Seismic

The city's seismic ordinance classifies the various building code occupancies into five "relative hazard" levels. Locating a doggie day care in a building that shows in our permit records as a legal warehouse or manufacturing building would require that the entire building be seismically upgraded if the area being converted to a B occupancy would be more than 1/3 of the building's total floor area.

Changing office or retail space to doggie day care would generally not require a seismic upgrade, since these uses are classified at a similar hazard level. It is important to research any potential location to find out its current legal use.

For more information on seismic triggers and your project, visit the Development Services Center or call a Life Safety Reviewer at (503) 823-1456.
