Building construction can occur 7:00 am to 8:00 pm seven days a week, including holidays.
Noise is expected during daytime construction, but cannot exceed five decibels above ambient at the nearest lot line before 7 am or after 8 pm. Five decibels is similar to the sound of a screw gun installing screws in drywall.
Some construction is allowed at night
Only construction projects with a night noise permit can do outdoor construction outside before 7 am or after 8 pm. This occurs for public safety, building structural integrity, or traffic and road access issues.
