SDCI Closures, Service Updates, and Inspection Requirements

SDCI customer service areas remain closed until further notice and continue offering services online. King County has approval from the State Department of Health to allow all private construction activities that are low-risk and adhere to strict COVID 19 Job site Requirements. The City of Seattle has issued requirements for construction projects seeking inspections. The City WILL NOT INSPECT any site that does not follow these requirements.


Summary: Natural ventilation is the use of a building’s form, organization, and openings in conjunction with naturally occurring phenomenon, such as the wind or warm air buoyancy, to supply air to its occupants and to remove heat from both the occupants and the building. Forms of natural ventilation activated by the forces of gravity are called stack entilation. Wind-driven systems are referred to as cross ventilation.
