Live Oak FAQ
Does police need a decibel meter to write a ticket?
No. The plainly-audible standard lets officers cite based on what a reasonable person would hear at the property line.
Are the zoning dBA limits enforceable on residents?
They primarily govern industrial and commercial operations. Residential nuisance noise is handled via the general ordinance.
San Antonio FAQ
Who measures decibels in unincorporated Bexar County?
No one. The county does not have sound-metering enforcement. Deputies respond based on audibility and reasonableness under TX Penal Code 42.01.
Are motorcycle exhaust modifications legal in Bexar County?
Modifications are legal only if the vehicle does not exceed the sound produced when originally sold, per TX Transp Code 547.604. Straight-pipe or cutout exhausts typically violate this rule.
Can I use a phone app to prove a dBA violation in San Antonio?
Phone apps are useful for triage but generally not admissible. Chapter 21 enforcement uses a calibrated Type 1 or Type 2 meter operated by trained city staff.
