Overview
Norfolk receives roughly 49.2 inches of precipitation per year at an average of 61.6 F, which means it experiences frequent wet weather.
The broader Virginia climate, including seasonal humidity peaks and storm activity, shapes the indoor moisture environment alongside local conditions.
Norfolk has a coastal setting with tidal waterways, so humidity stays high and drying times can be long after rain.
Neighborhood Quality enforces statewide building and property maintenance codes for public health and safety.
Norfolk Neighborhood Quality enforces the Virginia Uniform Statewide Building Code and the International Property Maintenance Code.

Warning Signs of Mold in Norfolk
Watch for these signs that moisture is lingering in Norfolk homes and rentals:
- Condensation forming on glass during Norfolk warm seasons (average temp 61.6 F) suggests indoor humidity needs attention.
- Musty odors in closets or crawlspaces.
- Condensation that returns on windows each morning.
- Peeling paint near baseboards or window trim.
- Staining around vents or ceiling corners.
- Soft drywall around tubs or showers.

Mold Risk Factors in Norfolk
These are the most common moisture drivers for homes and rentals in Norfolk:
- At roughly 49.2 inches of rain per year, Norfolk properties need regular checks for roof, window, and foundation leaks.
- Tidal humidity can keep basements and crawlspaces damp.
- Frequent rain events shorten drying windows after leaks.
- Moist marine air raises indoor humidity in living spaces.
- Thunderstorms can drive wind-driven rain at windows and doors.
- Ductwork in closets can sweat during peak cooling.

Norfolk Seasonal Risk Calendar
Winter
Cool, damp spells raise condensation on windows and exterior walls.
Spring
Rainy stretches keep crawlspaces damp. Check grading.
Summer
An average of 61.6 F drives extended cooling seasons. Monitor HVAC condensate and use dehumidifiers in below-grade spaces.
Fall
Coastal storms and windy rain test roofs and siding.

Norfolk Moisture Playbook
Use this short playbook to stay ahead of common moisture problems in Norfolk.
After a Leak
Stop the leak, remove wet materials within 24 to 48 hours, and dry the area with airflow.
Monthly Maintenance
Check crawlspace humidity, clear condensate lines, and inspect window seals.
Seasonal Tune Up
With 49.2 inches of rainfall annually, pre-season gutter cleaning, flashing inspections, and humidity monitoring (30 to 50 percent) are key.

Mold Prevention in Norfolk
Use these priorities to keep indoor humidity low and avoid recurring growth:
- Keep gutters clear and downspouts extended to manage the 49.2 inches of precipitation this area receives each year.
- Maintain indoor humidity between 30 and 50 percent.
- Dry wet materials within 24 to 48 hours.
- Vent bathrooms and kitchens outdoors.
- Clear gutters and direct downspouts away from foundations.
- Inspect window and door seals before storm season.
- Service HVAC condensate drains annually.

State Laws and Rights
Virginia mold law snapshot
Virginia has mold-specific rules in addition to general habitability standards.
Under the Virginia Residential Landlord and Tenant Act, landlords must comply with applicable building and housing codes materially affecting health and safety, make all repairs necessary to keep the premises in fit and habitable condition, and maintain the premises to prevent moisture accumulation and mold growth. The implied warranty of habitability is codified in Section 55.1-1220, which requires landlords to maintain electrical, plumbing, heating, ventilating, and air-conditioning systems in good working order. Mold that results from landlord failure to maintain the premises or address water intrusion may constitute a breach of the warranty of habitability.
