Summary

Arvada requires every structure to be kept free of insect and rodent infestation. Once a structure is found infested, the property maintenance code demands prompt extermination using methods that won't harm human health, plus follow-up precautions to stop the pests from coming back.

"309.1. Infestation. All structures shall be kept free from insect and rodent infestation. All structures found to be infested by insects or rodents shall be promptly exterminated by approved processes that will not be injurious to human health. After extermination, proper precautions shall be taken to prevent reinfestation."

Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: City Council Policy Manual: Supplement 1 | Code of Ordinances: Supplement 67).

Full Breakdown

1, Infestation, to state that all structures must be kept free from insect and rodent infestation, that infested structures must be promptly exterminated by approved processes that will not injure human health, and that proper precautions must follow extermination to prevent reinfestation. The section doesn't name a specific pest list or set a numeric timeline for 'prompt' extermination, leaving that determination to the code official's inspection findings, but it applies to any structure regulated under Chapter 18, Article XI, residential and non-residential alike. The infestation rule sits between the city's sanitation standards for garbage and rubbish (§§ 18-514 through 18-520, requiring leakproof, covered containers and removal at least every 30 days) and the interior maintenance rules in Article IV of Chapter 18.

1 with a companion citation under the sanitation sections when the underlying cause is improperly stored waste. The section was carried into the current code by Ordinance No. for Chapter 18.

Violations & Fines

Infestation violations are enforced under Arvada's citywide general penalty, Code § 1-5: a fine up to $2,650.00, imprisonment up to 364 days, or both, for an adult convicted in Municipal Court, with each day an infestation goes untreated after notice counting as a separate offense.

Frequently Asked Questions

Who has to pay for rodent extermination in Arvada?
Section 18-521 places the duty on whoever is responsible for the structure under the property maintenance code's general responsibility rule, § 18-486, which names the owner as responsible for keeping the structure code-compliant, while occupants must keep the parts of the unit they control clean and sanitary.
What method of extermination does the code require?
The code requires an 'approved' process that will not be injurious to human health, without naming a specific pesticide or company. In practice the building inspection division looks for a licensed pest control response and follow-up precautions against reinfestation, both required by § 309.1.
Can I be cited for rodents even if I didn't cause the infestation?
Yes. Section 309.1 is a strict outcome standard: the code requires the structure be kept free of infestation and promptly treated once infested, regardless of the source, so a citation can still issue against the responsible owner or occupant even if the infestation originated elsewhere.
