State Laws and Rights

New York mold law snapshot

New York has mold-specific rules in addition to general habitability standards.

New York's implied warranty of habitability under Real Property Law Section 235-b is automatically included in every residential lease, whether written or oral. Landlords must ensure that rental premises are fit for human habitation and free from conditions that would be dangerous, hazardous, or detrimental to the life, health, or safety of occupants. This warranty extends to common areas used by tenants. Any lease provision that waives this right is void as contrary to public policy. Mold has been recognized by New York courts as a condition that can violate the warranty of habitability when it poses health risks or substantially interferes with the use of the premises.

Frequently Asked Questions

What are the first signs of mold in a Syracuse home?
Musty odors, condensation on windows, peeling paint, and dark spots near vents or ceilings are common early signs. If symptoms persist after cleaning, schedule an inspection.
When should I hire a mold professional in Syracuse?
If the affected area is larger than about 10 square feet, if growth returns after cleaning, or if anyone has health symptoms, hire a pro. Use the DIY vs pro guide to decide.
Do ice dams cause mold in Syracuse homes?
Ice dams trap snowmelt on roofs, which can seep into attics and walls. Proper attic ventilation and insulation help prevent them. See attic mold prevention.
How does winter condensation lead to mold in Syracuse?
Warm indoor air meeting cold surfaces creates condensation on windows and in attics. Run exhaust fans and check for wet insulation. Review prevention strategies.
What should I do about mold after a Syracuse storm?
Stop the water source, remove wet materials within 48 hours, and run fans and dehumidifiers. Photograph damage for insurance. See the storm recovery guide.
Does Syracuse humidity make mold more likely?
High outdoor humidity slows drying after leaks, which raises risk. Active ventilation and dehumidification are key. Review prevention priorities for humid climates.
