Broomfield, CO Animal Ordinances: Microchipping (2026)

Broomfield's general animal code does not mandate microchipping for ordinary pet ownership; routine identification instead relies on the rabies vaccination tag system in Chapter 6-16. Microchipping becomes mandatory only after an animal violates the unlawful-attacks chapter. Under Section 6-20-020(C), an owner of an animal seized for an unprovoked attack under Section 6-20-010 is entitled to a municipal court hearing to decide whether the animal will be destroyed. If the court determines destruction is not appropriate and orders the animal returned, subsection (C)(5) requires the court to order implantation of a unique identifying computer microchip by a licensed veterinarian at the owner's expense, and to order the owner to register that microchip information with animal control and the central microchip registry.

Section 6-20-030(A) applies the same microchip mandate even more broadly: for any unlawful attack defined in Section 6-20-010(A)(1) through (A)(3), whether or not the animal caused injury, the court must order microchip implantation and central-registry enrollment as part of sentencing. The microchip requirement also surfaces indirectly in Chapter 6-16: Section 6-16-250 lets a cat or dog owner who failed to register the animal for rabies get part of the minimum $150 fine waived by showing the animal already carries a registered identifying microchip, giving owners a financial incentive to microchip voluntarily even outside the attack context.
