Residential Zoning Pet Limits in Maryland: What You Need to Know
July 1, 2026
If you live in Maryland and want to know how many pets you can legally keep at your address, the answer almost never comes from a single state law. Maryland spreads that authority across counties, municipalities, zoning codes, and private agreements — meaning the rules at your neighbor’s house in the next county can look entirely different from yours.
Understanding where those rules come from, and how they layer on top of each other, is the fastest way to stay on the right side of the law. This guide walks through every level of the system, from the absence of a statewide cap all the way down to HOA fine schedules and how to look up your specific address.
Pro Tip: Always check at least three sources before assuming you know your pet limit: your county animal control code, your municipal ordinance if you live in an incorporated city or town, and your lease or HOA governing documents.
Does Maryland Have a Statewide Pet Limit?
Maryland does not set a statewide cap on the number of pets a household can own. Maryland is among the 36 states that do not set a statewide limit on the number of dogs a household can own. The same is true for cats and most other companion animals — there is no single Maryland statute that says “no more than X pets per residence.”
What Maryland state law does address is the point at which pet ownership crosses into commercial kennel territory. Under Maryland Local Government Code §13-108, a person must obtain a kennel license from the local licensing agency if they own or have custody of six or more unspayed female dogs over the age of six months kept for the purpose of breeding and selling their offspring, or if they sell dogs from six or more litters in a year. That threshold is a commercial trigger, not a residential pet limit.
Maryland is unique in that state law governs the specific licensing and other regulations that certain counties may adopt or enforce. Counties can build on — or go beyond — that state framework, which is exactly what most of them do. If you want to know your actual pet limit, you need to look at the local level.
For comparison, you can see how neighboring states handle this question in our guides on residential zoning pet limits in New York and residential zoning pet limits in New Jersey.
How Residential Zoning Affects Pet Limits in Maryland
Zoning is the primary mechanism through which Maryland communities control how many animals you can keep and what types are permitted. Your zoning classification — whether you are in a single-family residential district, a multi-family zone, an agricultural overlay, or a rural county — determines which animal rules apply to your property.
Some counties allow limited boarding in residential areas with restrictions on the number of animals and outdoor exercise. However, the general rule across most Maryland jurisdictions is that commercial kennel operations belong in agricultural, commercial, or industrial zones — not standard residential districts. That same zoning logic also shapes how many pets a homeowner can keep before triggering a kennel license requirement.
The distinction between residential and agricultural zoning matters enormously for pet owners. Many counties either prohibit certain animals entirely in residential zones or require a minimum lot size before any livestock can be kept. For example, Baltimore County’s zoning regulations specify a minimum of three acres for stabling and keeping livestock. Residential pet limits, by contrast, tend to focus on dogs and cats rather than livestock, but the same zoning-first logic applies.
Each Maryland city may also impose its own building, noise, or land-use restrictions for animal-related uses, especially those operating from residential properties. Some areas require minimum lot sizes, enclosed exercise yards, or soundproofing to reduce barking disturbances, while others limit how many animals can be kept on-site before a commercial license is required.
Key Insight: Your zoning district classification is the starting point for every pet limit question. Before consulting any other source, confirm your zoning designation through your county’s online property portal or planning department.
Dog and Cat Limits in Maryland by City and County
Because Maryland delegates pet limit authority to its 23 counties and Baltimore City, the numbers vary widely across the state. Below is a summary of how several major jurisdictions approach dog and cat limits in residential settings.
| Jurisdiction | Dog Limit (Residential) | Cat Limit | Notes |
|---|---|---|---|
| Baltimore County | 3 before kennel license required | No stated cap | 4+ dogs require holding facility or kennel license |
| Hagerstown (Washington County) | 5 | Check local code | 6+ dogs require kennel zoning eligibility |
| Montgomery County | No hard numeric cap | No hard numeric cap | Nuisance and sanitary conditions rules apply |
| Howard County | No hard numeric cap | No hard numeric cap | Licensing, leash, and welfare rules enforced |
| Garrett County | 5 before kennel classification | 5 before kennel classification | Kennel license required for 5+ dogs or cats |
| Anne Arundel County | No stated numeric cap | No stated numeric cap | Dog licensing mandatory; exotic/wild animals prohibited |
In Baltimore County, if you have more than three dogs, you are required to obtain a holding facility or kennel license. That threshold effectively sets a soft residential cap at three dogs for most homeowners who do not want to pursue a commercial license.
If you live within Hagerstown city limits, you are not allowed more than five dogs, so kennel licensing in that area will not apply. Washington County’s unincorporated areas use a different process: you must visit the Washington County Division of Plan Review and Permitting and request a letter for a kennel license — that letter must state whether you are zoned to have six or more dogs.
In Garrett County, a kennel is defined as an establishment wherein any person, group of persons, or corporation engages in the business of boarding, breeding, buying, or selling dogs or cats, or wherein at any one time there are kept or harbored five or more dogs or cats. That means keeping five or more dogs or cats at a single address in Garrett County crosses into kennel territory regardless of whether you are running a business.
Montgomery County takes a different approach. Rather than setting a hard numeric cap, county code prohibits owners from allowing an animal to cause an unsanitary, dangerous, or offensive condition because of the size or number of animals kept in a single location or because a facility is not appropriate for the animal or properly maintained. In practice, this means you could be cited for too many pets even without a specific number being written into the ordinance.

Limits on Other Pets in Maryland
Beyond dogs and cats, Maryland regulates other animals through a combination of state wildlife law, county ordinances, and public health codes. The rules depend heavily on the species involved and where you live.
Exotic and Wild Animals
Maryland’s approach to exotic pets is built on a layered framework of criminal statutes, wildlife regulations, and public health codes that work together — and sometimes overlap. The primary statute governing this is Maryland Criminal Law § 10-621, which sets out a list of specifically prohibited species and the conditions under which permits may be issued for others.
At the county level, restrictions can be even stricter. In Anne Arundel County, a person may not keep or permit to be kept on the person’s premises any wild animal, exotic animal, or vicious animal as a pet or for display or exhibition purposes. Small animals such as hamsters, gerbils, guinea pigs, mice, rats, other small rodents, rabbits, ferrets, birds, fish, and nonpoisonous amphibians and reptiles are not considered wild animals or exotic animals under this rule. The keeping of skunks, raccoons, and opossums is illegal in Anne Arundel County.
Howard County is similarly restrictive: wild or exotic animals are not permitted as pets, and this category includes the offspring of domesticated animals bred with a wild or exotic animal.
Reptiles and Amphibians
Maryland requires a Captive Reptile and Amphibian Permit from the Department of Natural Resources for many native and non-native species. If you hold a valid Captive Reptile and Amphibian Permit, you may possess an unlimited number of animals from the permitted lists that are captively produced or legally obtained from out of state, with proper documentation — far beyond the four-individual limit that applies to unpermitted keepers. There is a $10.00 annual fee charged for the Captive Reptile and Amphibian Permit, which is valid from the date of issuance until the following December 31.
Birds
Indoor pet birds generally face no numeric cap in Maryland residential zones. However, outdoor aviaries are regulated. In Montgomery County, an owner must not allow a domestic or exotic bird, including a homing pigeon, to be in an aviary within 100 feet of any structure (other than the owner’s home) used for human habitation or work. This does not apply to a bird inside the owner’s dwelling, in a pet shop, or in an agricultural area.
Backyard Poultry
Chickens occupy a separate regulatory category from companion animals. There is no statewide limit on hens or coops, but all poultry owners must register with the Maryland Department of Agriculture (MDA) — even for one or two birds — to track diseases like avian flu. Local limits vary widely: urban areas often limit flocks to four to eight hens with permits and no roosters; suburbs and rural zones are more permissive.

HOA and Landlord Pet Rules in Maryland
Even if your county ordinance does not set a hard pet limit, your homeowners association or landlord may impose one. These private agreements operate on top of — not instead of — local law, and they can be significantly more restrictive.
HOAs in Maryland are generally permitted to adopt pet policies that are more restrictive than county ordinances. A common example is a two-pet maximum written into CC&Rs (covenants, conditions, and restrictions), even in a county that has no numeric cap in its animal control code. HOA pet rules are contractual obligations, not just suggestions. Violating them can lead to fines or legal action by the association, even if you are fully compliant with county animal control laws.
Maryland law also reinforces HOA authority in a specific way. Maryland law makes clear that HOA common areas are not treated as the owner’s property for animal control purposes. As noted under Montgomery County’s code, the common area of a homeowner’s association, condominium, or cooperative is not the owner’s premises — meaning a cat roaming into shared HOA space can legally be considered at large, even if it never leaves the broader development.
For renters, the picture is shaped by your lease. Maryland landlords can set rules and costs for pets, but these rules come with legal limitations to help protect renters. In Maryland, landlords are allowed to charge “pet rent” — an additional monthly fee for keeping a pet in your rental home. There is no statewide law that sets a maximum cap for pet rent, so landlords can set the amount, as long as it is clear in your lease agreement.
One important protection for renters: by law, landlords cannot charge pet rent or deposits for service or assistance animals required for a disability. That rule applies regardless of what the lease says about pets generally.
Important Note: If you live in a condominium or co-op, check both the association’s bylaws and the board’s most recent pet policy resolution. Boards can update pet rules between major governing document revisions, so the original CC&Rs may not reflect the current limit.
How to Find the Pet Limit Where You Live in Maryland
Because Maryland’s pet limits are set at the local level, there is no single lookup tool that covers the entire state. You will need to work through a short checklist to find the rules that apply to your specific address.
- Identify your zoning classification. Most Maryland counties offer an online property portal where you can enter your address and see your zoning designation. Baltimore County’s My Neighborhood portal and similar tools in Montgomery and Howard counties are good starting points.
- Read your county’s animal control ordinance. Search your county’s name plus “animal control ordinance” or check Municode (municode.com), which hosts the codified ordinances for most Maryland jurisdictions. Look for sections on “number of animals,” “nuisance animals,” or “kennel license thresholds.”
- Check your municipality’s code if applicable. Local municipal ordinances can add yet another layer. Cities and towns within Maryland counties sometimes have their own animal control rules that differ from the county baseline. If you live within an incorporated city or town, check both the county ordinance and your municipality’s code.
- Review your HOA or lease documents. Pull your CC&Rs, condo bylaws, or rental lease and search for “pet,” “animal,” or “number of pets.” If the document is unclear, contact your HOA management company or landlord directly and ask for the current written policy.
- Contact your county animal control office directly. For county-specific rules, contact your local animal control office directly. Each county administers its own ordinances, and the people in those offices can tell you exactly what is and is not permitted in your jurisdiction.

Penalties for Exceeding Pet Limits in Maryland
The consequences for keeping more pets than your zoning or ordinance allows depend on which layer of the rules you have violated. Civil fines, criminal charges, and forced removal of animals are all possible outcomes, depending on the jurisdiction and the severity of the situation.
County Animal Control Penalties
At the county level, most violations start with a civil citation. Violators of animal control laws in Howard County may be issued civil citations with monetary penalties of $25 to $500. Criminal penalties can include up to three years in prison and a $5,000 fine, pet impoundment, and/or mandatory appearances before the Animal Matters Hearing Board.
Montgomery County uses a tiered fine structure for animal control violations. The common area of a homeowner’s association, condominium, or cooperative is not the owner’s premises, and violations such as allowing an animal to be at large carry a $100 fine for the first offense and a $500 fine for each subsequent violation.
Zoning Violations
If you are keeping animals in a zone that does not permit them — for example, running an unlicensed kennel in a single-family residential district — the penalties escalate beyond animal control fines. Zoning violations related to keeping animals illegally on a residential property can result in stop-use orders requiring you to remove the animals. Repeat or unresolved violations can also result in civil court action by the county.
State-Level Violations
Violating Maryland’s state dog statutes carries its own penalties. A person who violates the state subtitle governing dogs is guilty of a misdemeanor and on conviction is subject to imprisonment not exceeding 30 days or a fine. This applies to situations such as operating without a required kennel license at the state threshold.
HOA and Landlord Penalties
If you exceed the pet limit set by your HOA or lease, the association or landlord can pursue remedies under the contract rather than through animal control. These typically include written warnings, recurring fines, and — in the most serious cases — eviction proceedings or legal action to enforce the covenant.
Pro Tip: If you receive a citation from animal control, you generally have the right to contest it. In Howard County, for example, you can appeal within 15 days of the citation being issued. Check your specific county’s ordinance for the exact timeline and process.
