Mold Risk Factors in Tulsa
These are the most common moisture drivers for homes and rentals in Tulsa:
- Climate records show Tulsa getting 42.1 inches of annual precipitation, so storm events and small leaks both matter.
- Higher humidity slows drying after leaks.
- Thunderstorms bring heavy rain that tests roofs and siding.
- Warm seasons increase cooling and condensate loads.
- Crawl spaces and lower level storage areas can stay damp.
- Plumbing leaks in multi unit buildings can spread moisture.

Tulsa Seasonal Risk Calendar
Spring
Thunderstorms return. Check roof edges and window seals.
Summer
Year-round cooling demand at 61.5 F average means condensate management and lower-level dehumidification are essential.
Fall
Warm days and cool nights can create condensation. Watch closets and window sills.
Winter
Cold snaps can create window moisture. Keep airflow steady.

Tulsa Moisture Playbook
Use this short playbook to stay ahead of common moisture problems in Tulsa.
After a Leak
Stop the leak, remove wet materials within 24 to 48 hours, and dry with airflow and dehumidification.
Monthly Maintenance
Inspect under sinks, clear condensate lines, and check crawl space vents.
Seasonal Tune Up
Before storm season, clear gutters and inspect flashing; about 42.1 inches of annual precipitation means small leaks can add up.

Mold Prevention in Tulsa
Use these priorities to keep indoor humidity low and avoid recurring growth:
- Gutters and downspouts need regular clearing to handle 42.1 inches of yearly precipitation and keep water away from the foundation.
- Maintain indoor humidity between 30 and 50 percent.
- Dry wet materials within 24 to 48 hours.
- Vent bathrooms, kitchens, and laundry rooms outdoors.
- Clear gutters and direct downspouts away from foundations.
- Inspect exterior caulk lines and window seals seasonally.
- Service HVAC condensate drains annually.

State Laws and Rights
Oklahoma mold law snapshot
Oklahoma does not have a mold-specific statute, but habitability rules still apply.
Under Oklahoma Statutes Section 41-118, landlords must at all times during the tenancy: (1) keep all common areas in a clean, safe, and sanitary condition (except for single-family residences); (2) make all repairs and do whatever is necessary to put and keep the tenant's dwelling unit and premises in a fit and habitable condition; (3) maintain in good and safe working order all electrical, plumbing, sanitary, heating, ventilating, air-conditioning, and other facilities and appliances supplied by the landlord; and (4) provide appropriate receptacles for waste removal. This implied warranty of habitability applies whether or not the lease explicitly states it and even if the lease attempts to waive the obligation.
