NYC's 2025 electrical code takes effect June 29. It adds mandatory plan review to every LL97 electrification permit.

On December 21, 2025, New York City adopted the 2020 National Electrical Code as the base for its updated electrical standards. Starting June 29, 2026, the DOB NOW filing system begins enforcing those standards on every incoming electrical permit application. For co-op and condo boards pursuing Local Law 97 compliance, the effective date is not administrative housekeeping. The categories of work that LL97 pushes buildings toward are exactly the categories the new code routes through mandatory plan review.

What the 2025 NYCEC replaced, and when the filing system catches up.

The 2025 New York City Electrical Code (NYCEC) supersedes the prior edition, which was based on the 2008 National Electrical Code. The 2020 NEC introduced updated requirements for arc-fault protection, ground-fault protection, energy storage systems, and EV charging infrastructure — categories that had grown faster than the prior code anticipated. The City Council adopted the 2020 NEC as NYC's base standard; the Mayor's Office approved the 2025 NYCEC, and the code took legal effect December 21, 2025, when the minimum DOB filing fee also rose from $100 to $130 under Local Law 128 of 2024.

The DOB's digital platform, DOB NOW: Build, had not yet been updated to reflect all of the new code's filing requirements. That gap closes June 29, 2026. Beginning that date, every electrical permit application filed through DOB NOW carries a new question set. The most consequential addition is a trigger field that identifies whether the scope of work includes any of a defined list of power-source categories. If it does, the filing is no longer self-certifiable; it must pass through mandatory plan review. Additionally, starting June 29, inspection requests for Electrical Development Inspections will be submitted through a new module (DOB NOW: Inspections Plus), replacing the prior DOB NOW: Inspections workflow. Contractors and expediters using the old module will need to route through the new one from that date forward.

The trigger list — and why it maps onto LL97 compliance work.

The new DOB NOW question asks whether the electrical filing covers installation of service equipment, transformers, UPS systems, generators, generator paralleling equipment, energy storage systems, fuel cells, photovoltaic systems, DC or AC microgrids, cogeneration plants, or stationary batteries.

That list is not incidental. It is the equipment inventory of LL97 compliance. Local Law 97 (Int 1253-A of 2019) capped carbon emissions from NYC buildings over 25,000 square feet, with penalties of $268 per metric ton over the limit beginning in 2024 and tighter caps in 2030. The primary technical paths boards and engineers have pursued to hit those caps are solar photovoltaic installations, battery energy storage systems (to shift load away from carbon-intensive grid power), on-site generators (for backup resilience as the building's boiler plant is decommissioned), and electrical service upgrades to support heat pump conversion. Every one of those paths now requires that the filing include a fully approved plan set before DOB will process the permit.

The distinction the new rules draw is between an "Approved" letter and an "Approval with Conditions" letter. Under the prior system, a project could proceed with an engineering drawing still in review, receiving an approval-with-conditions letter as a placeholder while outstanding items were resolved. Beginning June 29, that path is closed for the trigger categories above. The permit application will not move forward until a letter explicitly stating "Approved" has been uploaded. For buildings that have not yet retained a licensed professional engineer for the design review, that step is now a prerequisite to permit submission, not something that can run in parallel.

The fee cap that was removed.

New York City's electrical permit fee schedule is codified in 1 RCNY §101-03. Among the components of that fee is a Parts Fee, which scales with the number of outlets, circuit breakers, fixtures, and individual components in the permitted scope. Under the prior fee structure, the Parts Fee was capped at $5,000 per filing, regardless of project scale.

That cap has been removed as of June 29, 2026. The NYC DOB service update states directly: "The maximum Parts Fee of $5,000 is no longer in effect." [Primary source: NYC DOB Service Updates]

For a co-op or condo board running a building-scale installation (a 200kW solar array, a battery storage system sized for whole-building backup, or buildingwide EV charging across a parking structure with 150 spaces): the parts count runs into the hundreds or thousands of individual circuit components. Under the old cap, the board's Parts Fee exposure was bounded at $5,000. Under the new structure, the fee scales with the job. The base filing fee is also now $130 (up from $100), and each permit renewal requires a separate $130 fee. [Primary source: NYC Admin Code §28-112.2; Local Law 128 of 2024]

Permit duration and the LL97 timeline problem.

Electrical permits issued under the new rules are valid for a maximum of 12 months, after which the permit must be renewed. The renewal fee is $130. LL97 electrification projects at large NYC residential buildings commonly run beyond 12 months from permit application to final inspection sign-off. A solar installation on a 200-unit co-op in a dense Manhattan neighborhood can take several months for engineering and design, additional months for DOB plan review, and six or more months for physical installation, fire-safety coordination, and inspection. A building that submits a permit in July 2026 may reach permit expiration before the certificate of completion is filed.

The permit duration rule layers onto a timeline that is already stretched. The C-PACE financing gap documented on this site (Local Law 97's C-PACE financing tool has a structural gap for co-ops) showed how the first NYC co-op to close a C-PACE deal spent nine months obtaining written lender consent from its blanket mortgage holder. The NYCEC plan review requirement is a distinct friction point, earlier in the same compliance pipeline: before the money is even deployed, the permit queue has grown longer and more expensive.

One additional operational item boards should know: as of June 29, DOB NOW blocks new electrical filings on any property with an open work-without-permit (WOP) violation on the building's BIN, regardless of whether the WOP relates to electrical work or to some other prior project. A building with an outstanding WOP from a prior renovation that was never properly closed out cannot submit a new electrical filing until that violation is resolved. The NYC Buildings portal (nyc.gov/site/buildings) supports a BIN-based violation search. Boards should run that check before assuming a new permit application will clear.

What boards should do before June 29.

If your co-op or condo board has authorized an LL97 electrification project and engineering work is in progress, the most direct question to ask the engineer is whether the permit application can be filed before June 29. A filing submitted before that date is subject to existing requirements; the new plan review trigger, uncapped Parts Fee, and Inspections Plus module apply to filings submitted on or after June 29.

If the project is not yet far enough along for permit submission, the board should budget for the new requirements explicitly. Plan review by a licensed professional engineer adds both cost and time before the DOB will accept the filing. The Parts Fee will scale with the project, not be capped at $5,000. The permit clock starts at filing, runs for 12 months, and requires a renewal filing (and fee) if the job extends beyond that. And payment method matters: eCheck payments take 10 or more business days to process after submission, during which the filing remains in "Pending Payment Verification" and no inspection can be requested. Credit card payments process immediately.

Finally, check for open WOP violations on the building's BIN. The check takes five minutes. An unresolved WOP that nobody remembers will block a new electrical filing entirely.

Bottom line.

June 29 is not a new requirement to do anything. Buildings are not required to install solar panels or battery storage. But for the co-op and condo boards that have already committed to those projects to meet LL97's carbon limits, the compliance path through DOB just added cost and time at every step: mandatory plan review before permit submission, no cap on parts fees, 12-month permit expiration, and a new inspection-request workflow. The local-law extraction stack adds a layer not via a new mandate but via updated procedures on the existing ones. The cost is structural, not accidental.
