Bexar County Concrete Permit Guide: What Timberwood Park Homeowners Need to Know
Bexar County’s concrete permit process trips up homeowners every year — not because it’s complicated, but because no competitor publishes a clear guide. This post covers exactly what you need to know before starting any driveway, sidewalk, or major concrete project in Timberwood Park.
In this post, we’ll cover the Bexar County driveway permit requirements, the $35 fee structure, driveway specifications, impervious cover rules, and the Timberwood Park POA approval process that applies before you even get to the county.

Timberwood Park is in unincorporated Bexar County — not the City of San Antonio. This distinction matters: you’re dealing with Bexar County Public Works (Development Services Section, 1948 Probandt St, San Antonio TX 78214), not city building services. The rules and fees differ.
Additionally, Timberwood Park has its own Timberwood Park Owners Association (TPOA) with design guidelines. For most exterior improvements, you’ll need TPOA design review approval before pulling a county permit. Skipping that step can lead to permit revocation and mandatory removal of completed work.
Bexar County Driveway Permit Requirements
What Triggers a Permit?
Any driveway or entrance that involves work in the county right-of-way requires a permit. This includes:
- New driveways from the road to your property
- Replacing or widening an existing driveway approach
- New curb cuts
- Sidewalk connections at the street
Patios and driveways entirely on private property typically don’t require a county permit — but may still need TPOA approval.
The Fee
Bexar County’s driveway/entrance permit fee is a flat $35 per driveway or entrance. The permit application requires a sketch or drawing showing the proposed work in the right-of-way. Work is inspected upon completion.
Driveway Specifications
Bexar County has specific technical requirements for driveways:
- Minimum 4” flexible base (cement treated or asphaltic concrete base acceptable; recycled concrete is NOT accepted as subbase)
- Reinforcement: #3 rebar 18” on center both ways, OR 6”×6” welded wire flat sheets with 8” minimum overlap
- Maximum width: 20 feet for a two-car garage approach; 28 feet for larger garages
These specifications explain why cheap bids often miss — the sub-base and reinforcement requirements add real cost that can’t be avoided on county-inspected work.
Impervious Cover Rules
Bexar County limits the percentage of a lot that can be covered with impervious surfaces (concrete, asphalt, roofing). If your project exceeds the applicable threshold, you’ll need a permit plus a one-time payment into the Storm Water Mitigation Fund — a fee based on the additional pavement area added.
For large Timberwood Park lots (typically ½ acre or more), this threshold is usually not triggered by a single driveway. However, cumulative additions — a driveway plus a patio plus a pool deck — can push over the limit. Ask your contractor to calculate impervious cover before you finalize the project scope.
Request Contractor Contact — Discuss Your ProjectTPOA Design Review for Timberwood Park Projects
The Timberwood Park Owners Association has design standards that apply to exterior improvements on all residential lots. Before starting concrete work visible from the street or common areas, most projects require TPOA design review. The process typically involves:
- Submitting a design application to the TPOA
- Providing a site plan and material description
- Awaiting written approval (typically 2–4 weeks)
- Then proceeding with county permitting
We can advise on what documentation the TPOA typically requires based on project type.
Contractor Licensing in the San Antonio Area
For context: the City of San Antonio requires contractor registration for residential work within city limits ($150 for 2 years for non-structural work, $170 for structural work). For Timberwood Park projects in unincorporated Bexar County, state licensing requirements apply — contractors must carry liability insurance and workers’ compensation.
Frequently Asked Questions
Do I need a permit for a concrete patio in Timberwood Park?
Patios entirely on private property generally don’t require a Bexar County permit. However, TPOA design review may apply. If the patio drains toward the street or affects county-maintained roads or easements, check with Public Works before starting.
How long does the Bexar County permit process take?
For a simple driveway permit with a complete application and sketch, approval typically takes 5–10 business days. Factor in 2–4 weeks for TPOA review if your project requires design approval.
Can my contractor handle the permit?
Yes. Licensed contractors routinely pull permits on behalf of homeowners in Bexar County. Confirm this is included in your contract — some low-bid contractors leave permit responsibility to the homeowner.
Discuss site conditions, scope, permits, and scheduling directly with an independent contractor. This website provides project information and referral requests; it does not perform the work.
