## Modern Double Carport with Two Stepped Shed Roofs

The Cascade is a 2 car carport with a split-level roof. The lower shed roof covers the front half, and the upper shed roof starts higher on the tall middle posts, overhangs the lower roof and leaves a 16" open slot between the two. Daylight comes in through the slot, while rain from the upper roof drops onto the lower roof and runs to one gutter at the front.

- Both metal roofs rise 3 in 12 toward the back, so the light slot is the same 16" everywhere
- The middle row has three twin posts: a short post for the lower roof bolted to a tall post for the upper roof
- Four post lengths set all four beam heights, and the plan gives each one exactly
- 4x4 knee braces along the beams and 2x6 side braces for stiffness
- Foundation: 9 concrete piers in 3 rows, 42" deep or below your frost line, with larger piers under the twin posts
- Design basis: conventional post-and-beam practice for ground snow up to about 20 psf and ordinary inland wind, not an engineered design

## Frequently Asked Questions

### Do I need a permit for a 24x20 carport?

A 480 sq ft carport usually needs a building permit, and at 17' 4" tall this split-level carport may also meet a height limit. Show these carport plans to your building department before you buy lumber.

### What is a good size for a double carport?

This double carport has a 24' x 20' frame with two bays 11' 3-3/4" clear each. The knee braces take about 10" off each bay at 7 ft, so check tall vans and trucks.

### Does rain come through the light slot?

Straight rain does not, because the upper roof overhangs the lower roof by 24". Wind-driven rain and snow can come through, land on the lower roof and drain to the gutter.

### Can I close the light slot?

Yes, you can screw clear polycarbonate between the two fascias to close the light slot. You keep the daylight but lose the airflow.

### How do I download the PDF after purchase?

After checkout, a download link for the PDF appears on the order confirmation page and in your confirmation email. Click it to save the carport plans to your computer, tablet or phone.
