How Houston Handles Noise from Specific Sources: A Practical Guide
Houston maintains 186 local ordinances across all categories, and 4 of those deal specifically with noise from specific sources. Here is a breakdown of what the city actually requires, what is prohibited, and where Houston falls on the strict-to-permissive spectrum compared to other cities.
Low-Frequency Bass Limits
Houston bans sound that makes neighbors feel vibrations or resonance, even when it stays under the chapter's dB(A) limits: the rule that reaches thumping bass and subwoofers.
Key details: Governing section: Code of Ordinances § 30-5(b). Trigger: Vibration or resonance felt off-property. dB(A) meter reading: Irrelevant if vibration is felt. Maximum fine: $2,000 per violation. Enforcing agency: Houston Police / ARA Department.
A citation carries a fine up to $2,000 per violation under § 30-17, with each hour of continuing violation counted as a separate offense; enforced by Houston police and the Administration and Regulatory Affairs Department.
Car Alarm Limits
Houston's burglar-alarm permit article, Chapter 11, expressly excludes vehicle alarms: Section 11-50 says the article covers burglar, holdup, and panic alarms but "not audible alarms affixed to motor vehicles," and Section 11-51 excludes an "alarm installed in a motor vehicle solely to prevent theft" from the permit definition. A blaring car alarm is instead handled under the general noise ordinance.
Key details: Alarm-permit exclusion: Chapter 11 excludes audible motor-vehicle alarms by name. Governing sections: Code of Ordinances Sections 11-50 and 11-51. Permit needed?: No permit required for a car alarm. Fallback rule: General noise chapter (Sec. 30-4, 30-5) applies instead. Enforcement contact: Houston Police Department, not the alarm-permit office.
There is no alarm-permit fine for a car alarm, since Chapter 11's permit and false-alarm fee scheme excludes motor-vehicle alarms by name. A car alarm that disturbs neighbors instead falls under the general noise chapter: sound exceeding the residential limits in Section 30-5, or a vehicle sound source cited under Section 30-4, is enforced through the same citation and penalty structure as any other Chapter 30 noise violation.
The rules around car alarm limits in Houston lean permissive, but that does not mean anything goes.
Bar & Nightclub Noise
Bars and nightclubs within 300 feet of a home need a City sound permit to run amplified music past 10 or 11 p.m., and all outdoor sound cuts off at 2 a.m.
Key details: Trigger distance: Within 300 ft of a home. Cutoff without permit: 10 p.m. Sun-Thu, 11 p.m. Fri-Sat. Hard cutoff (even permitted): 2 a.m. to 8 a.m.. Max fine: $2,000 per hour. Issuing agency: Admin & Regulatory Affairs director.
Fine up to $2,000 per violation; each hour of continuing violation is a separate offense. Permits can be suspended up to 180 days or revoked, with a one-year wait before reapplying.
Compared to other cities, Houston takes a harder line on bar & nightclub noise. The enforcement and penalty structure reflects that.
HVAC & Mechanical Noise
Under Houston's noise ordinance, an air conditioning unit that stays at or below 65 dB(A) on residential property or 75 dB(A) on nonresidential property is a legal defense to a Chapter 30 noise citation.
Key details: Residential AC cap: 65 dB(A) at property line. Nonresidential AC cap: 75 dB(A) at property line. Legal status: Affirmative defense, not a proactive limit. Max fine: $2,000 per hour of violation. Enforcing agency: Administration and Regulatory Affairs Department.
Violating Chapter 30's noise limits is a misdemeanor punishable by a fine up to $2,000, with each hour of continuing violation a separate offense.
The Bottom Line
Houston's noise from specific sources 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 Houston is broadly strict or permissive.
Keep in mind that Houston can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
