005's stated purpose, charge the cost as a personal obligation and/or a lien on the property. 050 provides that a person's failure to receive mailed notice does not invalidate the proceedings, so an out-of-date mailing address on file for a vacant parcel does not stop the process.
Violations & Fines
Ignoring a Section 9.26.040 notice lets the city abate the nuisance itself and bill the owner; unpaid costs become a lien on the parcel under the chapter's abatement authority. Because notice is deemed adequate once mailed to the address on the latest county assessment roll, owners of unimproved land who do not keep a current mailing address on file risk a lien attaching without ever seeing the notice.
