Residential PACE is not C-PACE. Here is the difference.

Search for problems with PACE financing and the results are brutal: a state attorney general settlement over consumers being impersonated on financing forms, and a federal agency writing a rule to bring the product under mortgage law. If you are a commercial property owner who has just been pitched something called C-PACE, that reading list is a reasonable place to stop and walk away.

It is also the wrong reading list. Two products share the acronym. They share a mechanism — repayment through an assessment on the property tax bill — and they share very little else. The consumer record is real and it is bad. It is a record of the other one.

Two programmes, one acronym

Residential PACE (R-PACE) finances home improvements for individual homeowners: the Consumer Financial Protection Bureau’s rule defines a PACE transaction as financing to cover the costs of home improvements that results in a tax assessment on the real property of the consumer. Its footprint is narrow. PACENation’s programs page states that residential PACE is currently offered in California, Florida and Missouri — fetched 5 September 2026, though that page does not publish an as-of date of its own.

Commercial PACE (C-PACE) finances work on commercial property. The C-PACE Alliance’s guide for mortgage lenders describes the eligible universe as commercial, industrial, retail and multifamily properties with five or more units. The US Department of Energy describes long 10 to 20 year terms, not to exceed the useful life of the installed equipment, across a scope that runs from energy reduction and onsite generation through water efficiency, seismic retrofits, wind resistance, flood mitigation and stormwater management.

Same plumbing. Different borrower, scope and rules.

Who is on the other side of the table

This is the difference everything else follows from.

Residential PACE was sold to homeowners, and the EPA records consumer advocates raising concerns about deceptive or high-pressure sales tactics by contractors, high tax bills, the risk of foreclosure, and issues with refinancing or selling. The California Attorney General and the Federal Trade Commission announced a settlement with Ygrene Energy Fund on 28 October 2022 alleging that the company failed to secure consumers’ express informed consent to use their homes as collateral to secure PACE financing, instead impersonating consumers on calls or forms; that property owners were rushed through Ygrene’s lengthy contract; and that they were given misrepresentations about their ability to refinance or sell their home before fully paying off the PACE financing.

Commercial C-PACE differs in a checkable way: before it closes, a third party with money at stake reviews it and agrees.

The consumer protection regime applies to one of them

Here is the cleanest way to see that these are separate products: federal consumer law now covers one and not the other.

The Consumer Financial Protection Bureau’s final rule amends Regulation Z to apply Truth in Lending Act requirements to residential PACE. It became effective 1 March 2026. It applies ability-to-repay requirements, including — for consumers who pay their property taxes through an escrow account — a requirement that the creditor consider certain monthly payments it knows or has reason to know the consumer will have to pay into that escrow account, as an additional factor in the repayment ability determination. It provides new model Loan Estimate and Closing Disclosure forms designed specifically for PACE transactions. It states that a PACE transaction is not a qualified mortgage. And in the Bureau’s own summary of the rule, Home Ownership and Equity Protection Act requirements as implemented in Regulation Z may apply to PACE transactions that are high-cost mortgages.

The rule survived challenge. On 12 February 2026 the US District Court for the Middle District of Florida upheld it, holding that PACE financing constitutes credit under TILA because it arises from a voluntary contractual financing arrangement, even though repayment is collected through property tax assessments.

None of that is written for a commercial deal. The rule is built around home improvements and consumers; a retrofit of an income-producing building is neither. The protections are not yours — and neither is the record of abuse that made them necessary.

That cuts both ways. Nobody will send you a Closing Disclosure or run an ability-to-repay test on your behalf. The commercial market’s safeguard is a different one, and it is structural.

Lender consent: the safeguard residential PACE did not have

The single biggest structural difference is that in commercial C-PACE, your existing mortgage holder is normally asked to agree first.

The C-PACE Alliance states that prior to closing, existing mortgage holders on the property must consent to the C-PACE financing, and describes that consent as functioning as a double-check on the project viability. The Department of Energy puts it the same way: for properties with a mortgage, mortgage lender consent is usually required before C-PACE can move forward — adding, in the same breath, that this can be difficult and time-consuming to obtain. Philadelphia’s programme requires property owners to receive consent from all mortgage and lien holders before the Philadelphia Energy Authority approves a project’s final application.

Now look at what happened on the residential side. In a statement dated 6 July 2010, the Federal Housing Finance Agency said that first liens established by PACE loans are unlike routine tax assessments and pose unusual and difficult risk management challenges. Among the measures it directed Fannie Mae and Freddie Mac to take: adjusting loan-to-value ratios to reflect the maximum permissible PACE loan amount available to borrowers in PACE jurisdictions, tightening borrower debt-to-income ratios to account for additional obligations associated with possible future PACE loans, and ensuring that loan covenants require approval or consent for any PACE loan.

Read that last item again. The federal regulator of the mortgage market, confronting a product that had put a senior claim ahead of its enterprises’ loans, reached for exactly the mechanism commercial C-PACE builds in from the start.

The Bureau’s own research is the other half of the picture. Its May 2023 report on PACE financing and consumer financial outcomes, documenting findings from July 2014 through June 2020, concluded that PACE loans cause an increase in negative credit outcomes, particularly mortgage delinquency. A product that damages the performance of the mortgage behind it is precisely what a consent requirement exists to prevent.

What actually shows up, and what happens when you sell

In both products, repayment runs through the property tax assessment rather than through a note you service monthly to a lender. The EPA describes PACE as a financing tool that allows property owners to finance the upfront cost for qualified energy, water, resilience and public benefit projects with funding through a voluntary assessment on the property tax bill, and notes that commercial PACE programmes are the most prevalent type of PACE policy and program in the United States.

On a sale, the obligation does not follow you out the door. The Department of Energy states that C-PACE assessments are linked to the property and automatically transfer to a new owner upon the sale of the property. The EPA describes the assessment as staying with the property in the event of a sale, assuming the buyer agrees to the transfer — and that qualifier is the practical reality. The associated lien will run with the land, as White and Williams put it in a 5 February 2019 alert for commercial real estate lenders, which means your buyer inherits an obligation and will price it — sometimes favourably, because they also inherit the improvements, sometimes not.

On the residential side this same feature sits behind two of the concerns the EPA records consumer advocates raising: issues with refinancing or selling, and the risk of foreclosure. On a commercial deal it is something to price during diligence rather than discover at closing — a negotiation, not an ambush.

So what are the commercial risks, honestly

This is not a defence brief. If the residential record is not your risk, here is what is.

Your lender can say no. A mortgage holder that does not want a senior assessment ahead of its loan is entitled to that view, and the decision is theirs. The Department of Energy calls consent difficult and time-consuming to obtain, which tells you how to sequence it: have that conversation before you have a term sheet. We have written that conversation out from your side of the table.

Delinquent payments sit on par with property taxes. The C-PACE Alliance describes the claim for delinquent C-PACE payments as on par with property taxes. That priority is real, and it is the reason consent matters. The mitigating structure is that the whole balance does not come due: the Alliance states that in an enforcement or foreclosure only delinquent payments may be collected, and White and Williams write that in most jurisdictions C-PACE loans are non-recourse to the borrower or property owner and cannot be accelerated. Delinquent instalments are senior. The unpaid future balance is not sitting there ready to be called. Note the qualifier — in most jurisdictions — and have your counsel confirm it for the state your property is in.

It is long, and it is on the property. The Department of Energy’s range of 10 to 20 years is a long time to carry an assessment on an asset you may want to sell in five, whatever the buyer ultimately makes of it.

The foreclosure case law was thin as of 2019. The same 5 February 2019 White and Williams alert observed that although C-PACE loans have existed since 2009, there had not been a reported case relating to a foreclosure of a C-PACE loan, and treated the super-priority given to C-PACE assessments as a factor lenders should evaluate on a deal by deal basis. We have not found a source establishing where that record stands today, which is itself worth knowing before you rely on precedent.

And sometimes it is simply the wrong product. Speed, small deal size, or a scope outside the state programme’s eligible categories can each make a straight bank loan or a bridge loan the better answer, and we say so when they do. We place these; we do not originate them, and there is no version of this where we are better off talking you into the wrong one.

The short version

If the PACE horror stories made you nervous, that was the correct instinct applied to the wrong product. What you read about was sold to homeowners, and is now regulated under federal mortgage law because of it. What you are being offered is an assessment on a commercial building that your existing lender is normally asked to sign off on before it exists.

Then have the lender conversation early. That is the one that decides it.
