Permits and Utility Locates for Concrete Cutting in the Houston Area

Two questions should always be answered before a blade goes into the ground or a slab on grade: has someone located the underground utilities, and does this work require a permit? Both exist to prevent expensive, dangerous mistakes — a struck gas line or fiber trunk, or a stop-work order and fines. The specifics vary by jurisdiction across the greater Houston area, and this guide does not replace checking with your local authority. What it does is explain the framework — the Texas 811 one-call system, the difference between public and private utilities, and the kinds of cutting work that commonly trigger permits — so you can plan the front end of your project properly.

Two questions before the first cut

Two questions before the first cut

Any cutting or coring that could reach underground utilities — trench cutting, deep slab-on-grade work, cutting exterior flatwork, or coring through a ground-floor slab into the soil below — raises the utility-locate question. Any work that alters a structure, affects the public right-of-way, or is tied to a larger permitted project may raise the permit question. Neither is a formality: skipping the locate risks striking a live line, and skipping a required permit can halt the job and create liability. Getting both answered early keeps the project on schedule.

Texas 811 and the one-call system

Texas 811 and the one-call system

Texas uses the national 811 "call before you dig" one-call system to protect underground utilities. Before excavation — which includes cutting or trenching into the ground — a locate request is placed with 811, either by phone or online. The request notifies the participating utility operators in the area, and they mark the approximate location of their buried lines at the site using standardized color codes. Texas law provides a required advance-notice window before digging can begin, and the marks are valid for a limited period, so timing the request to the work matters. Excavating without a locate is both dangerous and, under Texas law, exposes the excavator to liability for damage.

Public locates vs. private utilities

Public locates vs. private utilities

There is a critical limit to 811 that catches people off guard: the one-call system marks the utility operators' public lines, generally up to the meter or point of service. It does not locate private utilities — the lines that run from the meter across a private property to a building, or between buildings on a site. Private irrigation, site lighting, secondary electrical feeds, private gas runs, data lines and drainage on a campus are typically the owner's responsibility to locate. On commercial and industrial sites, a private utility locator is often engaged to find these, and on-slab work benefits from GPR concrete scanning to detect conduit and pipe cast into the concrete itself.

So the complete picture is usually two efforts: an 811 request for the operators' lines, plus private locating and/or scanning for everything downstream of the meter and everything inside the concrete.

When cutting work triggers a permit

When cutting work triggers a permit

Whether concrete cutting needs its own permit depends heavily on jurisdiction and on the nature of the work. Cutting is frequently a component of a larger permitted scope rather than a standalone permit — for example, cutting a trench for plumbing falls under the plumbing work, and cutting an opening in a structural slab or wall may fall under a building permit because it alters the structure. Situations that commonly involve permitting or approvals include:

• Structural alterations — new openings in structural slabs, walls, beams or foundations
• Work in the public right-of-way, such as cutting a street, sidewalk or curb
• Cutting tied to permitted trades — plumbing, electrical, mechanical rough-ins
• Trenching and utility work that connects to public systems
• Work in floodplain or floodway areas, which carry additional Houston-area review

Because expansive clay soils make post-tension foundations common here, structural slab work often intersects both the permit question and the scanning question at once. The safest approach is to confirm requirements with the authority having jurisdiction before work starts.

Right-of-way and public property

Right-of-way and public property

Cutting concrete that is part of public infrastructure — a city sidewalk, curb, driveway approach or street — generally requires specific right-of-way permits and often traffic-control and restoration requirements set by the local public works department. These are separate from building permits and have their own process. If your project touches the public right-of-way, identify that early, because the approval timeline and restoration standards can shape the whole schedule. Sidewalk and ADA-access work is a common example — see sidewalk and ADA access cutting.

How this fits your project timeline

Locates and permits both take lead time, so they belong at the front of the schedule, not the day before cutting. Place the 811 request with enough advance notice to satisfy the required window, arrange private locating or scanning where needed, and confirm permit requirements with the jurisdiction while the scope is still being finalized. The crews we route work to can advise on where scanning fits and coordinate their cutting around located utilities, but the permit and public right-of-way approvals are generally the owner's or general contractor's responsibility to secure.

When you are ready to scope the cutting itself, request pricing or upload plans. For the reinforcement-and-utility side of the same problem, see GPR scanning before cutting.
