PACE + ITC Stacking: The Commercial Energy Upgrade Financing Stack
Property Assessed Clean Energy (PACE) financing and the Investment Tax Credit (ITC) are a uniquely powerful combination. PACE covers upfront project costs through long-term property-tax-based financing — and because PACE is a loan rather than a grant, it does not reduce the ITC eligible basis. The result: a developer gets ITC credits on the full project cost, including the portion financed by PACE, without putting in the underlying equity.
What Is PACE Financing?
Property Assessed Clean Energy (PACE) financing allows property owners to finance energy efficiency and renewable energy improvements through a voluntary property tax assessment. The assessment is repaid over 5–30 years through the property tax bill, and transfers with the property upon sale.
Key characteristics of C-PACE (Commercial PACE):
- Long-term, fixed-rate financing (typically 5–30 years at 5–9% rates)
- No personal guarantee required — secured by the property assessment
- Covers 100% of eligible improvement costs (subject to LTV limits)
- Senior lien position in property tax priority (requires lender consent)
- Transfers with property upon sale — no payoff required at closing
- Available for commercial, industrial, multifamily, and mixed-use properties
C-PACE requires state enabling legislation and an active local program, so availability depends on where the property is. Programs are run by state or local PACE administrators, and private capital providers originate and fund the assessments.
Why PACE + ITC Is Such a Powerful Combination
The critical legal distinction: PACE is debt financing, not a grant or government rebate. Under IRS rules, grants and forgivable loans reduce the eligible basis of a project for ITC purposes. PACE does not — because it is a fully repayable obligation.
This means a developer can use PACE to finance 60–80% of a project's upfront cost, while still claiming the ITC on the entire project cost (including the PACE-financed portion). The equity contribution required is reduced dramatically, while the ITC credit value remains at the full project level.
Example: $2M Commercial Solar + Storage Project

With PACE + ITC
Timing matters: the ITC is claimed for the tax year the system is placed in service, and transfer proceeds arrive only after that. In both scenarios the developer must fund the ITC portion during construction with equity or a bridge loan; the bottom lines show the position once the ITC is monetized. In the PACE scenario, the developer funds the $400K not covered by PACE during construction, then is $200K cash positive after the $600K ITC. The solar portion of the ITC also requires construction to have begun by July 4, 2026, or the system to be placed in service by December 31, 2027 (One Big Beautiful Bill Act).
Top C-PACE States in 2026
| State | Program Status | Notes |
|---|---|---|
| California | Active (CSCDA/CalPACE) | Major market; covers commercial property types |
| New York | Active in participating municipalities | Availability depends on the municipality; multifamily eligible |
| Florida | Active (multiple administrators) | Major market for commercial; hurricane resilience improvements included |
| Colorado | Active (statewide) | One of first states; well-developed market; industrial eligible |
| Texas | Active (Houston, Dallas, Austin) | Municipal adoption; strong for commercial solar and storage |
| Connecticut | Active (C-PACE CT) | High participation rates; clean energy priority; state-backed program |

Lender Approval Considerations
C-PACE requires written consent from the first mortgage lender because the PACE assessment is senior to the mortgage in property tax priority. Most institutional lenders approve PACE with the following conditions:
Energy-related improvements only
PACE must fund qualifying energy, water, or resilience improvements — not general property improvements.
Reasonable PACE-to-value ratio
Most lenders cap combined senior debt + PACE at 70–80% of stabilized property value. PACE amounts exceeding this create lender resistance.
Formal lender consent agreement
The PACE administrator provides a standardized lender consent agreement, which many lenders have processed before.
Debt service coverage analysis
Lenders want to see that the property cash flow can support both the senior debt service and the PACE assessment payment.
Frequently Asked Questions
Does PACE financing reduce the ITC eligible basis?
No. PACE financing does not reduce ITC eligible basis because PACE is a loan (repaid through property tax assessment), not a grant or rebate. The ITC is calculated on the full project cost regardless of how the project is financed. This is one of PACE's most significant advantages over grant programs.
In which states is commercial PACE available?
Commercial PACE (C-PACE) requires state enabling legislation and an active local program, so availability depends on where the property is. Established markets include California, Florida, New York, Colorado, Texas, and Connecticut. Programs vary significantly by state in terms of eligible improvements, LTV limits, and lender approval requirements, so confirm with the local program administrator.
Does my lender need to approve PACE financing?
Yes. C-PACE requires lender consent because the PACE assessment is a senior lien on the property (ahead of the mortgage in property tax priority). Most institutional lenders approve PACE if the project is energy-related, the PACE amount is reasonable relative to property value, and a formal lender consent agreement is signed.
What improvements qualify for PACE financing?
Eligible improvements vary by state but typically include: solar PV systems, battery storage, HVAC upgrades, building envelope improvements (windows, insulation, roofing), LED lighting, EV charging infrastructure, and water efficiency measures. Some states include seismic and storm resilience improvements.
Can PACE be used in a LIHTC affordable housing deal?
Yes, but it requires state Housing Finance Agency (HFA) approval in addition to lender consent. HFA policies on C-PACE differ, so confirm with the HFA in your state. The assessment must be structured so that it does not conflict with LIHTC compliance requirements.
