Concrete Driveway Replacement in Plano, TX

Why a concrete driveway in Plano needs a permit now

The city's 2024 residential code, Ordinance No. 2025-6-15, went live on August 1, 2025. Its list of permit-exempt work now reads "[Deleted.]" at item 5, the spot where the model IRC lists sidewalks and driveways. A new pour no longer hides behind that exemption. The city's When is a permit required? handout calls out two jobs by name: installing or replacing a driveway approach, which it describes as the portion connecting to the street, and installing a circular layout.

When a replacement reaches the curb, the approach permit comes from the Building Inspections Department. You hand in a completed application plus two copies of the site plan, and the fee for a sidewalk or approach in the right-of-way, new or replacement, is $75 under the fee ordinance posted for January 2, 2026. If the work stays entirely behind your property line, that is a separate question. Call Building Inspections first and ask how it wants it handled, before anyone breaks the slab. Our north suburbs permit guide lines the city up against its neighbors, the concrete driveway service page walks through the whole job, our Plano page covers the rest of our work in town, and you can request a free estimate whenever you are ready.

Bar by bar: the city's approach spec for a Plano driveway

Plano's driveway approach permit requirements work like a short spec sheet. Width runs from 12 feet at minimum to 24 feet at most, and the curb return radius is 5 to 10 feet. The slab is a minimum of 6 inches of 3,000 psi concrete, reinforced with #3 bars at 24 inches on center each way and held up on chairs.

• The street gets sawcut all the way through, 18 inches from the back of curb, and the curb and gutter come out as an 18-inch strip.
• #4 deformed dowels, 24 inches long, go into holes drilled in the street at 24 inches on center. The private slab ties into the approach with the same bars.
• Any smooth dowel has to be lubricated so the joint can slide.
• New pavement sits on subgrade compacted to 95 percent. Loose dirt is out, and an over-dug spot is refilled only with approved sand or gravel.
• The 4-foot public sidewalk holds a 2 percent cross slope straight through the driveway, with an expansion joint at the walk, and no cutting goes past the property line projection.

The permit closes after two inspections: the pre-pour inspection and the final building inspection. The permit holder requests both through eTRAKiT. A re-inspection costs $75 for the first return trip and climbs to $150 by the fourth, so the steel, chairs and dowels on a concrete driveway in Plano need to be right when the inspector first walks up.

What It Costs

DFW ranges for a reinforced Plano driveway. The firm figure arrives in a free written estimate after the site visit.

Worked example: a 22 by 24 driveway is 528 sq ft x $7 to $12 = $3,696 to $6,336, before tear-out. Plano's $75 right-of-way approach fee is separate from that. For how Plano compares with other metro cities, see our DFW driveway cost guide; your number comes from a free written estimate.

Alley access, circular layouts and the 55 percent paving cap

Does your garage open onto an alley? The alley approach uses the same 12 to 24 foot width and the same 6 inches of 3,000 psi mix with #3 bars at 24 inches, but the ties differ. The bars are drilled 12 inches deep into the alley at 24-inch centers, using 24-inch #4 deformed dowels. At the property line the joint becomes an expansion joint with #4 smooth dowels, sealed with hot-poured rubber joint compound, and the 5-foot radius rule drops away. The detail also has one blunt line: water meters are not allowed in the driveway, so a meter sitting in the path has to be handled before the pour.

The city lists a circular driveway as its own permit item, but zoning decides whether one fits, not the concrete. In single-family and two-family districts, front-yard pavement may not exceed 55 percent of the area between the property line and the building face (Zoning Section 3-1110, as cited on the approach handout). A horseshoe added to an existing concrete driveway in Plano can blow past that cap fast, so we measure the area at the site visit and put the math on the estimate. The city also points owners to their HOA for deed restrictions and covenants; our HOA approval guide covers that packet.

Houston Black clay under two-thirds of the ground NRCS sampled in Plano

Out of 30 random NRCS sample points inside the city's 2020 Census boundary, 20 landed on Houston Black clay, or 67 percent. Its main phase has a linear extensibility of 12 percent, which sits in the NRCS very high shrink-swell class, and the Texas rating for dwellings on slab is Very limited. Austin silty clay turned up at 4 points with a lower 5.1 percent, and Tinn clay, occasionally flooded, at 2 points with 11 percent. For a concrete driveway in Plano, remember this one: every soil in the sample is rated Very limited for local roads and streets.

So the city's detail leans on compaction, dowels and chaired steel rather than thickness alone. On our end, the work means stripping organic topsoil, compacting what is left, holding the bars up in the slab instead of letting them lie on dirt, and placing joints where the clay will crack the slab anyway. Our expansive clay guide covers the mechanics. FEMA mapping at the same points came back 90 percent Zone X minimal hazard and 3 percent in an AE floodway, so check your own address if your lot backs to Rowlett Creek or the green belts near Oak Point Park and Nature Preserve.

How Your Job Goes

1. Consultation and design

   We measure the driveway and the front-yard paving area against Plano's 55 percent cap, note any meter and alley, and write the spec into a free estimate.

2. Planning and preparation

   Next come the approach permit with two site plan copies, the utility locate, tear-out, a sawcut 18 inches from the back of curb, drilled dowels, and steel on chairs for the pre-pour inspection.

3. Installation and completion

   Then we pour, cut the joints, set expansion material at the walk, pass the final building inspection and leave the street clean.

Replacing a concrete driveway in Plano's 1980s and 1990s neighborhoods

Census Bureau 2024 five-year estimates put Plano's median year built at 1993. Of 117,686 housing units, 28.6 percent went up in the 1990s, 21.6 percent in the 1980s, and 18.4 percent, about 21,662 homes, before 1980. If your house sits on a street off Spring Creek Parkway, Parker Road or Los Rios Boulevard and is one of those older homes, the job is tearing out the slab the builder poured, not a first pour on raw dirt.

A tear-out also changes the price math. Tear-out and haul adds $1.50 to $4 per sq ft on top of the new slab, depending on how thick the old concrete is and how much steel is in it. When the old approach is coming out too, the city's sawcut line 18 inches from the back of curb, the gutter strip and the doweled tie into the street all land on the estimate. A heavier 6-inch section for a boat or trailer strip adds $1.50 to $3 per sq ft. Adding onto the house at the same time? Plano wants every new foundation or footing designed and sealed by a Texas-registered engineer; see our Plano foundations page. Whatever you are replacing, a concrete driveway in Plano gets its firm price from the written estimate after we see the slab.
