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.
