State law data last updated: 2026-02-02

Overview

Shreveport receives roughly 48.9 inches of precipitation per year at an average of 67.5 F, which means it experiences frequent wet weather.

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

Shreveport has a humid subtropical climate with long summers and frequent thunderstorms, so indoor moisture can build up quickly after leaks.

Shreveport Residential Rental and Inspection Program ensures rental properties meet health and safety standards.

Shreveport's Residential Rental Inspection program checks rentals for health and safety code compliance.

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

State Laws and Rights

Louisiana mold law snapshot

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

Under Louisiana Civil Code Article 2691, landlords are bound to make all repairs necessary to maintain the rental property in a condition suitable for the purpose for which it was leased. This is known as the implied warranty of habitability. The landlord must provide a rental that is free of vices or defects that prevent its use as intended. This includes maintaining functional plumbing, heating and cooling systems, electrical systems, and addressing health hazards such as mold. This duty exists even if not mentioned in the lease agreement.
