State Mold Laws — Verified Guides
Mold law is state law: habitability standards, landlord repair timelines, tenant remedies, seller disclosure and insurance treatment all differ by state. Each guide below was researched from primary statutes and then independently re-verified citation by citation. States still marked “in verification” haven't cleared that second check yet — we publish nothing that hasn't.
Every published guide passed adversarial citation verification against primary statute text (August 14, 2026).
