Rough vs. Final: Scheduling Electrical Inspections So the GC Never Waits on You

On a job schedule, your inspections are gates: insulation and drywall can't start until the rough passes, and close-out money doesn't move until the final does. When a gate stays shut, the whole job waits — and it waits on you, by name. The subs who never get that phone call aren't lucky. They schedule differently.

What the rough is

The rough inspection covers everything that's about to disappear: wiring run, boxes set, connections made up, walls and ceilings still open. Massachusetts is explicit that electrical work can't be concealed or covered from view until the wiring inspector has inspected it — so the rough isn't a formality, it's the legal precondition for the next trade's work. The GC knows it, which is why a delayed rough shows up on the schedule with your company's name next to it.

What the final is

The final comes at completion: devices in, fixtures hung, plates on, panel labeled, everything energized and finished. Service upgrades and temporary power typically need inspection approval before the utility connects. The passing final, recorded by the town, is what closes the permit — and until it's recorded, you're carrying an open permit that can resurface at a closing years later. On plenty of jobs it's also what releases retainage and final payment, which makes the final the cheapest collections tool you own.

How the notice window actually works

Under the state code, once you've given the inspector proper notice, the inspection is expected within 72 hours for installations — 24 hours for excavation work — with Saturdays, Sundays, and holidays excluded. Read that carefully, because both halves matter:

• The clock starts when you call.Not when the work is done — when notice is given. A rough that's ready Thursday but called in Monday didn't lose a weekend, it lost four days of somebody's schedule.
• Up to three business days is real time.Call Thursday and the window can legitimately run into the middle of next week. Build that into what you promise the GC — the schedule-killer isn't the window itself, it's the sub who told the GC “inspector's coming tomorrow” without having booked anything.

Scheduling habits that keep you off the critical path

• Learn each town's method before you need it. Portal, phone line, email, a paper card — and learn the inspector's rhythm. Bigger cities inspect daily; in smaller towns the wiring inspector may hold limited hours or set inspection days. That one fact changes when “ready for rough” needs to happen.
• Walk the job before you call. Ten minutes with your own punch list catches the loose staple work, the missing connections, the box that never got made up. A failed rough is the most expensive kind of delay: fix, re-notice, wait out another window — and every following trade reshuffles around you.
• Tell the GC the date the moment you have one. The GC isn't actually asking for a fast inspection — they're asking for a date they can sequence around. A firm Thursday beats a hopeful tomorrow every time.
• Batch same-town work.If you've got three jobs in one town, lining their inspections up on the same day makes the inspector's trip worth it and builds the kind of goodwill that gets your emergency squeezed in later.
• Book the final the week the work completes.The crew's knowledge is fresh, the site is open, the punch items are small. Every week after that, the final gets harder to schedule and easier to forget — and forgotten finals become open permits.

Bigger jobs: ask about phased inspections

On a larger job, “the rough” is rarely one visit. Floors finish at different times, and holding every ceiling open until the whole building is wired helps nobody. Most inspectors will work with a sensible phasing — a rough per floor, per unit, per area — but how they want it sliced is their call, so have that conversation at the start of the job, not the week the GC wants the third floor closed. A phasing plan agreed up front turns five potential arguments into five routine appointments.

The quiet-permit trap on long jobs

On a job that stalls — financing hiccups, redesign, a GC juggling phases — months can pass with no inspection activity, and permits that sit inactive too long can lapse. Passing a real inspection at a real milestone is what shows the town the job is alive, so on a slow job, don't sit on a phase that's ready for its rough.
