2. May not be rented, sublet, or sold separately from sale of the entire property, including the principal dwelling unit.
3. Shall have the same address and share the mailbox with the principal dwelling. Multiple mailboxes are prohibited.
4. Shall be specifically permitted for such purpose.

Full Breakdown
Under § 11.04.032(A)(1), Cedar Park ties ADU ownership directly to the main house: the accessory unit 'shall be owned by the same person(s) who own(s) the principal dwelling unit.' Combined with the bar on separate sale in § 11.04.032(A)(2), an ADU can't be conveyed, financed, or titled independently of the primary residence, under the zoning code the two stay permanently linked as one property for as long as the ADU exists.
Violations & Fines
Titling, financing, or otherwise recording ownership of an ADU separately from the principal dwelling violates § 11.04.032(A)(1) and can void the ADU permit and draw Code Compliance enforcement.
