Denver's Brand New Construction Noise Law (February 2025)
On February 24–27, 2025, Denver passed the first major update to its construction noise ordinance in nearly two decades. The amendment to Denver Revised Municipal Code Chapter 36 introduces a revolutionary enforcement mechanism that fundamentally changes how DDPHE approaches construction noise violations. Instead of requiring sound measurement equipment and technical expertise, the new "plainly audible" standard allows enforcement based on whether a noise source is audible indoors at a residential window.
This change is significant. Previously, enforcement required DDPHE noise inspectors to measure actual decibel levels at the property line and compare those against the regulatory limits of 55 dBA during the day (7 AM to 9 PM weekdays) and 50 dBA at night. The new amendment preserves these dB limits but adds a subjective audibility test: if the noise source is perceptible indoors AND exceeds the dB limit, a violation can be enforced. Critically, video evidence is now sufficient—no dB meter required.
The ordinance also now permits anonymous complaints. Previously, complainants had to be named. This structural change means contractors can face enforcement action without knowing the identity of the complainant, reducing the possibility of complaint dismissal or litigation based on complainant credibility. Combined with the video evidence standard, this creates a low-friction enforcement pathway for DDPHE.
For Denver contractors, the February 2025 amendment is urgent. This is the FIRST substantive update to Chapter 36 construction provisions since 2008. The "plainly audible" test will inevitably lead to an increase in enforcement activity as DDPHE staff become familiar with the new toolset. Contractors must implement noise mitigation measures before the enforcement surge begins. The window to demonstrate proactive compliance is narrow.

Why Echo Barrier for Denver Construction Sites
Echo Barrier's portable acoustic barrier system provides independently tested noise reduction of up to 43 dB, as verified by AKRF, a nationally recognized acoustical engineering firm. Each panel weighs approximately 13 lbs, can be deployed in hours, and is reusable across multiple job sites. For Denver contractors facing the new 2025 ordinance and DDPHE's explicit barrier recommendation, Echo Barrier provides a documented, verifiable noise mitigation solution.
The AKRF test report demonstrates that Echo Barrier panels achieve Sound Transmission Class (STC) 30 performance in field conditions. This STC rating outperforms standard 1.5-inch marine plywood hoarding. The panels are lightweight enough to be installed by a two-person crew without heavy lifting equipment, and they distribute same day to Denver and throughout Colorado.
For contractors preparing for DDPHE compliance or demonstrating proactive mitigation, Echo Barrier provides the third-party documentation needed. When DDPHE Noise Program guidance cites "noise-reducing barriers" as the expected solution, having an independent lab report confirming the barrier's performance is decisive. The AKRF report serves as irrefutable evidence that the mitigation measure meets compliance expectations.
Performance claims vary by site conditions and installation.

DDPHE Noise Program Explicitly Recommends Noise-Reducing Barriers
The Denver Department of Public Health & Environment Noise Program publishes guidance on construction noise compliance. Within that guidance, DDPHE explicitly identifies "noise-reducing barriers" as a primary mitigation tool for construction sites near residential areas, schools, hospitals, and other noise-sensitive locations. This is not a passing suggestion but a documented compliance expectation.
Under Chapter 36, contractors operating near residential properties must maintain noise levels at 55 dBA during permitted hours (7 AM–9 PM on weekdays, 8 AM–5 PM on weekends) and 50 dBA during restricted hours. DDPHE's Noise Program guidance states that where noise sources exceed these limits (or are "plainly audible" indoors), noise-reducing barriers are the expected mitigation measure. Other solutions like work schedule modifications or equipment substitution are subsidiary approaches; barriers are the primary compliance mechanism.
This explicit recommendation from DDPHE provides regulatory cover for contractors choosing to deploy noise barriers. When a contractor reports that Echo Barrier system is deployed, DDPHE's own guidance supports the choice. Conversely, contractors who ignore the "noise-reducing barriers" recommendation and attempt other mitigation strategies risk appearing non-compliant with DDPHE guidance if a violation occurs.
$5,000-Per-Day Fines and Compounding Violations
Denver's Chapter 36 imposes a maximum fine of $5,000 per day for construction noise violations. Critically, each day of continued violation constitutes a separate offense. A contractor operating non-compliant equipment near a residential property for one week could face theoretical cumulative fines of $35,000 or more, depending on whether weekends are included and whether the violation is deemed continuous or repeated.
The daily accumulation structure creates urgent financial pressure to achieve compliance. Unlike some municipal codes where violations are episodic (a single fine per incident), Denver's daily counting mechanism means that compliance delays compound. Contractors who discover they are out of compliance and take three days to deploy corrective measures face three days of potential fines—and if DDPHE issued a complaint on day one, the contractor may be liable for all three days even after correction.
For projects with tight timelines and multiple construction phases, the $5,000/day fine structure makes Chapter 36 compliance a budgeting necessity. Many Denver contractors budget for noise barrier rental as routine project cost, similar to dust control or erosion management, recognizing that non-compliance is not an option.
Frequently asked questions
Denver DDPHE Noise Program guidance explicitly lists "noise-reducing barriers" as the primary compliance measure for construction near residential areas. Echo Barrier is a portable, certified solution that aligns directly with DDPHE expectations.
Echo Barrier reduces noise by up to 43 dB, as independently verified by AKRF. The panels achieve Sound Transmission Class (STC) 30 in field conditions, outperforming standard plywood hoarding. Panels weigh about 13 lbs each, are reusable, and distribute same day to Denver.
Denver permits construction during 7 AM–9 PM on weekdays and 8 AM–5 PM on weekends. After-hours construction near residential properties requires noise mitigation measures such as portable barriers to comply with Chapter 36.
Fines for Chapter 36 violations are up to $5,000 per day. Each day of violation constitutes a separate offense, so cumulative fines can escalate rapidly. For a week-long violation, cumulative exposure could exceed $35,000.
Denver DDPHE Noise Program explicitly recommends noise-reducing barriers for construction sites near residential areas, schools, hospitals, and other sensitive locations. While not technically mandatory, DDPHE's published guidance identifies barriers as the primary mitigation tool. Contractors should treat barrier deployment as a compliance expectation.
The February 2025 amendment introduces a "plainly audible" test: if a noise source is audible indoors at a residential window AND exceeds the dB limit, a violation can be enforced without equipment measurement. Video evidence is now sufficient. Anonymous complaints are also now permitted. This is the FIRST major update since 2008.
Denver Revised Municipal Code Chapter 36 governs construction noise control in the city. It establishes decibel limits of 55 dBA during the day (7 AM–9 PM on weekdays, 8 AM–5 PM on weekends) and 50 dBA at night. The February 2025 amendment added a "plainly audible" standard and video evidence enforcement mechanism. DDPHE enforces Chapter 36.
