Solar Site Plan Permit Mistakes That Delay AHJ Review

A solar site plan permit package stalls when sheet 1 cannot answer the first questions a plan checker asks: where is the lot, where is the building, where is the array, and where is the service. The roof plan can be complete. If the site plan still has no North arrow, no property lines, and an array blob that does not match the module count, the file waits.

Athol Energy includes a site plan in the standard residential and small commercial package described under permit design. We draw for Massachusetts, Rhode Island, Connecticut, New York, and Pennsylvania AHJs, which means the site plan is local even when the module is not. Service areas is the hub. This post is the comment list that actually delays those files.

Identity mistakes on a solar site plan permit

Address, parcel, and owner have to match the application form. If the portal says 15 Oak and the title block says 15 Oak Street Unit B, someone will bounce it. If the roof plan shows 24 modules and the site plan silhouette looks like 32, that is an identity fail, the same family as SLD mismatches. We walk the whole package order in how solar permit design works. Sheet 1 is not decoration. It is the sheet zoning clerks open first.

North arrow and scale are not optional graphics. Setback dimensions without a scale are numbers floating on an aerial. If you used a survey, cite it. If you used assessor lines, say so, and do not pretend they are a boundary survey when the array sits 2 feet from a disputed line. Tight lots in Cambridge, Providence triple-deckers, and Philadelphia rowhomes are where this explodes. Wide-lot western Massachusetts jobs still need the arrow.

Show the electrical service and the utility disconnect the fire company would walk to. A site plan that only shows shingles forces the reviewer into the SLD to guess which wall is which. Put a simple symbol for the meter, the main, and the PV disconnect. Those symbols must match the SLD. If the disconnect moved to the opposite side in a fire comment, both sheets move.

Setbacks people invent

Zoning setbacks, fire setbacks, and manufacturer edge distances are three different numbers. The site plan is where zoning and lot-line stories live. The roof plan is where fire paths and array edges live. Mixing them onto one unlabeled dimension is how you get a comment from planning and a comment from fire that look like they disagree. They may both be right about different things.

Do not copy a 10-foot rear-yard number from the last town. Ask this AHJ, or show the existing building setback if the array is roof-mounted and zoning is treating it as a rooftop appurtenance. Ground mounts need property-line distances, height if the town asks, and access to the equipment pad. Building code context sits in sources like the ICC code library [VERIFY URL]. Zoning is municipal. Massachusetts building-permit process overviews live on pages such as Mass.gov building permit information [VERIFY URL]. Neither page replaces the town zoning officer.

Flood, coastal, and historic overlays belong as notes when they are real. Newport historic, Stamford coastal, NYC flood maps: name the overlay if it changes the drawing. Do not add a fake flood note on an inland Worcester lot because the template had a checkbox.

Utility sketches that fight the site plan

Interconnection packages often include a simple site sketch. If that sketch puts the pad east and the AHJ site plan puts it west, one of them is wrong. Choose. Then file both as the same geometry. Production meters, new poles, and risers have to appear if the utility asked for them. Hiding a pole on the permit site plan because zoning might panic is how you fail the utility later and then fail zoning when the pole truck arrives.

HOA driveways and screening walls that are not town-required should stay off this sheet. If the town required a screen, draw the screen the PE can load. If only the HOA required it, keep it in the HOA packet. Site plans that turn into planting posters get planning comments you cannot answer with a solar PE.

Commercial lots need accessible routes, fire lanes, and sometimes lighting that is “by others.” Say by others. Do not draw a fire lane that blocks the only array access, then claim the civil engineer owns it, if you were the one who hatched it.

Comments we answer on sheet 1 without a full redesign

“Show property lines” means lines and a source note. “Show North” means a arrow that agrees with the roof plan. “Dimension array to building edge” on a roof job may belong on the roof plan; we still add a key so the site plan points at that sheet. “Provide plot plan by surveyor” is a scope change. We will not fake a PLS stamp.

If the AHJ wants parking counts or lot coverage, that is a zoning intake miss. Get the existing coverage number from the owner or survey. Do not invent lot coverage percentages. Leave a hold note until you have the number. We will not put a guessed percentage on your sheet.

Send the town checklist with the job. Call Athol Energy at +1 (209) 266-2669 when sheet 1 is the only bounce. Rush can add a North arrow and service symbol the same day. Rush cannot create a missing boundary survey.

Town overlays that belong on sheet 1

Historic districts in Newport, parts of Boston, and some Connecticut boroughs want the site plan to show the public-way elevation or at least which roof plane faces the street. If HDC is a separate filing, the AHJ site plan can stay quieter, but it still should not contradict the HDC packet. Two arrays on two packets is a stall in both queues.

Coastal A and V zones, if they apply, need a note and sometimes an elevation. Do not paste a FEMA cloud on an inland lot. If the owner thinks they are in a flood zone and the map says they are not, get the map panel reference on the sheet so the argument is documented. [CONFIRM AS OF 2026-09-19] for the panel date you cite.

HOA private roads that look like public streets confuse setbacks. If the “front” is a private way, say so. Zoning clerks will apply the wrong yard if you let the aerial look like a city street. Driveways used as fire access on commercial sites need a width if the fire company asked. Guessing a 20-foot lane because that is what the last warehouse had is how a ladder truck comment arrives after PE week.

Campus and multi-building lots need a key plan. The reviewer who has never been on site will not know which roof is “the warehouse behind the office.” Put a key, a match line, and the interconnection address. If the utility account is on a different building than the array, both buildings appear, and the POI is labeled. That is also an interconnection identity issue, not only a site-plan prettyness issue.

Snow storage, dumpster pads, and loading docks are keep-outs on C&I roofs and lots. If the array is ground mount in a paved yard, show the truck turn that operations will still need. Operations will move your fence if you ignore it, and then your as-built setbacks die. Ask the facility manager before PE. Put their keep-out on sheet 1.

Trees called out as “to be removed” need a note and, if the town wants, a separate permit. Drawing an array through a canopy you have not been allowed to cut is a site plan lie. We will hold the array until the tree story is real.

Ground-mount resubmittals should cloud only the setback that moved. If you rotate the array 10 degrees for production, every property-line dimension changes. Show the new ones. Inspectors at final will walk the fence with your site plan. If the pad is 8 feet from the line and you drew 20, the building official has a new problem even if the electrical inspector is happy.

Rooftop site plans still earn their keep when the reviewer needs to see which structure on a campus is “Building C,” which lot the interconnection is filed against, and whether the array faces a public way that triggered extra screening. Campus jobs fail identity when Building C on the site plan is Building B in the utility portal. Freeze the building name at intake.

Sheet 1 should make the lot, the building, the array, and the service obvious without a phone call. That is the whole job of a solar site plan permit drawing. Get those four things true and matching the roof plan and the utility sketch, and the rest of the set finally gets read.
