Concrete Permit Guide for Katy & Fort Bend County, TX
Permit requirements for concrete work in the Katy area confuse many homeowners because the rules depend on whether your property falls within the City of Katy limits or in unincorporated Fort Bend County — and sometimes both jurisdictions apply to different aspects of the same project. In this post, we cover what triggers a permit, how the city and county rules differ, and what the application process looks like for common concrete projects.

Why Permits Matter for Katy Concrete Work
Unpermitted concrete work in Katy creates problems that compound over time. At resale, unpermitted improvements must be disclosed or discovered — and buyers, lenders, and title companies increasingly flag permit status for concrete work. In HOA communities like Cinco Ranch or Firethorne, unpermitted work can trigger fines and mandatory removal orders. And practically, unpermitted work bypasses the inspections that catch subbase failures, drainage problems, and reinforcement errors before they are buried under concrete.
The concrete work permit process in Katy is designed to ensure that driveways connect to streets correctly, that surface water drains away from foundations, and that slabs are built to the 2021 International Building Code as adopted by the City of Katy. This is not bureaucratic overhead — it is the mechanism that ensures the work is done correctly and that the property owner has documentation proving it was done to code.
City of Katy Permit Requirements
Within the City of Katy limits, the City of Katy Development Services department issues permits for concrete construction. The city has adopted the 2021 International Building Codes and the 2023 National Electrical Code, and permit applications are processed through the City of Katy’s Civic Access online portal.
What requires a permit within City of Katy limits:
A building permit is required for most concrete construction and property improvements including:
- Driveways (new construction and replacement)
- Sidewalks and walkways connected to public right-of-way
- Concrete patios
- Retaining walls over 4 feet in height
- Any new structure or concrete slab that connects to a structure
What typically does not require a City of Katy permit:
- Concrete repairs and crack filling that do not expand the footprint of an existing slab
- Decorative resurfacing overlays on existing slabs
- Isolated concrete pads (dumpster pads, equipment pads) under a threshold size
When in doubt, contact the City of Katy Development Services or ask your contractor to confirm before work begins. Working without a required permit can result in stop-work orders, fines, and required demo of completed work.
Fort Bend County Permit Requirements (Unincorporated Areas)
Properties in unincorporated Fort Bend County — which includes many of the master-planned communities and rural properties outside City of Katy limits — fall under Fort Bend County Engineering Department permitting. The county’s permit requirements for concrete are specific and worth understanding:
A Fort Bend County permit is required when the project involves:
- Construction of any fully enclosed structure or concrete slab equal to or larger than 400 square feet (including modifications to existing buildings)
- Installation of a driveway connection to a county-maintained roadway — this applies regardless of slab size
- Fill placement or excavation greater than 500 cubic yards per acre, and/or changes in elevation of 6 inches or more
- Any new construction that requires grading changes affecting drainage to adjacent properties
What this means practically for common projects:
- A patio under 400 sq ft on a property with no county road frontage: likely no county permit required
- A driveway connecting to a county road: permit required regardless of size
- A garage slab over 400 sq ft: permit required
- A pool patio over 400 sq ft: permit required
Fort Bend County permit applications are submitted through the county’s Engineering Department and typically take 2–4 weeks for residential projects and 4–8 weeks for commercial projects.

How to Apply for a Concrete Permit in Katy
For City of Katy projects:
- Determine your project scope (what is being built, sq footage, connection to public right-of-way)
- Create an account on the City of Katy Civic Access portal
- Submit a permit application with site plan, dimensions, and project description
- Pay the permit fee (varies by project type and size)
- Schedule the required inspections — typically a pre-pour inspection and a final inspection
For Fort Bend County projects:
- Confirm your property is in unincorporated Fort Bend County (not in a city limit)
- Prepare a site plan showing the proposed concrete work and its relationship to property lines and drainage
- Submit to Fort Bend County Engineering Department
- For driveway connections to county roads, an approach permit is required and the design must meet county road standards
- Complete required inspections
HOA Requirements:
Many Katy master-planned communities — Cinco Ranch, Firethorne, Seven Meadows, Elyson — require HOA architectural committee (ARB) approval before concrete construction begins. HOA approval is separate from and in addition to city/county permits. We recommend beginning the HOA process at the same time as permit application, as HOA review can take 2–4 weeks.
Common Questions About Katy Concrete Permits
Does a concrete driveway repair require a permit in Katy?
Most repairs — crack filling, resurfacing, sealing, patching isolated sections — do not require a permit within the City of Katy or Fort Bend County. A full driveway replacement (removing and replacing the entire slab) typically does require a permit because it constitutes new construction on the driveway footprint. When in scope doubt, we confirm permit requirements during the estimate process.
How long does it take to get a concrete permit in Katy?
City of Katy building permits for residential concrete projects typically take 1–2 weeks for straightforward applications. Fort Bend County projects take 2–4 weeks. Complex projects or those requiring additional documentation can take longer. We recommend accounting for permit timeline when planning project start dates.
What happens if I do concrete work without a permit in Katy?
Unpermitted concrete work in Katy can result in stop-work orders, fines, mandatory removal of completed work, and disclosure requirements at property sale. In HOA communities, unauthorized construction can trigger architectural violation fines. Lenders and title companies increasingly require permit documentation for improvements. Working without a required permit is not worth the risk — the permit process exists to protect the property owner as much as to enforce code.
Do I need an engineer for a concrete permit in Katy?
Standard residential concrete work — driveways, patios, walkways — typically does not require a licensed engineer stamp for the permit. Foundation work and commercial projects do require engineering drawings. We coordinate with licensed structural engineers for projects that require them.
