It shall be unlawful for any person, between the hours of 8:00 p.m. of any day and 7:00 a.m. of the following day to erect, construct, demolish, excavate for, alter or repair any building or structure if the noise level created thereby is in excess of the ambient noise level by 5 dBA at the nearest property plane, unless a special permit therefor has been applied for and granted by the Director of Public Works or the Director of Building Inspection. In granting such special permit the Director of Public Works or the Director of Building Inspection shall consider: if construction noise in the vicinity of the proposed work site would be less objectionable at night than during daytime because of different population levels or different neighboring activities if obstruction and interference with traffic, particularly on streets of major importance, would be less objectionable at night than during daytime; if the kind of work to be performed emits noises at such a low level as to not cause significant disturbance in the vicinity of the work site, if the neighborhood of the proposed work site is primarily residential in character wherein sleep could be disturbed: if great economic hardship would occur if the work were spread over a longer timers if the work will abate or prevent hazard to life or property; and if the proposed night work is in the general public interest. The Director of Public Works or the Director of Building Inspection shall prescribe such conditions, working times, types of construction equipment to be used, and permissible noise emissions, as required in the public interest.
The provisions of this Section shall not be applicable to emergency work.

(2) No person shall produce or allow to be produced by any machine, or device, music or entertainment or any combination of same, on multi-unit residential property over which the person has ownership or control, a noise level more than five dBA above the local ambient three feet from any wall, floor, or ceiling inside any dwelling unit on the same property, when the windows and doors of the dwelling unit are closed, except within the dwelling unit in which the noise source or sources may be located.
(b) Commercial And Industrial Property Noise Limits. No person shall produce or allow to be produced by any machine, or device, music or entertainment or any combination of same, on commercial or industrial property over which the person has ownership or control, a noise level more than eight dBA above the local ambient at any point outside of the property plane.

(d) Fixed Residential Interior Noise Limits. In order to prevent sleep disturbance, protect public health and prevent the acoustical environment from progressive deterioration due to the increasing use and influence of mechanical equipment, no fixed noise source may cause the noise level measured inside any sleeping or living room in any dwelling unit located on residential property to exceed 45 dBA between the hours of 10:00 p.m. to 7:00 a.m. or 55 dBA between the hours of 7:00 a.m. to 10:00p.m. with windows open except where building ventilation is achieved through mechanical systems that allow windows to remain closed.
(e) Noise Caused By Activities Subject To Permits From the City and County of San Francisco.

(a) For purposes of this Section, "Unenclosed Tour Bus" shall mean a privately-owned passenger vehicle for hire with a capacity of nine or more passengers, including the driver, that:
(1) is used primarily for the conveyance of passengers over the public streets, for the purpose of visiting or viewing places of interest; and
(2) lacks either a permanently attached solid roof covering all seating areas of the vehicle or permanently attached side panels, which with any doors or windows closed, fully enclose the sides of the vehicle.
(b) Effective October 1, 2012, it shall be a violation of this Section for any Person to operate an Unenclosed Tour Bus using electronically amplified sound to communicate with passengers without having received authorization from the Director of the Department of Public Health or his or her designee ("Director of Public Health") that the sound system is in compliance with the requirements of this Section.
(c) The Director of Public Health may approve the electronically amplified sound system on an Unenclosed Tour Bus and issue a Certificate of Authorization to Operate Electronically Amplified Sound on Unenclosed Tour Buses ("Certificate") where the Director of Public Health determines that either:
(1) At maximum volume and without modification, the sound system is not audible at a distance of 50 or more feet outside the vehicle with the vehicle windows open and any operable or removable roof or side panels opened or removed; or
(2) The sound system includes volume limiting technology, which in its default mode prevents the sound system from being heard at a distance of 50 or more feet outside the vehicle. Such a system may include an override mode for use in emergencies.
(d) Following a hearing, the Director of Public Health may suspend or revoke a Certificate for any violation of this Section. The Director of Public Health may base such action on 1) the Director of Public Health's determination that the Certificate holder has violated this Section; or 2) a citation from the San Francisco Police Department for any violation of this Section or California Vehicle Code Section 27007, or any successor provisions. A Certificate holder may appeal the suspension or revocation of a Certificate to the Board of Appeals.
(e) The Owner or Operator of the Unenclosed Tour Bus shall post the Certificate in a clearly visible location on the exterior of the vehicle.
(f) The Director of Public Health shall review the compliance history of each approved Unenclosed Tour Bus and reinspect the Unenclosed Tour Bus annually, and upon any change in ownership, and if found in compliance with this Section and any implementing regulations, the Director of Public Health may reissue the Certificate.
(g) The Director of Public Health shall report to the Board of Supervisors one year from the effective date of this ordinance and every two years thereafter:
(1) the number of Certificates issued to Unenclosed Tour Buses;

Not later than April 1, the Director of Public Health shall report to the Controller the revenues generated by the fees for the prior fiscal year and the prior fiscal year's costs of operation, as well as any other information that the Controller determines appropriate to the performance of the duties set forth in this Section.
Not later than May 15, the Controller shall determine whether the current fees have produced or are projected to produce revenues sufficient to support the costs of providing the services for which the fees are assessed and that the fees will not produce revenue that is significantly more than the costs of providing the services for which the fees are assessed.
The Controller shall, if necessary, adjust the fees upward or downward for the upcoming fiscal year as appropriate to ensure that the program recovers the costs of operation without producing revenue which is significantly more than such costs. The adjusted rates shall become operative on July 1.
(j) The requirements of this Section shall not apply to an Unenclosed Tour Bus equipped with and using electronically amplified sound to communicate with passengers where all non-emergency communications through the system are audible to passengers only through technology designed to make such communications audible only to the individual listener, such as individual headsets or headphones.
