County noise ordinances: quiet hours and limits by county

We cover 28 county noise ordinances in 8 states. Where a county's rules apply differs: some cover only areas outside city limits, others the whole county, and each page says which. 3 counties rely mainly on decibel limits, 18 mix decibel limits with an audibility test, and 7 use audibility or nuisance alone, including Harris and Bexar in Texas, which have no county noise ordinance at all.

Counties added since late October show here without a link for a few weeks while we measure how their pages are found; their pages are live and linked from the city and county list.

State law above the counties

Where a county sets nothing, or nothing for the noise you have, state law is what remains. We explain it for Texas, Florida, California, Ohio, New Jersey and Colorado.

Does a county noise ordinance apply inside city limits?

It depends on the county. Some county codes cover only the unincorporated areas outside any city or town, others reach the whole county, and some let a city's own ordinance take over where the two conflict. Each county page says which applies there, quoted from the county code.

What if my county has no noise ordinance?

Then state law applies. Harris County and Bexar County in Texas have no county noise ordinance that we could find, so their pages explain the Texas state law that applies. Nassau County, New York leaves noise to its towns, villages and cities.

How do I find my county's noise rules?

Search the county's official code (Municode, eCode360, American Legal Publishing or the county's own site) for "noise", and check whether you live inside a city or town, whose ordinance may apply instead. The county pages here link the exact code they quote.

Dealing with a noise problem?

The free online decibel meter measures the level where you are (nothing is recorded or uploaded), and apartment quiet hours covers what a lease can add. These are plain-language summaries, not legal advice; each county page links the official code.
