If you’re planning to build a new home or remodel an existing one, submitting a full set of residential plans is one of the most critical steps in the permitting process. But what does that actually include?

In this post, I’ll break down the typical components of a complete plan set, why each one matters, and how you can avoid the common pitfalls that lead to permit delays.

Why You Need a Complete Set of Plans

Your local building department uses your plans to:

• Verify compliance with local building codes
• Confirm zoning requirements
• Ensure structural and energy efficiency
• Assess life safety elements

An incomplete submittal often leads to corrections, delays, or even rejected applications.

What’s Included in a Full Residential Plan Set?

Here are the most common components you should expect to prepare:

1. Cover Sheet

• Project address and parcel info
• Designer/owner contact information
• Code references (e.g., IRC, IBC, CBC)
• Sheet index and drawing list
• Vicinity map and zoning data

2. Site Plan

• Property lines, setbacks, easements
• Building footprint and hardscape
• Utility lines and drainage
• North arrow and scale

3. Floor Plans

• Room layouts with dimensions
• Window and door sizes
• Wall types (interior vs. exterior)
• Basic notes on materials or finishes

4. Roof Plan

• Slope directions, valleys, ridges
• Overhangs and roof materials
• Skylights or mechanical units

5. Exterior Elevations

• Views of all sides of the structure
• Grade lines and finish materials
• Height measurements (e.g., top of ridge, plate height)

6. Building Sections

• Cut-through drawings showing structure
• Wall assemblies, ceiling heights, roof-to-foundation detail
• Insulation and energy envelope locations

7. Structural Plans

• Foundation layout and details
• Floor and roof framing plans
• Shear wall and hold-down schedules
• Notes or stamps by a licensed engineer, if required

8. Electrical Plan

• Light fixtures, outlets, and switches
• Panel location and circuits
• Smoke/CO detector locations

9. Plumbing & Mechanical Plans

• Fixture layouts (toilets, sinks, tubs)
• HVAC system and duct routing
• Water heater and venting

10. Energy Compliance Documents

• Often required by state or local codes
• In California, this is Title 24
• Shows compliance with insulation, window, and system requirements

Check with Your Jurisdiction

Requirements can vary widely depending on your city or county. Always download your local building department’s submittal checklist and check for:

• Soils reports
• Fire sprinkler plans
• CALGreen checklists (in CA)
• Engineering calculations
