Summary

Unlike unincorporated Los Angeles County, Lancaster has opted its dog owners out of the county's microchip mandate: Municipal Code Section 6.04.030 expressly declares the county ordinance's 'Microchipping of dogs required' provision inapplicable inside city limits, alongside the county's mandatory spay and neuter program for dogs.

Notwithstanding the provisions of Section 6.04.010 of this chapter, the following provisions of the county animal control ordinance are inapplicable in the City of Lancaster: Section 10.20.185 ("Microchipping of dogs required"); and Part 4 of Chapter 10.20 (commencing with Section 10.20.350) ("Mandatory spay and neuter program for dogs").

Full Breakdown

185. 350), as provisions of the county animal control ordinance that do not apply inside Lancaster. That means a Lancaster dog owner is not subject to a city or adopted-county mandate to microchip a pet, unlike an owner in the unincorporated county area next door. 08, which applies only to Pit Bulls and Rottweilers and carries its own unaltered-dog licensing and microchip-reporting requirements when a restricted-breed puppy changes hands (Sec. 060(D)). 030 overrides the county's general microchip mandate for city residents.

Violations & Fines

Because Section 6.04.030 removes the county's microchip and spay/neuter mandate from Lancaster's adopted code, there is no city penalty for failing to microchip a dog. Owners should note this exemption does not touch the separate, narrower mandatory spay and neuter program the city does enforce under Chapter 6.08 for Pit Bulls and Rottweilers, which carries its own fines and impoundment consequences.

Frequently Asked Questions

Is my dog required to have a microchip in Lancaster, CA?
No. Section 6.04.030 of the Lancaster Municipal Code specifically declares Los Angeles County's microchipping requirement, Section 10.20.185 of the county animal control ordinance, inapplicable inside the city, even though Lancaster otherwise adopts the county's Title 10 animal code by reference under Section 6.04.010.
Why doesn't Lancaster follow the county's dog microchip law?
Lancaster adopts the county animal control ordinance by reference but reserves the right to amend or exclude parts of it under Section 6.04.010(B). Section 6.04.030 exercises that authority to exclude both the county's microchip requirement and its general mandatory spay and neuter program, replacing the latter with the city's own narrower breed-specific program in Chapter 6.08.
Does Lancaster require spay or neuter for all dogs?
No, not for all dogs. Section 6.04.030 excludes the county's general mandatory spay and neuter program from applying in Lancaster. The city instead enforces its own mandatory spay and neuter requirement in Chapter 6.08, but only for dogs classified as Pit Bulls or Rottweilers under Section 6.08.020.
