Boxed-Eave Peak
A peaked, boxed-eave roof line gives a more residential appearance while keeping steel framing strength.
The Residential Look
Boxed-eave carports use an angular A-frame roof for a more residential appearance than a rounded standard roof. The roof panels still run horizontally, which keeps this style distinct from a vertical roof.
Residential Styling
A peaked boxed-eave line that matches nearby homes and garages.
Horizontal Panels
Panels run front-to-back; standard for carports under 36' long.
Steel Framing
14-gauge or 12-gauge framing built for NorCal conditions.
Sizing
What Size do You Need
Sizing comes down to the vehicle footprint plus clearance for doors and movement. Use the matrix to find your width.
Width Selection Matrix
Sizing based on standard vehicle footprints
| Width | Best Use Case | Capacity |
|---|---|---|
12' Wide | Single Car, Truck, or SUV | 1 Vehicle |
18' Wide | Two Compact Cars or One Large RV | 1-2 Vehicles |
20' Wide | Two Mid-Size Sedans | 2 Vehicles |
22' Wide | Two Full-Size Cars | 2 Vehicles |
24' Wide | Two Full-Size Trucks, SUVs, or Vans | 2 Vehicles |
26' Wide | Three Compact/Mid-Size Cars | 3 Vehicles |
28' Wide | Three Mid-Size Cars | 3 Vehicles |
30' Wide | Three Full-Size Cars, Trucks, or SUVs | 3 Vehicles |
Pro Tip: Door Swing Clearance
While these dimensions list vehicle capacity, we always recommend measuring your vehicle with the doors open. A 12' wide unit is a tight fit for a full-size truck with extended mirrors.

Horizontal A-Frame Questions Answered
What is a horizontal A-frame carport?
A boxed-eave carport with a peaked, more residential roof line, where the panels run horizontally front-to-back. It gives a home-like appearance at a modest step up from a standard rounded-eave roof.
How much does a horizontal A-frame carport cost?
Pricing depends on size, leg height, gauge, and site conditions. Use the calculator for an instant estimate, then we confirm an official quote for your build.
How is it different from standard and vertical roofs?
Standard uses a rounded eave; horizontal A-frame adds a boxed-eave peak for a more residential look with panels still running horizontally. Vertical runs panels ridge-to-eave and is the upgrade for snow, debris, or spans over 36' long.
Do I need a permit for a carport in California?
Permit requirements depend on the structure, placement, foundation, and jurisdiction. The customer handles permits and coordinates required inspections. Norcal Carports can coordinate pricing from A&A Engineering when engineering is required.
Do you pour concrete or do foundation work?
No — Norcal Carports does not perform concrete or any foundation work. We provide site-appropriate anchoring but do not install foundations. See our foundation requirements guide to prep your site.
