Noise Monitoring in
Texas
Class 1 sound data for Texas's city and county noise codes.
Texas is building faster than almost anywhere in the country — semiconductor fabs and data centers across Central and North Texas, energy and petrochemical work on the Gulf Coast, and steady growth in Houston, Dallas–Fort Worth, San Antonio, and Austin. Texas has no single statewide construction-noise limit, so the rule that applies comes from the city or county, with a state penal-code backstop above it.
Specto equips Texas contractors and consultants with Class 1 monitoring stations that record around the clock, measure levels against the background, send alerts when a threshold is exceeded, and report automatically. Instead of assembling a system on site, your team installs a configured station and starts documenting conditions from day one — answering questions with data instead of recollection.
Regulatory
The Rules That Apply to Texas Projects
Texas has no comprehensive statewide construction-noise ordinance, but a state penal-code provision sets a backstop and each city writes its own rules, so the governing standard depends on where you’re working:
- Local ordinances set the limits — Texas cities and counties adopt their own noise codes, commonly holding residential areas near 65 dB(A) by day and 55 to 58 dB(A) at night at the receiving property line, many adding a "plainly audible" test and quiet hours from 10:00 p.m. to 7:00 a.m.
- Statewide backstop (Texas Penal Code) — noise is presumed unreasonable once it exceeds 85 dB after a person is notified by a peace officer or magistrate, a threshold several cities fold directly into their construction rules
- Houston (Code Chapter 30) — general construction and demolition is allowed from 7:00 a.m. to 8:00 p.m. and must not exceed 85 dB(A) at the nearest residential property, with lower limits for residential sound (about 65 dB(A) day and 58 dB(A) night) and stop-work authority for violations
- City-by-city variation — Dallas holds construction near homes to about 7:00 a.m.–7:00 p.m. and judges noise by "ordinary sensibilities" rather than a fixed decibel, San Antonio caps construction at 80 dB, Austin requires permits and on-site monitoring for after-hours and large work, and El Paso holds construction to 65 dB
- Federal and state rules — federal OSHA worker noise-exposure requirements (29 CFR 1926.52) and FHWA 23 CFR 772 apply, alongside TxDOT requirements and project-specific permit conditions
Why Texas Teams Choose Specto
01
Ready to Deploy: US Inventory
Specto stocks Class 1 noise monitoring systems in the US for rent or purchase. Teams in Houston, Dallas, San Antonio, Austin, Fort Worth, and El Paso can have monitoring on site in days — before a concern turns into a delay.
02
Field-Ready: Configured Before Shipment
Each station arrives with alert thresholds, reporting schedules, and SvanNET remote access already set. Your crew installs and starts recording, instead of assembling a system on site.
03
Applied Expertise: City-by-City Codes
A Texas threshold depends on the local ordinance, and limits, quiet hours, and construction rules differ between Houston, Dallas, San Antonio, and Austin. Specto configures each station to the standard governing your site — capturing the background level where it applies — with automated reports built for agency and community review.

The Texas Construction Landscape
Texas has become the center of the country’s semiconductor and AI buildout. Samsung’s $17 billion fab in Taylor — the largest foreign investment in state history — is coming online, Texas Instruments is expanding its Sherman campus, and Dallas–Fort Worth has become the second-largest data-center market in North America. Farther west, the flagship of the Stargate AI project near Abilene is finishing a roughly four-million-square-foot, eight-building campus, part of nearly $90 billion in data-center construction underway across the state — enough that Texas has begun pausing new approvals to study the strain on power and water.
Alongside the chips and data centers, the Gulf Coast keeps building refineries, petrochemical plants, and LNG export terminals; the Texas Medical Center and Port of Houston keep expanding; and TxDOT is rebuilding major corridors like I-35 through Austin. Much of this work happens close to homes, schools, and hospitals in some of the fastest-growing cities in the country, where noise draws quick attention — and continuous monitoring gives Texas teams the data to document conditions, respond to concerns, and keep work moving.

Our Methodology — How We Work With You
01
Discovery
We start by understanding the project, not by selling equipment. That means scope, timeline, and location; monitoring requirements and regulations; site constraints like power, connectivity, and access; and who needs the reports.
02
System Design and Preparation
We bring together the hardware, sensors, power and connectivity strategy, software setup, alerts, reporting, mounting, and accessories — then configure and prepare the system so it arrives ready for the field.
03
Delivery, Onboarding and Support
We support your team through deployment guidance, practical training, troubleshooting, reporting and alert support, and calibration and service coordination for the life of the project.
Texas Noise Monitoring — Common Questions
Not a single construction ordinance, but the Texas Penal Code presumes noise is unreasonable above 85 dB once someone is notified by a peace officer, and each city adds its own rules. Houston has among the most detailed — construction is allowed 7:00 a.m. to 8:00 p.m. and capped at 85 dB(A) at the nearest home — while Dallas, San Antonio, Austin, and El Paso each set different hours and limits. Because the governing rule depends on where you're working, confirm the specific ordinance for your site with the authority having jurisdiction.
Houston's Chapter 30 limits construction sound to 85 dB(A) measured from the nearest residential property, with lower limits overnight, and the state penal code uses the same 85 dB figure as a backstop. The SV 307A is a Class 1 station that records continuously, so you can document the level at the receiving property against that standard and answer a complaint or support a permit with data. Its built-in 4G modem sends SMS and email alerts the moment a level approaches the threshold, and data stays available through SvanNET for agency and community review.
Long deployments are where remote verification matters most. The SV 307A pairs a patented dual-microphone system check with a built-in sound source for manual or automated verification, so you can confirm the measurement path without a site visit, and data stays available through SvanNET for the life of the project. A built-in 4G modem sends SMS and email alerts the moment a threshold is exceeded.
