How do we build bear-resistant trash enclosures for our HOA in Colorado?

By OurHOA · General information · Revised October 29, 2026

Colorado HOA boards: what the 2026 bear-luring law and local codes require, how to build or buy a bear-resistant trash enclosure, and owner rules.

Part of the HOA board handbook: vendors, projects and upkeep.

The short answer

If bears reach your community's trash, the board needs to fix the storage, not just post reminders. In Colorado that means one of three setups: IGBC-certified bear-resistant dumpsters or carts, a fully closed enclosure (four walls, a roof or lid, and a door that latches), or a rule that keeps trash inside garages until the morning of pickup. Most associations end up with a mix: certified dumpsters or a built enclosure at the common collection point, and a cart rule for homes with curbside service. The legal pressure went up in 2026. House Bill 26-1342 rewrote the state bear-luring statute, C.R.S. 33-6-131, effective August 12, 2026. A person who knowingly leaves food or edible waste in the open where there is a reasonable probability of luring a wild bear now commits a misdemeanor, with no required warning first. Your city or county may add its own container rules on top. Rules vary by town, county and by your governing documents, and this guide is education, not legal advice.

What state law and local codes require

The state law. Before HB 26-1342, the statute reached only people who left food out with the intent of luring a bear, and a first violation got a warning. The new version uses "knowingly" and "reasonable probability," and the warning step is gone; Colorado Parks and Wildlife officers and other peace officers can warn or cite. Fines run up to $200 for a first offense, $1,000 for a second and $5,000 for a third or later one. Acts related to agriculture are exempt. The legislature's findings explain why. In 2024 CPW received more than 5,000 bear sighting and conflict reports, over half of them linked to trash and food waste, and 98 bears were euthanized. CPW said unsecured trash was tied to more than 57% of property-damage reports in 2025. Local codes. Many mountain and Front Range towns have their own rules, so pull your municipal or county code before you buy anything. Two examples: Boulder requires bear-resistant containers citywide for trash and compost put out the night before pickup. In the zone west of Broadway and south of Sumac Avenue, all trash and compost carts, dumpsters and enclosures must be bear-resistant, or the trash must stay inside a building until the hauler empties it. The city fines $100, $250 and $500 for the first three offenses and says violators do not get warnings. Larimer County's Wildlife Protection Ordinance, enforced since September 1, 2017, covers only the Estes Valley Planning Area. Residential refuse may sit outside only on pickup day between 6 a.m. and 7 p.m. unless it is in a wildlife-resistant container or enclosure. Businesses and vacation rentals must use one at all times, which matters if your community has a clubhouse with food service or a lot of short-term rentals.

Pick the setup that fits your community

Start by listing every collection point: shared dumpsters, cart rows at mailbox clusters, curbside carts, compost and recycling. Shared dumpsters. Ask your hauler first. Larimer County notes that wildlife-resistant dumpsters are readily available and often cost little or nothing extra to switch to, and the IGBC list includes steel bear-lid dumpsters in 2- to 8-yard sizes. If you retrofit a lid instead, confirm the hauler's trucks can empty it and that drivers will close the latch after pickup. Put that duty in the hauling contract. Built enclosures. A walled corral around a dumpster or cart row works if it is fully closed. A three-sided screen fence with no roof is decoration, not bear protection. Owner carts. For curbside homes, the options are certified bear-resistant carts (from the hauler or bought by owners) or a rule that carts stay in garages until pickup morning. A cart rule costs the association nothing but depends on enforcement. Check certification yourself. The Interagency Grizzly Bear Committee keeps the list of certified bear-resistant products, and its October 2026 list includes dumpsters, trash enclosures and cart enclosures. IGBC says the reliable check is to match the certification number on the product to the list, because not every maker prints the logo and some products sold as "bear-resistant" were never tested. Certification is not a promise that no bear ever gets in. IGBC also does not decide what satisfies a given ordinance; your town or county does.

Building an enclosure that holds

Boulder's guidance is the most specific public standard we found, and it makes a good spec sheet even outside Boulder. The city defines a bear-resistant enclosure as a structure of metal, wood, stone, brick, concrete or equally sturdy material with five sides (four walls and a roof), a secure door or cover, and a latching device. Its design guidelines add: 1. Walls run all the way to the ground. 2. The gap under the door is no more than 2 inches. 3. Vents are covered with heavy steel mesh. 4. Other gaps are ideally 3/8 inch or less. Boulder notes that a wood enclosure built to those criteria counts as an enclosure under its ordinance but is not IGBC certified, and only containers, not enclosures, need IGBC certification there. Check whether your own town draws the same line. Practical points that save trouble later. Use a latch a bear cannot hook with a claw, such as a lever latch that needs a thumb or a slide bolt with a carabiner, and mount it at adult height. Hang the door to swing shut on its own; the most common failure is a door left open by a resident with full hands. Make the opening wide enough for the hauler to roll a dumpster out. Pour a concrete pad so the structure cannot be dug under and can be hosed down. Get the enclosure drawings approved by your town before you build. Some codes treat it as an accessory structure needing a permit and setback review, and your own architectural rules may control color and materials.

Rules and notices for owners

Hardware fails if residents leave the latch open. Adopt a written rule under the authority your declaration gives the board, follow your notice-and-comment process, and enforce it through your existing fine policy. Colorado associations must have a covenant enforcement policy under C.R.S. 38-33.3-209.5, so tie the rule to it. Florida associations have a ready model: the Florida Fish and Wildlife Conservation Commission publishes a sample HOA bylaw requiring garbage to stay in a wildlife-resistant container or a sturdy shed or garage except on pickup day, along with rules for pet food, grills and bird feeders. Colorado boards can borrow its structure. Sample rule: "Household trash and compost must be kept in a garage, in a closed shed, or in a bear-resistant container certified by the Interagency Grizzly Bear Committee. Carts may be placed at the curb no earlier than 6 a.m. on collection day and must be returned by 7 p.m. The doors of the common trash enclosure must be latched after every use. Trash may not be left outside the enclosure or beside a dumpster." Sample owner notice: "Bears have been reported in the community's trash this month. Under state law, leaving trash where it is likely to attract a bear can now bring a fine of up to $200 for a first offense. Please latch the enclosure door every time, break down boxes, and never leave bags on the ground. If the latch is broken or a bin is full, email the manager right away." Do the same audit on common amenities: the pool deck and clubhouse trash cans, grills at the pavilion, and dog waste stations.

A sample timeline

Winter (December to February). Pull the town and county code, call the hauler for bear-resistant dumpster pricing, and get two bids for enclosures. Put the cost in the budget or the reserve plan. March. Board meeting: adopt the trash rule and approve the project. Sample motion: "I move that the board approve [contractor] to build bear-resistant enclosures at the two collection points described in the attached drawings, at a cost not to exceed $[amount], subject to town permit approval, and adopt the attached trash storage rule effective [date]." April. Build or retrofit before the busy season; your local CPW office can tell you when bear activity usually picks up in your area. Mail the rule and the owner notice. May through November. Inspect latches and doors monthly. Ask the hauler to report open lids. Log every bear sighting or break-in with the date and location and report conflicts to CPW. Clean enclosures and bins on a schedule; CPW recommends bleach or ammonia because empty containers still smell like food. December. Review the log. If bears kept getting in at one site, fix the hardware there before spring.

Mistakes boards make

Buying "bear-resistant" products that are not on the IGBC list. Building a screen fence with no roof. Choosing a latch that residents find annoying, so they tape it open. Not telling the hauler, whose drivers then leave lids open. Fining owners before the association's own enclosure works. Forgetting recycling and compost, which still smell. And waiting until a bear is euthanized to act; the legislature's own findings count 98 bears euthanized in 2024 after incidents with people.
