7.24.010 - Findings, purpose, and intent.¶
A. Findings. The City Council finds and declares as follows:
Section VII of Article XI of the California Constitution provides that a city may make and enforce within its limits all local, police, sanitary, and other ordinances and regulations not in conflict with general laws.
California Government Code Section 38771 provides that legislative bodies of cities may declare what constitutes a nuisance.
California Government Code Section 38772 et seq. further provides that legislative bodies of cities may also provide for the summary abatement of any nuisance at the expense of the persons creating, causing, committing, or maintaining it and by ordinance may make the expense of abatement of nuisances a lien against the property on which the nuisance is maintained and a personal obligation against the property owner.
Nuisance conditions are offensive or annoying to the senses, detrimental to property values and community appearance, an obstruction or interference with the comfortable enjoyment of adjacent properties or premises (both public and private) and/or are hazardous or injurious to the health, safety, or welfare of the general public.
B. Purpose and Intent. The purpose and intent of this chapter are as follows:
To define as public nuisances and violations those conditions and uses of land that are offensive or annoying to the senses, detrimental to property values and community appearance, an obstruction or interference with the comfortable enjoyment of adjacent properties or premises (both public and private), and/or are hazardous or injurious to the health, safety, or welfare of the general public.
To develop regulations that will promote the sound maintenance of property and enhance of conditions of appearance, habitability, occupancy, use, and safety of all structures and premises in the City.
To establish administrative procedures for the City's use, upon its election, to, correct or abate violations of this chapter on real property throughout the City.
Nothing in this chapter shall be deemed to prevent the City at any time from commencing an administrative, civil, or criminal proceeding to abate a public nuisance or from pursuing other means available to it under the provisions of any applicable law to correct substandard, hazardous, or nuisance conditions or deficiencies in real property in addition to or as an alternative to the proceedings set forth herein.
This chapter is not the exclusive regulation of property maintenance, nor is it intended to affect or otherwise alter nuisance abatement procedures established or that may be established in other chapters of this Code. It shall be supplemental and in addition to other regulatory codes, statutes, and ordinances heretofore or hereinafter enacted by the City, State of California, or other legal entity or agency having jurisdiction.
This chapter is not intended to be applied, construed, or given effect in a manner that imposes upon the City, or upon any officer or employee thereof, any duty towards persons or property within the City or outside of the City that creates a basis for civil liability for damages, except as otherwise imposed by law.
(Ord. No. 09-911, § 3, 1-4-10)

A. Any one or more of the following conditions are found to exist thereon:

Buildings or other structures, or portions thereof, that are partially constructed or destroyed or allowed to remain in a state of partial construction or destruction for an unreasonable period of time. As used herein, an "unreasonable" period shall mean any portion of time exceeding the period given to a responsible person by the City for the complete abatement of this nuisance condition with all required City approvals, permits, and inspections. Factors that may be used by the City to establish a reasonable period for the complete abatement of this nuisance include, but are not limited to, the following:

d. The scope and type of work that is needed to abate this nuisance.
e. The promptness with which a responsible person has applied for and obtained all required City approvals and permits in order to lawfully commence the nuisance abatement actions.
f. Whether or not a responsible person has complied with other required technical code requirements, including requesting and passing required inspections in a timely manner, while completing nuisance abatement actions.
