Summary
LA County declares any property maintained in a defective, unsightly, or deteriorated condition that diminishes neighboring property values or constitutes a public nuisance as 'substandard property,' triggering abatement orders and potential county action.
9905.13
Property, including, but not limited to, building exteriors which are maintained in such condition as to become so defective, unsightly, or in such condition of deterioration or disrepair that the same causes appreciable diminution of the property values of surrounding property or is materially detrimental to proximal properties and improvements. This includes, but is not limited to, the keeping or disposing of or the scattering over the property or premises of any of the following:
1.Lumber, junk, trash or debris;2.Abandoned, discarded, or unused objects of equipment such as automobiles, furniture, stoves, refrigerators, freezers, cans, or containers,3.Stagnant water, or excavations; or4.Any device, decoration, design, fence, structure, clothesline, or vegetation which is unsightly by reason of its condition or its inappropriate location. (Ord. 2010-0053 § 89, 2010.)
Full Breakdown
Chapter 99 of Title 26 lists substandard property conditions including overgrown vegetation, dead trees and debris, abandoned vehicles, broken furniture left outdoors for unreasonable periods, and building exteriors in disrepair that diminish surrounding property values (§ 9905.4–9905.14). Once the Building Official finds substandard conditions, a written Notice of Substandard Property is issued requiring abatement within 30 days (or another stipulated period). If the owner doesn't act, the county may perform the abatement and recover costs as a special assessment against the property on the tax bill.
Violations & Fines
Owners who fail to comply with a Notice of Substandard Property (and neither they nor others request a hearing) are guilty of a misdemeanor under § 9932. The county can perform abatement work and the costs become a special assessment on the property's tax bill under Government Code § 25845.
