Three pet charges, three different meanings. Pet rent is monthly (averaging $35.65 in 2025) and never comes back. A pet fee is one-time (about $315 on average) and never comes back. A pet deposit (around $250) is one-time and refundable if your pet doesn't damage anything. Added up, the average dog costs about $743 in year one and $428 a year after that — before you buy a single bag of food. Here's how the three charges compare, which ones cost you most, and where the law draws lines.
| Charge | Typical range | 2025 average | Refundable | Repeats? |
|---|---|---|---|---|
| Pet rent | $10 – $60/mo | $35.65/mo | No | Every month |
| Pet fee | $150 – $500 | ~$315 | No | Once (per pet) |
| Pet deposit | $200 – $500 | ~$250 | Yes, less damages | Once (per pet) |
Averages come from RentCafe's 2025 survey of pet-friendly apartment listings and property-management industry data. Every number is per pet at most buildings — two cats means two of everything, though some landlords cap charges per apartment or discount the second animal.

On a 12-month lease, a $315 fee and $35 monthly rent are almost identical ($315 vs $420), and the refundable $250 deposit is the cheapest of all if your pet behaves — you get it back. Stretch to a three-year stay and the picture changes completely:
| Lease length | $35/mo pet rent | $315 fee (once) | $250 deposit (refundable) |
|---|---|---|---|
| 1 year | $420 | $315 | $0 if refunded |
| 2 years | $840 | $315 | $0 if refunded |
| 3 years | $1,260 | $315 | $0 if refunded |
| 5 years | $2,100 | $315 | $0 if refunded |
This is why the industry has shifted hard toward monthly pet rent: it's the charge that keeps growing. If you plan to stay put, negotiating a larger one-time deposit in place of monthly rent can save four figures over a long tenancy. If you move often, the reverse is true — one-time fees hurt most when you pay them every year at a new building.
Three reasons, all economic. First, recurring revenue beats one-time revenue, especially when management companies report monthly income. Second, deposits are regulated — many states cap total security deposits and require returning them with itemized deductions within a deadline, while pet rent has almost no restrictions anywhere. Third, legal shifts accelerated the move: California's AB 12, effective mid-2024, folds pet deposits into a security-deposit cap of one month's rent, so a landlord who used to collect two months of deposit plus a pet deposit now can't. Monthly pet rent stayed untouched, and much of that deposit money converted straight into pet rent.
Here's the rule that overrides all the others: under the federal Fair Housing Act, service animals and emotional support animals are not pets. A landlord cannot charge pet rent, a pet fee, or a pet deposit for them — not $10 a month, not a dollar. What a landlord can do is request reliable documentation of the disability-related need (for ESAs, typically a letter from a treating professional), charge for actual damage the animal causes just like any other damage, and hold the animal to legitimate conduct rules. A "pet screening fee" applied to an assistance animal is equally off-limits. If you run into a blanket policy, a note referencing fair-housing rules — or a call to a local tenant-rights group — usually resolves it.
It depends on how long you stay. A $250 refundable deposit costs you nothing if your pet does no damage, while $35 monthly pet rent costs $420 a year — so short stays favor deposits. Stay four years and the deposit is still $250 while pet rent has hit $1,680. The catch: landlords know this, which is why many have dropped deposits for rent and fees.
In most states, yes — pet rent, a pet fee, and a pet deposit can all be charged together, and they're typically quoted per pet. A few states fold pet deposits into the overall security-deposit cap (California's one-month cap, effective 2024, includes them), but that limits the deposit, not the monthly rent or non-refundable fee.
Yes. Under the federal Fair Housing Act, assistance animals — service animals and emotional support animals with reliable documentation — are not pets, so pet rent, pet fees, and pet deposits can't be charged for them. The landlord can still charge for actual damage and can verify the disability-related need, but a blanket 'pet rent' charge on an ESA violates fair housing rules.
More than you'd think — especially at smaller landlords and in softer rental markets. Offering a larger refundable deposit in place of monthly rent, signing a longer lease, or showing vaccination and training records all work as bargaining chips. The numbers are small enough that many landlords would rather fill the unit than hold out for $35 a month.
At the 2025 national averages — $35.65 a month pet rent plus a $315 one-time fee — a single pet costs about $743 in the first year and $428 every year after. Two pets at the same charges run roughly $1,485 in year one. Over a three-year lease, one pet at average charges costs about $1,598.
