MEP Drawings for Permits
Many permits now require separate mechanical, electrical and plumbing sheets rather than a note that work will be "per code". MEP drawings show what's being installed, how it's sized and how it fits around the structure, and a coordinated set avoids the field clashes that cause change orders.
We prepare MEP drawings for additions, ADUs, remodels, panel upgrades, tenant improvements, restaurants and new construction.
- 3–7 days
- 98% first-time approval
- PE stamp in all 50 states

How it works
- 01
Send your project details
Address, a sketch or photos, and what you want to build. We confirm your city's requirements before drawing.
- 02
We draw and code-check
Your set is drafted to your jurisdiction's adopted code and checked the way a plan reviewer would check it.
- 03
You submit, we support
You get a permit-ready set, and we respond to any plan-check comments until it's approved.
Drawings delivered in 3–7 days. City review time after submission depends on your jurisdiction.
Frequently asked questions
Do residential permits need MEP drawings?
It depends on the jurisdiction and scope. Many accept notes for small changes but require full plans for additions, ADUs, panel upgrades and new systems. We confirm what your city needs before drawing.
Do you do electrical load calculations?
Yes. Load calcs are often required for panel upgrades, ADUs and EV chargers, and we include them with the electrical plan.
Can you match MEP to another designer's drawings?
Yes. Send us your architectural set and we'll prepare MEP sheets that are coordinated with it.
Are your MEP drawings stamped?
Where your jurisdiction requires an engineer's seal on MEP sheets, we provide it.
Already have drawings that just need a seal? See our PE stamp & seal review.
