What to Know About Renting to Tenants with Service Animals

Key Takeaways

-Assistance animals are legally protected: Service Animals and Emotional Support Animals (ESAs) are protected under the Fair Housing Act (FHA), requiring landlords to reasonably accommodate them regardless of pet policies.

-Landlords still retain their rights: Landlords can request verification of a tenant’s disability and enforce behavioral and safety standards, but must avoid intrusive questions and unreasonable denials.

-Compliance is attainable: Update leases, train staff, document communications, and handle requests professionally with the help of an experienced property manager to ensure compliance and reduce legal risks.

For many Massachusetts landlords, navigating pet policies feels simple until a tenant requests a service animal or emotional support animal. At that point, the personal occupancy rules give way to the Fair Housing Act (FHA), under which these animals are no longer considered pets and must be treated in accordance with strict legal standards.

In a state with strong tenant protections and active enforcement of landlord-tenant law, understanding how to respond correctly to assistance animal requests is essential to protecting both your property and your liability. Handled improperly, even a well-intentioned response can trigger complaints or legal exposure. 

Handled well, it reinforces professionalism, reduces risk, and encourages long-term leases. Our team at J. Butler Property Management has in-depth local experience in this arena, so we’ve put together an article to guide new and seasoned property investors alike.

What Qualifies as an Assistance Animal in Housing

There are two legitimate types of assistance animals where housing law is concerned: Service Animals and Emotional Support Animals. 

Service Animals

Service animals, typically dogs, are trained to perform specific, disability-related tasks. Examples include guiding individuals with vision impairments, alerting someone to seizures, assisting with mobility, or interrupting panic episodes.

Their defining feature is task-specific training, not certification or registration.

Emotional Support Animals (ESAs)

Emotional Support Animals, or ESAs, differ in important ways:

–They do not require specialized task training

–They provide therapeutic or emotional support related to a disability

–Animals other than dogs may be considered ESAs (within reason)

Despite these differences, ESAs receive the same housing protections under the FHA as service animals, provided the request is legitimate.

Why Assistance Animal Rules Deserve Special Attention in Massachusetts

Massachusetts consistently ranks among the most tenant-protective states in the country. Housing law here emphasizes access, fairness, and nondiscrimination, and assistance animal requests sit squarely at the intersection of those priorities.

Three foundational principles govern assistance animal situations:

-Assistance animals are not pets under federal housing law. Pet policies, pet fees, breed restrictions, and animal caps generally do not apply.

-A “no pets” policy does not override a valid accommodation request. Even buildings marketed as pet-free must consider service animals and ESAs.

-Landlords still retain the right to protect property safety, habitability, and operations. Accommodation does not mean surrendering standards.

For owners of multifamily buildings, condominiums, or older housing stock common across Massachusetts, clarity on these rules is essential. Enforcement agencies do not expect perfection, but they do expect good-faith compliance backed by consistent procedures.

The Legal Foundation: FHA and ADA Explained Simply

Two federal laws shape how assistance animals are governed, and understanding the difference between them prevents confusion when it comes to understanding how you must treat tenant requests.

The Fair Housing Act (FHA)

The Fair Housing Act (FHA) governs residential housing nationwide. Under this law, landlords must provide reasonable accommodations for tenants with disabilities. That obligation includes both service animals and emotional support animals, even when animals are otherwise prohibited.

In housing, the FHA is the primary authority landlords must follow.

The Americans with Disabilities Act (ADA)

The ADA applies to public accommodations, not private housing. It covers only service animals, typically dogs trained to perform specific tasks, and does not extend protection to ESAs.

This distinction explains why ESAs may be protected in apartments but not permitted in grocery stores or restaurants.

For Massachusetts landlords, the practical takeaway is simple:

–Service animals are protected under FHA and ADA.

–Emotional support animals are protected under FHA only.

Housing decisions in particular hinge on the FHA, as well as any other local or state regulations.

What Massachusetts Landlords Are and Aren’t Allowed to Ask

One of the most common landlord worries when it comes to FHA compliance is saying the wrong thing. The safest approach is knowing exactly where the legal line is drawn. 

What You May Request

Landlords may request reliable verification that:

–The tenant has a qualifying disability

–The animal provides support related to that disability

This verification typically comes in the form of a brief letter from a licensed healthcare or mental-health professional.

What You May Not Request

Landlords may not ask for:

–Medical records or treatment history

–Details about the diagnosis or severity of the disability

–Proof of training, certification IDs, or online registrations

–Excessive forms or invasive questionnaires

Massachusetts fair housing enforcement places particular emphasis on avoiding unnecessary intrusion.

Where Landlords Still Retain Control

Accommodating an assistance animal does not mean losing authority over your property. Owners still maintain important rights.

Behavioral and Safety Standards

If an assistance animal damages the unit, acts aggressively, creates sanitation issues, and disrupts other tenants, you may address the behavior through standard lease enforcement. Accommodation protects access, not misconduct.

Health and Licensing Requirements

Landlords may require reasonable health and safety measures, such as compliance with local licensing laws, vaccination records, and parasite prevention. These requirements must be applied consistently and not used as a pretext for denial.

Limited Grounds for Denial

A request may be denied only in narrow circumstances:

–The animal poses a direct threat that cannot be mitigated

–The accommodation creates an undue financial or administrative burden

–The provided documentation is clearly fraudulent or unverifiable

Because these situations are scrutinized closely in Massachusetts, we strongly advise seeking legal guidance before denying any accommodation request made by tenants with disabilities.

Best Practices for Massachusetts Property Owners

Responsible landlords treat disability accommodation compliance as part of operational discipline, not a one-off exception. 

Here are some ways to integrate these practices into your baseline operations:

-Update lease language to reflect current fair housing law so that your expectations are clear and aligned with the law. Absolute “no animals under any circumstances” clauses are outdated and risky.

-Train anyone interacting with tenants, such as leasing agents, office staff, or maintenance teams, on how to handle accommodation requests appropriately.

-Document all communication about assistance animals carefully. Clear records demonstrate good-faith compliance if questions arise.

-Approach requests with professionalism and empathy. Respectful handling often reduces conflict and improves tenant retention.
