What does Colorado law say about noise?
- Home limits
- Colorado Revised Statutes § 25-12-103 says noise measured 25 feet or more from a property line can count as a public nuisance when it is over a set level. For a home, that level is 55 dBA from 7 a.m. to 7 p.m. and 50 dBA from 7 p.m. to 7 a.m.
- Exceptions
- The same section allows a short daytime peak of 10 dBA. That peak can last up to 15 minutes in an hour. Construction uses the industrial limits instead. Those are 80 dBA by day and 75 dBA at night, for the time on the permit.
