If you own or develop property, the headlines about "paused EV mandates" can read like a signal to stop planning charging. They are not, because two very different kinds of rule share the word "mandate," and only one of them is in trouble.
Two rules that get confused
A vehicle-sales mandate tells automakers what share of new cars they must sell as zero-emission. California's Advanced Clean Cars II (ACC II) is the best known, with a ramp that starts at 35 percent of each manufacturer's new California vehicle sales in model year 2026 (a share that can include plug-in hybrids) and reaches 100 percent by 2035. Other states adopted it by reference. It regulates manufacturers and dealers. It puts no obligation on your parking lot.
A building-code EV requirement tells a developer how much of a new or heavily renovated parking facility must be EV-capable, EV-ready, or fitted with chargers. It is enforced at the building department, at permit and inspection. Our state EV charging mandates article walks through the tiers and the states that have them.
Everything below is about the first kind. The second kind has not been touched by the actions described here.
What has actually happened to the sales mandate
The legal footing has been shaky for well over a year.
- June 2025: Congress used the Congressional Review Act to disapprove three California waivers, including the one that let the state enforce ACC II, and the President signed the resolutions on June 12, 2025. California and a coalition of states sued the same day; that case, California v. United States, is still pending in federal court in California.
- March 12, 2026: The Justice Department, with the Department of Transportation involved, sued the California Air Resources Board (CARB) in the Eastern District of California. According to press reports of the complaint, it argues that the state's light-duty CO2 standards and EV targets are preempted by federal fuel-economy law and asks for a permanent injunction. We found no ruling in either case as of this writing, but we did not check the dockets directly.
- March 26, 2026: CARB approved permanent adoption of its fallback vehicle emissions regulations, which let automakers meet older state standards while the litigation continues, and said manufacturers can also comply with ACC II voluntarily.
- State pullbacks: Vermont's governor paused enforcement of ACC II, Advanced Clean Trucks, and the heavy-duty Omnibus rule by Executive Order 04-25 on May 13, 2025, citing charging availability and affordability. Maryland says it will not pursue penalties for model year 2027 and 2028 shortfalls unless voluntary agreements cover at least 40 percent of its market (as our state mandates article describes it), and Massachusetts is not enforcing its model year 2026 and 2027 sales requirements against automakers that meet the conditions in MassDEP's May 23, 2025 notice. We did not find a current enforcement status for every state that adopted the rule, so check your state's environmental agency before relying on any of this.
Put plainly: the sales mandate is legally contested, unevenly enforced, and may not survive in its current form. A reasonable reader could conclude it is not a dependable planning input. That is exactly the point.
Why the building decision does not hinge on it
Your charging project has three real inputs, and a sales mandate is none of them.
- Your code. If your jurisdiction requires EV-capable or EV-ready spaces in new construction, that obligation comes from the building or energy code, adopted separately from any vehicle rule. California's 2025 code edition took effect January 1, 2026, and Colorado, Washington, and New Jersey each have their own schedules, laid out in the state mandates article. Whether a vehicle-sales rule is paused changes none of those permit requirements.
- Your drivers. Charging pays when the people who park at your property need it and stay long enough to use it. Tenants, employees, guests, and fleet vehicles are the demand. They arrive in the cars they already own and the ones they buy next, regardless of what a regulator requires dealers to stock. Our signals your property is ready piece lists what to look at.
- Your economics. Utility rates, incentives, and install cost decide whether a project clears your hurdle. The ROI snapshot is where that gets tested.
What a paused mandate can legitimately change is the pace of market growth in some states. If you were counting on a forced ramp in vehicle supply to fill your chargers on a schedule, that assumption is now weaker, and your model should not lean on it. For many properties that argues for the conservative path: conduit and panel capacity now, chargers when your own demand shows up. Our piece on when charging does not make sense covers the wait-versus-never distinction.
What to do with this
- Check whether your jurisdiction's building code carries an EV requirement for your project type, and treat that as fixed regardless of the vehicle-rule news.
- Strip any vehicle-sales-mandate assumption out of your demand forecast; base it on observed drivers at your site.
- If you build new, price the cheap options (raceway and panel headroom) now, because the expensive moment is always the retrofit.
- Revisit the question when the courts rule. Both federal lawsuits over the light-duty rule are open, and either outcome mostly moves vehicle supply, not your code.

Direct page fetches of justice.gov, oag.ca.gov, dec.vermont.gov, and carb.ca.gov were not possible from our research environment, so those items were confirmed from search-result excerpts of the primary documents and at least one independent report each; the Maryland and Massachusetts terms were carried from our state mandates article, verified October 3, 2026, and not re-fetched. We did not confirm current enforcement status for Colorado, Oregon, Washington, or New Mexico. This is general information, not legal advice.
