Construction activities are subject to the Dust Control Ordinance requirements contained in San Francisco Health Code Article 22B and San Francisco Building Code Section 106.A.3.2.6.

Requirements of the Dust Control Ordinance include, but are not limited to, watering to prevent dust from becoming airborne, sweep or vacuum sidewalks, and cover inactive stockpiles of dirt. These measures ensure that serpentinite does not become airborne during construction.

Under the California Environmental Quality Act (CEQA), certain types of work on a property may require additional environmental review. CityStructure Reports will show you if any of these restrictions apply to your property.
