Building construction can occur during the hours of 7:00 AM to 8:00 PM, seven days a week, including holidays.  Any work done before or after these hours must not exceed the noise level of five decibels at the nearest lot line unless a special permit has been granted to allow this.  Five decibels is similar to the sound of a screw gun installing screws in drywall. This is detailed in Police Code Article 29, Sections 2907 and 2908.  Construction related noise complaints can be directed to the Department of Building Inspection, Inspection Services at (415) 558-6570. Construction related complaints beyond the allowed hours should be directed to your local police station.
