Quick answer

Solar panels need a Town of Brookhaven building permit, and 'Solar Panels' is one of the residential permit types the town lists for its online application. The Building Division also requires a notarized Solar Permit Affidavit in which the owner attests that every structure on the property, including the one the panels go on, holds a valid certificate of occupancy or equivalent, and states whether there is a pool on the property and whether it has a certificate of compliance. Zoning Sec. 85-13.B sets up a solar energy fast-track permit for residential roof-mounted work that meets a list of conditions, with a Solar Energy Fast Track Permit Application Requirements Checklist and three sets of plans.

How to apply in Town of Brookhaven

A rooftop solar PV permit application is a combined structural and electrical plan set: a site plan and roof framing details proving the array's mounting can carry its added loads, plus a one line electrical diagram covering listed modules and inverters, disconnects, and the rapid shutdown design. Utility interconnection is a separate approval that runs in parallel with the permit.

What most solar permit applications include:

  • Both a building permit and a separate electrical permit are required, since the array must be designed and installed to the residential code's solar provisions and to the National Electrical Code (IRC R324.3).
  • The plan set identifies listed equipment: PV modules listed to UL 1703 (or both UL 61730-1 and UL 61730-2), and inverters listed to UL 1741, with grid-tied inverters listed for utility interaction (IRC R324.3.1).
  • Structural drawings show that the roof framing is designed to structurally support the array and withstand the gravity loads it adds (IRC R324.4.1).
  • The site plan lays out roof access pathways at least 36 inches wide, plus a ridge setback sized to how much of the roof the array covers, so firefighters retain pathways and ventilation access (IRC R324.6.1, IRC R324.6.2).
  • The one line electrical diagram shows the rapid shutdown method and the location of its single initiation device, since one control point must bring all system conductors down to safe levels (NEC 690.12, NEC 690.56(C)).
  • Interconnecting the array to the utility grid at a defined point of connection is a separate application process from the local building or electrical permit and must be approved before the system can operate (NEC 705.12).
  • Some permitting offices route applications through SolarAPP+, an automated review platform that checks the plan set against code requirements and issues eligible permits instantly (DOE SolarAPP+).

Inspections and closing out your permit

Inspectors verify the installed array against the approved plans, and some agencies run a rough check of roof attachments and penetrations while they are still exposed before the wiring and roofing close them in. The final inspection confirms rapid shutdown, disconnects, grounding, and required labels are installed correctly, and the system cannot be energized until the utility separately approves interconnection.

  1. Where an agency runs a rough or pre-inspection, it checks the array's roof penetrations while they are still exposed, confirming they are flashed and sealed (IRC R324.4.3).
  2. The inspector confirms whether rapid shutdown is required, how it is accomplished, and that it is properly identified (NEC 690.12, NEC 690.56(C)).
  3. PV disconnecting means must be permanently marked and installed where they are readily accessible, which the inspector confirms in the field (NEC 690.13).
  4. Bonding and grounding of the array, including every exposed non current carrying metal part and the grounding electrode system, is checked before sign off (NEC 690.43, NEC 690.47).
  5. At the service equipment, the inspector looks for the required rapid shutdown placard, a labeled diagram showing the initiation device's location in the specified colors and letter sizes (NEC 690.56(C)).
  6. Utility interconnection is inspected and approved separately from the local building department's sign off, and the system cannot be energized until both approvals are in hand (NEC 705.12).

Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Town of Brookhaven permit portal or by phone at 631-451-6333.

Can a homeowner pull a solar permit themselves in Town of Brookhaven?
Under New York law (Inside New York City: NYC Admin. Code 28-104.1, 28-105.1, 28-105.4, 28-105.5.1, 28-401.3 (definition of "general contractor"). Outside New York City: N.Y. Exec. Law 381(2); 19 NYCRR 1203.3(a)(1).): New York State sets no owner-builder rule at all outside New York City. Executive Law 381(2) puts administration and enforcement in the hands of each local government, and 19 NYCRR 1203.3(a)(1) only requires each authority having jurisdiction to make building permits mandatory for work that must conform to the codes, leaving who may apply to local law. The state licenses no general contractors and imposes no owner-builder affidavit, disclosure form or post-permit sale restriction of the kind Florida uses, so whether a homeowner may pull the permit is a question for the specific city, town, village or county. New York City is the genuine outlier. Administrative Code 28-105.1 makes the work itself unlawful without a written permit, and Administrative Code 28-104.1 bars the department from issuing that permit until it approves the required construction documents, which must be prepared by or under the supervision of a registered design professional, meaning a licensed architect or engineer, as required by the code. A homeowner therefore cannot self-prepare and file the plans for permit-requiring work in New York City even though Administrative Code 28-105.5.1 defines the permit applicant as the person who performs the work or retains a subcontractor, and even though the general contractor registration definition in Administrative Code 28-401.3 expressly excludes an individual who constructs a residential structure of no more than three dwelling units for his or her own occupancy. Note that Administrative Code 28-105.4 exempts minor alterations and ordinary repairs from the permit requirement entirely, so the design professional bottleneck applies only to work that needs a permit in the first place. Confirm how Town of Brookhaven applies this before you apply.
