Compliance. For years, selling electricity by the kilowatt-hour lived in a regulatory gap, and the industry's habit was to call the rules "emerging." They have emerged. NIST Handbook 44◆ Section 3.40, Electric Vehicle Fueling Systems, became permanent code on January 1, 2023, and most states adopted it effective January 1, 2025. Charging by the kWh is now weights-and-measures commerce, the same legal category as the gas pump, inspected by the same county office that checks gas pumps and deli scales.
The requirements are specific. New DC equipment has been held to a 1.0% acceptance and 2.0% maintenance accuracy tolerance since January 1, 2025. Units must display energy delivered, unit price, and total price; receipts must carry quantity, unit price, total, capacity, and the EVSE identifier. The legacy allowances are generous but they end on dates certain:
| Requirement | Applies to | Effective | Status |
|---|---|---|---|
| HB 44 §3.40 permanent code | All kWh-billed EVSE | Jan 1, 2023 | In force |
| State adoption (most states) | All kWh-billed EVSE | Jan 1, 2025 | In force |
| 1.0% / 2.0% accuracy tolerance | New DC equipment | Jan 1, 2025 | In force |
| Display exemption expires | DC units | Jan 1, 2028 | Ahead |
| Class 5 (5.0%) legacy allowance expires | Legacy DC units | Jan 1, 2034 | Ahead |
For procurement, the operative distinction is certified versus compliant◆. CTEP◆ and NTEP◆ certification is a credential issued after testing; "compliant" is a promise a sales deck makes. Require the certificate, ask which jurisdictions it covers, and remember that equipment can be perfectly legal to install and simultaneously illegal to bill with, a distinction owners discover at inspection, which is the expensive place to learn it.
MARGIN NOTE Accessibility is its own requirement set, not an inheritance. An EV charging stall does not become accessible because the parking stall it occupies was; accessible charging carries its own dimensional, route, and operable-parts requirements, and retrofitting them after installation routinely costs more than the charger. Design them in at the make-ready stage (section 7.11).
Mandates and the Right-Sizing Argument. EV-Capable◆ requirements are cheap insurance; EV-Installed◆ mandates are expensive guesses. Codes should require conduit and panel capacity, the bottom rung of section 7.11's ladder, bought at construction for a fraction of its retrofit price, and let demand set the installation schedule. That single sentence is the Council's position, and the rest of this section is why it should be the code's.
The parking industry has run this experiment before. Minimum parking requirements mandated capacity ahead of demand for seventy years, and the result (stranded capital, distorted development, land converted to obligation) became the case that reform advocates, this Council among them, carried successfully in Buffalo, Hartford, San Jose, and Austin. An EV-Installed mandate repeats the structure of that mistake with more expensive equipment: it fixes today's guess about 2035 demand in today's hardware, which will be obsolete on the day the demand arrives. Conduit does not obsolesce. Capacity does not strand. The mandate that requires readiness and defers installation captures the entire cost advantage of building early while leaving every equipment decision to the moment, and the registration data of section 7.9, that can actually inform it.
For the owner in a mandate jurisdiction, the practical reading: an installed-charger requirement is a compliance cost to be right-sized ruthlessly (minimum compliant count, Level 2 unless dwell argues otherwise, ALMS from the first port), while the capable-stall requirement is the code doing the owner a favor at the cheapest possible moment. Advocacy belongs upstream of both: the Council's model language, and the full policy argument for elected officials, is maintained in the Right-Sizing brief in PCC Research.
MARGIN NOTE The chapter closes where it opened: capacity, not equipment, is the durable asset. Section 7.1 made the structure last; section 7.17 asks the code to let demand -- not mandate, not headline -- decide what plugs into it.
For the Council: Reviewing This Draft
This is the first complete chapter of The PCC Book of Parking, presented as the template for the sixteen that will not be written this way -- seven briefer, some longer, all carrying the same voice and apparatus. Three review questions matter more than line edits at this stage:
- The voice: declarative, plain-spoken, written to be cited. Is this how the Council wants to sound for the next decade?
- The apparatus: revision records, glossary links, margin notes, case studies, and "Where the Evidence Ends" panels. Does the machinery earn its space on the page?
- The claims: each section leads with one. Where a Domain Editor would state a claim differently, that disagreement is exactly the peer review the living edition runs on.
Technical review is specifically invited on the verified figures (7.9, 7.12, 7.16), the dwell-time table (7.10), and the Council position stated in 7.17. Sections 7.6 and 7.13 carry "Where the Evidence Ends" panels and will tighten as standards converge and operator data accumulates. That is the living edition working as designed, in public, with its dates showing.
A note on the figures. Eight print-quality figures accompany this draft; each caption states plainly whether its values are verified or illustrative, in keeping with the chapter's confidence-labeling discipline. In the online edition, each becomes an interactive chart: the right-speeding curve responsive to the reader's own dwell input, the demand panel updating as registration data refreshes, built on the same visualization framework as the Council's white paper series.

Adaptive Reuse and the Future-Flexible Structure. Design decisions made today (flat floors, taller floor-to-floor heights, perimeter ramps, loading capacity beyond the parking minimum) determine whether a garage built in 2026 can become housing, logistics, or fleet staging in 2046. A conventional garage with sloped floors and seven-foot clearances can become exactly one thing: a conventional garage. The future-flexible structure keeps its options, and options on urban land have a way of appreciating.
Be honest about the premium. Flat-plate construction with speed ramps, residential-grade floor-to-floor heights, and upsized utility rough-ins cost real money at initial construction, and the Book will not pretend otherwise. The honest frame is option value: the owner is buying the right, not the obligation, to convert, and the price of that right at construction is a fraction of its price as a retrofit, where it is frequently unbuyable at any price. Whether the option is worth its premium is a site-by-site underwriting question: land value trajectory, zoning flexibility, and the horizon of the parking demand itself.
What makes the question urgent rather than academic is the transition this Book gives its own chapter. Autonomous fleets, staging demand, and the evolve-ready◆ asset are Chapter 8's territory; the design vocabulary that keeps a 2026 structure relevant to that future is decided here, in this section, before the concrete sets.
track the mandate map and the metrology deadlines as compliance items with dates, and answer both with the future-flexible asset: make-ready capacity banked, loads planned, and a structure that can carry the next requirement without a redesign.
