AZ HB2543

Requires building permit applicants for new single-family residential construction to disclose all ownership interests in the property and include an approved public report if the owner holds six or more properties within the parent parcel or intends to create a subdivision.

Land division and minor lot split applications must include attestation language confirming the applicant understands public report requirements under Arizona subdivision laws and acknowledges penalties for non-compliance.

Applicants must disclose ownership interests in the property subject to land division applications and any ownership interests in the parent parcel if the property was divided within the last ten years.

Counties may deny building permits if required public reports are not obtained, and the State Real Estate Department may impose civil penalties, record violation notices, and issue cease and desist orders against non-compliant subdividers.

Redefines "parent parcel" as a parcel less than 160 acres or any subsequent land division of ten or more acres, and clarifies that lots created from the same parent parcel do not qualify as separated by a "barrier" unless deeded to a municipality or homeowner's association.
