Per Mountain View City Code Section 8.10, no construction activity shall commence prior to 7 am nor continue later than 6 pm Monday through Friday. No work is permitted on Saturday unless prior written approval is granted by the Chief Building Official. No construction activity is allowed on Sunday or recognized holidays.

"Construction activity" means any physical activity on the construction site or in the staging area, including the delivery of materials. 

The Chief Building Official may approve modified construction hours and may specifically designate and/or limit the activities permitted during the modified hours.

Modified Construction Hours

At any time before commencement of or during construction activity, the Chief Building Official may modify the permitted hours of construction upon 24 hours written notice to the contractor/applicant/owner. The Chief Building Official can reduce or increase the allowable hours of construction activity. 

Construction Sign Required

If the hours of construction activity are modified OR a planning permit requires it, then the general contractor/applicant/owner must install a sign at a prominent location, such as the entrance/exits, on the construction site to advise subcontractors and material suppliers of the construction working hours. The contractor/applicant/owner must produce a copy of the written order or permit from the Chief Building Official regarding construction hours upon the request of any member of the public, Police or City staff.
