Nothing Changed, and Everything Did: What Sheetz v. El Dorado Really Means for Impact Fees

If you work in municipal finance, planning, or public works, you have probably heard the name "Sheetz" mentioned in the same breath as "impact fees" over the past two years. It is worth understanding this case well, because it is the most important thing to happen to development impact fee law in a generation, and it is still not fully resolved.

Here is the story in plain terms, why it matters, and why it makes a properly documented nexus study more important than ever.

How it started: a $23,420 permit fee

In 2016, George Sheetz, a retiree in rural El Dorado County, California, applied for a permit to build a small manufactured home on a 10-acre lot. Before the county would issue the permit, it required him to pay a Traffic Impact Mitigation (TIM) fee of $23,420, money meant to help fund road improvements across the county.

Sheetz paid the fee under protest and sued. His argument was simple: the county never showed that his one small house actually caused $23,420 worth of traffic impact. He said the fee was calculated by a general schedule, not tied to his specific project, and that this violated his constitutional rights.

California courts had a long-standing rule that made this kind of challenge very hard to win. Under a legal doctrine going back decades, if a city or county adopted a fee through legislation, such as an ordinance or a fee schedule approved by the council or board, that fee was not subject to the same tough scrutiny as a fee imposed one-on-one by a planner or building official. The trial court and the California Court of Appeal both ruled against Sheetz on exactly this basis. The California Supreme Court declined to take the case.

Round one at the U.S. Supreme Court: a unanimous win

Sheetz did not stop there. His attorneys at Pacific Legal Foundation took the case all the way to the U.S. Supreme Court, and in April 2024, the Court ruled unanimously in his favor.

The Court's reasoning was straightforward: the Constitution does not care whether a government took your property (or your money) through a legislative act or an administrative decision. Either way, if a permit condition amounts to an exaction of money or property, it has to satisfy the same two-part test that has applied to individual permit conditions since the 1980s and 1990s, known as the Nollan/Dolan test:

• Essential nexus: Is there a real connection between the fee and the impact the government is trying to address?

• Rough proportionality: Is the amount of the fee roughly proportional to that particular impact?

  
  

This was a big deal. It meant that California's rule exempting legislatively adopted fee schedules from this scrutiny was unconstitutional. Cities and counties across the state that had been relying on that exemption suddenly had to assume their fee programs could be challenged under the same standard used for individual, discretionary permit conditions.

However, the Supreme Court did not decide the whole case. It sent the matter back down to the California courts to actually apply the Nollan/Dolan test to Sheetz's fee and figure out how "rough proportionality" should work when a fee is charged to an entire class of properties rather than negotiated one at a time.

Round two: the Court of Appeal upholds the fee anyway

In July 2025, the California Court of Appeal ruled on remand. This time it applied the Nollan/Dolan test as instructed, and it upheld the county's fee again.

The court found the essential nexus test was easy to satisfy: a new home generates more car trips, and the county's traffic mitigation program exists to address the impact of new development on the road network. That connection was enough.

On rough proportionality, the court put the burden on Sheetz to prove the fee was not reasonably related to his project's impact, and found he had not done so. The county's fee methodology, built on traffic studies, growth projections, geographic zones, and class-based estimates of trip generation, was treated as sufficient. In practice, this meant the court reviewed whether the county's methodology was sound and well-documented, rather than second-guessing the dollar amount charged to Sheetz individually.

For a moment, this looked like the clarifying, practical roadmap that cities and consultants had been waiting for since 2024: build your fee program on solid data, and it can survive the Nollan/Dolan test even after Sheetz.

The twist: depublication

Sheetz asked the California Supreme Court to review that 2025 decision. The California Supreme Court denied review, but on its own initiative it also ordered the Court of Appeal's opinion depublished.

Depublication is a distinctly California procedural tool. It means the ruling still applies to the parties in that specific case, but it can no longer be cited as precedent by anyone else, in any other case, going forward. For all practical legal purposes, it is as if the opinion does not exist.

Sheetz's own attorney summed up the frustration well: the depublication order meant the decision could not be cited and did not constitute law, even though it had just spent months walking through exactly how a post-Sheetz fee analysis should work.

Round three: back to the Supreme Court, and the door closes

Sheetz was not done. In February 2026, he filed a second petition asking the U.S. Supreme Court to hear his case again, a rare move so soon after already winning there once. His argument was that the depublished decision had effectively revived the same flawed logic the Supreme Court had already rejected in 2024, just dressed up as deference to methodology instead of an outright legislative exemption.

The petition drew amicus support from several building industry and property rights organizations. The case was distributed for the Court's June 11, 2026 conference, and on June 15, 2026, the Court's docket recorded a simple two-word outcome: petition denied. It takes only four justices to agree to hear a case, and Sheetz did not get them.

That denial ends George Sheetz's decade-long individual fight. But it does not resolve the underlying legal question. Because the one appellate decision that actually worked through how rough proportionality applies to a broad, class-based fee schedule has been depublished, there is currently no binding California appellate precedent on that exact question. The issue is unsettled, and further litigation on this point is widely expected.

Why this matters for every city's fee program

Here is the headline for anyone who adopts or relies on development impact fees:

The days of "our fee schedule was adopted by ordinance, so it is automatically safe" are over. Since Sheetz, every legislatively adopted impact fee, DIF, or exaction is potentially subject to the same constitutional scrutiny as an individual, discretionary permit condition. A city cannot simply point to the fact that its council adopted a fee schedule as a shield against a takings challenge.

At the same time, the depublication of the Court of Appeal's 2025 decision means there is no settled, citable California case law telling agencies exactly how to satisfy rough proportionality for a broad fee program. Agencies are, in effect, back to first principles: build a record that can independently withstand scrutiny, because there is no binding shortcut anymore.

Why a properly documented nexus study is the answer

This is exactly the gap a well-built nexus study is designed to fill, and it is why the quality of that underlying analysis matters more now than it did before 2024.

A defensible nexus study needs to do more than produce a number. It needs to build and preserve the record that demonstrates:

• Essential nexus: a clear, documented, logical connection between the fee and a specific, legitimate public impact caused by new development, such as additional trips generated, added demand for parks acreage, or increased service calls.

• Rough proportionality: a methodology, grounded in real data such as traffic studies, current facility inventories, adopted level-of-service standards, and growth projections, that ties the fee amount for each land use category to that category's actual, quantifiable share of the impact.

• A clean, defensible paper trail: consistent categories, correct fund balances, accurate unit costs, and no unexplained gaps between the study's assumptions and the fee ultimately adopted by the governing body.

  
  

Before Sheetz, an agency could lean on the fact that its fee was adopted legislatively. That cushion is gone. Now, if a fee is challenged, the agency's only real protection is the substance of the nexus study itself: can it show, with real data and sound methodology, that the fee is fairly and proportionally connected to the impact of the development being charged.

In other words, the legal question has shifted from "who adopted this fee" to "can you prove this fee is fair." That is precisely the question a rigorous DIF nexus study is built to answer, and precisely why cutting corners on that analysis is now a much bigger liability than it used to be.

The bottom line

Sheetz v. County of El Dorado closed with a whimper rather than a bang. The property owner ultimately lost on the merits, and his case is over. But the legal landscape it leaves behind is anything but settled. Every impact fee program in California, and arguably in every state, now lives under a standard that requires real, defensible proof of nexus and proportionality, without a clear, citable roadmap for exactly how much documentation is enough.

For agencies, the lesson is simple: this is not the year to treat a nexus study as a formality. It is the document that stands between your fee program and a Sheetz-style challenge, and after this ruling, it is doing more legal work than it ever has before.
