| State | Status | What the law says |
|---|---|---|
| Alabama | Capped, plus a separate pet deposit or fee | Alabama caps a security deposit at one month's rent, but a landlord may ask for more to cover pets (or alterations and increased liability risk). |
| Alaska | Capped, plus a separate pet deposit or fee | Alaska caps prepaid rent plus security deposit at two months' rent (units renting for over $2,000 a month are exempt). A landlord may add a separate pet deposit of up to one month's rent, kept apart and used only for pet damage — but not for a service animal. |
| Arizona | Capped by state law | Arizona caps security, however it is labelled (including prepaid rent), at one and a half months' rent — so a "pet deposit" counts toward the cap. |
| Arkansas | Capped by state law | Arkansas caps any security deposit, however it is labelled, at two months' rent. |
| California | Capped by state law | California caps security, however it is labelled, at one month's rent on top of the first month — two months for certain small landlords. A separate pet deposit cannot push the total past the cap. |
| Colorado | Capped, plus a separate pet deposit or fee | Colorado caps a security deposit at two months' rent. For a pet, a landlord may add a refundable pet deposit of no more than $300, and pet rent of no more than $35 a month or 1.5% of the rent, whichever is greater. |
| Connecticut | Capped by state law | Connecticut caps a security deposit at two months' rent — one month's rent for tenants aged 62 or older. |
| Delaware | Capped, plus a separate pet deposit or fee | Delaware caps a security deposit at one month's rent for leases of a year or more. A landlord may also require a pet deposit of up to one month's rent — but none for a certified support animal. |
| District of Columbia | Capped by state law | In the District of Columbia a security deposit may not exceed the initial monthly rent, may be charged only once, and must be held in an interest-bearing account. |
| Florida | No statewide cap | Florida sets no maximum security deposit — the statute regulates how a deposit or advance rent is held, disclosed and returned, not how large it may be. |
| Georgia | Capped by state law | Since July 1, 2024 Georgia caps a security deposit at two months' rent, and pet deposits count as part of the security deposit. |
| Hawaii | Capped, plus a separate pet deposit or fee | Hawaii caps a security deposit at one month's rent, plus an optional pet deposit of up to one more month's rent — never for an assistance animal kept as a reasonable accommodation. |
| Iowa | Capped by state law | Iowa caps a security deposit at two months' rent. |
| Kansas | Capped, plus a separate pet deposit or fee | Kansas caps a security deposit at one month's rent (one and a half months if furnished). If pets are allowed, the landlord may add a pet deposit of up to half a month's rent. |
| Maine | Capped by state law | Maine caps a security deposit at two months' rent. |
| Maryland | Capped by state law | Maryland caps a security deposit at one month's rent per unit, however many tenants there are. |
| Massachusetts | Capped by state law | At the start of a tenancy a Massachusetts landlord may collect only first month's rent, last month's rent, a security deposit of no more than one month's rent and the cost of a new lock — so a separate pet deposit is not allowed. |
| Michigan | Capped by state law | Michigan caps a security deposit at one and a half months' rent. |
| Missouri | Capped, plus a separate pet deposit or fee | Missouri caps a security deposit at two months' rent, but the statute's definition of a security deposit excludes a pet deposit — so a pet deposit is not counted toward the cap. |
| Nebraska | Capped, plus a separate pet deposit or fee | Nebraska caps a security deposit at one month's rent, plus a pet deposit of no more than a quarter of a month's rent. |
| Nevada | Capped by state law | Nevada caps the total of security deposit and surety bond, including last month's rent, at three months' rent. |

| New Jersey | Capped by state law | New Jersey caps security for a rental home at one and a half months' rent. |
| New Mexico | Capped by state law | New Mexico caps a deposit at one month's rent for leases shorter than a year. On annual leases there is no cap, but a deposit above one month's rent earns the tenant interest. |
| New York | Capped by state law | New York caps any deposit or advance at one month's rent (seasonal rentals aside), so a pet deposit has to fit inside that one month. |
| North Carolina | Capped, plus a separate pet deposit or fee | North Carolina caps a security deposit at two weeks' rent (week-to-week), one and a half months (month-to-month) or two months (longer leases). A landlord may also charge a reasonable, nonrefundable pet fee. |
| North Dakota | Capped, plus a separate pet deposit or fee | North Dakota caps a security deposit at one month's rent. A separate pet deposit may not exceed $2,500 or two months' rent, whichever is greater — and cannot be charged for a service or assistance animal. |

| Rhode Island | Capped by state law | Rhode Island caps a security deposit, however it is labelled, at one month's rent (with an extra furniture deposit allowed for furnishings worth $5,000 or more). |

| Virginia | Capped by state law | Virginia caps a security deposit, however it is labelled, at two months' rent. |
