What is 504?
The 504 Request Form, printed as the 504 Mobile Home Request Form, is the Maricopa County Assessor document that notifies the Assessor that a mobile or manufactured home is being moved from one location to another. The form states that it must be obtained before the move.
The form collects the information the Assessor needs to identify the unit and follow it: contact details, the mobile home's Vehicle Identification Number, Tax Roll Account # and year, make and size, whether the home is affixed to a parcel, the mover's name and phone, and the addresses the home is moving from and to, including the county it is moving to. It also asks whether the tax clearance should be emailed or faxed to you.
The form opens with a legal warning. Under A.R.S. § 42-19107 and A.R.S. § 42-19155, it is unlawful for any person to knowingly move or sell a mobile home if applicable property taxes have not been paid. A person who violates this provision is guilty of a Class 1 misdemeanor and subject to a fine.
The form says plainly that the request is not a property tax clearance statement. The Assessor's Mobile Homes forms list also includes an online version (Online 504 Request Form), a Spanish version (Formulario de Solicitud para Casa Móvil 504) and the Affidavit of Affixture (DOR 82528), which are separate documents.
Who needs to file 504?
Anyone who is going to move a mobile or manufactured home in Maricopa County files the 504 Request Form. The form states that, prior to moving a mobile/manufactured home, it is required to obtain a 504 Mobile Home Request Form.
The form has a contact person (name, phone, email and fax) and a separate section for the mover, so the person arranging the move and the company or person doing the move can be different. It also asks for the county the home is moving to, so it is used whether the destination is inside or outside Maricopa County.
Do not treat the request as proof that taxes are paid. The form itself says the request is not a property tax clearance statement, and its legal notice says it is unlawful to knowingly move or sell a mobile home if applicable property taxes have not been paid. The form does not describe who may sign or file for another person and has no signature line.
When to file 504
Submit the 504 Request Form before the mobile or manufactured home is moved. The form says that obtaining it is required prior to moving, and that it notifies the Assessor that the unit is going from one location to another.
The form has a Date line at the top, which you complete when you prepare the request. It prints no other deadline, validity period or processing time. Because the legal notice on the form makes it unlawful to knowingly move or sell a mobile home when applicable property taxes are unpaid, send the request early enough to receive the tax clearance by the delivery method you select on the form.

Common mistakes to avoid
- Moving the mobile home before obtaining the 504 Request Form; the form says it is required prior to moving.
- Treating the 504 request as a property tax clearance statement; the form states it is not one.
- Moving or selling a mobile home knowingly while applicable property taxes are unpaid, which the form's legal notice calls unlawful and a Class 1 misdemeanor.
- Not selecting whether the tax clearance will be emailed or faxed, or giving no matching email address or fax number.
- Leaving out the Vehicle Identification Number or the Tax Roll Account # and year, which identify the unit.
- Skipping the Affixed to Parcel Yes or No answer.
- Omitting the Lot/Space, city, state or ZIP for the moving-from or moving-to location, or the county moving to.
- Sending the completed form somewhere other than the email address or fax number the form gives.
