Attached vs. Freestanding Carport Cost Guide
The configuration layer prints inside the size frames: Frame A prices a single-car install total at $2,400 to $7,200 and labor at $35 to $80 per hour, while Frame B prices metal at $8 to $20 per square foot installed. This guide prices the configuration layer apart.

The configuration layer, priced apart in both frames
| Frame | Line | 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 |

Every figure here sits inside its own frame, never averaged. Neither frame prints a separate attached band or freestanding band: both price size class, and configuration reads as the line scope named on the quote. The project whole prices on the carport installation hub; the material layer on the metal vs. wood guide.
Attached lines, as published cost lines only
| Attached line | Frame reading | 2026 band |
|---|---|---|
| Installer labor, per hour | Frame A, as published | $35-$80 |
| Installer labor, per square foot | Frame A, as published | $4-$8 |
| Permit line | Frame A, as published | $100-$500 |
| House-wall side line | cost-line category, no separate published band | named on quote |
An attached carport reads against the house wall, and its published lines are the shared frame lines: labor in two published forms, and the permit line. The wall-side line prints as a category on quotes, not as a published band in either frame.
Freestanding lines, as published cost lines only
| Freestanding line | Frame reading | 2026 band |
|---|---|---|
| Post lines, full perimeter | cost-line category, no separate published band | named on quote |
| Foundation lines | cost-line category, no separate published band | named on quote |
| Delivery and installation on level land | Frame B, included as published | in the $8-$20 rate |
| RV 18x36 install total | Frame A, as published | $6,480-$19,440 |
A freestanding carport stands apart from the house, and quotes name its post lines and foundation lines as their own cost lines. Frame B includes delivery and installation on level land inside its published rate. The RV class prints in Frame A at $6,480 to $19,440.
Permit and HOA lines, as reported frame lines only
Frame A prints permit lines at $100 to $500 as published, and the line prints the same in attached and freestanding scope: no frame splits it by configuration. HOA lines print in neither frame as a published band, and this guide prints none: an HOA review line named on a quote is a local line, read apart from both frames.
Reading a configuration quote, as reported lines only
A configuration quote should name its configuration and its frame on every line: attached scope with its wall-side and labor lines, or freestanding scope with its post and foundation lines shown apart.
- Configuration named on every line, frame named beside it
- Post and foundation lines shown apart in freestanding scope
- Permit lines read at the published Frame A band
- HOA lines read as local lines, never as frame lines
