Two published frames, named apart and never blended
| Frame | What it prices | 2026 band |
|---|---|---|
| Frame A (extension-specific) | driveway extension, project total | $800-$3,000 |
| Frame A (extension-specific) | average, 200 sq. ft. concrete extension | $1,900 |
| Frame B (per-square-foot addition) | added driveway area, per square foot | $3-$12 |
| Frame B (per-square-foot addition) | 200 sq. ft. addition | $600-$2,400 |
Neither frame is folded into the other. Frame A reads the project as an extension total with by-material prices; Frame B reads it as a per-square-foot addition price. The material layer prices on the by-material guide; the project-form layer on the widening vs. parking pad guide.
By-material lines, priced apart in Frame A
| Frame A line, as published | Scope | 2026 band |
|---|---|---|
| Concrete extension | per square foot | about $10 |
| Asphalt extension | per square foot | $2.50-$5 |
| Gravel extension | per square foot | $4-$5 |
| Brick extension | per square foot | $10-$15 |
| Paver extension | per square foot | $15-$30 |
The extension frame names material as the driver of its totals: an asphalt line prints at the low end and a paver line at the high end, with published extremes of $300 low and $4,900 high. Orange County quotes name two-car-garage tract homes pricing an added strip against street-parking pressure, a third car arriving, or an RV side-yard pad.
By-size lines, priced apart in Frame B
| Frame B line, as published | Scope | 2026 band |
|---|---|---|
| 200 sq. ft. addition | added area, total | $600-$2,400 |
| 400 sq. ft. addition | added area, total | $1,200-$4,800 |
| 600 sq. ft. addition | added area, total | $1,800-$7,200 |
| 1,000 sq. ft. addition | added area, total | $3,000-$12,000 |
Frame B stays apart from Frame A: its 200-square-foot band reads $600 to $2,400 against the Frame A average of $1,900 for a concrete extension of the same size, side by side and never averaged.
Two neighbours, differentiated head-on
The nearest border sits with the full-driveway pages. A new driveway replaces or installs the whole surface; this cluster prices only the added strip or pad beside the driveway you already have. The concrete driveway estimator prices a full new or replacement driveway by size, with no extension pricing in its own body; read the estimator figures there. The paver driveway page prices a full paver driveway; the paver totals there cover the whole surface, never an added strip. The sealing and sealcoating pages price surface treatments, and the gate page prices a gate across an existing opening: neither adds paved area.
Permit and prep lines, as reported cost lines only
Frame A names permits, demolition of existing pavement, and material disposal as budget categories beside its project totals, and curved shapes and grading work as labor cost factors. Each reads as its own reported cost category. Frame A prints no dollar permit band in the grounded data, and that absence prints here as published.
