Yes. A no-pets lease is generally legal in Texas. A landlord can ordinarily include a lease term prohibiting ordinary household pets. However, a no-pets clause is not absolute. Federal and Texas fair-housing protections can require an exception when a tenant needs an assistance animal because of a disability.
Can a Texas Landlord Ban Pets?

Generally, yes. Texas law does not create a general right for residential tenants to keep pets. A landlord can establish lease rules prohibiting pets, subject to fair-housing and other legal requirements.
If the lease clearly prohibits pets, a tenant who keeps an ordinary pet without permission may violate the lease. The landlord can then use remedies available under the lease and Texas landlord-tenant law.
Are Assistance Animals an Exception?
Yes. This is the most important exception.
Under the federal Fair Housing Act, assistance animals are not treated as ordinary pets when they are needed because of a disability. HUD explains that a reasonable accommodation may require a housing provider to make an exception to a no-pets policy so a person with a disability has an equal opportunity to use and enjoy a dwelling.
Assistance animals can include animals that perform tasks or provide disability-related emotional support. An assistance animal does not have to be individually trained or certified under the Fair Housing Act.
Can a Landlord Charge a Pet Deposit?
Generally, not for an approved assistance animal. HUD states that assistance animals are not pets for Fair Housing Act purposes, so housing providers generally cannot impose pet fees or deposits on them merely because the animal is present.
Does Texas Protect Service Animals?
Yes. Texas law provides housing protections for people using service animals. The Texas Workforce Commission states that a property with a “no-animals” policy must allow a person who uses a service animal to keep the animal, subject to applicable legal requirements.
Texas Human Resources Code Section 121 defines an assistance or service animal for these purposes as a canine specially trained or equipped to help a person with a disability. The statute also contains an exception involving a single-family residence where the occupants rent or furnish for compensation only one room.
Can a Landlord Ask for Documentation?
A landlord may have limited rights to request information when the disability or disability-related need for an assistance animal is not obvious. HUD guidance permits housing providers to evaluate whether an accommodation is necessary and reasonable.
What If a Tenant Secretly Keeps a Pet?
If the animal is an ordinary pet and the lease prohibits pets, secretly keeping it can constitute a lease violation. The landlord can enforce the lease according to Texas law.
But if the tenant says the animal is an assistance animal, the landlord should evaluate the request under applicable fair-housing requirements rather than automatically treating the animal as an unauthorized pet. HUD specifically identifies exceptions to no-pets policies as a common reasonable accommodation.
Can a No-Pets Rule Apply to Everyone?
Generally, a landlord may apply a legitimate no-pets policy consistently to ordinary pets. Fair-housing laws, however, prohibit disability discrimination and can require reasonable accommodations.
A landlord who refuses a legally required accommodation may face a fair-housing complaint or other legal consequences. Texas Workforce Commission guidance identifies failure to grant a reasonable accommodation to a no-pets rule as a potential housing-discrimination issue.
Are There Exceptions for Owner-Occupied Homes?
Yes. Federal and Texas law contain specific exceptions affecting certain small housing arrangements. Whether an exemption applies can depend on the property’s ownership, occupancy, number of units, and other facts.
The Texas service-animal statute specifically excludes a single-family residence whose occupants rent or furnish for compensation only one room from its definition of “housing accommodations.”
What Should Landlords and Tenants Do?
Landlords should state pet restrictions clearly in the lease, apply them consistently, and establish a process for handling accommodation requests. Tenants should review the lease before bringing an animal onto the property and request an accommodation when an animal is needed because of a disability.
Conclusion
A no-pets lease is generally legal in Texas, and landlords can ordinarily prohibit ordinary household pets. The rule has important exceptions, particularly for assistance animals required because of a disability. Federal fair-housing law can require a reasonable exception to a no-pets policy, while Texas law separately protects certain people who use service animals.
The legality of a particular provision can depend on the property, landlord, animal, and circumstances.
