What our electrical permit drawing package includes
Electrical permits are often rejected for the same reasons: no load calculation, a single-line diagram that does not match the panel schedule, or missing information on grounding, overcurrent protection and available fault current. We prepare permit packages that answer these questions up front.
Typical projects include residential service upgrades (for example 100 A to 200 A), EV charger circuits and load management, ADUs and additions with sub-panels, and small commercial tenant improvements. Load calculations follow NEC Article 220 methods; layouts show devices, circuits and panels on the architectural plan.
For larger building electrical sets, see electrical drafting. For PV and battery systems, see solar design services.

Electrical Permit Drawing Services standards in the USA, UK, Canada and Australia
We set up every project on the standard of the country where it will be built or manufactured. These are the references we work to most often:
| Country | Standards and codes we draft electrical permit drawing services to |
|---|---|
| USA | NEC (NFPA 70) 2023 or adopted edition – Article 220 load calculations, Article 625 EV charging, Article 230 services; local amendments |
| UK | BS 7671 (18th Edition) and Approved Document P notification; DNO requirements for supply upgrades and EV (G98/G100 where applicable) |
| Canada | CSA C22.1 Canadian Electrical Code with provincial amendments, Rule 8-200 load calculations |
| Australia | AS/NZS 3000:2018 Wiring Rules, AS/NZS 3008 cable selection, local network service and installation rules |
Engineering responsibility: we prepare drawings, models and calculations as a drafting and design-support team. Where the law in your state, province or council requires it, the final design must be reviewed, signed and sealed by the licensed engineer or architect of record for the project. We work to their markups and do not stamp drawings ourselves.
How our electrical permit drawing services process works
- 1Send your files
Upload sketches, PDFs, markups, photos, scans or a model through the quote form. Tell us the standard (US, UK, Canada or Australia) and the deadline.
- 2Fixed quote in hours
We review the scope and reply with a fixed price, the deliverables list and a delivery date. Nothing starts until you approve it.
- 3Drafting & modeling
Your project is drawn in AutoCAD, Revit, Civil 3D, SolidWorks or the software you use, on your title block, layers and templates.
- 4QA check
A second drafter checks dimensions, annotations, layer standards, sheet numbering and cross-references against your input before anything is sent.
- 5Delivery & revisions
You receive native files plus PDFs. Comments come back as markups and we revise them quickly until the set matches the brief.
Turnaround and pricing
A residential service upgrade or EV permit package is typically delivered in 1–3 business days. Every job is priced as a fixed quote after we review your files, so you know the cost and the delivery date before work starts. See how our pricing works, or send your files through the quote form for a quick estimate.
