Denver Mandates Recycling, Composting for All Buildings by September 2026
Multi-family buildings, food businesses, permitted events and non-residential properties must provide recycling and composting services by September 1, 2026.
How we reported this
Denver's updated Universal Recycling and Composting Ordinance requires multi-family buildings, food businesses, permitted events and non-residential buildings to provide recycling and composting services by September 1, 2026. The rule applies directly to property owners and operators who must arrange collection services for residents and customers.
The Denver Metro-North Front Range area, which includes Denver, is classified as a severe ozone nonattainment area with federal attainment required no later than July 20, 2027. This classification stems from air quality standards under the Denver Department of Public Health & Environment oversight.
Green Buildings and Open Burning Rules
Denver's Green Buildings Ordinance mandates sustainable development strategies for new buildings, roof permits and additions of 25,000 square feet or larger. These measures target reductions in carbon impact and improvements in energy efficiency for qualifying projects. Open burning, including wood fire pits and solid-fuel devices, remains prohibited in Denver County on high-pollution days unless an approved permit or device is used.
The Denver Department of Public Health & Environment regulates nuisance odors through required Odor Control Plans. Facilities such as marijuana processing, sewage treatment and petroleum refining must meet complaint thresholds or dilution limits to operate in compliance.
Impact on Denver Residents
Residents in multi-family buildings will see property managers arrange new collection services for recyclables and compostables. Food businesses and event organizers must similarly adjust operations to meet the September 1, 2026 deadline. The changes connect to broader air quality requirements tied to the 2027 federal attainment date for the region.
Property owners planning additions or new construction at or above 25,000 square feet will follow the Green Buildings Ordinance requirements during permitting. Daily activities such as outdoor burning on high-pollution days face continued restrictions under existing county rules.
Next steps involve the Denver Department of Public Health & Environment and related city offices implementing the updated ordinance through permitting and compliance processes already outlined in city guidance documents.
