Colorado Wildfire Resiliency Code (CWRC)

The Colorado Wildfire Resiliency Code (CWRC) is a new statewide standard, adopted July 1, 2025, requiring fire-resistant building features—like Class A roofing, ember-resistant vents, ignition-resistant or noncombustible exteriors, and defensible space (cleared vegetation zones around homes)—in wildfire-prone Wildland-Urban Interface (WUI) areas.

It mainly applies to new construction, additions, and major remodels (not retroactively forcing changes on untouched existing homes). Cities and counties in WUI zones had to adopt it (or equivalent rules) by April 1, 2026, with enforcement following soon after.

In Ouray, Community Development Director Dan Murphy recommended without any qualms that the Ouray City Planning Commission pass this on February 2, 2026, during discussions and an open house at City Hall. He presented it as straightforward and beneficial for safety, focusing on practical steps like clearing vegetation, using non-combustible materials, and maintaining roofs/gutters to protect homes and the community.

Yet this statewide "one-size-fits-all" code often makes little sense when applied rigidly to a small, historic mountain town like Ouray. We already have strong local wildfire rules (Ouray County's Section 16 regulations, in place since 1997 and updated through 2022) that require similar hardening and defensible space for new or improved structures—plus our 2025 Community Wildfire Protection Plan tailors strategies to our steep terrain, dense forests, and limited resources. Imposing the CWRC as is adds redundant bureaucracy, potential cost hikes (5-20%+ for compliant materials), and strain on our tiny staff/budget without state funding support—despite Colorado law (C.R.S. § 29-1-304.5) making unfunded mandates optional.

The push for adoption overlooks how Ouray's existing measures already address much of the risk effectively. Our Concerns About the CWRC in Ouray:

• It's an unfunded mandate: The state requires adoption and enforcement (e.g., extra permit reviews, inspections, training, and compliance for structural hardening/defensible space) without providing dedicated funding or reimbursement, violating C.R.S. § 29-1-304.5 which makes such mandates optional if unfunded.

• It's a blanket, one-size-fits-all approach that doesn't fit Ouray: The statewide code ignores Ouray's specific realities, tiny population (~1,000 in the city), historic buildings, tourism-driven economy, limited local staff/budget, and pre-existing strong local wildfire mitigation (Section 16 since 1997, revised 2020/2022), plus the 2025 Ouray County Community Wildfire Protection Plan (CWPP) that already prioritizes tailored risk reduction.

• Would decimate the trees and other greenery in Ouray: Defensible space requirements (ignition zones: 0-5 ft noncombustible, 5-30 ft reduced fuels with tree/shrub spacing and pruning, 30-100 ft extended zone) could lead to extensive tree thinning, crown separation (e.g., 10+ ft between crowns), and branch removal to reduce ladder fuels. In a heavily forested, scenic mountain town like Ouray, this risks altering the natural beauty, character, and environmental appeal that define the area and support tourism.

• Roundabout retroactivity for existing homes: The code claims no broad retrofits, but the 25% rule means homeowners cannot do major exterior updates (common for aging mountain homes, e.g., replacing worn siding/windows/roofs) without upgrading to fire-resistant materials and possibly addressing defensible space. This discourages improvements, raises costs (5-20%+ for compliant products), and creates a catch-22 where delaying work avoids the mandate but risks insurance hikes or safety issues.

• 25% threshold for roofing/siding/exterior walls acts as a de facto retroactive requirement: The CWRC (Section 101.6-101.7) triggers full compliance (e.g., Class A roofing, noncombustible/ignition-resistant materials, ember-resistant vents) if you replace 25% or more of the roof surface area, exterior walls/siding, or similar vulnerable elements. Minor patches or small repairs (<25%) are exempt, but many typical remodels (e.g., full roof replacement, re-siding a significant portion of the house, or window upgrades affecting exterior walls) easily hit or exceed this, forcing the upgraded parts, or potentially the whole structure, to meet new wildfire hardening standards.

• Substantial alterations/additions compound the issue: Additions over 500 square feet (footprint increase) often require the entire home to comply with CWRC hardening and defensible space rules. Even without an addition, combining exterior work (e.g., new siding + windows + partial roofing) can cumulatively trigger "substantial remodel" status, pulling existing elements into compliance.

• Defensible space gets pulled in indirectly: When exterior remodels trigger hardening requirements, permitting often includes defensible space verification (ignition zones: 0-5 ft noncombustible, 5-30 ft reduced fuels with tree/shrub spacing/pruning). This is not forced on untouched homes, but a siding/roofing project could require a site plan review and vegetation management near the house, effectively creating retroactive maintenance obligations.

• Increased costs and economic strain: Could add 5-20%+ to construction/renovation expenses (e.g., noncombustible materials, ember-resistant features) in a high-cost mountain market, slowing development, worsening housing affordability for locals/workforce, and deterring tourism-related projects without state help.

• Duplication and loss of local flexibility: Overlaps or overrides Ouray County's effective existing regs (e.g., affidavits, deposits for defensible space), reducing local control over land use, permitting, and community-specific wildfire strategies that better suit Ouray's steep slopes and forested surroundings.

• Administrative burden on small government: Ouray's limited resources would face added workload (e.g., site plan reviews, appeals) without support, potentially causing permit delays or diverting funds from other priorities like emergency services or infrastructure.

• No proven benefit over current local measures: Ouray already has proactive tools (e.g., CWPP actions, West Region Wildfire Council involvement, grants for mitigation), and the CWRC adds layers without addressing gaps in a way that justifies the burden.

• No funding ineligibility risk from non-adoption: Declining full adoption does not block grants (e.g., Community Wildfire Defense Grants, CSFS funding, or FEMA aid), which focus on project merit and CWPPs, not CWRC compliance.

  
  

  What Actions We Ask the City Council to Take:

  • Review precedents from other counties (e.g., Montezuma's Resolution 31-2025 requesting state enforcement takeover; Otero's Resolution 2025-25 affirming non-implementation; Prowers' decline citing high costs; La Plata's calls for optional treatment; Mesa/Western Slope joint letters on unfunded mandates) and apply similar strategies here.

  • Invoke C.R.S. § 29-1-304.5 to formally treat the CWRC as optional absent state funding, protecting Ouray's budget and affirming local authority.

  • Consult additional legal counsel (e.g., county attorney) to evaluate options, confirm non-adoption's implications, and ensure decisions align with state law and Ouray's needs.

  • Take Ouray County's current wildfire mitigation plan (Section 16 and 2025 CWPP) and formally confirm whether we are already meeting or exceeding CWRC minimum requirements, e.g., through a side-by-side comparison of standards for roofing, siding, vents, defensible space zones, and triggers for new/additions/remodels, to determine if full adoption is unnecessary or if only minor tweaks are needed for compliance.

  • Hold public engagement (building on recent open houses, like the February 2, 2026, event) to gather resident input, educate on options, and build consensus for a practical, locally tailored wildfire safety approach.

  • Advocate to state officials (e.g., via letters/resolutions) for funding, exemptions for small/high-risk towns, or changes to make the CWRC equitable and sustainable for places like Ouray.

  • Be honest and transparent about CWRC's very real effects on a city like Ouray.
