Construction noise: hours are not the same as quiet hours

The hours that apply to loud music at night often don't apply to a construction site. A city can ban loud music at 10 p.m. and still allow a job site to start at 7 a.m. Another city may exempt daytime construction from a decibel cap, then hold it to the normal cap at night.

The counts below come from the 60 city pages on this site. Each construction note is copied from that page. If the page does not state construction hours, the count says so. It does not guess.

The full table has the construction note for every city, with the code link. The 60-city count is the same tally, with night hours and 911 instructions next to it.

The hours work differently from city to city

Even among cities that list construction hours, the rules are not written the same way.

Some pages list the hours when work is allowed. Denver allows construction equipment that is plainly audible at a home from 7 a.m. to 9 p.m. Monday through Friday, and from 8 a.m. to 5 p.m. on Saturday and Sunday. The director can allow other hours in limited cases. See the Denver page.

Some pages list the hours when work is barred, or when it is presumed offensive. Dallas says construction on or next to a home is presumed offensive outside 7 a.m. to 7 p.m. Monday through Friday, and outside 8 a.m. to 7 p.m. on Saturdays and legal holidays. The page says the section does not list Sunday hours, so Sunday work next to homes falls outside the allowed windows. A written permit can cover other hours in urgent cases. See the Dallas page.

Fort Worth bars construction within 300 feet of an occupied home before 7 a.m. or after 8 p.m. on weekdays, and before 9 a.m. or after 8 p.m. on Saturday and Sunday. See the Fort Worth page.

Some pages do not ban the work at a set time. They exempt it from a decibel limit during a window. Anaheim exempts construction and building repair from the 60 dBA limit from 7 a.m. to 7 p.m. Outside those hours, the work has to meet the limit. See the Anaheim page.

Don't treat a 7 a.m. time as meaning the same thing in every city. In Denver, 7 a.m. on a weekday is when construction equipment may start. In another city, 7 a.m. may be when a ban ends. Read the sentence on the city page.

A state law can override the city hours

Phoenix's own code bars construction within 500 feet of an inhabited building outside set hours on non-holiday weekdays: 6 a.m. to 7 p.m. from May 1 through September 30, and 7 a.m. to 7 p.m. from October 1 through April 30. The city also describes a state law that took effect May 13, 2025. For permitted work from May 1 to October 15, that law allows Monday through Friday from 5 a.m. to 7 p.m., and Saturday from 7 a.m. to 7 p.m. Concrete can be poured up to one hour earlier. The city says it cannot use a noise rule to stop those summer hours when the job has a valid permit. See the Phoenix page and Arizona Revised Statutes § 9-500.52.

The city code still lists 6 a.m. as the summer start, but a 5 a.m. start can be legal in Phoenix in the summer if the job has a valid permit. The Phoenix after-hours line is 602-262-7456. The city says inspectors check for an after-hours permit first, and they need a number to call you back.

Honolulu's limit on construction noise is a state rule, not a city quiet hour for homes. The Hawaii Department of Health issues noise permits. Under HAR § 11-46-7(j), no permit allows construction noise over the limits before 7 a.m. or after 6 p.m. on weekdays, before 9 a.m. or after 6 p.m. on Saturday, or at any time on Sunday or a holiday. The Noise Section number on the Honolulu page is 808-586-4700. See the Honolulu page.

What to do when work starts early

Open the city page and read the construction sentences along with the night quiet hours. Check whether the rule is an allowed window, a ban, or an exemption from a decibel cap. Check Sunday, Saturday and holidays if the page mentions them. The count above already says how many construction notes mention Sunday or a weekend. On those pages, weekday hours are only part of the rule.

Write down the address, the date, the time you heard the work, and what the equipment was. If the city page names a permit, ask whether the job has one. Phoenix will not investigate an after-hours complaint if the inspector cannot reach you.

Then use the number that page gives for construction, if it has a separate one. If it does not, use the general noise number on the page. Most of these pages send ordinary noise to a non-emergency line. The 60-city count lists the pages that do say to use 911, and the reason each one gives.

If the work is at an apartment and your landlord hired it, tell the landlord in writing as well. The landlord guide is about a landlord who does not act. The letter guide has a short note and a landlord letter.

This is not legal advice. A permit, a holiday or an emergency repair can change the answer on a given morning. Read the code link on the city page before you treat a start time as a violation.
