San Antonio Laws: Pets, Noise, Property, and Citations

San Antonio city ordinances are the local rules the City Council passes under the city’s home-rule charter, and they reach further into daily life than many residents expect: how tall your grass can be, when you can run a sprinkler, how loud your Saturday party can get, and whether the dog in your yard needs a microchip.¹ All of them live in a single document, the City of San Antonio Code of Ordinances, organized by chapter and published through the Municode Library.² Where Texas state law gives cities room to go further, San Antonio often does, and the fines escalate fast for people who find out the hard way.

Pets and Animals

Chapter 5 covers animals, and San Antonio enforces it more aggressively than many Texas cities. Every dog, cat, and horse must have a registered microchip implanted before the animal turns four months old.³ The city also caps the number of pets a household can keep and requires a permit to go over that limit.⁴

Letting a dog roam off your property is one of the most common citations. The first offense costs $100. The second is $500. Every offense after that runs $750. Animal Care Services can also spay or neuter a roaming dog before returning it to the owner.⁴

If Your Dog Is Declared Dangerous

A dangerous-dog designation triggers a separate list of requirements most owners don’t anticipate. You must carry at least $100,000 in liability insurance specifically covering injuries caused by the dog, kept in force for as long as you own the animal. The dog must live in a locked enclosure that keeps children out and the dog in, clearly marked, with weather protection.⁵

Outside the enclosure, the dog must be on a leash no longer than four feet and muzzled at all times. You also have to post at least two warning signs visible from the street, spay or neuter the dog at your own expense, finish a responsible pet ownership class within two months, and allow Animal Care Services to inspect your home each year to verify compliance. Missing any of these can get the dog seized.⁵

Noise Limits

Chapter 21 sets the noise rules. The ceiling in a residential area is 63 decibels measured at a neighboring property line, roughly the level of normal conversation a few feet away.⁶ Music, parties, and barking dogs are the usual triggers.

A standard noise violation carries a fine between $100 and $500. If the city can show the violation was intentional or reckless, the range for a first offense jumps to $100 to $2,000. A second intentional violation starts at a $200 minimum, and a third or later conviction starts at $300.⁶

Construction Hours

Construction follows its own schedule: 7:00 AM to 8:00 PM Monday through Friday, 8:00 AM to 8:00 PM on Saturday, and 9:00 AM to 5:00 PM on Sunday. No construction is permitted on six holidays: New Year’s Day, Memorial Day, Independence Day, Labor Day, Thanksgiving, and Christmas.⁷ Even inside those hours, construction noise cannot exceed 80 decibels at the property boundary.⁶

Property Upkeep

The property maintenance code gives the city real authority over how private property looks and functions, and enforcement moves faster than most owners expect.

Grass and Weeds

Vegetation on your property cannot exceed 12 inches within 150 feet of a curb line or neighboring property line. A notice of violation gives you 10 days to cut it down. Miss that deadline and you can face an administrative hearing citation carrying a fine between $300 and $1,000. On vacant lots the city can send its own contractor and bill the owner for the mow plus an administrative fee.⁸

Two situations skip the 10-day notice entirely: a vacant lot within 1,000 feet of a school or registered day care with vegetation over 48 inches, or an owner who was already notified of the same violation in the past 12 months.⁸

Graffiti

San Antonio treats graffiti as a public nuisance and requires property owners to remove it within 10 days of notice, though the city director can extend that window. If an owner refuses the city’s offer to remove it at no charge, a written notice gives 15 more days. After that, the city can remove it and bill the owner or place a lien on the property.⁹

This rule does not apply to residential owner-occupied properties or to commercial properties with an active, ongoing business. It targets vacant and absentee-owned buildings.⁹

Junked Vehicles

A vehicle that has been inoperable for 10 consecutive days and is visible from a public street, a neighboring property, or the first floor of a nearby building qualifies as a junked vehicle. Inoperable means the vehicle can no longer serve its intended purpose, whether or not it could theoretically be repaired. A wrecked or partially dismantled vehicle is presumed inoperable, and a tarp does not remove it from “ordinary public view.”¹⁰

The city has to give at least 10 days’ notice to the registered owner, any lienholders, and the property owner before removal. During that window you can request a public hearing in writing. Maintaining a junked vehicle is a misdemeanor carrying fines up to $200 for a first offense and a minimum of $100 for each later conviction, and each day the violation continues counts as a separate offense.¹⁰

Trees on Your Property

You cannot remove a large tree without a permit. The city classifies trees with a trunk diameter of at least 6 inches (measured 4.5 feet above the ground) as significant, and trees of 18 inches or more as heritage trees.¹¹

Removal of either requires a Tree Removal Permit and an arborist report identifying species, size, and health. Heritage trees carry the strictest mitigation: every inch of trunk diameter removed must be replaced at a 1:1 ratio in new plantings, or paid into the city’s Tree Mitigation Fund. For significant trees, mitigation can be satisfied by replanting on-site, replanting off-site, or a fee-in-lieu payment.¹¹

Short-Term Rentals

If you rent out a property or even a single room for fewer than 30 consecutive days, San Antonio classifies it as a short-term rental and requires a permit. Applications go through the Development Services Department’s online portal, and permits renew annually.¹²

Operators also have to collect and remit the city’s 7% Hotel Occupancy Tax on every booking.¹³ Texas imposes a separate 6% state hotel occupancy tax on top of that, so the total tax on each stay comes to 13%. The property has to meet safety standards including smoke alarms, carbon monoxide detectors, and fire extinguishers, and you need to designate a local contact who can respond to complaints or emergencies.

Water Use

Water conservation carries more weight in San Antonio than in most American cities. The San Antonio Water System (SAWS) enforces year-round watering rules tied to the Edwards Aquifer level, with four drought stages that progressively tighten the limits.

Under year-round rules, when the aquifer sits above 660 feet, you can water with a sprinkler or irrigation system any day of the week, but only between midnight and 10:00 AM or 9:00 PM and midnight. At 660 feet (Stage 1), sprinkler use drops to once per week on your designated day, during those same hours. Stage 2 (650 feet) narrows the morning window to 5:00 AM through 10:00 AM. Stage 3 (640 feet) holds the once-weekly limit with the same narrower hours. Stage 4, declared at the City Manager’s discretion, cuts watering to once every other week.¹⁴

A first residential violation runs $137, and you can get it waived by completing a one-hour online course. Repeat violations cost more. In Stage 3 and Stage 4, SAWS adds a drought surcharge of $10.37 per thousand gallons on single-family accounts using more than 20,000 gallons per month, with that threshold dropping to 12,000 gallons in Stage 4.¹⁴

Driving and Handheld Devices

San Antonio passed a hands-free ordinance in 2010 that prohibits using a handheld mobile device while driving, with fines up to $200 per violation. Texas later enacted a statewide texting ban, but the San Antonio rule is broader because it covers all handheld use, not just texting.

If You Get a Citation

Most local ordinance violations route through the San Antonio Municipal Court. You generally have three options: pay the fine, contest it at a hearing, or ask for an alternative resolution.

Deferred disposition works like probation. You plead no contest or guilty, pay court costs and a special expense fee that can run as high as the original fine, and the court sets a probation period. Stay violation-free through that period and the case is dismissed with no conviction on your record. Not every violation qualifies.¹⁵

For moving traffic violations, you may be able to take a state-approved defensive driving course instead of taking a conviction. To qualify, you need a valid Texas driver’s license, proof of insurance, and no defensive driving dismissal in the 12 months before the offense. You have to submit the request on or before your appearance date, pay the required court costs, and finish the course within 90 days.¹⁵

If you cannot pay in full, go to Municipal Court at 401 S. Frio Street and ask for a hearing on your ability to pay or a payment plan. The court also handles some citation resolutions online.¹⁶ Ignoring the citation is the one option that makes everything worse: unpaid fines turn into warrants and added fees that cost far more than the original violation.
