September 1, 2026 is the compliance deadline for Denver’s “Waste No More” ordinance — and if you’re pulling permits for construction, demolition, or a larger renovation in Denver after that date, this affects you whether or not your project has anything to do with LEED.
What’s Actually Changing
Denver voters approved “Waste No More” back in 2022. On September 15, 2025, City Council passed the updated rules for construction and demolition specifically, with a compliance deadline of September 1, 2026. Here’s the short version:
- Who it applies to: new construction or demolition projects larger than 500 sq. ft., and interior remodels/renovations larger than 2,500 sq. ft. — anything requiring a city permit.
- What’s required: at least 50% of all debris generated on-site (by weight) has to be reused or recycled, across a minimum of 3 different material types — concrete, asphalt, masonry, untreated wood, metal, and corrugated cardboard are the materials the city calls out specifically.
- When it’s due: this is the part that catches people off guard — a waste diversion plan has to be submitted with your permit application. This isn’t paperwork you file after the job wraps; it’s part of getting the permit in the first place.
Why This Is Worth Acting On Now, Not in August
The city has said it’s taking an education-first approach to enforcement, and some exemption details are still being finalized through public rulemaking. But the permit-application requirement doesn’t move — if your project needs a permit after September 1 and you haven’t planned for source-separated containers, you’re solving this problem at the worst possible time: during permitting, under a deadline, with a project waiting to start.
The projects that won’t feel this at all are the ones already set up to separate concrete, wood, metal, and cardboard into their own containers instead of one mixed dumpster. That’s a container-planning decision, and it’s a lot easier to make before the job starts than to retrofit once debris is already piling up mixed together.
How We Help
We already provide load-level weight documentation and diversion reporting for LEED submittals and Austin’s own C&D ordinance — the same infrastructure applies here. If you’re planning a Denver project that will need a permit after September 1:
- We’ll help you plan the right mix of labeled containers (concrete, scrap metal, general C&D) so source separation happens automatically, not as an afterthought.
- We provide weight tickets for every load, tracked by material stream, so you have the documentation ready when the city asks for it.
For the full breakdown of the ordinance — requirements, exemptions, and a diversion calculator — see our Denver LEED & Waste No More Ordinance guide.
