Summary

Adams County Ordinance No. 3 makes it unlawful to store rubbish, junk, weeds, brush or inoperable vehicles outside on any unincorporated property. Public Works can order removal within 14 days, seek a court warrant to seize and dispose of the blight, and place a lien with escalating costs on repeat offenders.

City-specific rules exist: Thornton, and Westminster have their own property blight rules that differ from Adams County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

It shall be unlawful for any person to maintain or permit to be maintained any of the following causes of blight or blighting factors upon any property in unincorporated Adams County owned, leased, rented or occupied by such person: (1) The outside storage or accumulation of rubbish, junk, trash, garbage, weeds, brush or refuse of any kind. Domestic refuse stored in a closed container in such a manner as not to create a nuisance for a period not to exceed thirty (30) days shall be exempt from this section. The term "junk" shall include, but shall not be limited to, parts of machinery or motor vehicles, inoperable vehicles whether on private property or County public right-of-way, unused stoves or appliances stored in the open, boxes, grass clippings, remnants of wood, metal, plastic, dilapidated signs, fences or retaining walls, or any other material or other cast-off material of any kind, whether or not the same could be put to any reasonable use.

Full Breakdown

Ordinance No. 3, effective March 29, 2010, declares it unlawful for anyone to maintain outside storage or accumulation of rubbish, junk, trash, garbage, weeds, brush or refuse on property they own, lease, rent or occupy in unincorporated Adams County. Junk is defined broadly to include machinery or motor vehicle parts, inoperable vehicles on private property or county right-of-way, appliances stored outside, dilapidated signs, fences or retaining walls, and other cast-off material regardless of reuse value. Domestic refuse kept in a closed container for no more than 30 days is exempt, and the storage rule does not apply where it is incidental and necessary to a lawfully operating business consistent with county zoning.

The Director of Public Works, including zoning inspectors and environmental compliance agents, inspects unincorporated property and enforces the ordinance. When blight is found, the county mails or personally delivers notice to the owner and occupant giving 14 days to remove it and the right to request an Adams County Court hearing within that same 14 days. If the owner does neither, Public Works may apply for an administrative entry and seizure warrant from the county court, execute it within 10 days, and remove and dispose of the material; if a hearing is requested and the court still issues a warrant, the same 10-day execution process applies.

The county recovers its removal cost, plus a 10 percent inspection surcharge for weeds and brush or 5 percent for rubbish, junk, trash and garbage, as a special assessment lien against the property with priority over all but general taxes and prior special assessments. Unpaid assessments are certified to the County Treasurer after 60 days and collected like property taxes with an added 10 percent collection penalty.

Violations & Fines

Failing to remove blight after notice violates the ordinance and does not preclude separate zoning or building-code prosecution under C.R.S. §§ 30-28-124 and 30-28-209, including fines or imprisonment. Repeat offenders face a graduated cost multiplier: the county's removal and inspection costs are doubled and assessed as a lien for a second offense, and tripled for a third or later offense.

Frequently Asked Questions

What counts as blight in unincorporated Adams County?
Ordinance No. 3 defines it as outside storage or accumulation of rubbish, junk, trash, garbage, weeds or brush, including inoperable vehicles, unused appliances, and dilapidated signs, fences or retaining walls left on a property, whether or not the material could still be put to reasonable use.
How much notice do I get before the county removes blight from my property?
The Director of Public Works must mail or personally deliver notice describing the blight, demand its removal within 14 days, and explain your right to request an Adams County Court hearing within that same 14-day period before any warrant is sought.
Can the county put a lien on my property for cleanup costs?
Yes. Under Section IV of Ordinance No. 3, the full cost of removal, plus a 10 percent surcharge for weeds and brush or 5 percent for rubbish, becomes a special assessment lien with priority over every claim except general taxes and earlier special assessments.
What if I ignore the notice more than once?
Repeat violations cost more. The county doubles its removal and inspection cost for a second offense and triples it for a third or later offense, and each amount is still assessed as a lien against the property under Section IV(D) of the ordinance.
