Animal Ordinances in Mountain View, CA

If you live in Mountain View or are thinking about moving there, animal ordinances are one of those things you probably won't think about until they affect you directly. Mountain View has 14 specific rules on the books covering different aspects of animal ordinances, and some of them might surprise you.

Beekeeping

Mountain View lets residents keep bees but fixes exact placement rules under City Code Sec. 5.46: a hive must sit at least 10 feet from a side or rear property line and at least 20 feet from any public road, and the beekeeper needs the landowner's written consent regardless of location. Moving an apiary into the city requires 5 days' written notice to the administrator.

Key details: Side/rear setback: 10 feet minimum from property line. Road setback: 20 feet from any public road. Move-in notice: Written notice within 5 days. Violation correction window: 48 hours after posted notice. Governing section: MVCC Sec. 5.44-5.49, Art. IV.

Placing a hive closer than the required setbacks, skipping the required move-in notice, or failing to post identification signage draws a notice of violation under Sec. 5.49, and failing to correct the problem within the 48-hour posting period is itself unlawful. Citations follow the citywide penalty schedule in Sec. 1.7: up to $100 for a first infraction, $200 for a second within a year, and $500 for a third, with a fourth in the same year chargeable as a misdemeanor.

Mandatory Spay/Neuter

Mountain View forces sterilization on any dog or cat impounded twice or more from the same owner over the animal's lifetime: City Code Sec. 5.37 requires the animal be spayed or neutered at the owner's expense before it can be redeemed from the shelter. Owners may choose their own veterinarian, though the impounding agency can require it handle transportation, and owners may request a hearing.

Key details: Trigger: 2nd impound of same unsterilized animal. Cost: Borne by the owner. Vet choice: Owner may use a private veterinarian. Appeal path: Hearing under Sec. 5.33. Governing section: MVCC Sec. 5.37.

An owner who redeems a twice-impounded, unsterilized dog or cat without complying with Sec. 5.37 remains subject to the impounding agency's hold on the animal until sterilization is completed or arranged, and the owner pays the veterinary cost regardless of which vet performs the surgery. Underlying impoundment violations, such as running at large, are separately penalized under the citywide schedule in Sec. 1.7, with fines escalating from $100 to $500 across repeat infractions in a year and a fourth chargeable as a misdemeanor.

This is not one of those rules that cities tend to ignore. Mountain View actively enforces its mandatory spay/neuter requirements.

Pet Store Rules

Mountain View bans displaying, offering or selling any animal anywhere except a permitted pet shop or kennel, or a private residence, under City Code Sec. 5.84. Pet shops also cannot sell a cat or dog younger than eight weeks, must give buyers vaccination and health disclosures, and cannot give a dog or cat away as a contest prize under Sec. 5.81 and 5.82.

Key details: Sale locations: Permitted animal facility or a private residence. Minimum age to sell: 8 weeks for a cat or dog. Immunization required: Before sale, per Sec. 5.82. Buyer return window: 5 days to have animal vet-examined. Minor buyers: Sale needs parent/guardian written permission.

Selling or displaying an animal outside a Sec. 5.66-permitted facility or a private residence violates Sec. 5.84. Selling a cat or dog under eight weeks old, skipping the required immunization or disclosure paperwork, or refusing a valid Sec. 5.83 return and refund, exposes the seller to code enforcement citation and, on the return claim, to a civil court action by the buyer for the purchase price.

Compared to other cities, Mountain View takes a harder line on pet store rules. The enforcement and penalty structure reflects that.

Chickens & Livestock

Mountain View bans keeping livestock in any R (residential) district and makes it unlawful to keep chickens, ducks, geese, turkeys, pigeons, or other fowl anywhere in the city except as Chapter 5, Article III allows, under City Code Sec. 5.38. Article III then caps most households at four animals total, bans roosters over four months old, and requires a permit for housing within ten feet of a property line.

Key details: Household animal cap: 4 total (may rise to 25 by permit). Roosters: Banned over 4 months old (non-commercial). Setback permit trigger: Housing within 10 feet of property line. Neighbor notice for expansion: Mailed 50-foot radius, 10-day comment window. Governing section: MVCC Sec. 5.38, Art. III.

Keeping livestock in an R district, exceeding the four-animal cap without an administrator exception, or keeping a rooster past four months old is a code violation enforced under the citywide penalty schedule in Sec. 1.7: up to $100 for a first infraction, $200 for a second within a year, $500 for a third, and a fourth within the year chargeable as a misdemeanor. The administrator can also revoke a Sec. 5.39 housing permit for noncompliance.

Pet Limits

Mountain View caps most households at four adult dogs and cats combined over four months old, and at only one unspayed female dog and one unspayed female cat, under City Code Sec. 5.51. A female is presumed unspayed unless the owner proves otherwise, and no more than one litter per year is allowed from animals on the property. Licensed vets, pet shops, and permitted kennels are exempt.

Key details: Combined dog/cat limit: 4 adults per street address. Unspayed female limit: 1 dog + 1 cat. Litter limit: 1 per calendar year. Exempt operations: Licensed vets, permitted kennels/shelters. Governing section: MVCC Sec. 5.51.

Keeping more than four dogs and cats combined, more than one unspayed female of each species, or more than one litter a year without qualifying for an exemption or a Sec. 5.75 rescuer registration is a code violation under the citywide schedule in Sec. 1.7: up to $100 for a first infraction, $200 for a second within a year, $500 for a third, and a fourth within the year may be charged as a misdemeanor.

Wildlife Feeding

Shoreline at Mountain View Park is declared a wildlife sanctuary by City Code Sec. 38.18(i), and feeding any wild bird, mammal, reptile, amphibian or invertebrate there is banned outright at all times, alongside hunting, trapping, killing or capturing them.

Key details: Governing section: City Code Sec. 38.18(i). Applies to: Shoreline at Mountain View Park only. Prohibited act: Feeding any wild bird, mammal, reptile. Research exception: City manager permit required. Domestic animal rule: Barred entirely, Sec. 38.9(w).

Feeding any wild bird, mammal, reptile, amphibian or invertebrate anywhere in Shoreline at Mountain View Park violates Sec. 38.18(i), as does hunting, trapping, killing, wounding, frightening or capturing that wildlife without a city manager research permit. Bringing a dog, cat or other domestic animal into Shoreline, other than a certified seeing-eye dog, separately violates Sec. 38.9(w). Park rangers hold arrest power under Sec. 38.19 through 38.21 to enforce these provisions.

This is one of the stricter rules in Mountain View's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Veterinary Clinic Zoning

Veterinary clinics fall under Mountain View's "animal service establishment" category. City Code Section 36.30.35 allows them in commercial and general industrial districts only with a conditional use permit, and requires them to control noise and odor and shelter animals out of public view.

Key details: Permit required: Conditional use permit. Allowed zones: CN, CS, CO, CRA, MM. Animal shelter visibility: Not visible from right-of-way. Care standard: Chapter 5 animal control. Parking requirement: 1 space per 200 sq ft.

A veterinary clinic or other animal service establishment operating without the required conditional use permit, or failing to control noise, odor, or animal shelter visibility as Section 36.30.35 requires, is a Chapter 36 violation. Section 36.58.80 makes it a misdemeanor under City Code Section 1.7, allows the city to abate it as a public nuisance under Chapter 25, and the conditional use permit can be revoked for continued noncompliance.

Cat Rules

Unlike dogs, cats in Mountain View are never required to carry a city license: City Code Sec. 5.53(b) makes cat licensing purely voluntary, letting an owner register a cat if they choose. Cats remain subject to the same running-at-large and public-nuisance rules that apply to other animals, and a voluntarily licensed cat still gets a metal tag or microchip record.

Key details: Cat license requirement: Voluntary, not mandatory. Dog license requirement (contrast): Mandatory at 4 months old. Nonresident dog exception: Under 30 days in 12 months. Show/exhibition exception: 10 days or less. Governing section: MVCC Sec. 5.53.

Because cat licensing is voluntary, failing to license a cat carries no penalty, but a cat that runs at large in violation of Sec. 5.2 or becomes a public nuisance under Sec. 5.11 can still be seized and impounded by an animal control officer. Underlying nuisance or at-large violations are penalized under the citywide schedule in Sec. 1.7: up to $100 for a first infraction, $200 for a second within a year, and $500 for a third, with a fourth chargeable as a misdemeanor.

If you are coming from a city with tighter rules, you will find Mountain View gives residents more flexibility on cat rules.

Microchipping

Mountain View lets a microchip substitute for the metal license tag, but only for cats. Dogs must still wear the metal "DOG/CAT LICENSE" tag issued with every license, per City Code Sec. 5.56. Every dog four months or older must be licensed, and the administrator records the microchip or tag number on the license.

Key details: Dog license age: Required at four months of age or older. Cat microchip: Optional; substitutes for the metal tag. Dangerous dog microchip: Mandatory under Sec. 5.64(a)(4). License term: 12-36 months for dogs; 60 for cats. Duplicate tag fee: Set by city council resolution.

Keeping an unlicensed dog past four months, letting a dog go without its metal tag, or transferring a tag to another animal violates Chapter 5 and is enforceable by citation from animal control officers or peace officers under Sec. 5.85, using the authority granted by Penal Code Sec. 836.5. A dog later declared dangerous that lacks the microchip, insurance and confinement Sec. 5.64 and 5.65 require can be seized, and the owner barred from keeping dogs for up to three years.

The rules around microchipping in Mountain View lean permissive, but that does not mean anything goes.

Pet Groomer Rules

Anyone who operates a pet grooming parlor in Mountain View needs an annual permit from the city's animal services administrator before opening, under City Code Sec. 5.66. Groomers must first secure any applicable zoning permit, then meet the housing, sanitation and animal-care conditions Sec. 5.68 imposes on every animal facility, subject to unannounced inspection.

Key details: Permit required: Annual permit from the animal services administrator. Prerequisite: Applicable zoning permit obtained first. Inspection: Administrator may inspect at any reasonable time. Permit term: 12 months, renewable; not transferable. Revocation trigger: 2+ convictions in 12 months or a cruelty conviction.

Operating a pet grooming parlor without the Sec. 5.66 permit, or failing to meet the housing, sanitation or care conditions in Sec. 5.68, is grounds for permit denial or revocation under Sec. 5.71, including for two or more Chapter 5 convictions within twelve months or any animal cruelty conviction in the prior five years. A revoked or denied applicant cannot reapply for six months under Sec. 5.73 unless the underlying problem is fixed.

Exotic Pets

Mountain View prohibits ownership of wild and exotic animals consistent with California Fish and Game Code, limiting residents to common domestic pets and certain small reptiles.

Key details: Governing law: CA Fish and Game Code. Ferrets: Illegal statewide. Big cats: Prohibited. Venomous reptiles: Prohibited. Enforcement: SVACA and CDFW.

Dog Leash Laws

Mountain View requires every dog owner to keep their dog on a leash no longer than six feet, or confined behind a fence of reasonable height, under City Code Sec. 5.50. Exceptions cover service animals, dogs in field or obedience trials, hunting or herding dogs, and dogs assisting a registered private patrol operator or peace officer. Posted off-leash areas allow up to two unleashed dogs per handler.

Key details: Leash length limit: 6 feet maximum. Off-leash area age minimum: 13 years old to supervise. Dogs per handler off-leash: 2 dogs maximum. Off-leash dog requirements: 4+ months old, licensed, vaccinated. Governing section: MVCC Sec. 5.50.

A loose or improperly restrained dog can be cited, and under Sec. 5.11 the animal control officer may seize and impound any dog creating a public nuisance. Fines follow the citywide schedule in Sec. 1.7: up to $100 for a first infraction, $200 for a second within a year, $500 for a third, and a fourth within the same year may be charged as a misdemeanor with fines and up to six months in jail.

Bird Protection

New buildings in Mountain View must treat most of their glass exterior with bird-friendly markers under City Code Sec. 8.96.10, part of the Green Building Code's mandatory Appendix A5 measures. At least 90 percent of a building's lower elevation and 60 percent of its upper elevation must use etched glass, patterned film, screens or similar strategies that break up reflective surfaces birds can strike.

Key details: Governing section: City Code Sec. 8.96.10, Appendix A5 Sec. A5.107.1. Lower elevation standard: 90% of elevation up to 40 ft treated. Upper elevation standard: 60% of elevation above 40 ft treated. Marker spacing rule: 2-inch max dot/stripe density (2 x 2 Rule). Applies to: New building elevations under Green Building Code.

A new building that installs untreated reflective or clear glazing across the required elevation percentages fails Sec. 8.96.10 review and will not pass the Building Division's plan check for the mandatory Appendix A5 measures. Because bird-safe glazing is a mandatory CALGreen measure rather than an optional one, the only way around the specific glazing product or barrier method is a written modification approved in advance under Sec. 8.64.20.

Breed Restrictions

California law bars Mountain View from banning or singling out any dog breed: Food and Agricultural Code Sec. 31683 lets cities run their own dangerous-dog program but forbids making it "specific as to breed." Mountain View's own dangerous-dog ordinance, Sec. 5.63 through 5.65, regulates individual dogs by documented behavior instead, regardless of breed.

Key details: State rule: No dog program may be breed-specific. Statute: Cal. Food & Agric. Code Sec. 31683. Local program: Behavior-based hearings, Sec. 5.63-5.65. Liability insurance: $100,000 minimum for a dangerous dog. Ownership ban: Up to 3 years after a dangerous designation.

A dog owner who fails to meet the microchip, muzzle, insurance or confinement conditions Sec. 5.64 and 5.65 impose on a dog already classified dangerous can have the animal seized and impounded, and faces citation under Penal Code Sec. 836.5 as applied by Sec. 5.85. There is no breed-based citation: a city ordinance that tried to restrict, license, or ban dogs by breed would itself violate Food and Agricultural Code Sec. 31683.

The rules around breed restrictions in Mountain View lean permissive, but that does not mean anything goes.

The Bottom Line

Mountain View's animal ordinances rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Mountain View is broadly strict or permissive.
