C-PACE financing matters because commercial and multifamily buildings need expensive upgrades at the exact moment many owners are dealing with tighter credit, higher insurance costs, aging systems, and pressure to cut utility bills.
For a hotel, apartment building, office conversion, warehouse, nonprofit facility, or mixed-use project, replacing HVAC equipment or adding solar can improve the asset, yet the upfront cost often stalls the work.
Commercial Property Assessed Clean Energy financing, better known as C-PACE, gives owners another path. It can fund eligible energy, water, renewable energy, and resilience improvements, then spread repayment over a long period through a voluntary property assessment.
EPA describes PACE as a tool for financing qualified energy, water, resilience, and public benefit projects through an assessment on the property tax bill.
What C-PACE Financing Means in Plain Terms
C-PACE is a form of property-based financing. Instead of treating the upgrade like a normal short-term construction loan or unsecured business loan, the repayment obligation is tied to the building through a special assessment.
In simple terms, an owner receives capital for eligible building improvements. The owner repays that capital over time, often alongside property tax payments or through a related assessment process, depending on local rules.
Virginia Energy explains that PACE can finance up to 100% of upfront clean energy project costs, with repayment made through a voluntary assessment on the property tax bill.
C-PACE is especially relevant for commercial and multifamily properties because many improvements have long useful lives.
Long-life building systems matter in every property category, which is why steel-frame housing providers such as Elythera homes emphasize durable structures, efficient materials, and construction methods designed around long-term value.
A chiller, roof, window system, solar array, high-efficiency boiler, heat pump system, or stormwater improvement can serve the building for years. Long-term repayment can better match the life of the improvement.
Why Commercial And Multifamily Owners Are Paying Attention
Energy costs are a large operating expense. The U.S. Energy Information Administration estimated that 5.9 million U.S. commercial buildings consumed 6.8 quadrillion BTUs of energy and spent $141 billion on energy in 2018.
Electricity and natural gas were the main sources, while space heating accounted for close to one-third of end-use consumption.
For multifamily projects, the logic can be even sharper. Owners may need to modernize heating, cooling, hot water, lighting, insulation, windows, elevators, roofs, and controls while trying to protect rent stability and project returns. A large rehab can become hard to pencil out when every line item competes for capital.
C-PACE does not make a weak project strong by itself. It can, however, help a viable project move forward by reducing upfront cash needs and matching repayment to long-lived improvements.
What Can C-PACE Usually Finance?
Eligible work depends on state law, local program rules, technical review, and the property type. Programs differ, so owners should never assume one state’s eligible list applies elsewhere.
Common categories include:
| Project Category | Common Examples | Why Owners Use It |
| Energy efficiency | HVAC, controls, LED lighting, insulation, windows | Lower operating costs and improve building performance |
| Renewable energy | Solar panels, sometimes storage when eligible | Produce power on-site and reduce grid exposure |
| Water efficiency | Low-flow systems, irrigation controls, water reuse measures | Cut water use and related utility expenses |
| Resilience | Flood protection, stormwater systems, wind hardening, elevated equipment | Reduce risk from weather and climate hazards |
| New construction | High-performance building systems and envelope measures | Fill part of the capital stack with long-term funding |
C-PACE programs may support multifamily residential properties, commercial buildings, industrial properties, and nonprofit properties. Eligible measures vary by sponsor, financing model, and local program rules.
Virginia’s program materials specify that C-PACE can help owners of commercial and multifamily buildings with 5 units or more reduce operating costs and improve property values.
Virginia adopted C-PACE legislation in 2009, amended the law in 2015, and launched a statewide program in September 2022 for local governments that choose to participate.
How C-PACE Fits Into A Capital Stack

In real estate finance, “capital stack” simply means the layers of money used to fund a project. A commercial project might include senior debt, sponsor equity, mezzanine debt, tax credits, grants, or preferred equity. C-PACE can become one additional layer.
For a ground-up multifamily project, C-PACE may finance eligible high-performance systems. For a hotel renovation, it may cover HVAC, insulation, lighting, and water systems. For an older office building being converted to apartments, it may help fund windows, mechanical systems, roof work, and resilience upgrades.
The appeal is clear: C-PACE can reduce the amount of sponsor equity or higher-cost financing needed. That can improve the project’s economics. The tradeoff is equally clear: the assessment becomes part of the property’s obligations, and senior mortgage lenders usually need to review and consent.
PACE obligations are secured by a property lien, and past-due PACE payments can have priority over mortgages in foreclosure, similar to other property tax assessments. For that reason, lender review matters.
Lender Consent Is A Central Step
Most commercial properties already have a mortgage or construction loan. Because a C-PACE assessment can affect lien priority for unpaid installments, existing lenders usually want a close look before approving it.
Lawrence Berkeley National Laboratory’s issue brief explains that mortgage holder consent is considered a best practice, even where every program does not require it.
The same brief describes how capital providers, local governments, program administrators, property owners, contractors, and mortgage holders may all play roles in the process.
For owners, the practical lesson is straightforward. Bring the mortgage lender into the conversation early. A lender may ask for:
- Eligible-cost calculations
- Energy or resilience reports
- Appraisal or value impact support
- Sources and uses
- Assessment repayment schedule
- Intercreditor or consent documentation
A late consent request can slow a closing. Early coordination gives the project a better chance of moving cleanly.
Why Local Rules Matter So Much
C-PACE exists because state and local governments authorize it. A property owner cannot simply choose C-PACE in any city or county. The state must have enabling legislation, and the relevant local government often must adopt an ordinance or join a statewide program.
Virginia is a useful example. State law created the framework, while local participation determines availability.
Virginia Energy says its statewide program was designed to give local governments a standard option instead of requiring each locality to build a program from scratch. The stated goal is faster and more equitable access to capital, especially in smaller jurisdictions.
EPA’s clean energy financing toolkit also lists C-PACE as a financing option that requires enabling legislation and can serve commercial, industrial, nonprofit, and multifamily sectors.
Market Growth Shows Strong Demand
C-PACE has moved from niche financing into a more visible part of commercial real estate. PACENation reports $9.717 billion in cumulative commercial PACE investment through December 2024, covering 3,581 commercial projects and supporting an estimated 122,000 job-years.
Its data also shows energy efficiency as the largest project category, followed by renewable energy, mixed projects, and resilience.
Project examples show how broad the market has become. Connecticut Green Bank recognized the Corbin District in Darien as a 2024 outstanding C-PACE project after Counterpointe provided $63.3 million in C-PACE financing, the largest C-PACE transaction in Connecticut at that time.
The mixed-use project used resilience measures, including permeable pavers for drainage, to access additional funding.
In Washington, D.C., DC Green Bank reported several recent PACE and C-PACE closings, including financing for an energy-efficient hotel, a new multifamily community, and a large office-to-residential conversion.
Where C-PACE Works Best
C-PACE tends to fit projects with a clear building-performance story and a long-term ownership or value plan.
It can be useful when improvements are required anyway, such as replacing failing HVAC equipment, upgrading an aging roof, or meeting performance standards during a major renovation.
Strong candidates often include:
- Multifamily rehab projects with major mechanical upgrades
- Hotels replacing HVAC, lighting, insulation, and water systems
- Office-to-residential conversions
- Mixed-use new construction with efficient systems
- Industrial buildings adding solar or energy controls
- Nonprofit facilities with limited upfront capital
The strongest cases connect capital needs with measurable asset benefits. Lower energy use, better resilience, improved tenant appeal, code compliance, and reduced maintenance risk all matter.
Main Risks Owners Should Weigh
C-PACE is useful, yet it is still debt-like capital with legal and financial consequences. Owners should review the repayment schedule, prepayment terms, transfer rules, lien structure, eligible-cost limits, and lender consent requirements.
The biggest issues usually fall into 4 areas:
- Availability: The property must sit in an active C-PACE jurisdiction.
- Consent: Mortgage lenders may decline, delay, or request changes.
- Sale or refinance: Buyers and future lenders may evaluate the assessment carefully.
- Project discipline: Savings projections and eligibility reports need credible support.
EPA notes that the assessment may stay with the property after a sale if the buyer agrees, while a seller may need to pay off the outstanding amount when transfer is not accepted.

The Bottom Line
C-PACE financing gives commercial and multifamily owners a practical way to fund building improvements that are often expensive, necessary, and hard to delay. It works best when owners treat it as structured real estate capital, not a quick rebate or generic green loan.
For the right project, C-PACE can lower upfront cash pressure, support better building performance, and help older properties stay competitive. The best results come from early lender coordination, careful eligibility review, and a clear plan for how the upgrades improve the asset.
