASD) — see our full breakdown in New Jersey Mold Remediation Licensing Requirements.

Florida

Florida has no standalone mold disclosure statute — but that doesn’t mean sellers are off the hook. The Florida Supreme Court’s Johnson v. Davis (480 So. 2d 625, Fla. 1985) decision created a common-law duty for sellers to disclose known, material defects — including known mold — that a buyer wouldn’t discover through reasonable inspection. In practice, disclosure happens through the standard FR/Bar seller’s property disclosure form, not a dedicated statute. Where Florida does regulate directly is contractor licensing: DBPR licenses mold assessors and remediators separately under Chapter 468, Part XVI, for any job over 10 square feet, and the same firm generally cannot both assess and remediate the same property within 12 months — a built-in conflict-of-interest check.

New York

New York layers two protections. Statewide, Real Property Law § 235-b (the warranty of habitability) applies to every residential lease and cannot be waived — a serious, ongoing mold condition tied to an unfixed leak can breach it, supporting a rent-abatement claim in Housing Court. In New York City specifically, buildings with three or more units carry an additional, more proactive duty under Local Law 55 of 2018 (the Asthma-Free Housing Act): annual inspections (not just complaint response), safe-work-practice remediation standards, a required tenant notice, and 3-year recordkeeping, enforced by HPD. Separately, Labor Law Article 32 (the 2015 Mold Law) licenses Mold Assessors, Remediation Contractors, Supervisors, and Abatement Workers statewide — with the same independent-assessor-before-remediator split seen in Florida.

The Practical Takeaway Across All Five

Two patterns hold regardless of jurisdiction. First, “no mold-specific statute” never means “no legal duty” — Florida and (outside NYC) New Jersey both still carry disclosure or habitability obligations through general common law or statute, just not a named mold law. Second, where a state licenses mold professionals (DC, Florida, New York) or mandates a specific certification (Virginia), verifying that credential is the single highest-leverage step a homeowner or tenant can take before relying on remediation work — and where nothing is mandated (New Jersey), IICRC certification is the only meaningful credential left to check regardless. In every jurisdiction, documentation — written notice to a landlord, dated photos, an independent assessor’s report, clearance testing after remediation — is what actually decides how a dispute resolves, whether or not a specific statute names mold.

Frequently Asked Questions

Which of these five jurisdictions has the strongest tenant mold protections?

Washington DC and New York City have the most specific statutory protections — DC’s mold law sets fixed inspection and removal deadlines with treble-damages exposure for bad-faith landlords, and NYC’s Local Law 55 requires annual proactive inspections, not just complaint-driven response. Virginia’s 2024 update is the newest and fastest-moving of the five — a landlord who receives actual notice of mold must remediate to EPA/HUD professional standards, and within 5 days of a tenant deciding to stay after move-in disclosure. Florida and New Jersey rely more heavily on general habitability doctrine and case-by-case disclosure duties rather than mold-specific statutes.

Which state has no mold contractor licensing at all?

New Jersey. Unlike DC (licensed indoor mold assessors/remediators above the 10-sq-ft threshold), Virginia (2024 law requires IICRC certification for remediators, though there’s no dedicated state mold license — a general DPOR Class A/B contractor license covers the home-improvement scope), Florida (DBPR-licensed assessors and remediators under Chapter 468, Part XVI), and New York (DOL-licensed assessors, remediation contractors, supervisors, and abatement workers under Labor Law Article 32), New Jersey has never passed the repeatedly-reintroduced Mold-Safe Housing Act and has no state mold-specific credential to check.

Does “no mold disclosure statute” mean a seller doesn’t have to disclose mold?

No. Florida has no standalone mold disclosure statute, but sellers still carry a common-law duty to disclose known, material mold conditions under Johnson v. Davis (Fla. 1985) — the absence of a named statute doesn’t mean the absence of a legal duty.

Is Arlington or Alexandria, Virginia covered by DC’s mold law?

No. Arlington and Alexandria are Virginia jurisdictions, governed entirely by the Virginia Residential Landlord and Tenant Act (Va. Code §§ 55.1-1215, 1220, 1227, 1231) and Va. Code § 8.01-226.12 — not DC’s mold law, which applies only within the District itself. The two frameworks share a similar spirit (a landlord duty to inspect and remediate on notice) but different timelines, thresholds, and enforcement bodies.
