Discipline 03 / 05
MEP Drawings
“At County Permit Drawings, we engineer your comfort, safety, and efficiency through precise MEP drawings that power your project from within.”
01Overview
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.
02Deliverables
What we provide
Our MEP drawing sets are designed for permit submittal and contractor use, fully coordinated with your architectural and structural plans
02
Legends & Symbols
Standardized MEP symbols, line styles, material tags, and notes for reviewer clarity and field coordination.
03
Electrical Drawings
Displays outlet, switch, and fixture locations, circuit routing, panelboard schedules, and load calculations if needed. Also includes smoke detectors and GFCIs.
04

05
Mechanical/HVAC Drawings
Shows HVAC system layout with ducts, grilles, unit locations, tonnage, airflow direction, and thermostat placements. Designed for comfort and ventilation codes.
06
Riser Diagrams
Shows vertical system connections for water, drain, and electrical services between floors, including service entry and equipment termination.
07
Schedules
Provides equipment specifications for HVAC, lighting, panels, and plumbing fixtures. Supports accurate procurement and inspection.
08
Details
Includes specific component callouts like water heater connections, backflow prevention, condensate drainage, and exhaust vent terminations.
03Project inputs
What we need from you
To create accurate MEP drawings, we require specific information about your project
- 01
Architectural Plans
Detailed floor and roof plans to ensure mechanical, electrical, and plumbing systems are properly integrated.
- 02
HVAC Preferences
Information on the desired system type, brand, efficiency rating, and location of indoor or outdoor units.
- 03
Lighting Plan
Placement of lights, switches, and control systems along with fixture specifications.
- 04
Plumbing Fixture List
List of all plumbing fixtures, their locations, and any special water system requirements.
- 05
Utility Info
Locations and specifications for existing or proposed water, sewer, gas, and electrical connections.
- 06
Applicable Codes
Any state or city energy or safety standards such as NEC, IPC, IMC, or Title 24 that must be followed.
04How we work
From first sketch to approval
Our MEP drawing workflow is efficient, responsive, and coordinated with your architectural and structural team
- 01
Project Input
You share architectural floor plans, roof layouts, and your equipment preferences (e.g., HVAC tonnage, panel capacity, water heater type).
- 02
Code Compliance Review
We verify which codes apply (NEC, IPC, IECC, Title 24, etc.) and confirm system sizing, zoning requirements, and energy standards.
- 03
System Design
We layout MEP systems for HVAC, lighting, power, and plumbing: factoring performance, accessibility, and code requirements.
- 04
Coordination & Detailing
Our team finalizes duct, circuit, and pipe routing. We integrate riser diagrams, schedules, and cross-discipline checks for consistency.
- 05
Final Delivery
You receive a clean, organized MEP drawing set in PDF and DWG formats: ready for permit submission and contractor bidding.
05Role in permit drawings
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.
