MEP Engineering That Gets Your Permit Approved
Mechanical, electrical and plumbing systems are where commercial permits most often get stuck. Plan reviewers want sized ducts and equipment, electrical load calculations and panel schedules, plumbing riser diagrams and fixture counts – all consistent with the architectural plans and sealed by an engineer.
SitePlaners delivers MEP plans as one coordinated package. Our engineers design the systems, our drafters produce the drawings in CAD, and a licensed PE seals every sheet. No juggling three consultants, no conflicts between the HVAC ducts and the plumbing stacks, and one point of contact from quote to permit.

When Building Departments Require MEP Plans with a PE Stamp
Engineered MEP drawings are usually required for commercial projects, tenant improvements, restaurants, multi-family buildings and larger homes. For many simple residential jobs, a licensed contractor can pull the trade permit without engineered drawings – but requirements vary widely by jurisdiction.
Tell us what you are building and where, and we will confirm which disciplines your building department needs stamped, so you do not pay for drawings you do not need.
A Typical MEP Permit Package Includes
- HVAC plans, equipment schedules and ventilation calcs
- Heating and cooling load calculations
- Electrical power and lighting plans
- Panel schedules, load calculations and one-line diagram
- Plumbing plans, riser and isometric diagrams
- Gas piping, water heater and fixture schedules
Have MEP Drawings Already? We Review and Stamp Them
Design-build contractors and drafters frequently prepare MEP layouts but cannot seal them. Send us what you have. Our engineers check sizing and code compliance, make the corrections required and apply the PE seal – usually much faster than starting over.

MEP Plan FAQs
What does MEP stand for?
MEP stands for mechanical, electrical and plumbing – the building systems that provide heating, cooling, ventilation, power, lighting, water and drainage.
Do I need stamped MEP drawings?
Usually for commercial projects, tenant improvements, restaurants and multi-family buildings. Simple residential trade work is often permitted by the licensed contractor without engineered drawings. We confirm your jurisdiction’s requirement in the quote.
What is the difference between an MEP engineer and a licensed contractor?
A contractor installs the systems; an MEP engineer designs them, sizes the equipment and certifies the design with a seal. Many building departments require the engineered design before issuing a permit.
Can you design just one discipline?
Yes. Order mechanical, electrical or plumbing plans individually, or a coordinated package of all three.
Can one firm coordinate architectural, structural and MEP?
Yes – that is our core advantage. Your full permit set is drafted and engineered by one team, which eliminates conflicts between consultants.
How quickly can I get a quote?
