Construction Noise Ordinances

Construction noise can be a big problem. Any noise complaints must be directed to the County level.

Montgomery County construction noise ordinances are as follows:
 

• Weekday hours of construction are 7:00am to 9:00pm.
• Weekend hours do not begin until 9:00am.
• The maximum acceptable level is 65 dBA for daytime and 55 dBA for nighttime.

This means that one can still lay carpet or undertake similar interior work after these hours unless the noise becomes as high as 65 dBA during the day and 55 dBA at night. The county has a machine used to measure noise levels but unless it is a continuous problem, it’s hard to get them to come out with their measuring device in a timely manner as there is only a single machine for the entire County.

All builder and developers are made aware of county noise ordinances, so if you think that they are being violated, you can call the County police and they will respond.

The same is true of continuously barking dogs. In both instances, we advise first talking to the property/dog owner before calling police.

For more information on the County's noise ordinances see the noise control section of the Montgomery County website.
