Why It Matters
Your pet policy is one of the most consequential decisions you make as a landlord. Allow pets with no rules and you risk carpet damage, odor remediation costs, and neighbor complaints. Prohibit pets entirely and you screen out a large share of the qualified tenant pool — around 70% of U.S. renters have at least one pet. The practical middle ground is a clear, enforceable policy that defines exactly which animals are permitted, what fees apply, and what happens if a tenant violates the terms. Done right, a well-structured pet policy turns a potential liability into a competitive advantage: pet-owning tenants tend to stay longer, pay on time, and have fewer options than tenants without pets — which means lower vacancy rates for you.
At a Glance
- What it is: Written rules governing animals in rental units — species, breeds, sizes, fees, and tenant obligations
- Common components: Pet deposit (refundable), pet fee (non-refundable), monthly pet rent, weight or breed restrictions
- Typical pet rent: $25–75/month per pet; pet deposits commonly run $200–500 per animal
- Who it affects: All tenants — even no-pet policies must exempt service and emotional support animals under federal fair housing law
- Key legal boundary: Landlords cannot charge pet deposits or pet rent for service animals or ESAs
How It Works
The three revenue tools in a pet-friendly policy. Most landlords combine one or more of three mechanisms: a refundable pet deposit (held like a security deposit, returned minus documented damage), a non-refundable pet fee (one-time charge at move-in), and monthly pet rent (ongoing income added to base rent). Many states cap or regulate security deposits — check whether pet deposits fall under your state's security deposit ceiling before setting amounts. Monthly pet rent sidesteps most deposit regulations and creates recurring revenue that partially offsets wear-and-tear costs over time.
What the policy should cover in writing. A complete pet policy addresses: the number of pets allowed per unit, approved and excluded species, weight or size limits (common thresholds: 25 lbs or 50 lbs), breed restrictions if applicable, vaccination and license documentation requirements, tenant liability for pet-caused damage, noise and nuisance standards, and the process for requesting approval of a new pet mid-tenancy. Vague policies create disputes. If your policy says "small dogs allowed" without a weight limit, you have no enforceable basis to decline a 60-pound pit bull when a tenant argues it's "small."
Service animals and ESAs are a legal carve-out. Under the Fair Housing Act, landlords must make reasonable accommodations for tenants with disabilities who rely on service animals or emotional support animals (ESAs). These are not pets under the law — you cannot charge pet deposits or pet rent for them, and you cannot apply breed or weight restrictions. You can require documentation (a letter from a licensed mental health or medical provider for ESAs; for service animals, you may ask only whether it is trained to perform a specific task). A no-pet policy does not exempt you from this requirement. Violating it exposes you to HUD complaints and civil liability.
Breed and size restrictions: proceed carefully. Many landlords exclude certain dog breeds — pit bulls, Rottweilers, Dobermans — based on perceived liability or insurance requirements. Check your landlord insurance policy first: some carriers will cancel or exclude coverage for specific breeds. However, blanket breed bans applied to service animals are illegal, and some cities and states restrict breed-based policies altogether (Denver ended its pit bull ban in 2020). Know your local ordinances before writing breed exclusions into your lease.
Real-World Example
Dante owns a four-unit apartment building in Columbus, Ohio. When he bought it, the previous owner had a strict no-pets policy. Dante had 60-day vacancies averaging two per year, and tenant turnover every 14 months. He decided to test a pet-friendly policy on the two ground-floor units, which had direct outdoor access.
He wrote a pet addendum allowing up to two cats or one dog under 40 lbs, with a $300 non-refundable pet fee per animal and $50/month in pet rent. He required current vaccination records within 30 days of move-in and added a clause stating that damage beyond normal wear and tear attributable to pets would be deducted from the security deposit. Both pet-friendly units leased within three weeks — compared to 45-day average for the no-pet units. Average tenancy in those two units stretched to 26 months. Dante now earns an extra $100–200/month in pet rent, has had one carpet replacement in three years (cost: $800, covered by the pet fee collected), and attributes the lower vacancy to the reduced competition tenants face in a market where most landlords still say no.
Pros & Cons
- Attracts a larger, often more loyal tenant pool — roughly 70% of U.S. renters have pets and face limited options
- Pet rent and pet fees generate incremental revenue that partially offsets wear-and-tear costs
- Pet-owning tenants tend to sign longer leases and renew more often, reducing vacancy and turnover costs
- A written policy creates enforceable standards and protects you legally if pet-related damage occurs
- Pets cause measurable property damage — carpet staining, odor, scratched floors, and yard wear require budgeting for higher turnover costs
- Landlord insurance premiums may increase or certain breeds may void coverage entirely
- Fair housing compliance adds complexity — service animals and ESAs require careful handling regardless of your policy
- Enforcing violations (unauthorized pets, exceeding weight limits) requires documentation and often formal notice processes
Watch Out
Verbal permissions create legal exposure. If you tell a tenant their cat is fine but never put it in writing, you have no fee structure, no documented permission, and no basis for charging damage costs later. Every animal that lives in your unit should be covered by a signed addendum — even if you waive the fee as a goodwill gesture, document it.
"No pets" doesn't protect you from ESA requests. The most common mistake among no-pet landlords is refusing ESA accommodation requests outright. HUD has made clear that landlords with no-pet policies must still evaluate and generally approve ESA requests with proper documentation. Flat refusals — particularly in writing — are routinely cited in fair housing complaints. When in doubt, consult a local landlord-tenant attorney before denying any accommodation request.
Pet fees are not universally legal. Several states and cities restrict or prohibit non-refundable pet fees, or require that all deposits — including pet deposits — be held in trust and returned with an itemized accounting. California, for example, caps total security deposits (including pet deposits) at two months' rent for unfurnished units. Know your state's rules before you structure your fee system.

The Takeaway
A pet policy is not a binary choice between allowing all animals and allowing none. It is a risk management tool that, when written clearly and enforced consistently, lets you capture a wider tenant pool, generate additional income, and protect your property. Build your policy around specific species, sizes, fees, and documentation requirements. Carve out service animals and ESAs as a legal non-negotiable. And get every animal on paper before a tenant moves in — not after you find out there's a dog.
