How we research and source our pages

Each city page is taken from that city's own code and from the city's official pages. The page names the code section and links to it.

Near the top, the page gives the date we checked the city's code and website. At the bottom, under the source links, that same date is shown as "Last checked."

Some state pages have a short section on state law. We add that section only after we have read the official statute or an official page published by the state. If we have not read it, the page says it doesn't cover that state's law.

We don't guess a rule the code doesn't state.

This is not legal advice. Laws change, so check the linked code before you act.

The home page looks up the quiet hours and the phone number from those city pages. The city quiet hours table lists the same quiet hours. You can download the same rows as a CSV file. Every city page is on the cities list. If a line is wrong, tell us on the contact page.

The 60-city quiet hours page counts those same lines. It says how many pages have no general quiet hours, which night window shows up most, which pages say to call 911, and how the construction notes compare.

City code links open the city's published code. Many are on Municode or American Legal. Some are on the city's own website, and a few cities use a different code site. Links to state law open the official state site.
