A Buffalo NY solar permit is two city filings and a National Grid application, not one PDF titled “solar.” Crews that treat Buffalo like a USP village upload a single electrical sheet, then sit in ePermits while Repair is missing, or they pull both city permits and file a Con Edison SLD with the wrong utility. DPIS and National Grid will each bounce what is not theirs. They will also bounce what disagrees.
Athol Energy prepares New York solar design and permit design for production installers, including Buffalo and the inner-ring towns. We are not a homeowner sales office. The drawings have to show a Western New York roof that will hold snow, an electrical service a National Grid tech will recognize, and sheet titles a DPIS clerk can assign to Repair versus Electrical.
What Buffalo NY solar permit drawings must show DPIS
ePermits is explicit that solar needs a Repair permit and an Electrical permit. Repair is the mounting and building work: racking, attachments, roof penetrations, snow guards if you are adding them, and any structural sistering. Electrical is the PV circuits, inverter, disconnects, grounding, and the interconnection at the service. If your “plan set” is only an SLD, Repair has nothing to review. If your set is only a roof layout, Electrical has nothing to review. Issue both, with a shared equipment schedule.
The Department of Permit and Inspection Services is the AHJ. Address used on city pages is 65 Niagara Square, Room 301. Upload through ePermits rather than emailing a Dropbox link and hoping. Mechanical, electrical, and plumbing each want their own permit when those trades are in play. Solar is called out as a two-permit case so nobody “forgets” Repair the way they forget plumbing on a heat pump. Do not make the clerk infer the structural scope from a note on sheet E-001.
Roof plans for Buffalo have to take snow seriously. This is not a Long Island edge-zone conversation and it is not FDNY 6-foot paths. It is drift against a parapet, a low-slope TPO with ballast questions, or a 1920s rafter roof with a new tub in the attic. Show rafter or truss size and spacing if you have it. If you do not have it, say so and get photos from the hatch before a PE is asked to invent 2x6s. Attachment layout needs dimensions a tape can hit: edge distances, row spacing, and the distance to the ridge and eaves the inspector will walk. Missing dimensions are a QA fail on our desk because they are a field fail on yours.
Electrical sheets need conductor and conduit notes, not a pictogram. Rapid shutdown and placard notes should match the code edition DPIS is enforcing. [CONFIRM AS OF 2026-09-19: NEC edition Buffalo currently cites.] Show the existing main size, the proposed interconnection method (load-side breaker versus supply-side tap), inverter model, and AC kW. If the panel is a split-bus or a Stab-Lock, NY-Sun will not accept the tap and the electrical inspector should not either. Put the panel replacement on the Repair/Electrical scope before the truck rolls.
National Grid NY is the third permit you cannot skip
Interconnection in Buffalo is SIR through National Grid’s IOAP. The SIR effective February 9, 2026 still splits 50 kW and below from the large process, with no application fee at or below 50 kW. Appendix F wants a PV single-line with component ratings and protection settings, site plan information, UL 1741 documentation, and account/meter numbers on existing services. National Grid CESIR packages want a PE-stamped single-line. A 8 kW residential job should not get a primary-voltage CESIR title block, and a 2 MW warehouse should not get a cartoon house SLD.
Match the National Grid diagram to the Electrical permit sheet: same inverter, same kW, same PCC, same disconnect location. If National Grid wants a three-line because the service is three-phase, produce it for the portal and keep a simpler one-line for DPIS if that is what the electrical examiner reads. Title the three-line so it is not mistaken for a construction change to the Repair set.
PTO is National Grid’s letter after inspection and their process. A DPIS final on Repair and Electrical does not energize the array. Sequence the electrical inspector, the city finals, and the National Grid closeout. If the field moved the disconnect, as-built drawings have to hit both DPIS (if they want a revision) and National Grid before you argue with the meter department.
Towns next door are not Buffalo
Amherst, Cheektowaga, Tonawanda, and Hamburg are separate AHJs. Some appear on NYSERDA’s USP adopter lists. Buffalo’s ePermits language does not. If your crew works the metro as one “Buffalo” sales region, your permit desk cannot. Confirm USP, fee, and PE expectations with that town. Snow load still applies. National Grid still applies for most of the county. The cover sheet changes.
Lake-effect snow and older housing stock are why we see structural comments even on modest arrays. If the attic shows undersized rafters, cracked plaster, or a prior leak under the proposed array, stop and get a PE look. PE stamping is not automatic on every Buffalo residential job, and it is not optional once DPIS or the engineer of record says the roof is in question. Wet versus digital follows what DPIS will accept. Ask before the seal is applied in a format the portal rejects.
NY-Sun and the Buffalo photo set
If NY-Sun is in the bid, the April 2026 Program Manual still wants site photos from ground and roof, looking south, plus service and inverter location. A single Google aerial does not count. Tree removal on the East Side or in a wooded North Buffalo lot has to appear on the NY-Sun site map. The DPIS roof plan can show the same trees if they affect access or drift. Do not tell NYSERDA the maple comes down and tell DPIS the array is already clear.
Cut sheets for modules, inverters, and racking belong in both city uploads if the portal allows attachments, and they must match the schedule. Incomplete cut sheets are a common resubmittal. Conflicting callouts (200 A main on the site plan, 150 A on the SLD) are the other. QA here is aimed at those, not at making the cover pretty.
Comments we see after the first ePermits upload
Repair reviewers ask for flashing details and whether the array sits on a reroof. If the shingles are at end of life, say so on the roof plan. An inspector who sees new penetrations in failed shingles will fail the job even if the SLD is perfect. Electrical reviewers ask for working clearances at the inverter, the disconnect height, and whether the service equipment is in a garage that floods. Buffalo’s older stock includes knob-and-tube remnants and panels that NY-Sun already banned as interconnection points. Photograph the panel directory. If the directory is fiction, the load-side breaker you drew may not exist.
Snow guards and drift against a neighboring parapet are winter comments. If the array sits low on a shared wall, show the gap. If you are using ballast on a low-slope membrane, the Repair set needs the ballast plan and roof warranty note, not only a typical rail. Ballast that migrates in lake-effect wind is a callback, not a paper comment.
Row houses and two-family buildings need a site plan that shows which unit owns the roof and which meter is interconnecting. National Grid will not PTO an array on the wrong account. DPIS will not sort a family argument. Put the unit letter on the cover.
Commercial Buffalo jobs (warehouses along the beltway, school roofs) need a three-phase story and often a PE. Fire access on a big roof is still a path, even without FDNY. Draw equipment pads, skylights, and HVAC before you fill the remaining square footage with modules. If National Grid later wants a recloser, keep that off the Repair set until it is customer-owned.
Intake that keeps Repair and Electrical in the same week
Send address, whether it is City of Buffalo or a suburb, roof photos including the attic if you have them, service photos, equipment list, National Grid account, and the install week. Incomplete intakes get a checklist. We will label sheets for Repair versus Electrical, keep the National Grid SLD honest, and tell you if a PE letter is likely before you promise a date.
Buffalo is straightforward compared with DOB NOW. It is not a verbal approval. File Repair, file Electrical, file National Grid, and keep the module count still. A Buffalo NY solar permit package that does that will get a crew on a roof instead of a clerk’s deficiency list. Phone +1 (209) 266-2669 with the DPIS job address and the utility account.
