Permits, culverts, and who to call

The single most useful thing to establish before any concrete is ordered is who has to be involved. Get it right and it is a phone call. Get it wrong and it is an approach that has to be rebuilt, which is the expensive version of the same conversation.

Inside Conroe city limits

Work in the public right of way, and anything tying a private drive into a city street, runs through the City of Conroe. The department that handles residential permits and inspections is Building Inspections and Permits, which describes its role as administering and enforcing building codes and regulations. The city has moved permit applications, inspection scheduling, payment, and project tracking onto an OpenGov portal, and also accepts applications by email or in person at the permits office.

Separately, the city Engineering department handles site development, drainage, and clearing and tree preservation permits, and directs applicants to Appendix A of the City of Conroe Code of Ordinances for the fee schedule. Where a project involves clearing or affects a protected tree, that is a distinct permit from anything the building department issues, which is worth knowing if a driveway route runs past a large tree.

Whether your particular driveway needs a permit is an address-and-scope question rather than a general one, and the honest answer is that the permit counter is the authority on it. A resurfacing job that touches nothing outside the property line is a different case from a new approach cutting into a city street. Ask before demolition rather than after.

Outside the city, on a county road

Unincorporated Montgomery County works differently. There is no city permit counter, and a driveway that connects to a county road across a bar ditch is handled by the commissioner precinct that covers the address. Montgomery County Engineering handles the drainage side, including sign-off requirements tied to the amount of disturbed area on a project.

The precincts publish different arrangements, so the precinct matters more than the county.

Precinct 3

Precinct 3 publishes a culvert installation policy setting out a clear division of work. The resident contacts the precinct office for the correct culvert size, has the pipe on site and the location marked, and contacts the office to enter the work into the system. The precinct then verifies the location is ready, submits the underground utility locate request through 811, and sets the culvert to proper grade with cement-stabilised sand. Locates typically take forty-eight to seventy-two hours, and the precinct states it will set the culvert within three to seven business days under normal conditions, weather permitting.

Installation is charged per foot and invoiced on completion. The published rates are $25 per foot for a single culvert up to twenty-four inches in diameter and $30 per foot above twenty-four inches; $30 and $35 per foot respectively for a double culvert; and $35 and $40 per foot for a triple. The precinct also states plainly that no driveway-type material is provided, meaning dirt, rock, or anything else that goes on top. The precinct lists a contact number for culvert enquiries on that same policy page.

Precinct 4

Precinct 4 publishes a different arrangement. The property owner marks the driveway location before inspection, a Precinct 4 inspector visits the site and determines the required pipe size and materials, and the property owner is responsible for installing the culvert and driveway.

What that means in practice

• Find out which precinct covers the address before anything else. It changes who does the work and who pays for what.
• Do not buy pipe until the precinct has specified the size. The size is set by the ditch, not by preference, and the wrong diameter is expensive scrap.
• Build the concrete to the set culvert grade, not the other way round. The pipe goes in first.
• Budget the precinct charge separately from the concrete quote. It is not the contractor's line item.
• Allow for the locate window. Three to seven business days after locates clear is a real part of the schedule.

Contractor licensing in Texas

This surprises people who have moved from other states. Texas does not issue a statewide general contractor or residential contractor licence, and concrete work is not licensed at the state level. There is no state number to look up for this trade, and any site claiming to verify a Texas concrete contractor's state licence is describing something that does not exist.

What does exist is local. Cities can require contractors to register with them in order to pull permits, and those requirements vary considerably from one Texas city to the next. Some require annual registration with proof of liability coverage; others require nothing at all. For a specific job, the permit counter for the jurisdiction is the place that can say what applies.

Because the state licence question has no answer here, the useful questions are different ones: what the written scope says, what liability coverage the contractor carries, how change orders are handled, and what the quote includes. Those tell you more about how a job will go than any registration number would.

Subdivision covenants

Separate from any government process, a great many Montgomery County subdivisions have covenants that speak to driveway materials, colours, and finishes, particularly in master-planned communities. That is an association question rather than a permit question, and it is far easier to confirm before a decorative finish is chosen than to argue about after the concrete has set.

A sensible order of operations

1. Establish whether the property is inside Conroe city limits or in unincorporated county.
2. If in the county, identify the commissioner precinct and call them about the crossing.
3. If in the city, call Building Inspections and Permits about the specific scope.
4. Check any subdivision covenants that apply to materials and finish.
5. Get the culvert sized and, in Precinct 3, scheduled.
6. Then get concrete quoted, with the tie-in elevations known.
