Violations & Fines
Violating Lancaster's pool-fence chapter is a misdemeanor under Section 8.04.320; a sheriff's deputy may arrest the owner or release them on a written promise to appear per Los Angeles County Ordinance No. 6723. Fences that fail the post spacing, embedment, or thickness specifications in Sections 8.04.240 through 8.04.260, or gates lacking self-closing, self-latching hardware under Section 8.04.290, are non-compliant regardless of intent.
