What is commercial PACE financing? Commercial PACE (C-PACE) is a financing mechanism that lets building owners fund energy efficiency and clean energy upgrades with no upfront out-of-pocket cost. The loan is repaid through a special assessment on the property tax bill over 20–30 years. Because the assessment stays with the property—not the borrower—C-PACE typically offers lower rates (5–8%) and longer terms than a conventional commercial loan. It is available for commercial, industrial, and multi-family properties in 35+ states as of 2026.

What Is C-PACE Financing?
Commercial PACE financing (C-PACE) is a loan program authorized at the state level that allows owners of commercial, industrial, agricultural, and multi-family (5+ units) properties to finance energy efficiency, renewable energy, and water conservation improvements. Unlike a bank loan, the financing is secured by a special assessment on the property—meaning it is tied to the building, not the borrower’s personal or corporate credit.
The mechanism works through local government: the state passes enabling legislation, the local municipality or a state-appointed program administrator oversees the program, and a PACE lender funds the project. The lender is repaid through a line item on the property’s annual tax bill. If the property is sold, the assessment typically transfers to the new owner—which is both a benefit (the current owner doesn’t need to recoup costs before selling) and a consideration for buyers (they inherit the repayment obligation).
The program was first authorized in California in 2008 and has since expanded to more than 35 states. Total C-PACE volume exceeded $8 billion by 2025, with annual originations growing at roughly 20–25% per year as commercial lenders, institutional investors, and building owners become more familiar with the structure.
How C-PACE Works: Step by Step
1
Determine Eligibility
Confirm your state has active C-PACE enabling legislation and that your property type qualifies (commercial, industrial, or multi-family 5+ units). Most programs require the property to be current on property taxes with no outstanding liens that would subordinate the assessment.
2
Define the Project
Identify qualifying upgrades: HVAC, solar PV, battery storage, building envelope (insulation, roofing, windows), LED lighting, EV charging, or water efficiency systems. Most programs require a technical report demonstrating energy savings or generation. An ASHRAE Level 2 energy audit is typically the starting point for this analysis.
3
Select a C-PACE Lender
Contact program administrators or lenders approved in your state. Major C-PACE lenders include Nuveen Green Capital, Petros PACE Finance, Counterpointe Sustainable Real Estate, and regional programs. Compare rates, terms, and fee structures. Request a term sheet once the project scope is defined.
4
Obtain Mortgage Lender Consent
Because C-PACE creates a senior or parity lien on the property, your existing mortgage lender must consent. Submit the proposed PACE assessment details to your lender’s consent desk. Most major banks, life companies, and CMBS servicers have standardized consent policies. Allow 2–4 weeks for this step.
5
Close and Fund
Once consent is received, the PACE assessment is recorded with the local government. Funding is typically disbursed at project completion or on a milestone basis for larger projects. The first assessment payment appears on your next property tax bill.
6
Repay Through Property Taxes
The annual assessment is added to your property tax bill for the term of the loan (typically 20–30 years). Many building owners find the annual payment is partially or fully offset by energy savings, making the effective cost of the upgrade near-zero or cash-flow positive from day one.

Key tradeoff: C-PACE’s longest-term structure (20–30 years) means lower annual payments but higher total interest paid over the life of the loan. For projects where energy savings are large and steady, this structure is often cash-flow positive. For projects with shorter useful lives (e.g., 10-year lighting upgrade), a shorter-term bank loan may be more economical despite higher payments.
Eligible Projects and Improvements
Most C-PACE programs fund improvements that result in measurable energy savings, renewable energy generation, water conservation, or resiliency improvements. Common eligible project types include:
Projects must typically be documented with an energy model or technical study demonstrating projected savings. Some programs accept ASHRAE Level 1 audits for simpler projects; larger or more complex projects usually require a Level 2 or Level 3 ASHRAE audit.
C-PACE Eligibility Requirements
While requirements vary by state and program, the typical C-PACE eligibility checklist includes:
Property type: Commercial, industrial, agricultural, or multi-family (5+ units). Most programs exclude single-family residential.
State authorization: The property must be located in a state with active C-PACE enabling legislation and a local program.
Current on taxes: No delinquent property taxes at the time of application. Tax liens disqualify most applicants.
Sufficient equity: Most programs cap the PACE assessment at 25–35% of the property’s assessed value. Some require a minimum equity cushion (e.g., 20% LTV headroom).
Mortgage lender consent: Required in most states when a mortgage exists on the property.
Qualifying project: At least one eligible improvement with documented energy or water savings.
State availability matters: C-PACE is state-by-state. Major markets like California, New York, Texas, Florida, and Colorado have active programs. Some states have enabling legislation but no active programs yet. Always verify your state’s current program status before planning a project.

Combining C-PACE with Other Incentives
C-PACE is most powerful when stacked with other incentives. Common combinations include:
C-PACE + 179D tax deduction: The 179D deduction (up to $5.94/sqft for commercial buildings) rewards energy performance and is fully compatible with PACE financing. See our 2026 Energy Incentives Guide for deadline details.
C-PACE + IRA Section 48 Investment Tax Credit: Solar ITC (30%) can be claimed on a PACE-financed solar installation, significantly reducing the effective cost of the project.
C-PACE + utility rebates: State and utility rebates (DSIRE.org has the full database) can reduce project cost, which reduces the PACE principal and total interest paid.
C-PACE + ENERGY STAR certification: Energy upgrades funded through C-PACE often push buildings into ENERGY STAR-certifiable territory. A certified building commands higher rents and lower cap rates. See our ENERGY STAR Certification Guide.
Frequently Asked Questions
Commercial PACE (C-PACE) is a financing mechanism that lets building owners fund energy efficiency and clean energy upgrades with no upfront cost. The loan is repaid through a special assessment on the property tax bill over 20–30 years, secured by the property rather than the borrower’s credit. Available in 35+ states for commercial, industrial, and multi-family (5+) properties.
C-PACE interest rates in 2026 typically range from 5% to 8%, fixed for 20–30 years. Rates vary by state, program, lender, project size, and property type. Because the assessment is secured by a real property tax lien (considered lower risk than unsecured commercial loans), PACE rates are generally 2–4 percentage points lower than a comparable commercial term loan.
Yes, in most cases. C-PACE creates a lien on the property that in many states is senior to or parity with the mortgage. Most lenders require written consent (lender acknowledgment) before the PACE assessment is recorded. Major banks and institutional lenders have standardized PACE consent policies. Allow 2–4 weeks for this step. Properties without an existing mortgage do not require consent.
Eligible C-PACE projects typically include: HVAC upgrades, solar PV, battery storage, building envelope improvements (insulation, roofing, windows), LED lighting, EV charging infrastructure, water efficiency systems, and seismic or resiliency upgrades (select states). Projects must demonstrate measurable energy savings or renewable energy generation. Most programs require a technical study or energy audit as documentation.
Most C-PACE programs have a minimum project size of $100,000–$250,000. Program administrative costs make smaller projects uneconomical. Maximum loan amounts are typically capped at 25–35% of the property’s assessed value. Typical commercial projects range from $500,000 to $5 million; portfolio transactions often exceed $10 million.
Yes. C-PACE financing and 179D deductions are fully compatible. C-PACE covers 100% of project costs at closing; 179D (up to $5.94/sqft) provides a federal tax deduction based on energy savings achieved. Together, they can make a major energy upgrade effectively cost-neutral. Always confirm 179D eligibility and qualification requirements with a licensed tax professional before project completion. The current 179D sunset deadline is under legislative review—see the 2026 Incentives Guide for current status.
C-PACE assessments typically transfer with the property at sale. The new owner assumes the remaining repayment obligation through the annual property tax assessment. This can be negotiated in the purchase agreement (seller may pay off the assessment or reduce the price accordingly). Buyers should always request a title search that identifies any PACE assessments before closing. Some buyers view inherited PACE as a positive if the energy savings are larger than the remaining assessment payments.
The C-PACE process typically takes 60–120 days from initial application to funding, depending on project complexity and lender consent timing. The steps are: project eligibility and scope review (1–2 weeks), underwriting and term sheet (2–4 weeks), lender consent (2–4 weeks), closing and recording (1–2 weeks), and funding at or shortly after project completion. Streamlined programs for simpler projects can close in 45 days.
