Charge pet rent as its own monthly line, separate from base rent. It is the recurring price of keeping a pet. It is not a pet deposit, and it is not a one-time pet fee. An assistance animal is not a pet. You do not charge pet rent, a pet fee, or a pet deposit for an assistance animal.

What follows is general guidance, not legal advice. Pet fees, deposit caps, and assistance-animal rules differ by city, state, and province. Check the law where the unit sits, or ask an attorney.

What is pet rent, and what is it not?

Pet rent is a monthly charge the lease sets for the right to keep a pet. It is due with the rent, and it ends when the pet is gone and the lease says the charge stops. It does not sit in a refund account. You do not return it at move-out just because the unit is clean.

A pet fee is a one-time charge at the start. A pet deposit is money you hold and may have to return, minus lawful deductions for damage. Those three amounts do different jobs. Folding them into one number on the rent line hides which rule applies when the pet leaves, when the tenant disputes a deduction, or when a rent-cap statute asks what the rent actually is.

Charge When it is due Refundable? Where it posts
Pet rent Each month, with the rent No. It is a charge for that month Its own recurring line
Pet fee Once, usually at approval Only if the lease or local law says so One charge on that date
Pet deposit Once, at the start Yes, minus lawful damage deductions Security, with the deposit
Assistance animal Not a pet charge Not applicable No pet rent, fee, or deposit

Name the animal in the lease: how many, what type, and the monthly amount. If a second dog arrives later, amend the lease before you raise the pet rent. A verbal "sure, bring the other one" with no change in the charge is how the rent roll and the unit disagree.

How do you post $70 of pet rent?

Unit 6 rents for $1,700 a month. The lease allows two dogs at $35 each, so pet rent is $70. Both charges are due on the 1st. Enter the base rent first, then the pet rent, so a short payment leaves the later line open.

On April 1, 2026 you post April rent of $1,700 and pet rent of $70. The tenant pays $1,700 on April 3.

Date Description Charge Payment Balance
Apr 1, 2026 April rent $1,700.00 $1,700.00
Apr 1, 2026 Pet rent, two dogs $70.00 $1,770.00
Apr 3, 2026 Payment $1,700.00 $70.00

Oldest-first applies the $1,700 to April rent, because that charge was entered first. Pet rent of $70 stays open. The receipt says so. If you had buried the $70 inside a single $1,770 rent charge, this payment would look like a mystery short pay, and a later increase would start from a number that mixes rent and pets.

When one dog leaves on May 10, June pet rent becomes $35 if the lease says pet rent is per dog and stops when that dog is gone. May's $70 was the charge for May. Change the recurring amount for the next full month, and put the date in the lease file. Do not silently edit April.

What about an assistance animal?

The Fair Housing Act requires a reasonable accommodation in rules, policies, practices, or services when that accommodation may be necessary for a person with a disability to use and enjoy the dwelling. That duty is in 42 U.S.C. 3604. An assistance animal, including many emotional-support animals, is handled under that duty. It is not a pet you can price.

Do not charge pet rent, a one-time pet fee, or a pet deposit as a condition of allowing the animal. Do not raise the base rent because the animal is there. HUD's assistance-animal page is the agency's starting point for how to handle the request: Assistance Animals. If the animal causes damage above ordinary wear, you deal with that damage the way you deal with any other tenant damage, under the lease and the deposit statute. The monthly pet line is not a damage fund, and it is not available for an assistance animal in the first place.

Ask counsel if you are unsure whether a particular animal is an assistance animal. While you are unsure, leave the pet charges off. A pet-rent line you later reverse is harder to explain than a charge you never posted.

How does a pet deposit differ in California?

In California, a refundable pet deposit is security. Civil Code section 1950.5 defines security to include amounts held for damage and other stated uses, and it caps how much security you may demand. For security collected on or after July 1, 2024, the cap is generally one month's rent, in addition to the first month's rent paid on or before move-in. A landlord who is a natural person, or an LLC whose members are all natural persons, and who owns no more than two residential rental properties with no more than four units altogether, may collect up to two months. That two-month allowance does not apply if the prospective tenant is a service member.

The pet deposit counts toward the cap. It does not sit on top of it. Calling a refundable amount "pet rent" does not take it out of the cap. Pet rent, in this article, means a nonrefundable monthly charge for that month. If you collect it and agree to refund what is unused, you have collected security, and the cap applies.

Read the statute before you set the number. Cities can add their own rules. The state cap is not a promise that a city will allow pet rent on top.

What if the household is in Canada?

Canadian provinces regulate extra charges in their own statutes. Ontario, for example, limits what a landlord may collect beyond lawful rent, and a separate pet premium can be an illegal charge even when the tenancy allows the animal. Before you add pet rent to an Ontario unit, read the Residential Tenancies Act or ask counsel who practices there. Do not copy a US pet-rent clause into a Canadian lease and assume the monthly line is valid.

The ledger habit is the same either way. If a charge is lawful, it gets its own line, its own amount, and an end date. If it is not lawful, it does not get a line.

What should the lease and the receipt say?

The lease should state the number and type of pets, the monthly pet rent, the due date, and the month the charge stops if the pet leaves. It should say that damage is handled under the deposit clause, not by relabeling pet rent. It should say that an assistance animal is not subject to the pet charge.

The receipt for a short payment should name the open pet-rent line. "Paid $1,700, April rent paid, pet rent of $70 still open" is the sentence that prevents the dispute. Apply the next dollar to that $70 before it touches May rent, because the $70 is older.

On the owner statement, show base rent and pet rent as separate lines. The owner can see that $70 of the month's income depends on the pet addendum. If the pet leaves, the statement drops $70 and the base rent stays. That is the conversation you want at renewal, instead of a blended number nobody can split.

Set pet rent up as its own recurring charge next to base rent. In Tivio, a short payment then shows exactly which line is still open, on the tenant ledger and on the owner statement.
