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.
Retail, office, medical and restaurant build-outs with full MEP design and stamping.
Hood exhaust, make-up air, grease interceptors, gas piping and kitchen equipment power.
Unit and common-area HVAC, electrical service and plumbing risers for apartments and condos.
Custom homes, additions and ADUs where the jurisdiction requires engineered MEP drawings.
MEP upgrades and code analysis when a space changes occupancy classification.
Existing MEP drawings from your contractor or designer reviewed, corrected and sealed.
Live chat puts you directly in touch with the team that will draw and seal your plans. Ask anything – span tables, load calculations, seal requirements in your state, turnaround – and get a real, technical answer while you are still on this page.

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.
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.
Share your address, scope and any sketches, photos, old plans or plan-check comments - by quote form or live chat.
We reply in 5-10 minutes with scope, fixed price and delivery date. No work starts until you approve.
Our team draws your plans in CAD and completes the structural or MEP design and calculations the code requires.
A licensed engineer reviews and seals the set. You receive permit-ready PDFs (and CAD files if needed).
Choose a single discipline or a fully coordinated MEP package. Every sheet is drafted in CAD and sealed by an engineer licensed in your state.

Duct layouts, equipment schedules, ventilation and heating/cooling load calculations.

Power, lighting, panel schedules, load calculations and one-line diagrams.

Fixture layouts, DWV risers, isometrics, water heater and gas piping plans.
MEP stands for mechanical, electrical and plumbing – the building systems that provide heating, cooling, ventilation, power, lighting, water and drainage.
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.
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.
Yes. Order mechanical, electrical or plumbing plans individually, or a coordinated package of all three.
Yes – that is our core advantage. Your full permit set is drafted and engineered by one team, which eliminates conflicts between consultants.
