CPACE Financing California: How Commercial PACE Works for Solar

CPACE — Commercial Property Assessed Clean Energy — is a California financing structure specifically designed for commercial clean-energy projects (solar, storage, efficiency upgrades). It's repaid via an assessment on the property tax bill rather than as a conventional loan. Terms are set by the PACE administrator, and the obligation stays with the property if you sell. For commercial property owners evaluating how to pay for solar, CPACE is worth understanding alongside direct purchase, lease, and PPA.

How CPACE Works

The mechanics: your property's taxing authority places a special assessment on the property equal to the financed amount. You repay the assessment via your property tax bill over the financing term, which the administrator sets. The financing is secured by the assessment on the property. If you sell the property, the remaining assessment stays with the property and transfers to the buyer.

Because CPACE is property-secured rather than personal/corporate-credit-secured, it's structurally closer to a mortgage than to a conventional business loan. Approval is based on the property's loan-to-value, existing mortgage consent (if applicable), and the project's energy-savings economics.

The legal basis is state law. Streets and Highways Code §5898.20 lets a public agency designate an area where property owners may enter voluntary contractual assessments to finance distributed generation renewable energy and energy or water efficiency improvements, and §5898.12 states the Legislature's intent that this cover residential, commercial, industrial, agricultural and other real property (California Legislative Information, checked September 24, 2026).

California CPACE Program: CSCDA Open PACE

One statewide option is the CSCDA Open PACE program of the California Statewide Communities Development Authority, which covers residential and commercial property owners. CSCDA says a city or county must be a CSCDA member and adopt a resolution opting in to Open PACE before property owners there can use it; owners apply through one of the program's commercial PACE providers.

What CSCDA says its Open PACE administrators do, and what to confirm with them:

• •Financing: CSCDA says its administrators provide 100% financing for eligible projects
• •Rate and term: set by the administrator; ask whether the rate is fixed for the whole term
• •Structure: ask whether the financing carries any personal or corporate guarantee
• •Repayment: through the property tax bill; the assessment stays with the property
• •Size limit: ask the administrator how it caps the assessment against property value
• •Eligible uses: energy efficiency, renewable energy, water conservation and seismic improvements, per CSCDA
• •Local availability: confirm your city or county has opted in

Who CPACE Fits

Commercial property owners with long-term hold horizons. A long term only makes sense if you expect to own the property long enough for the bill reductions to cover the PACE assessment. If you're planning to sell soon, the assessment stays with the property — which is fine but makes your sale more complex.

Property owners who want property-secured financing. CPACE is secured by an assessment on the property. For owners who don't want a conventional business loan, that can be useful; confirm the guarantee and balance-sheet treatment with the administrator and your accountant.

Property owners whose existing mortgage lender consents. A PACE assessment is collected with property taxes, so a mortgage lender will usually want to approve it; getting that consent is one of the main hurdles before CPACE funds.

How to Apply

CPACE applications go through PACE administrators (third-party companies that originate PACE loans in partnership with CSCDA Open PACE or other California PACE districts). Your commercial solar EPC typically has relationships with multiple PACE administrators and can introduce you. The process:

1. Apply through a PACE administrator with property financials and project specs
2. Get preliminary underwriting
3. Obtain existing mortgage lender consent (most important gate)
4. Close the PACE assessment (paperwork is routed through the county recorder)
5. Project funds disburse to the EPC and construction begins

Ask the administrator for its expected time from application to funded close, and build it into the project schedule.

Check the amount before you finance it

C-PACE finances a project cost; it does not set one. The assessment runs with the property for the whole term, so the figure it is written against matters more here than under a structure you can refinance out of. Read the quoted amount against commercial solar cost per watt in California, which gives the published per-watt figures by system size and the date they were checked.
