AZ SB1511

Requires that petition signatures for district formation and boundary changes count only one signature per property owner, even if multiple people own the same property.

Adds requirement that petition signatures are invalid if taxes and assessments on the property are not current at the time of petition review for district formation.

Clarifies that leaseholders cannot sign formation or boundary change petitions for community park maintenance districts; only the real property owner's signature is valid.

Modifies the petition signature requirement to specify "number of persons who own property" rather than "property owners" to prevent multiple owners of the same parcel from each signing separately.

Applies to fire districts, community park maintenance districts, sanitary districts, and hospital districts in Arizona.
