Houston noise ordinance: quiet hours, limits and complaints

Last updated: August 11, 2026

Quiet hours in Houston

Houston does not impose a flat curfew on noise at night. Instead, the code defines "nighttime hours" as 10:01 p.m. to 7:59 a.m., and during those hours the decibel ceiling for sound arriving at a residential property drops from 65 dB(A) to 58 dB(A) (Sec. 30-1, Sec. 30-5(a)(1)). The limit for sound arriving at a nonresidential property stays at 68 dB(A) around the clock, day and night. Construction is handled separately and indirectly: Sec. 30-16(5) makes it an affirmative defense that construction or demolition noise occurred between 7 a.m. and 8 p.m. and stayed at or below 85 dB(A) at the receiving residential property line, so construction outside 7 a.m. to 8 p.m. has no such defense and is judged against the ordinary 65/58 dB(A) limits. The same 7 a.m. to 8 p.m. window and 85 dB(A) ceiling applies to lawnmowers, saws, drills, sanders, grinders and similar tools used for property upkeep (Sec. 30-16(7)). Separately, a commercial establishment within 300 feet of a residential property needs a commercial establishment permit to run amplified sound after 10 p.m. Sunday through Thursday and after 11 p.m. Friday and Saturday. That trigger is not limited to outdoor speakers: Sec. 30-8(b) reaches both sound amplification equipment used in any outdoor area of the premises and indoor amplified sound that can be heard or appreciated beyond the establishment's property lines. Even with the permit, from 2 a.m. to 8 a.m. on any day the establishment may not run amplified sound in an outdoor area or let indoor amplified sound be heard beyond its property lines (Sec. 30-9(a)(4)b).

Decibel limits

Houston sets real numeric limits, measured at the property line of the property RECEIVING the sound, aimed back toward the source (Sec. 30-5(a)). Because Houston has no zoning, the limits turn on whether the receiving property is residential or nonresidential rather than on a zoning district. Residential receiving property: 65 dB(A) during daytime hours (8 a.m. to 10 p.m.) and 58 dB(A) during nighttime hours (10:01 p.m. to 7:59 a.m.). Nonresidential receiving property: 68 dB(A) at all times. Sound amplification equipment operated under a daily, extended daily, annual or commercial establishment permit may reach 75 dB(A) during that permit's authorized hours (Sec. 30-9(a)); a commercial establishment permit's late-night block (10 p.m. to 2 a.m. Sun-Thu, 11 p.m. to 2 a.m. Fri-Sat) drops back to the ordinary Sec. 30-5 levels rather than 75 dB(A). Three defense thresholds also carry numbers: construction and demolition 85 dB(A) at the residential property line between 7 a.m. and 8 p.m. (Sec. 30-16(5)); powered saws, drills, sanders, routers, grinders, lawn and garden tools and lawnmowers 85 dB(A) on the same 7 a.m. to 8 p.m. schedule (Sec. 30-16(7)); air conditioning units 65 dB(A) at residential property or 75 dB(A) at nonresidential property (Sec. 30-16(9)). Measurement must use a Type 1 or Type 2 calibrated sound level meter, A-weighting, slow response, ANSI S1.4-1984/85A, with a windscreen (Sec. 30-6). These are the only decibel figures in the chapter: a full sweep of Chapter 30 returns 58, 65, 68, 75 and 85 dB(A) and nothing else.

What the ordinance actually says

Sec. 30-5(a): "In addition to the violations established in other sections of this chapter, it is unlawful for any person to make, assist in making, permit, continue, cause to be made or continued, or permit the continuance of any sound beyond the property lines of the property on which the sound is being generated that exceeds the applicable dB(A) level listed below for the property on which the sound is received when measured from the property line of the residential or nonresidential property receiving the sound towards the source of the sound: (1) Residential property: a. 65 dB(A) during daytime hours. b. 58 dB(A) during nighttime hours. (2) Nonresidential property: 68 dB(A) at all times."

Sec. 30-1 (Definitions): "Daytime hours means the hours between 8 a.m. on one day and 10 p.m. the same day." and "Nighttime hours means the hours between 10:01 p.m. on one day and 7:59 a.m. the following day."

Sec. 30-2(a): "It is unlawful for any person to make, assist in making, permit, continue, cause to be made or continued, or permit the continuance of any loud, unnecessary, or unusual sound or noise that disturbs, injures, or endangers the comfort, repose, health, peace, or safety of others."

Sec. 30-6: "Whenever portions of this chapter prohibit sound over a certain decibel limit, measurement shall be made with a Type 1 or Type 2 calibrated sound level meter utilizing the A-weighting scale and the slow meter response as specified by the American National Standards Institute (A.N.S.I. S1.4-1984/85A)."

Sec. 30-16(5): "The sound was produced by the erection, excavation, construction, or demolition of any building or structure, including the use of any necessary tools or equipment, conducted between the hours of 7 a.m. and 8 p.m., which activity did not produce a sound exceeding 85 dB(A) when measured from the property line of the residential property where the sound is being received."

Sec. 30-16(7): "The sound was produced by operating or permitting the operation of any mechanically powered saw, drill, sander, router, grinder, lawn or garden tool, lawnmower, or any other similar device used between the hours of 7 a.m. and 8 p.m., provided the device did not produce a sound exceeding 85 dB(A) when measured from the property line of the nearest residential property where the sound is being received and was used for the maintenance or upkeep of the property on which it was operated."

Sec. 30-7(a): "It is unlawful for any person to make, assist in making, permit, continue, cause to be made or continued, or permit the continuance of any sound using any sound amplifier that is part of or connected to any speaker system, radio, stereo receiver, compact disc player, cassette tape player, microphone, computer or other sound source in a vehicle that, when operated disturbs the peace, quiet, and comfort of the neighboring inhabitants, or is plainly audible at a distance of 50 feet from the vehicle from which the sound is emanating."

Sec. 30-1 (Definitions): "Plainly audible when describing a sound or noise means any amplified sound or noise that can be clearly heard by a person with normal hearing faculties such that a reasonable person would believe such sound or noise unreasonably disturbs, injures, or endangers the comfort, repose, health, peace, or safety of others in violation of this chapter. The term does not require the clear appreciation of specific words of speech or specific words of a song."

Sec. 30-5(b): "Regardless of the measurable dB(A) level established in this chapter and measured in a manner provided in subsection (a) of this section, the creation of any sound causing persons occupying or using any property other than the property upon which the sound is being generated to be aware of vibrations or resonance caused by the sound shall be prima facie evidence of a sound that unreasonably disturbs, injures, or endangers the comfort, repose, health, peace, or safety of others in violation of this chapter."

Sec. 30-3: "The keeping of any animal or bird that causes or makes frequent or long and continued sound that unreasonably disturbs, injures, or endangers the comfort, repose, health, peace, or safety of ordinary, reasonable persons of normal sensibilities and ordinary tastes, habits, and modes of living who reside in the vicinity thereof is hereby prohibited and declared to be unlawful regardless of whether the sound so created by said animal or bird is within the permissible levels specified in section 30-5 of this Code."

Sec. 30-2(c): "The provisions of this chapter shall not apply to a food service establishment or the establishment's sound-related activity under and limited to the express parameters identified in section 437.029 of the Texas Health and Safety Code."

Sec. 30-17(a): "Any person who violates any provision of this chapter, including but not limited to a violation of any provision or condition of a permit issued pursuant to this chapter, is guilty of an offense and, upon conviction thereof, shall be punished by a fine not to exceed $2,000.00. Each hour or portion thereof in which any violation shall occur shall constitute a separate offense."

How to file a noise complaint in Houston

Call the Houston Police Department non-emergency line at 713-884-3131. HPD enforces Chapter 30 and will send an officer to take a meter reading from the complainant's own receiving property line toward the source. The City's own Chapter 30 briefing lists three other avenues for noise and sound complaints: the online alert slip form at houstontx.gov/police/alert_slip/, in person at a community meeting hosted by your local police station, and by mail to the Office of the Chief of Police, 1200 Travis Street, 16th floor, Houston TX 77002. Houston 311 (dial 311, or 713-837-0311, staffed 24/7) is the general city service line and can route a request, but the city's published guidance for Chapter 30 noise points to HPD, so calling HPD directly is the faster route. Questions about sound amplification permits, including whether a bar or venue actually holds one, go to the Administration and Regulatory Affairs department rather than HPD. Use 911 only for an actual emergency.

Worth knowing

Measured from YOUR property line, not the source. Sec. 30-5(a) takes the reading at the property line of the property receiving the sound, aimed toward the source, so a complainant stands on their own lot to establish the violation. No zoning, so no zoning-district table. Houston has no conventional zoning ordinance, and the limits split only between residential and nonresidential receiving property. Vibration is its own trigger. Under Sec. 30-5(b), feeling bass vibration or resonance inside your home is prima facie evidence of a violation even if the meter reads under the limit, which matters for nightclub and car-audio complaints. Construction hours are a DEFENSE, not a permission. Sec. 30-16(5) and (7) do not authorise construction or lawn equipment between 7 a.m. and 8 p.m.; they give the defendant an affirmative defense if the work stayed inside that window and under 85 dB(A) at the residential property line. Outside those hours the ordinary 65/58 dB(A) limits govern. Vehicle stereos use a plainly-audible test. Sec. 30-7 needs no meter: amplified sound plainly audible 50 feet from the vehicle is enough, and Sec. 30-1 expressly provides that plainly audible does not require the clear appreciation of specific words of speech or of a song. Animals and rattling vehicles bypass the meter entirely. Secs. 30-3 and 30-4 apply "regardless of whether the sound so created" is within the Sec. 30-5 levels. Permit regime run by a different department. The Administration and Regulatory Affairs department issues four permit classes (daily, extended daily, annual, commercial establishment) letting amplified sound reach 75 dB(A) in authorised hours, while the Houston Police Department does the enforcement. The commercial establishment permit is mandatory for a food-or-drink business within 300 feet of a residential property that runs amplified sound after 10 p.m. Sun-Thu or 11 p.m. Fri-Sat, and it reaches indoor sound heard beyond the property line as well as outdoor-area speakers; from 2 a.m. to 8 a.m. both are barred outright. State-law preemption carve-out, recently added. Sec. 30-2(c), added by Ord. No. 2025-742 on 27 Aug 2025, switches off the whole chapter for a food service establishment's sound-related activity within the parameters of Tex. Health and Safety Code sec. 437.029, a state statute that limits how cities may regulate food service establishment noise. Broad list of defenses. Sec. 30-16 also exempts stadium events, permitted parades, amphitheatre events, city-sponsored festivals and races, fireworks displays inspected by the fire marshal, aircraft and railroads, air conditioners under 65/75 dB(A), religious observance during daytime hours capped at five cumulative minutes per hour, and daytime activity in public parks, playgrounds and school grounds. One-minute drafting gap. Daytime ends at 10 p.m. and nighttime begins at 10:01 p.m., leaving a literal sliver between the two defined periods, and the same occurs between 7:59 a.m. and 8 a.m. Nothing turns on it in practice: the Sec. 30-2 general prohibition on loud, unnecessary or unusual noise applies around the clock regardless of the Sec. 30-5 numbers. Penalty escalates fast: up to $2,000 per offense, and each hour or part of an hour is a separate offense (Sec. 30-17).

Document it before you report it

Houston's limits are measured numbers, so a reading is direct evidence of how loud it really is. Take a quick reading with the free online decibel meter — it runs in your browser and records nothing — and check how loud your block is on the Houston noise map. For time-stamped measurement history you can show a landlord or code officer, the app keeps a log.
