What Portsmouth does to a electrical bid
Four distinct seasons, cold winters, historic building stock. Temperatures swing 15°F - 85°F, rainfall runs 40-50 inches, and inspectors here are working off IRC R301.2 / IECC Zone 5–6. None of that shows up on a plan symbol legend — but it changes your fastener schedule, your waste factor, and whether the building department signs off on the rough.

Subbing under a licensed GC is one workaround, but on direct-to-owner jobs the homeowner can void the contract if you don't hold the card.

Stuff Portsmouth electricians ask before they sign up
Does this respect NH code, or do I have to re-cut every quantity?
Counts assume IRC R301.2 / IECC Zone 5–6 (frost depth 48–60 in., ice-shield 36 in. past wall, historic district overlays). The takeoff doesn't pull a permit for you — that's still on whoever holds the Master Electrician License / Electrical Contractor License — but the assemblies match what NH inspectors look for.
How do you handle counting outlets, switches, and fixtures manually?
The model reads the plan once, counts symbols against your assembly library, and surfaces the count for review. You override anything that looks off before it hits the quote. For historic work in Portsmouth, the typical correction is one or two assemblies — not redoing the whole thing.
What about nor'easters bring heavy snow and wind?
Slate traditional but expensive. Architectural shingles most common. Ice and water shield required. Cedar shakes historic but fire risk. Snow guards needed.
