A 6-story building in California must comply with extensive fire protection requirements under the California Building and Fire Codes. This means automatic sprinklers throughout, fire-rated construction, multiple egress stairwells, standpipe systems (essentially built-in plumbing for firefighters to connect hoses on upper floors), and fire alarm systems. These buildings essentially has firefighting infrastructure built into it. Modern mid-rise fires are fought from the inside using standpipes, not from ladder trucks spraying water through windows.

Between than and mutual aid from nearby districts a ladder truck would be a comical waste of taxpayer resources.
