size, finish, sales tax and curb cut rules
HOW MUCH DOES A CONCRETE DRIVEWAY COST?
Angi puts a typical concrete driveway in Seattle at $3,000 to $16,110, with an average of $7,110, or $8 to $20 per square foot. A 20-by-20-foot driveway (400 sq ft) runs $2,800 to $5,200 in Angi's Seattle table, and removing an old driveway averages $1,800. Angi doesn't publish separate figures for Kent or Bonney Lake. In Washington, sales tax applies to the whole contract, and work on the driveway entrance from the street needs a city permit.
Concrete driveway cost by size
| Size | Sq ft | Seattle (Angi) | Seattle average | National (Angi) |
|---|---|---|---|---|
| 10 × 20 ft (one car) | 200 | $1,400–$2,600 | $2,000 | $1,600–$3,000 |
| 12 × 24 ft | 288 | $2,000–$3,750 | $2,875 | $2,300–$4,300 |
| 20 × 20 ft (two cars) | 400 | $2,800–$5,200 | $4,000 | $3,200–$6,000 |
| 24 × 24 ft | 576 | $4,030–$7,490 | $5,750 | $4,600–$8,600 |
| 24 × 36 ft | 864 | $6,050–$11,250 | $8,650 | $6,900–$13,000 |
Angi's Seattle size table runs a little below its national table, but its Seattle average for a whole project ($7,110) is higher than the national average (about $6,400). Nationally, Angi says labor is about half the total, at $2 to $10 per square foot.
Removal and prep in Seattle
- Removing old concrete: $2 to $6 per sq ft, averaging $1,800 for a whole driveway.
- Leveling: $1 to $3 per sq ft. Sub-base: $1 to $2 per sq ft.
- Angi says Seattle's "soggy soil" and constant rainfall, along with demolition and prep, can drive up costs significantly.
Cost by finish
| Finish | Per sq ft | Average |
|---|---|---|
| Plain | $6–$8 | $7 |
| Broom finish, textured, colored, exposed aggregate, salt finish | $8–$12 | $10 |
| Stamped, slate or imprinted | $12–$18 | $15 |
| Saw cut or stained | $18–$20 | $19 |
Thickness, reinforcement and other extras
- Thickness. Angi says 4 inches is the common depth; heavier use may call for 6 inches, and heavy vehicles or several cars may need 8 inches. Ask each quote to state the thickness.
- Rebar. Angi lists an average of $1.40 per linear foot ($0.70 to $2.55), not counting labor.
- Apron (the part that meets the street): $1,530 to $4,320.
- Sealer: $16 to $50 per gallon, covering 150 to 300 sq ft per gallon.
- Heated driveway system: $3,000 to $8,700.
- Repair instead of replace: Angi lists $3 to $25 per sq ft for repairs, against $8 to $20 for replacement.
- Lifespan: 25 to 30 years with proper maintenance, according to Angi, and less with heavy vehicle use.
Concrete vs. asphalt
| Driveway | Per sq ft (Angi) |
|---|---|
| Concrete | $8–$20 |
| Asphalt, new | $7–$13 |
| Asphalt, replacing an old driveway | $8–$15 |

Sales tax: example for a 400 sq ft driveway
The Department of Revenue says construction for a homeowner is subject to retail sales tax on the gross contract price, so labor is taxed along with materials. The rate is the one where the work is done.
| Angi Seattle price (20 × 20 ft) | Seattle, 10.55% | Kent, 10.40% | Bonney Lake, 9.60% |
|---|---|---|---|
| $2,800 | $3,095 | $3,091 | $3,069 |
| $4,000 (average) | $4,422 | $4,416 | $4,384 |
| $5,200 | $5,749 | $5,741 | $5,699 |
City rules
Seattle
- New driveway through the curb. SDCI says you need a curb cut permit "when you make a new driveway in an existing sidewalk curb." It must meet SMC 23.54.030.F and the site plan standards of Tip 103. With a house or duplex project, it's part of the construction permit; on its own, you apply through SDOT.
- Permit types. SDOT's Client Assistance Memo 2209 (revised August 20, 2018) lists concrete driveways and curb cuts along a street with existing curbs as permit Type 26, and driveways with no curb as Type 25, available over the counter from SDOT.
- Grades and trees. SDOT requires driveways to match street or alley grades. Trees in the right-of-way are removed only when "absolutely required for access"; a curb cut permit doesn't cover landscaping, which needs a separate SDOT Urban Forestry permit.
- The sidewalk is yours to maintain. See sidewalk repair cost in Seattle.
Kent
- Street use permit. Kent City Code 6.07 requires a street use permit to use a public place, including streets, sidewalks and planting strips, for private purposes, and defines a driveway as the part of a public place that gives vehicle access through a depression in the curb.
- Insurance. Kent's Street Use and Street Cut permit checklist says contractor's liability insurance is required for any work in the public right-of-way and must name the City of Kent as additional insured.
- Ask the Kent Permit Center (400 W. Gowe) whether your project needs a permit before work starts.
Bonney Lake
- Road approach permit. Bonney Lake Municipal Code 12.20.020 says no one may build, repair or alter an approach to a city road "without first obtaining a road approach permit from the city."
- Fee. BLMC 12.20.060 lists $50 for a residential approach (Ord. 826, 1999). Confirm the current fee with the City.
- Standards. BLMC 12.20.040 says the road approach standards are available at City Hall.
Before you sign
- Get the size, thickness, base, reinforcement, finish and removal of the old driveway in writing.
- Check the contractor's registration with L&I. Keep the first payment small: contractor down payments.
- Ask for lien releases at the end: construction liens in Washington.
