How Does PACE Financing Work: Projects, Repayment, Protections

PACE financing, short for Property Assessed Clean Energy, works by letting a property owner pay for qualifying energy, water, or disaster-resilience upgrades through a special assessment added to the property tax bill. The money for the project comes from a PACE lender or program administrator, a lien for that amount is recorded against the property, and you repay it over a term that can run from about 5 to 30 years. The debt attaches to the real estate rather than to you personally, so it travels with the property if you sell. More than 38 states and the District of Columbia have enacted enabling legislation, though which type of PACE you can actually use, and under what rules, depends heavily on where the property sits and whether it’s commercial or residential.

The Basic Mechanics

A PACE assessment is structured as a special assessment, the same category local governments have long used to pay for sidewalks, sewer connections, and similar improvements. Once your project is approved and completed, the financed amount is recorded as a lien against the property and collected as a line item on your regular property tax bill, typically once or twice a year depending on your county’s schedule.

That tax-bill mechanism carries a consequence worth understanding up front: the PACE lien has the same priority as a property tax lien, which means it sits ahead of your mortgage. If the property were ever foreclosed on, the PACE assessment would be paid before the mortgage lender. This senior position is what lets PACE lenders offer longer terms and looser credit standards than an unsecured loan, but it’s also the source of nearly every complication PACE causes later.

Commercial PACE vs. Residential PACE

PACE splits into two separate markets with very different footprints. Commercial PACE (C-PACE) covers commercial buildings, industrial properties, multifamily buildings with five or more units, and nonprofit facilities, and it’s active in roughly 30 states plus D.C. It accounts for the bulk of PACE activity nationwide.¹

Residential PACE (R-PACE) covers single-family homes and small residential properties, and as of recent data it operates in only three states: California, Florida, and Missouri. If you’re a homeowner outside those states, R-PACE isn’t an option, regardless of what a contractor’s sales pitch may suggest.

What Projects Qualify

Eligible upgrades have to be physically attached to the property and deliver energy, water, or resilience benefits. The exact list is set by state and local law, but the categories are broadly consistent:

Energy efficiency work such as high-efficiency HVAC, insulation, lighting, and envelope improvements.¹
Renewable energy systems, including solar panels, solar water heaters, and small wind systems.
Water conservation measures like drought-resistant landscaping, low-flow fixtures, and water recycling.
Resilience and hardening upgrades, including impact-resistant windows, reinforced roofing, seismic retrofits, and wildfire safety work. Some states have expanded their statutes to add wildfire-resistant improvements in high-risk zones.²

Cosmetic work doesn’t qualify. Countertops, cabinetry, and room additions aren’t PACE-eligible, and some contractors bundle those items into the same proposal as qualifying work. Confirm each line item independently before you sign anything.

What It Takes to Qualify

PACE underwriting looks at the property more than at you. Specific thresholds vary, but several requirements show up across most programs:

The property needs enough equity that the PACE lien, combined with existing mortgage debt, stays within a set percentage of appraised value. Many programs want at least 10 percent equity remaining after the PACE lien is added.³
All property tax payments, charges, and assessments have to be current. Outstanding delinquencies disqualify you.⁴
No active bankruptcy. States like California and Florida typically require that the owner has been free of bankruptcy for four to five years.⁵
Clear title, with no involuntary liens or other encumbrances that would threaten the PACE assessment’s priority.
Assessment caps in some states. California requires that total annual property tax payments including the PACE assessment stay under 5 percent of the property’s value. Florida caps the total PACE lien at 20 percent of home value.⁶

Personal credit matters less here than it would for a home equity loan, because the lien is secured by real estate. That said, a pending federal rule discussed further below would push residential PACE closer to standard mortgage underwriting, with verified income and debt review.

How the Application and Funding Flow

You don’t apply through a bank. PACE runs through a program administrator or your local government’s PACE portal, with a contractor registered with the program driving most of the paperwork.

The sequence usually starts with a detailed quote from a registered contractor that spells out the qualifying work, costs, and the contractor’s license and insurance. You then submit an application to the administrator along with a recent property tax statement, documentation of your existing mortgage balance so equity can be verified, and the contractor’s proposal. Once approved, the administrator authorizes the contractor to start work.

You pay nothing out of pocket during construction. After installation, the program verifies that the work matches the proposal, pays the contractor directly, and records the financed amount, including program fees, as a lien against the property. The assessment shows up on the next property tax bill issued after certification.

Fees vary. Some administrators charge a flat application fee; others charge a percentage of project cost, plus a recurring annual administrative charge.⁷ Those fees get rolled into the assessment, so you’re financing them along with the project.

What Repayment Looks Like

Repayment terms generally run between 5 and 20 years, with some programs allowing up to 30, and the term cannot exceed the useful life of the improvement.⁶ Residential PACE interest rates typically fall in a range of roughly 6 to 9 percent, and commercial rates can run lower. Rates are usually fixed for the life of the assessment.

Because payment arrives through your property tax bill, it isn’t a monthly debit. You either budget for a lump sum once or twice a year or have your mortgage servicer adjust your escrow account to collect the increase. Homeowners who miss this detail can get surprised by a much larger tax bill than they expected.

Most programs allow prepayment without a penalty, which lets you clear the lien if you come into money or decide to sell. Confirm the prepayment terms with your specific program before signing.

Selling or Refinancing After PACE

Legally, a PACE assessment transfers with the property. In the actual mortgage market, that’s often not what happens. Fannie Mae and Freddie Mac, which back the majority of conventional mortgages in the United States, both have policies that effectively require the PACE lien to be paid off before they’ll purchase a loan secured by the property.

Fannie Mae will not purchase mortgages secured by properties carrying a PACE obligation with lien priority over the first mortgage, which in practice means almost all of them.⁸ Freddie Mac requires the PACE balance to be paid in full before it will back a refinance on a property with a senior PACE lien.⁹

The practical effect: a buyer using conventional financing will likely need the PACE balance paid off at closing, which usually comes out of your sale proceeds or your pocket. If you refinance, same situation. If you expect to sell or refinance within the term of the assessment, treat PACE as if it has to be paid off at that point rather than inherited by the next owner.

If You Fall Behind

Missed PACE payments are treated like missed property taxes, because they’re collected through the same system. Late amounts rack up the same penalties and interest your jurisdiction applies to delinquent taxes.

One meaningful protection: PACE debt does not accelerate on default. Missing a payment makes only the delinquent amount due, not the entire remaining balance, and future installments continue on schedule.¹⁰ A mortgage, by contrast, can be called in full after missed payments.

The flip side is the senior lien position. A prolonged delinquency can lead to a tax sale or tax foreclosure, which in some states runs through a non-judicial process that moves faster than a conventional mortgage foreclosure. The PACE lien survives that foreclosure, with any unpaid future balance transferring to whoever ends up with the property.¹⁰

Tax Treatment

The interest portion of PACE payments may qualify as deductible home mortgage interest, subject to the standard limits on mortgage interest deductions (currently $750,000 in total mortgage debt, or $375,000 for married-filing-separately filers). IRS Publication 936 sets out the rules.¹¹

Note the limit of that deduction: PACE payments are not deductible as property taxes. A special assessment that benefits a single property doesn’t count as a deductible real estate tax under federal law. Only the interest portion is potentially deductible, and only as mortgage interest. A preparer treating the full payment as a property tax deduction is handling it incorrectly.

Consumer Protections and the Pending Federal Rule

Residential PACE historically operated with weaker consumer protections than conventional mortgage lending. Because it was classified as a tax assessment rather than a consumer loan, federal Truth in Lending disclosures and ability-to-repay requirements didn’t apply. Programs in California and Florida drew particular attention from consumer advocates and state regulators over approvals for homeowners who couldn’t realistically afford the payments.

In December 2024, the Consumer Financial Protection Bureau finalized a rule that would bring residential PACE under Regulation Z, with an original effective date of March 1, 2026. The rule would require PACE creditors to deliver the same Loan Estimate and Closing Disclosure forms used in conventional mortgage closings, to make a good-faith determination that the borrower can repay the assessment based on verified income and debt information, and to provide PACE-specific disclosures warning that mortgage escrow payments will rise and that a future buyer’s lender may require the balance to be paid off.¹²⁵ Regulation Z’s three-business-day right of rescission on credit transactions secured by a home would also apply.¹³

As of early 2025, the CFPB suspended the effective date of this rule as part of a broader regulatory freeze. Whether and when it takes effect is unresolved. Until then, residential PACE borrowers in most states do not receive the disclosure and underwriting protections that apply to conventional mortgages. Check your state’s consumer protection agency for current status before signing.

Weighing PACE Against Alternatives

The structural appeal of PACE is real: no upfront cost, long terms, qualification driven by the property rather than your credit, and interest rates fixed for the life of the assessment. The structural cost is also real: the senior lien complicates any future sale or refinance, the interest rates are typically higher than conventional mortgage rates, and the fees roll into what you repay.

Before committing, run the numbers against what the improvement will actually save you. A solar system that cuts $150 a month off your utility bill but costs $200 a month in PACE payments only pencils out if you’ll hold the property long enough for the savings to catch up, and that calculation changes again if you’ll be forced to pay the balance in full at sale. If you have equity and reasonable credit, a home equity loan or cash-out refinance will usually come in at a lower rate and won’t create the lien-priority friction with Fannie Mae and Freddie Mac. PACE tends to make the most sense when those conventional options aren’t available or when a property owner specifically wants the debt tied to the real estate rather than carried personally.
