MEP permit drawings in Colorado.

Most Colorado cities and counties adopt their own building, mechanical and energy codes. Electrical and plumbing are different: the State Electrical Board and the State Plumbing Board set statewide minimums. Colorado law also requires local governments that update their codes to meet state minimum energy standards, including electric-ready and solar-ready provisions, which has pushed many jurisdictions onto newer, stricter energy codes.

• Building & residential — IBC and IRC adopted locally; Denver enforces the Denver Building and Fire Code
• Electrical — NEC adopted statewide by the State Electrical Board, with local enforcement in many cities
• Plumbing — Colorado Plumbing Code (IPC-based) adopted statewide by the State Plumbing Board
• Mechanical & fuel gas — IMC and IFGC adopted locally
• Energy — IECC adopted locally, with state minimums and electric-ready and solar-ready requirements

Denver, Boulder and several Front Range cities have also adopted local energy and electrification requirements that go beyond the state minimum. We check your city's ordinance before designing gas equipment.

• Denver — Community Planning and Development, Development Services, enforcing the Denver Building and Fire Code
• Colorado Springs & El Paso County — Pikes Peak Regional Building Department (PPRBD), which serves the city and county
• Aurora — Building Division, Planning & Development Services
• Fort Collins — Building Services, Community Development & Neighborhood Services
• Boulder — Planning & Development Services, with Boulder's energy and electrification requirements
• Lakewood, Thornton, Arvada, Westminster & Pueblo — plus mountain communities and every other Colorado jurisdiction

Colorado Springs and El Paso County share one regional building department, PPRBD, which has its own code adoptions and submittal standards. We format Springs-area sets to match.

• Electric-ready and solar-ready provisions — circuits, panel space and conduit for future heat pumps, EV chargers and solar PV, shown on the electrical drawings.
• Cold-climate HVAC sizing — Manual J/S/D across climate zones 5 to 7, with heating-dominated loads in the mountains.
• High-altitude equipment — gas appliance derating and combustion-air details at elevation.
• Energy compliance — documentation to your city's IECC edition and local amendments.
• Snow and freeze protection — protecting outdoor equipment, condensate and piping from snow and freezing.

• Electrical — power and lighting plans, panel schedules, load calculations and single-line/riser diagrams (NEC as adopted in Colorado)
• Plumbing — fixture layouts, water supply sizing, DWV isometrics and gas piping (Colorado Plumbing Code)
• HVAC / mechanical — duct layouts, equipment schedules, ventilation and Manual J/S/D load calculations (IMC as adopted locally)
• Energy compliance — IECC compliance as adopted locally, electric-ready and solar-ready provisions, and Manual J/S/D calculations
• Fire protection — sprinkler layouts, hydraulic calculations and fire alarm plans (NFPA 13/13R/13D, NFPA 72) where your project needs them

Colorado requires sealed drawings from a Colorado-licensed professional engineer or architect for most commercial projects. Many single-family remodels and additions can be permitted without a seal. Each building department sets its own submittal thresholds.

Engineers who seal drawings in Colorado are licensed by the Colorado State Board of Licensure for Architects, Professional Engineers and Professional Land Surveyors (DORA). If your project needs sealed MEP drawings, we confirm during scoping whether a Colorado-licensed engineer can seal your discipline and scope, and we put that in writing in your quote. If we can't arrange the seal for your project, we tell you up front, so you can have your own engineer of record review and seal the set. You never pay for drawings you can't submit.

1. Free consultation — tell us about the project, the address and the permit office.
2. Send your plans — architectural floor plans in PDF or DWG (sketches work for small residential jobs).
3. Code check & fixed quote — we confirm the code editions and submittal checklist your Colorado AHJ uses, then send a fixed price and timeline.
4. Drafting & your review — residential sets usually take 5–7 business days, light commercial 7–14. You mark up, we revise.
5. Submittal & plan-review comments — you get PDF and DWG files ready to upload; if the reviewer issues comments, we revise the drawings at no extra charge until approval.
