Most states let landlords charge pet rent, pet deposits, and one-time pet fees, as long as the lease spells them out. But there are limits — and some animals don't legally count as "pets" at all.
Charging an extra $25–$75/month per pet is allowed if your lease lists it. Some city ordinances cap pet fees, but state law in TX, AZ, NV, and NM does not.
In states that cap total deposits (like Arizona's 1.5x rule and Nevada's 3-month rule), pet deposits usually count toward the cap. Non-refundable pet fees typically do not.
Under the federal Fair Housing Act, service animals and emotional-support animals (with proper documentation) are accommodations, not pets. Landlords cannot charge pet rent, pet deposits, or pet fees for them.
Most states allow breed and weight restrictions in pet policies, though insurance carriers often drive them. HOAs and condo associations can add their own rules on top.
Verbal "sure, the dog's fine" assurances rarely hold up. Always have the pet, the fees, and any restrictions written into the lease or a signed addendum.
