Castaic FAQ

How much can I save with a Mills Act contract?

Most participants see property tax bills drop 60 to 70 percent because the Assessor switches to a capitalized income valuation method. Savings vary based on rental income, property condition, and Proposition 13 base.

What if I sell my Mills Act property?

The contract runs with the land. The new owner inherits both the tax reduction and the maintenance obligations. Cancellation by either party triggers a 12.5 percent of full value penalty under state law.

Los Angeles FAQ

Does the Mills Act apply to commercial buildings?

Yes. Owner-occupied homes, rental housing, and commercial HCMs all qualify. Larger commercial properties have a maximum assessed-value cap under Los Angeles program rules to focus benefits on smaller owners.

What happens if I sell a Mills Act property?

The contract runs with the land. New owners inherit both the tax savings and the maintenance obligations under Government Code Section 50281, and the rolling 10-year term continues unchanged.
