Pet Rent vs Pet Deposit Calculator
Pet rent is recurring and non-refundable — pet deposits are refundable minus damage, with an optional non-refundable fee. Which structure costs the tenant less depends on how long you stay. This calculator finds the break-even.

How the math works
Landlords increasingly charge pet rent instead of (or on top of) a refundable deposit — because pet rent never has to be returned. For a tenant, the math flips with length of stay: short tenancies favor the deposit path, long tenancies favor the deposit because cumulative pet rent exceeds deposit-plus-fee.
California caps combined deposits (including pet) at two months' rent (three if furnished). Colorado, Nevada, and a handful of other states have similar caps. Non-refundable pet fees are prohibited in California and a few other states — what landlords call a fee must be refundable if not used. ESA and service animals are exempt from pet fees under federal FHA.

Frequently Asked Questions
Does pet rent reset each year?
Usually yes. Pet rent typically tracks the same annual escalator as base rent, so a $45/month pet rent becomes $47-$48/month after a standard 3-5% increase.
Is a non-refundable pet fee legal?
Depends on the state. California, Massachusetts, and New Jersey require all pet money to be refundable. Texas, Florida, and most others allow non-refundable fees. Always check state landlord-tenant law before paying.
Can the landlord charge both pet rent and a deposit?
Yes in most states. Combined pet rent plus deposit is legal but should be disclosed in the lease's pet addendum. Watch for state deposit caps — California limits total deposits (including pet) to 2-3 months' rent.
Do ESAs pay pet rent?
No. Under the federal Fair Housing Act, emotional support animals and service animals are not pets — no pet rent, no pet deposit, no breed restrictions. Landlord can request reasonable documentation but cannot charge pet fees.
