CA Sts & High Code Section 5898.15

(a)

A public agency shall not permit a property owner to participate in any program established pursuant to this chapter if the owner’s participation would result in the total amount of any annual property taxes and assessments exceeding 5 percent of the property’s market value, as determined at the time of approval of the owner’s contractual assessment.

(b)

Nothing in this chapter shall be construed to void or otherwise release a property owner from the contractual obligations incurred by a contractual assessment on a property, particularly in the event that the total amount of annual property taxes and assessments exceeds 5 percent of a property’s market value after the property owner has entered into a contractual assessment pursuant to this chapter.
