US electrical drafting — FAQ (cost, PE stamp, turnaround)

Common questions about our residential electrical drafting for US permit sets — cost, turnaround, stamping, files and how to start. For the full breakdown of what a set contains, see what an ADU electrical permit set contains.

How much does a residential electrical permit set cost?

A house or ADU set is $480 per plan, and the first project is free. You send one floor plan, get the complete set back, and judge it before you pay anything. Larger or multi-family projects are quoted per building once we have seen the base drawing.

How long does it take?

Two to five working days once the base drawing checks out. The first project — the free one — runs on the same timeline. If your state's code is one we have not set up yet, the first set from that state may take a day or two longer.

Do I need a PE stamp for an ADU or single-family electrical plan?

It depends on your jurisdiction. In much of the country a residential or ADU electrical permit set can be prepared by the designer or the contractor without a professional-engineer stamp; where a stamp is required, the work has to be under the engineer of record's responsible charge — the engineer makes or reviews the engineering decisions and stamps the set. We only draft, from your decisions; we are not licensed in California, so the plans go out under your name. Confirm the stamping requirement with your authority having jurisdiction, since it varies by state and city.

Can I outsource residential electrical drafting for a US permit set?

Yes. Send the architect's floor plan; we return the electrical sheets for the permit set — single-line diagram, panel schedules, NEC load calculation, power and lighting plans — as editable DWG and PDF with the bill of quantities, usually in two to five working days. The work is prepared under your responsible charge: you make the engineering decisions, review and stamp. The first project is free.

Is outsourced drafting compatible with responsible charge?

Yes, when the engineer stays in control of the engineering. You set the design criteria and make or review the decisions — circuits, panel, service, conductor and protection sizing — and we produce the drawings, schedules and calculations from them, flagging anything that needs your call. That keeps the work under your responsible charge. What doesn't is stamping a finished design you did not direct, and that is not how we work.

What's included in the set?

A cover sheet, single-line diagram, panel schedule, a load calculation to NEC Article 220, receptacle and lighting plans, grounding and bonding, and — where fault current matters — an AIC and voltage-drop check, plus Title 24 lighting-control items in California. All of it is generated from one set of circuit data, so the panel schedule, the one-line and the load calculation always agree. The full sheet-by-sheet list is on the permit-set page.

What files do I receive?

Editable DWG and DXF for CAD, PDF for review, and the bill of quantities as an Excel file. Everything is unstamped and unbranded — nothing carries our name, in the drawing, the title block or the file properties.

Which code do you draw to?

We draw to the NEC, including California's edition of it. If your jurisdiction runs a state amendment or a different code we have not configured yet, we set it up before we quote. You confirm compliance under your responsible charge.

Whose name is on the drawings?

Yours — not ours. We work as your drafting subcontractor and deliver an unstamped, editable set, prepared under your responsible charge: you make the engineering decisions, review, stamp and sign. Publicly we stay a brand; the review and the responsibility stay with the engineer of record.

Do you work outside the United States?

Yes — we draw to the local rules of wherever the building goes up. We have the US NEC, including California's edition, set up today. For a state amendment or another country we have not configured yet, we set that standard up before we quote, so the first set from a new place may take a little longer. Tell us where the project is and we will confirm the code and the timeline.

Is this software or a service?

A service. Software such as uplan, CYPE or Revit gives you a tool to draft the set yourself; we return the finished, editable set and you review and sign it. See the side-by-side comparison.

How do I start?

Send one floor plan — DWG or DXF — and we return the complete electrical set, the first one free. You make the engineering decisions and stamp, under your responsible charge; we only draft.

This page is practical orientation; the current code edition, the authority having jurisdiction, and the review of the engineer of record always govern.
