Mold Guide for Parkersburg, West Virginia

Local mold risk drivers, seasonal priorities, and next steps for homeowners and renters in Parkersburg.

State law data last updated: 2026-02-02

Overview

Parkersburg receives roughly 42.5 inches of precipitation per year at an average of 54.2 F, which means it experiences a mix of wet spells and dry breaks.

Because West Virginia experiences a range of climate conditions, statewide humidity trends and storm patterns also influence indoor moisture levels.

Parkersburg sits in the Ohio River valley with humid summers and winter freeze-thaw, so moisture can collect in basements.

Local property maintenance code amendments establish enforcement standards for the city.

This guide highlights local moisture drivers, seasonal risk, and prevention steps. For legal rights and landlord obligations, review the West Virginia mold laws guide.

State Laws and Rights

West Virginia mold law snapshot

West Virginia does not have a mold-specific statute, but habitability rules still apply.

Under West Virginia Code Section 37-6-30, landlords must deliver the dwelling unit in a fit and habitable condition at the commencement of tenancy and maintain it thereafter. Landlords must maintain the property to meet applicable health, safety, fire, and housing codes, keep common areas clean and safe in multi-unit buildings, maintain all electrical, plumbing, sanitary, heating, ventilating, and air-conditioning systems in good working order, and supply running water and reasonable heat between October 1 and April 30. The landmark case Teller v. McCoy (1978) established that this warranty cannot be waived and applies to all residential leases.
