Colorado raised the ceiling on C-PACE—and it's worth a close look if you're financing or developing commercial real estate in the state.

Under the updated Colorado C-PACE Program Guide (v6.0, effective April 2026) and SB25-182, projects meeting enhanced energy performance standards can now qualify for Total Assessment-to-Value (TATV) thresholds well above the historical ~35-40% range, up to 75% TATV with written Program approval. That's a meaningful jump in available proceeds for qualifying deals.

To get there, projects need to step up performance: compliance with the 2024 International Energy Conservation Code (IECC), the Colorado Model Electric Ready and Solar Ready Code, or the new Colorado Model Low Energy and Carbon Code. Eligible measures have also expanded to explicitly include resiliency improvements (e.g., indoor air quality systems, battery energy storage systems, backup power systems, storm hardening, flood mitigation, seismic upgrades, wildfire resistance), and embodied carbon improvements. This means structural and enclosure costs like foundations, structural systems, and cladding can now be financed through either a materials-based pathway (low-GWP concrete, steel, etc.) or a whole-building carbon-intensity pathway. That's a real shift from C-PACE's traditional use case of MEP (mechanical, electrical, and plumbing), with real upside for adaptive reuse and office conversion plays. A good use case could be to convert old or underused buildings, such as turning a vacant office tower into apartments, hotel space, senior or assisted living, or another use, since those projects often require large-scale, expensive systems overhauls that go well beyond simple MEP swaps. With the expanded scope, developers taking on these conversions can now tap C-PACE to help fund more of that heavier lift, making adaptive reuse and office conversion projects more financially feasible.

For capital providers and construction lenders, the bigger potential C-PACE tranche raises the stakes on structuring: mortgage holder consent remains a hard statutory requirement, lien priority and escrow mechanics need fresh attention at higher assessment levels, and may require extra diligence (environmental product declarations, life-cycle assessments, independent third-party reviewer reports) to be built into underwriting timelines early rather than late.

As a C-PACE finance attorney, I often work with clients seeking C-PACE financing and finance partners delivering capital.
