The most frequently cited code violations in unincorporated LA County include construction without permits, illegal dwelling units (garage conversions), overgrown vegetation, unpermitted signage, and property maintenance failures such as accumulated debris and dilapidated structures.
LA County Department of Public Works Building and Safety regularly investigates violations of Title 26 (Building Code) and Title 22 (Planning and Zoning). Common violations include: construction or remodeling done without proper permits, illegal conversion of garages into living spaces, unpermitted accessory dwelling units, outdoor storage and debris accumulation, overgrown vegetation creating fire hazards, fences or walls exceeding height limits, commercial activity in residential zones (illegal home businesses), junk vehicles on residential property, and missing or non-functional pool safety barriers. Given the county's fire risk, weed abatement and brush clearance violations are especially common in hillside and wildland-urban interface areas. The county works with the LA County Fire Department on fire hazard abatement.
Penalties vary by violation type. Unpermitted construction may result in double permit fees plus correction costs. Fire hazard vegetation violations can result in county-performed abatement with costs billed to the property owner, often $500-$2,000+.
