An emotional support animal is protected in housing only if its behavior does not pose a direct threat, cause significant property damage, or create an ongoing nuisance. ESA letters do not excuse aggression, poor hygiene, or repeated disturbances. Housing protections under federal law are conditional on responsible animal behavior.
Emotional support animals exist to support mental health, but housing protection is never unconditional. The most common reason ESA accommodations fail is not paperwork. It is behavior.
Under federal housing law, an ESA can live in housing with no-pet policies only if the animal does not threaten safety, damage property, or interfere with other residents’ rights. Many renters discover this too late, often after complaints, warnings, or formal notices arrive.
Key Takeaways
-
ESA housing protection depends on behavior, not just a valid letter
-
Landlords may remove an ESA that poses a direct threat or ongoing nuisance
-
ESA status does not reduce owner liability for injuries or property damage
-
Training and medical care protect housing rights, not just pet manners
-
ESA letters document need, not animal behavior or temperament
What the Law Actually Requires of ESA Behavior
Federal housing law protects emotional support animals only when they can live safely and reasonably within a shared residential environment. An ESA that creates danger, damage, or repeated disruption can legally lose its accommodation.
Housing protections for ESAs come primarily from the Fair Housing Act and interpretive guidance from the U.S. Department of Housing and Urban Development. These laws require landlords to make reasonable accommodations for tenants with disabilities. Reasonable does not mean unlimited.
A landlord is not required to accommodate an animal if doing so would create:
-
A direct threat to the health or safety of others
-
Substantial physical damage to property
-
An unreasonable interference with other residents’ quiet enjoyment
ESA behavior is evaluated individually. Breed, size, and species are not automatic disqualifiers. Conduct is.
The Reasonable Accommodation Standard Explained
A reasonable accommodation is one that allows a tenant equal access to housing without imposing undue burden on the property or other residents. For ESAs, this creates a balance between disability rights and shared living standards.
Behavioral expectations under this standard include:
-
The animal remains under control
-
The animal is housebroken and sanitary
-
The animal does not engage in aggressive or destructive behavior
-
The animal does not repeatedly disturb others
If these conditions are not met, the accommodation may no longer be considered reasonable.
Behaviors That Can Legally Invalidate an ESA Accommodation
An emotional support animal may lose housing protection if its behavior creates safety risks, causes property damage, or results in ongoing disturbances that violate lease standards applied to all tenants.
Behavior issues that affect ESA accommodations typically fall into three legally meaningful categories.
1. Safety-Related Behavior
Safety concerns carry the most immediate legal consequences. Examples include:
-
Biting or attempting to bite a person
-
Lunging, snapping, or charging at others
-
Repeated growling directed at residents or staff
-
Attacking other animals on the property
Landlords may act when there is objective evidence of risk. A single verified bite incident may be sufficient. Decisions must be based on documented behavior, not fear or assumptions.
2. Property Damage and Sanitation Issues
An ESA must be able to live in a residential setting without causing health or sanitation problems. Examples include:
-
Urinating or defecating indoors
-
Repeated marking behavior
-
Chewing or destroying doors, walls, flooring, or fixtures
-
Persistent odors or hygiene issues affecting shared spaces
-
Flea or parasite infestations that spread beyond the unit
Housebreaking is a baseline requirement. An animal that cannot reliably maintain basic sanitation can be excluded regardless of ESA status.
3. Nuisance Behavior
Nuisance behavior is one of the most common reasons ESA accommodations are challenged.
Examples include:
-
Excessive or uncontrolled barking
-
Scratching or pawing at doors and walls repeatedly
-
Running loose in hallways or common areas
-
Preventing neighbors from sleeping, working, or using shared spaces
Occasional noise is normal in residential living. Patterned, documented disruption is not.
Housebreaking and Sanitation Rules
An emotional support animal must be housebroken to qualify for housing protection. Repeated indoor accidents are a valid legal basis for accommodation denial or removal.
Housebreaking is not optional. It is one of the most consistently enforced standards in ESA disputes.
Landlords are not required to tolerate:
-
Indoor waste accidents
-
Uncontrolled marking behavior
-
Sanitation issues affecting shared spaces
An ESA that cannot reliably eliminate outdoors places a health burden on the property. That burden makes the accommodation unreasonable under housing law.
Navigating Different Environments with Your ESA
Your animal’s behavior is judged differently depending on the setting. What is acceptable at home may not be appropriate in an office or during travel.
Behavior in Public and at Work
It is a common misconception that ESAs have the same access rights as service animals. For a full breakdown of the difference between ESAs and service dogs, see our guide. Under the ADA, only service animals (typically dogs trained to perform specific tasks) are allowed in public places like restaurants and stores. ESAs do not have these protections.
Workplaces are a different story. Under Title I of the ADA, allowing an employee to bring an ESA to work can be considered a reasonable accommodation. If you make such a request, your employer can set behavior standards. The animal would likely need to stay near your workstation, be leashed, and not disrupt coworkers. Any aggression or significant distraction could result in the accommodation being revoked.
Handling Stressful Environments and Travel
Stress is a major trigger for emotional support animal behavior issues. Crowded spaces, loud noises, and unfamiliar environments can cause even a well behaved animal to act out. An anxious animal might pant, pace, or even growl as a sign of distress.
Travel is particularly stressful. This is one reason the Department of Transportation changed its rules in 2021; airlines are no longer required to accommodate emotional support animals in the cabin. The change was largely due to numerous incidents of untrained ESAs acting out on planes, from barking and lunging to soiling the cabin. If you plan to travel with your animal, prepare ahead of time by bringing familiar items and consulting your vet about calming aids, and review international airline and country rules.
Proactive Solutions for ESA Behavior Problems
The best way to handle emotional support animal behavior issues is to prevent them from starting. A proactive approach focused on training and wellness is key.
The Importance of Training and Socialization
Unlike service dogs, ESAs are not required to have any specialized training. Do emotional support animals need training? Here’s what to know. This makes it your responsibility to ensure they have good manners. A lack of basic obedience training and socialization is the root cause of many common problems like jumping, pulling on the leash, and excessive barking. Studies show that dogs who miss out on early socialization are at a higher risk of developing fear and aggression issues later in life. Investing in basic obedience classes can make a world of difference for you and your ESA.
Consulting a Veterinarian
If your ESA suddenly develops a behavior problem, your first call should be to a veterinarian. Here’s how to find a good veterinarian. Many behavioral changes are caused by underlying medical issues. A dog might become aggressive because it is in pain from an ear infection or arthritis. A vet can rule out or treat any medical causes. If the issue is purely behavioral, they can recommend a certified trainer, an animal behaviorist, or even prescribe anti anxiety medication to be used alongside a training plan.
Your ESA Letter and Your Responsibilities
Getting an ESA letter is the first step in securing your housing rights. Services like Emma & Buddy connect you with a licensed mental health professional to see if you qualify. This process is fast, confidential, and compliant with state and federal laws.
The Clinician’s Role (and What It Isn’t)
It is crucial to understand the role of the clinician who writes your letter. Their job is to evaluate your mental health and determine if you have a disability related need for an animal’s support. They are not evaluating your animal’s temperament or training. The clinician often never even meets your pet.
Your ESA letter is documentation of your need for the animal; it is not a certification of your animal’s good behavior. The responsibility for preventing emotional support animal behavior issues rests entirely with you, the owner.
Frequently Asked Questions About Emotional Support Animal Behavior Issues
1. Can my landlord evict me because of my ESA’s behavior?
Yes. If your ESA is a direct threat, causes significant property damage, or creates a nuisance (like nonstop barking) that violates the lease agreement for all tenants, a landlord can take action, which may include revoking the accommodation or starting eviction proceedings.
2. What is the difference between normal barking and a nuisance?
Occasional barking is normal for a dog. A nuisance refers to excessive, uncontrolled, and continuous barking that disturbs other residents, particularly during quiet hours. Documented complaints from multiple neighbors are often required for a landlord to act.
3. Does my emotional support animal need to be professionally trained?
No, there is no legal requirement for an ESA to have professional training. However, it is highly recommended. Basic obedience training and proper socialization are the best ways to prevent common emotional support animal behavior issues.
4. What should I do if my ESA is aggressive towards another person or animal?
You should immediately consult a veterinarian to rule out medical causes and then work with a certified professional dog trainer or veterinary behaviorist who specializes in aggression. This is a serious issue that needs expert intervention.
5. How can I prepare my ESA for a stressful situation like moving?
Gradually acclimate your pet to moving materials like boxes. Stick to a consistent routine for feeding and walks. On moving day, keep them in a quiet, secure room with familiar items like their bed and toys to reduce their anxiety. A calm owner can also help an animal feel more secure.
Your emotional support animal offers invaluable comfort, and your ESA letter secures their place in your home. By taking responsibility for their training and behavior, you ensure a peaceful and positive experience for everyone. If you’re ready to take the next step, start your ESA housing letter with Emma & Buddy to connect with a licensed professional and see if you qualify.
