Why Pet Policies Matter More Than Ever

Pet ownership has surged across Europe and North America over the past decade. In the UK alone, an estimated 57% of adults own a pet. In Spain, cats and dogs now live in roughly one in three households. Yet housing laws have struggled to keep pace with this reality: millions of pet owners face the prospect of choosing between a home and their companion animal every time they need to move.

Understanding the legal landscape — and knowing how to negotiate effectively within it — can make a decisive difference. The rules differ markedly between countries and sometimes between cities within the same country, so it is essential to know the framework that applies to you specifically.

Spain: Ley de Arrendamientos Urbanos and Pet Clauses

In Spain, residential tenancies are governed principally by the Ley 29/1994, de 24 de noviembre, de Arrendamientos Urbanos (LAU), as amended most recently in 2023. The LAU does not include any provision that grants tenants the right to keep pets. Consequently, landlords retain the right to prohibit animals in the rental property by including a no-pets clause (cláusula de prohibición de animales de compañía) in the lease agreement.

If a tenant moves a pet into the property in violation of such a clause, the landlord has grounds to initiate termination of the tenancy (resolución del contrato) under Article 27 of the LAU. Courts have generally upheld these clauses, though enforcement requires a judicial process.

However, the situation has a nuance following Spain's Ley 17/2021 on animal welfare. That law reclassified pets as sentient beings rather than objects, and some legal commentators argue that blanket contractual prohibitions may eventually be challenged as disproportionate. To date no definitive judicial precedent has emerged on this point, and landlords' contractual rights to prohibit pets remain broadly intact.

Practical advice for tenants in Spain: if a lease already contains a no-pets clause, negotiate its removal or modification before signing — once signed, the clause is enforceable. If the lease is silent on pets, the position is less clear; obtaining the landlord's written consent is strongly advisable.

United Kingdom: The Model Tenancy Agreement 2021

The UK government introduced the Model Tenancy Agreement in January 2021 as a template for landlords letting properties in England. One of its key provisions was a change to the default position on pets: under the Model Tenancy Agreement, landlords who want to refuse a tenant's request to keep a pet must do so in writing and with valid justification — such as the property being too small for the stated animal, or the building's lease prohibiting pets.

This was a deliberate policy shift. Previously, blanket no-pets clauses were standard, and tenants bore the burden of convincing landlords to make exceptions. The 2021 model inverted the presumption: pets should be allowed by default unless there is a specific, articulable reason to refuse.

Critically, the Model Tenancy Agreement is not legally mandatory — it is a government template that landlords may choose to adopt. Many private landlords and letting agents continue to use older agreements with standard no-pets clauses. The Renters (Reform) Act, which has been progressing through Parliament, is expected to give statutory backing to pet-friendly defaults, though the legislative landscape was still evolving as of mid-2026. Tenants in England should check whether their specific tenancy uses the Model Agreement or an older format.

In Scotland and Wales, separate tenancy frameworks apply; neither has adopted the Model Tenancy Agreement, though similar tenant-protection measures exist.

United States: A Patchwork of State and Local Rules

The United States has no federal statute granting renters the right to keep pets. The Fair Housing Act (FHA) is the closest federal framework, but it applies only to disability-related accommodations — service animals and, in some cases, ESAs — not to pets generally. Outside those protected categories, the decision to allow or prohibit pets is left to landlords, subject to state and local law.

A handful of states have passed tenant-friendly pet provisions. Oregon and California have enacted limitations on the size of pet deposits. Some cities, including San Francisco, have ordinances that restrict landlords from discriminating against pet owners in certain contexts. But across most of the United States, a landlord can lawfully refuse to rent to any tenant who has a pet, or can charge additional fees specifically for the presence of animals.

Pet Deposits and Pet Rent: What Is Legal

Two financial instruments are commonly used by landlords to manage the additional risk posed by pets: pet deposits and pet rent.

A pet deposit is a one-time refundable sum paid at the start of the tenancy, held against pet-caused damage. In most U.S. states, pet deposits are legal but are capped (often as a percentage of monthly rent or an absolute dollar limit). In California, the total of all deposits — including pet deposits — cannot exceed two months' rent for unfurnished properties. In the UK, the Tenant Fees Act 2019 effectively limits the total deposit to five weeks' rent (six weeks for higher-value properties), meaning landlords cannot charge a separate pet deposit on top of the main deposit without breaching the cap.

Pet rent is a recurring monthly surcharge added to the base rent. This is common in the U.S. and increasingly seen in the UK. Unlike a deposit, pet rent is non-refundable and simply increases the overall cost of the tenancy. It is generally legal unless prohibited by local ordinance, and landlords are not required to justify the amount charged.

In Spain, there is no specific legislation on pet deposits; any additional deposit or surcharge would be governed by general tenancy and consumer contract rules, and any amount beyond two months' rent (for standard residential tenancies) may be challengeable.

How to Negotiate a Pet-Friendly Lease

Even when facing a landlord who is initially reluctant, tenants with pets have several effective negotiating tools:

• Pet CV / Pet Resume: A one-page document for the animal that includes age, breed, weight, training certificates, vaccination records, and character references from previous landlords. This demonstrates responsibility and reduces the landlord's perceived risk.
• References from previous landlords: A written statement from a prior landlord confirming there was no pet-related damage carries significant weight.
• Pet liability insurance: Offering to purchase and maintain insurance that covers pet-caused damage (or third-party liability) addresses the landlord's financial concerns directly.
• Offering an increased deposit or pet addendum: Proposing a reasonable additional deposit specifically for pet damage — within legal limits — signals good faith.
• Pet addendum to the lease: A written pet addendum naming the specific animal, its vaccination status, and behavioural expectations can reassure landlords who are concerned about undefined future risk.

Service Animals and Emotional Support Animals: Different Rules Apply

Service animals — animals trained to perform specific tasks for a person with a disability — are not legally classified as pets in most jurisdictions and cannot be excluded by a no-pets clause. In the United States, the Americans with Disabilities Act (ADA) and the Fair Housing Act require landlords to make reasonable accommodations for both service animals and, under the FHA specifically, emotional support animals (ESAs) with proper documentation.

In the UK, the Equality Act 2010 requires landlords to make reasonable adjustments for disabled tenants, which can include permitting an assistance animal. In Spain, Ley 3/2023 on animal welfare affirms the rights of users of assistance animals in public and private spaces, though residential tenancy applications require case-by-case analysis.

If you rely on a service animal or ESA for a documented disability, consulting a disability rights organisation or solicitor before approaching a landlord will clarify your specific legal protections and how to invoke them correctly.
