What is an ISO rating?

ISO (Insurance Services Office Rating) classifies communities from 1 (the best) to 10 (the worst) based on how well they score on the ISO Fire Suppression Rating Schedule, which grades such features as water distribution, fire department equipment and manpower and fire alarm facilities. ISO field representatives use the schedule when surveying a community's fire protection capability. The score that is determined from applying the Fire Suppression Rating Schedule is translated into a public protection classification.

The current rating inside the city is a 2/2X/10.  To look up your ISO by your address, visit this link: https://www.sanmarcostx.gov/1142/ISO---Insurance-Services-Office-Rating
