A Greenwich CT solar permit stalls when the site plan is a covenant collage: HOA color notes, HDC narratives, and ARC screening, with no dimension to the property line the building official needs. Greenwich is an in-person building-permit town for work that is not a simple reroof. Historic lots add HDC. Some commercial and multifamily lots add Architectural Review Committee mechanicals. HOA boards add a fourth audience. If you mix those audiences on one unlabeled sheet, every reviewer finds a reason to bounce you.
Athol Energy drafts a clean permit design set for the building official, then adds labeled extras for HDC, ARC, and HOA. We do not let an HOA committee caption become the electrical one-line. Residential Greenwich jobs still get site plan, roof plan, attachment dimensions, one-line, cut sheets, and placards.
Greenwich CT solar permit site plan layers that belong (and do not)
AHJ layer: property lines, building footprint, roof outline, array extent, equipment pads, trench or conduit routes, disconnect and meter, north arrow, scale, and height if anything is ground-mounted. If Planning and Zoning site-plan approval is required under Building Zone Regulations Section 6-13, that is a P&Z clock, not a PE clock. Confirm whether your occupancy and zone trip Section 6-13 before you tell a homeowner it is “just a building permit.” [CONFIRM AS OF 2026-09-19]
Building permit layer: CT Standardized Solar PV Permit Application Supplement, one-line, attachment details, cut sheets, structural evaluation if Greenwich requires it. File in person per the town’s process page, which limits email filings to reroof, reside, and replacement windows on 1-2 family dwellings. Do not email a PV set and hope. Follow-up documents for pending permits can go to [email protected] per that page, with a warning that unprintable files will be sent back for hard copy.
HOA layer: module color, rail finish, inverter location, screening, and any covenant setback that is stricter than zoning. Put it on an HOA exhibit with the covenant excerpt. Do not rewrite the electrical one-line to “black modules only” as a UL note. If the HOA demands a layout that eats fire pathways or overloads a rafter bay, we say no on the drawing and send the owner back to the board. We will not stamp an unsafe HOA sketch.
HDC layer: Certificate of Appropriateness for mapped historic districts and local historic properties. Connecticut General Statutes § 7-147f says the commission shall not deny a certificate for a solar energy system designed to use renewable resources unless it finds the feature cannot be installed without substantially impairing the historic character and appearance of the district. The certificate may include stipulations on design modifications and location that do not significantly impair effectiveness. That is your legal frame. It is not a blank check for a street-facing gable. Draw concealment first. HDC meetings are listed on the town HDC page (second Wednesday, no August meeting in the calendar we reviewed). Packet deadlines are two weeks before the meeting per that page. Confirm live. [CONFIRM AS OF 2026-09-19]
Historic Overlay lots use P&Z Division 9 Sec. 6-109. Mandatory review of changes to historic assets can apply. Map HO before you promise a two-week permit.
ARC mechanicals on commercial and multifamily
If ARC reviews the site, the June 11, 2024 mechanicals handout wants solar panels shown on the plot, improvement location survey, or mechanical plan with dimensions. Rooftop units must comply with Section 6-127 height restrictions. Provide a section or elevation with a cone of vision from the adjacent public sidewalk showing height and location. Screening drawings: height, shape, species, size, location. Photos of existing and proposed mechanicals. Spec sheets. Ground-mounted mechanicals: Section 6-182.1(e)(4) language in the handout requires ornamental fences and plantings that block at least 80 percent of the view, and says that to the maximum extent practical such equipment shall not be installed within 100 feet of the intersection of two public streets. If your inverter pad is at a corner, you have an ARC problem. Draw it honestly.
ARC is not the building official. A beautiful cone-of-vision sheet that never gets into the in-person building packet still leaves you unpermitted.
PE, fire, and interconnection still sit underneath the extras
Greenwich roofs still need attachment dimensions and, when the building official or the structure requires it, a Connecticut PE stamp. Fire pathways still need to be real if the fire code path applies. HOA “fill the south plane” is not an IFC exception.
Eversource interconnection (most of Greenwich) still wants PowerClerk, RRES if residential-eligible, and a one-line that matches the AHJ set. HOA color is not a PowerClerk field. Keep it off Exhibit-style utility drawings.
Do not use the site plan as a novel. How permit design works is the sequence. Connecticut design is the state hub. Greenwich extras are additional sheets, not a different physics.
Comments we answer: emailed PV application rejected, HOA notes covering dimensions, missing cone-of-vision for ARC, HDC packet without a roof plan, inverter pad in a street intersection buffer, PE letter that does not match the HOA-moved array, and a utility one-line that still shows the pre-HOA inverter location. Move the equipment once. Issue every packet.
How we split Greenwich packets so each desk sees its own sheet
Sheet G-1 AHJ site plan: property lines, building, array, meter, disconnect, dimensions the building official can scale. No covenant quotes. No plant species unless zoning already required a screen on this permit type.
Sheet G-2 roof plan: fire pathways if they apply, attachment dimensions, PE notes. HOA color callouts stay off this sheet or sit in a clearly marked “HOA exhibit, not for building review” box if the owner insists on one PDF. We prefer a separate HOA PDF.
HDC PDF: roof plan focused on visibility, street photos, cut sheets, mounting details. Cover cites § 7-147f so the commission sees the legal frame, then we still conceal the array because stipulations on location are allowed. We do not use the statute as a dare.
ARC PDF when it applies: cone-of-vision elevation from the sidewalk, screening that can hit the 80 percent view block for ground equipment, and a check against the 100-foot intersection note. Inverter pads on street corners get moved on G-1, not hidden in a shrub note.
Filing logistics: in-person building permit for PV. Email is for reroof, reside, and replacement windows on 1-2 family, not for solar. Put the appointment or counter trip on the schedule. Follow-up files to [email protected] only after the application exists, and only if the PDF prints.
HOA versus safety: if the board wants modules on a plane that deletes a fire path or overloads a rafter, we issue a written no and a layout that is legal. The owner can fight the board with that drawing. We will not stamp the illegal one.
Eversource PowerClerk uses G-1 and the one-line, not the ARC cone-of-vision. Keep utility files boring. Color of rails is not a PowerClerk field.
Calendar: HDC two-week packet rule, no August meeting on the calendar we reviewed, ARC if triggered, then in-person building, then Eversource. Promise dates only after you know which of those four are real for the parcel.
Wet versus digital PE: Greenwich in-person filing can still want a wet letter even when New Haven wants digital. Ask before the PE dates the seal. A digital-only PDF that the counter cannot print is a wasted trip to Town Hall.
If HOA guidelines arrive after the building set is already in the counter queue, do not yank the AHJ geometry to match a new color rule unless the board also moved equipment. Issue an HOA exhibit. Changing the one-line for paint is how Eversource and the building official both comment on a fake electrical change.
Ground-mount accessory arrays in Greenwich yards pick up screening, setbacks, and sometimes ARC even when the roof would have been simple. If the HOA banned the roof and pushed you to the lawn, restart zoning and the site plan. Do not reuse a rooftop supplement for a yard array. Show height at maximum tilt and the viewing cone from the street.
Send the zone, historic/HO status, HOA guidelines if any, and whether ARC applies. A Greenwich CT solar permit site plan that works is labeled layers: AHJ geometry first, covenants second. We will tell you which hearings are real before anyone draws a hedge that the building official did not ask for.
