A second home in Arizona

Arizona taxes a home the owner lives in as their primary residence as class three property. A home a qualifying relative lives in as their primary residence can be class three too. azleg.govOct 21
To decide if a home is your primary residence, officials look at how long you live there each year, your voting precinct, your driver license address and where your vehicles are registered. azleg.govOct 21
If the assessor thinks a class three home isn't your primary residence, you'll get a notice asking if it's a secondary residence or a rental. Don't answer within 15 days of the final notice and it's moved to class four, with a civil penalty equal to the prior year's state aid. azleg.govOct 21
If you own residential rental property, you must keep your details on file with the county assessor and update them within ten days of a change. Owners who live outside Arizona must name a statutory agent who lives in the state. azleg.govOct 21

A second home in California

Rentals and vacation homes don't qualify for the homeowners' exemption. boe.ca.govOct 21
Under Proposition 13, property is reassessed to market value only when it changes owner or has new construction. Otherwise yearly increases in real property's base year value are generally limited to 2 percent. boe.ca.govOct 21
