State Laws and Rights
Texas mold law snapshot
Texas has mold-specific rules in addition to general habitability standards.
Texas recognizes an implied warranty of habitability requiring landlords to maintain rental properties in a condition fit for human habitation. Under Texas Property Code Section 92.052, landlords must make a diligent effort to repair conditions that materially affect the physical health or safety of an ordinary tenant. While mold is not specifically mentioned in the statute, courts have applied this standard to mold issues when they pose health risks. Examples of conditions affecting health and safety include sewage backups, roaches, rats, no hot water, faulty wiring, and roof leaks. Mold caused by these types of conditions falls under the landlord's duty to repair.
