Half the city rents and most are uninsured
A renters policy is among the cheapest sold and covers belongings, liability and somewhere to stay when a unit becomes uninhabitable. The landlord's policy does none of those things, and in a city where half of households rent that gap is the largest single exposure on this page.
An Arizona policy stops at the border
Personal auto policies written in the United States generally do not provide liability cover in Mexico, and Mexican law requires insurance issued by an admitted Mexican carrier. Driving south on a US policy alone is the kind of gap that becomes a detention rather than a claim.
Vehicles and premises used for trade
Produce, warehousing and freight are the local economy, and a personal auto or homeowners policy excludes business use. Where a vehicle or a building is working, it needs a commercial form, and the distinction is sharper than most people assume.
