Denver’s New Construction Recycling Requirements: What Homeowners Need to Know Before Starting a Remodel or Addition

Quick Answer

Beginning September 1, 2026, most residential construction, demolition, and major remodeling projects in Denver will be required to recycle or reuse a significant portion of construction debris rather than sending it to the landfill.

Projects subject to the new Universal Recycling and Composting Ordinance (URCO) must submit a Waste Diversion Plan before receiving a building permit, divert at least 50% of eligible construction waste by weight, and document compliance once construction is complete.

For homeowners, this is another reason why working with an experienced Denver Design-Build team can simplify permitting and project management from start to finish.

What Is Denver’s Universal Recycling and Composting Ordinance (URCO)?

In 2022, Denver voters overwhelmingly approved the Waste No More initiative to reduce landfill waste and increase recycling throughout the city. The City and County of Denver later adopted implementation rules through the Universal Recycling and Composting Ordinance (URCO), providing a framework for how construction and demolition waste will be managed.

Beginning September 1, 2026, many residential and commercial construction projects will be required to incorporate recycling and material recovery into their construction process.

The goal is straightforward: divert reusable materials away from landfills while encouraging more sustainable building practices throughout Denver.

Which Residential Projects Are Affected?

For homeowners, URCO will apply to many of the projects Sustainable Design Build completes every year, including:

• Home additions larger than 500 square feet
• Custom home construction
• Detached garages and many ADUs
• Demolition projects exceeding 500 square feet
• Interior remodels larger than 2,500 square feet
• Most new residential construction requiring qualifying building permits

Smaller remodeling projects typically fall outside these requirements, although individual permit circumstances may vary.

What Contractors Must Do Beginning September 1, 2026

Projects covered under URCO will require several additional steps before and during construction.

Submit a Waste Diversion Plan

Before a qualifying building permit is issued, applicants must submit a Waste Diversion Plan describing how construction debris will be recycled or reused throughout the project.

Pay a Refundable Performance Security Deposit

Permit applicants must provide a performance security deposit before permit issuance.

Once the project successfully meets the ordinance’s requirements and documentation is submitted, the deposit is eligible for a full refund.

Divert at Least 50% of Construction Waste

Covered projects must divert at least 50 percent by weight of debris from three covered material categories through recycling or reuse rather than disposal.

Depending on the project, this may include materials such as:

• Wood
• Concrete
• Asphalt
• Metal
• Drywall
• Cardboard
• Other recyclable construction materials

Contractors will need to coordinate with approved recycling facilities and waste haulers to document diversion throughout construction.

Submit Final Documentation

When construction is complete, documentation must be provided demonstrating compliance with the Waste Diversion Plan and recycling requirements.

Will Every Project Be Required to Meet the Full Diversion Standard?

Not necessarily.

Denver recognizes that some construction sites present unique challenges.

Applicants may request:

• Modified diversion requirements because of site-specific conditions
• Reduced performance security deposits due to documented economic hardship

These accommodations acknowledge that not every project can realistically recycle the same volume or types of construction debris.

What This Means for Homeowners

While these new requirements primarily affect contractors, homeowners should expect several small changes during the planning process.

Your builder may discuss:

• Additional waste sorting procedures on-site
• Recycling containers alongside traditional dumpsters
• Material tracking throughout construction
• Updated permitting documentation
• Coordination with recycling facilities during demolition

For homeowners, these changes should largely occur behind the scenes when working with an experienced Design-Build contractor.

Why Design-Build Makes Compliance Easier

Construction regulations continue to evolve across the Denver metro area.

Over the past several years, homeowners have already experienced changes involving:

• Updated building codes
• Energy efficiency requirements
• Historic district reviews
• Stormwater management
• Permitting procedures
• Waste diversion regulations

Working with an integrated Design-Build firm means these requirements are coordinated under one team rather than leaving homeowners to navigate changing regulations themselves.

At Sustainable Design Build, permitting, pre-construction planning, estimating, scheduling, and construction management are handled together, helping projects remain organized while adapting to new municipal requirements like URCO.

If you’re planning a Denver home addition, whole-home remodel, custom home, or ADU, understanding permitting requirements early can help reduce delays and avoid unexpected surprises.

Recycling Requirements Are Becoming Part of Modern Construction

Construction waste has long represented one of the largest contributors to landfill volume nationwide. By encouraging recycling and reuse of building materials, Denver joins a growing number of municipalities implementing construction waste diversion programs.

Although these requirements introduce additional documentation, they also encourage more efficient material management and help reduce unnecessary disposal throughout the construction process.

As contractors, suppliers, recycling facilities, and homeowners become familiar with the ordinance, compliance should become another standard part of the construction process, much like permitting and inspections are today.

Planning a Remodel or Addition in Denver?

Whether you’re building a custom home, adding a second story, constructing an ADU, or remodeling your existing home, understanding current permitting requirements is an important part of a successful project.

Sustainable Design Build stays current with evolving Denver building regulations so homeowners can focus on their project rather than navigating changing municipal requirements alone.

If you’re considering a residential construction project, our team can guide you through design, permitting, budgeting, and construction while helping ensure your project meets the latest City and County of Denver requirements.

Frequently Asked Questions

When does Denver’s Universal Recycling and Composting Ordinance take effect?

The construction and demolition requirements become effective September 1, 2026, for qualifying building permit applications.

Does URCO apply to home additions?

Yes. Home additions larger than 500 square feet generally fall under the ordinance and must meet applicable waste diversion requirements.

Are interior remodels affected?

Interior remodels larger than 2,500 square feet are generally subject to the ordinance.

What percentage of construction waste must be recycled?

Covered projects must divert at least 50% by weight of debris from three covered material categories through recycling or reuse.

Do homeowners need to submit the Waste Diversion Plan themselves?

In most Design-Build projects, your contractor manages permitting documentation, including required waste diversion planning and final compliance documentation as part of the permitting process.
