Two published frames, named apart and never blended
| Frame | What it prices | 2026 band |
|---|---|---|
| Frame A (professional-install totals) | single-car 12x20 install total | $2,400-$7,200 |
| Frame A (professional-install totals) | double-car 20x20 install total | $4,000-$12,000 |
| Frame B (per-square-foot installed) | metal carport, per square foot installed | $8-$20 |
| Frame B (per-square-foot installed) | 12x20 installed total | $2,000-$4,800 |
Neither frame is folded into the other, and no line is averaged into a blended figure. Frame A reads the project as a professional-install total by size class; Frame B reads it as a per-square-foot installed price. The configuration layer prices on the attached vs. freestanding guide; the material layer on the metal vs. wood guide.
Size-class lines, priced apart in Frame A
| Size line, as published | Frame | 2026 band |
|---|---|---|
| Single-car, 12x20 | Frame A | $2,400-$7,200 |
| Double-car, 20x20 | Frame A | $4,000-$12,000 |
| Triple, 30x20 | Frame A | $6,000-$18,000 |
| RV, 18x36 | Frame A | $6,480-$19,440 |
| Installer labor, per hour | Frame A | $35-$80 |
Size class is the first split in the professional-install frame, and labor prints apart from the totals in two published forms: hourly at $35 to $80 and per square foot at $4 to $8. Orange County quotes name the local shapes: side-yard RV, boat, and extra-car storage on suburban lots.
Per-square-foot lines, priced apart in Frame B
| Size line, as published | Frame | 2026 band |
|---|---|---|
| Metal carport, per square foot installed | Frame B | $8-$20 |
| 12x20, one car | Frame B | $2,000-$4,800 |
| 18x20, two cars | Frame B | $3,000-$7,200 |
| 20x20, two cars | Frame B | $3,200-$8,000 |
| 30x20, three cars | Frame B | $4,800-$12,000 |
Frame B prices metal only, with delivery and installation on level land included as published. Its totals stay apart from Frame A: a 20x20 reads $3,200 to $8,000 here and $4,000 to $12,000 there, never averaged.
A patio cover and a garage are different purchases, differentiated head-on
Two borders sit nearest this cluster. A patio cover shelters people: a roofed cover over a patio slab, priced as a patio project. A garage encloses a car behind walls and a door. This cluster prices the open-post carport structure only, a roof on posts over a driveway bay. The nearest live neighbours are the sunroom vs. patio cover guide, which prices a patio cover as its own project, and the ADU cost guide, which prices a garage and ADU project as its own enclosed project, never a carport.
Permit and HOA lines, as reported cost lines only
Frame A prints permit lines at $100 to $500 as published, apart from its totals and labor lines. HOA lines print in neither frame as a published band, and this guide prints none: an HOA line on a quote is a local line.
