Insurance companies may consider:

  • Building replacement cost
  • Square footage
  • Construction type
  • Building age
  • Roof age
  • Electrical system
  • Plumbing
  • HVAC
  • Sprinkler system
  • Fire alarms
  • Central station alarms
  • Distance to fire hydrant
  • Distance to fire department
  • Occupancy
  • Tenant type
  • Vacancy
  • Claims history
  • Geographic location
  • Crime exposure
  • Flood exposure
  • Severe-weather exposure
  • Number of units
  • Rental income

This is why two buildings with the same market value can have very different insurance premiums.
