At County Permit Drawings, we engineer your comfort, safety, and efficiency through precise MEP drawings that power your project from within.
MEP (Mechanical, Electrical, and Plumbing) drawings are essential to the internal systems that make any structure livable, functional, and compliant with safety standards. These systems regulate air, water, and power making coordination critical during both permitting and construction. At County Permit Drawings, we provide MEP drawings that are fully aligned with building codes, energy regulations, and architectural layouts. Whether for new construction or remodels, our MEP sets simplify permit approvals and prevent costly site conflicts.
Our MEP drawing sets are designed for permit submittal and contractor use, fully coordinated with your architectural and structural plans
Lists codes like NEC, IPC, IMC, and IECC. Includes design criteria, system standards, efficiency requirements, and MEP-specific abbreviations.
Standardized MEP symbols, line styles, material tags, and notes for reviewer clarity and field coordination.
Displays outlet, switch, and fixture locations, circuit routing, panelboard schedules, and load calculations if needed. Also includes smoke detectors and GFCIs.
Includes supply and drainage (DWV) piping, pipe sizing, slopes, cleanouts, venting, and fixture placement. Complies with IPC or UPC plumbing codes.
Shows HVAC system layout with ducts, grilles, unit locations, tonnage, airflow direction, and thermostat placements. Designed for comfort and ventilation codes.
Shows vertical system connections for water, drain, and electrical services between floors, including service entry and equipment termination.
Provides equipment specifications for HVAC, lighting, panels, and plumbing fixtures. Supports accurate procurement and inspection.
Includes specific component callouts like water heater connections, backflow prevention, condensate drainage, and exhaust vent terminations.
To create accurate MEP drawings, we require specific information about your project
Detailed floor and roof plans to ensure mechanical, electrical, and plumbing systems are properly integrated.
Information on the desired system type, brand, efficiency rating, and location of indoor or outdoor units.
Placement of lights, switches, and control systems along with fixture specifications.
List of all plumbing fixtures, their locations, and any special water system requirements.
Locations and specifications for existing or proposed water, sewer, gas, and electrical connections.
Any state or city energy or safety standards such as NEC, IPC, IMC, or Title 24 that must be followed.
Our 5-Step Collaborative Process
Our MEP drawing workflow is efficient, responsive, and coordinated with your architectural and structural team
You share architectural floor plans, roof layouts, and your equipment preferences (e.g., HVAC tonnage, panel capacity, water heater type).
We verify which codes apply (NEC, IPC, IECC, Title 24, etc.) and confirm system sizing, zoning requirements, and energy standards.
We layout MEP systems for HVAC, lighting, power, and plumbing: factoring performance, accessibility, and code requirements.
Our team finalizes duct, circuit, and pipe routing. We integrate riser diagrams, schedules, and cross-discipline checks for consistency.
You receive a clean, organized MEP drawing set in PDF and DWG formats: ready for permit submission and contractor bidding.
MEP drawings are critical for verifying that a building’s internal systems are safe, efficient, and code-compliant. City reviewers evaluate them for energy usage, fire safety, and accessibility compliance. Without MEP plans, your permit application will likely be considered incomplete. Our drawings ensure that every circuit, pipe, and vent is accounted for helping you avoid revisions, delays, and inspection issues.
Expert in code-aligned mechanical, electrical, and plumbing designs for both residential and light commercial projects.
Coordinated drawings to reduce field conflicts, RFIs, and costly rework during construction.
Compliance with NEC, IPC, IMC, IECC, NFPA, Title 24, and regional energy codes.
We collaborate with licensed MEP engineers if stamped drawings are required in your jurisdiction.
Quick turnarounds, clean layouts, and responsive communication from design to delivery.
