Bastrop County does not issue building permits or certificates of occupancy in unincorporated areas — but it goes further than most Texas counties. It operates a Development Services department that issues development permits covering floodplain, driveway, and OSSF work, and it imposes limited residential code requirements on new single-family houses, duplexes, and certain large additions.
The twist is enforcement. Those residential requirements exist, but the county does not inspect against them. The builder contracts privately with a qualified inspector, typically at foundation stage before concrete placement, at framing and mechanical before wall covering, and at completion. Requirement without county inspection is an unusual middle ground, and it catches builders who read "no building permit" as "no obligations."
Bastrop also carries an environmental constraint almost nowhere else in Texas has: the Lost Pines Habitat Conservation Plan area, covering endangered Houston toad habitat. Development inside it requires participation in the plan for incidental take authorization, and that question appears directly on the county development application.
Covers unincorporated Bastrop County. The City of Bastrop, Elgin, Smithville, and the other incorporated municipalities run their own permitting under their own codes — confirm whether the parcel is inside a city limit before assuming county rules apply.
Three questions decide a Bastrop County project before design starts. Is any part of the property in the FEMA 100-year floodplain? Is it inside the Lost Pines Habitat Conservation Plan area for the Houston toad? Does it comply with subdivision plat requirements or meet an exception? All three appear on the county’s own application, and all three can reshape a site plan after the fact if answered late.
What requires a county permit in Bastrop County?
Bastrop County sits between the two common Texas patterns. It does not issue building permits, but it does run a development permitting program, and it does impose limited residential code requirements without inspecting against them.
The document set for a county development or OSSF application is substantial: proof of ownership, a dimensioned site plan, a survey or plat, a soil evaluation report prepared by a licensed site evaluator or professional engineer, septic plan and specifications with setbacks, copies of other required permits such as a TxDOT driveway permit, and an easement release where construction crosses an easement.
County record required
- County development permit for external development in unincorporated areas
- On-site sewage facility permit, with soil evaluation by a licensed site evaluator or P.E.
- Floodplain authorization where any part of the property is in the FEMA 100-year floodplain
- Driveway permit — county, or TxDOT where access meets a state road
- Lost Pines Habitat Conservation Plan participation inside the Houston toad habitat area
- Subdivision plat compliance, or documentation of an exception
- Easement release where construction extends onto or across an easement
- Water well permit through the Lost Pines Groundwater Conservation District
No county building permit or inspection
- County building permit — not issued
- County certificate of occupancy — not issued
- County-performed construction inspections — inspections are private
- County trade permits for electrical, plumbing, or mechanical work
Bastrop County building department: who handles permitting
Bastrop County Development Services administers development permits, OSSF permitting, floodplain review, and driveway permits from 211 Jackson Street in Bastrop. It is a genuine development office rather than a scattered set of county functions, which makes Bastrop easier to navigate than most rural Texas counties.
Water wells sit outside county authority. The Lost Pines Groundwater Conservation District, created by voters in 2002, issues water well permits and oversees groundwater use across Bastrop and Lee counties.
| Detail | Information |
|---|---|
| Authority | Bastrop County Development Services |
| Office | 211 Jackson Street, Bastrop, TX 78602 |
| Phone | (512) 581-7176 |
| development.services@co.bastrop.tx.us | |
| Building permits | Not issued; development permits issued instead |
| Residential inspections | Private — builder contracts a qualified inspector |
| Habitat review | Lost Pines Habitat Conservation Plan, Houston toad |
| Water wells | Lost Pines Groundwater Conservation District |
Ask Development Services which records a specific parcel triggers before assembling anything. External development in the unincorporated county may require a development permit, floodplain review, driveway permit, and OSSF permit in combination, and the sequence matters more than the individual applications.
Bastrop County permits: record types and what each covers
The permit-type question works differently in a Texas county, and Bastrop is a hybrid. It issues no building permits and no certificates of occupancy, but it does run a development permitting program and it does impose limited residential code requirements — verified by a privately contracted inspector rather than by the county. The records below are what actually exist.
What Bastrop County actually issues
| Record | What triggers it | Who administers it | Notes |
|---|---|---|---|
| OSSF permit to construct | Installing, altering, repairing, or extending an on-site sewage facility where no public sewer is available | Bastrop County Development Services | Required statewide; soil evaluation by a licensed site evaluator is part of the application |
| OSSF license to operate | Issued after the permit to construct requirements are met and the system passes inspection | Bastrop County Development Services | Also triggered on transfer of ownership of an existing system |
| Floodplain development permit | Placing fill, setting a structure, or developing in or near a mapped special flood hazard area | County floodplain administrator | Substantial improvement and substantial damage rules attach to existing structures |
| Subdivision plat | Dividing land in the unincorporated county | Commissioners Court and county engineering | Road, drainage, and access standards apply |
| 911 address assignment | New structures and new access points needing an address | County addressing / emergency management | Usually a prerequisite for utility service |
| Right-of-way and driveway culvert | New or modified access onto a county road | County road and bridge / precinct | Culvert sizing set by drainage conditions |
| Water well registration | Drilling a water well | Lost Pines Groundwater Conservation District | Groundwater districts operate independently of the county |
| Limited residential code compliance | New single-family houses, duplexes, and certain large additions | Owner and builder, verified by a privately contracted inspector | County imposes the requirement but performs no inspections itself |
| Ch. 233 commercial / multifamily | New commercial, public-accessible, or multifamily buildings, and substantial improvements, where the county has adopted the authority | Commissioners Court | Scope is set by county order; confirm adoption before assuming it applies |
County reaches this
- On-site sewage facilities, everywhere in the state
- Floodplain development and substantial improvement
- Subdivision of land and county road access
- Addressing, and fire code where separately adopted
County generally does not
- Issue residential building permits in unincorporated areas
- Conduct residential construction inspections
- Issue a residential certificate of occupancy
- Enforce a residential building code absent a county order adopting one
Solar permits in Bastrop County
In unincorporated Bastrop County there is generally no county building permit for a residential rooftop or ground-mount photovoltaic system, because the county does not regulate residential construction. That is a jurisdictional fact rather than a green light: the electrical work still has to be performed by a TDLR-licensed electrician to code, and the utility still governs interconnection.
Utility interconnection is the real gate. The interconnecting utility — the wires company in deregulated territory, or the electric cooperative serving the parcel in much of rural East Texas — runs its own application, engineering review, and Permission to Operate process, and it is not waived by the absence of a county permit.
Under Tex. Prop. Code §202.010 a property owners' association cannot prohibit a solar energy device outright, and any dedicatory provision that does is void — but the statute preserves the association's right to require prior architectural approval and to impose placement and appearance conditions. Approval cannot be unreasonably withheld.
Inside Bastrop city limits the picture changes completely: the city permits solar like any other municipality. The jurisdiction question is the first question.
Roofing permits in Bastrop County
A residential roof covering replacement in unincorporated Bastrop County generally does not require a county permit, for the same reason: Texas counties have no general authority over residential construction outside city limits.
Two things still apply. If the structure sits in a mapped special flood hazard area, the county floodplain ordinance can reach the work through substantial improvement rules — and cumulative improvement value is what triggers them, so a reroof after other recent work can cross the threshold on its own. And commercial or multifamily buildings can fall under the county's Ch. 233 authority where it has been adopted.
Texas has no statewide product approval system and no central listing to check a roofing product against. Hail is the governing risk across East Texas, and impact-resistant Class 3 and Class 4 shingles carry insurance premium credits from most carriers. Under Tex. Prop. Code §202.011 a property owners' association cannot prohibit wind or hail resistant shingles, or shingles that improve energy efficiency.
Bastrop County sits in Central Texas at roughly 105 to 115 mph ultimate design wind speed under the codes regional cities adopt, well outside any TDI windstorm requirement. Wildfire is the exposure that distinguishes this county — the 2011 Bastrop County Complex Fire burned for weeks, destroyed more than 1,600 homes, and reshaped how insurers and builders treat the Lost Pines. Roof assembly and ember-resistant detailing matter here for reasons the wind map does not capture.
Texas has no statewide building code and no statewide general contractor license. In the unincorporated county the practical compliance surface is the trades — TDLR for electrical and mechanical, the TSBPE for plumbing — plus the county's environmental and floodplain records, rather than a building department.
Bastrop County permit cost and fees
Bastrop County charges no building permit fee because it issues no building permit. Costs attach to the development permit, OSSF permitting and its required soil evaluation, floodplain authorization, driveway permits, and platting — plus the private inspection the residential requirements imply.
Budget the private inspector explicitly. Because the county imposes residential requirements but does not inspect, that cost sits with the builder and is frequently omitted from an early estimate, then discovered when a lender or insurer asks for documentation.
| Fee component | How it works |
|---|---|
| Building permit | None — not issued by the county |
| Development permit | County fee per the application fee schedule; non-refundable |
| OSSF permit | County fee plus licensed soil evaluation and septic design |
| Private inspections | Contracted by the builder; not a county charge but a real cost |
| Floodplain authorization | Survey delineating flood zones, floodway, and FIRM panel |
| Water well | Lost Pines Groundwater Conservation District fees, separate from the county |

Bastrop County trade permits
There is no county trade permit program in unincorporated Bastrop County. Electrical, plumbing, and mechanical work is not permitted or inspected by the county, though the OSSF connection is permitted and the limited residential requirements reach mechanical systems at the framing stage of the private inspection sequence.
Electrical
No county permit or inspection. A TDLR-licensed electrician remains the standard, and the private inspection is the only verification that will exist.
Plumbing
No county permit for interior plumbing, but the septic system is permitted through Development Services with a licensed soil evaluation behind it.
Mechanical / HVAC
No county permit. Mechanical systems are covered at the framing-stage private inspection on qualifying residential work.
Inside a city limit
The City of Bastrop, Elgin, and Smithville permit and inspect trades normally. Jurisdiction determines everything.
Bastrop County permit application: how to apply step by step
Check whether the property sits inside the City of Bastrop, Elgin, or Smithville. This changes the process entirely.
Is any part of the property in the FEMA 100-year floodplain? Is it inside the Lost Pines Habitat Conservation Plan area? Does it comply with plat requirements or meet an exception? These drive everything downstream.
Where floodplain is present, the survey must delineate flood zones, floodway, proposed footprints, drainage easements, and the correct FIRM panel. The soil evaluation must come from a licensed site evaluator or professional engineer.
Proof of ownership, dimensioned site plan, survey or plat, septic plan and specifications, location map, copies of other required permits including TxDOT driveway where applicable, and easement releases.
For new single-family, duplex, and qualifying large additions, contract a qualified inspector before construction — the sequence runs foundation before concrete, framing and mechanical before wall covering, and completion.
Complete the septic installation and inspection, put the maintenance contract in place for secondary treatment systems, and record any required affidavit with the county clerk.
Inspections in Bastrop County
Bastrop County does not perform construction inspections. For residential work covered by the county’s limited requirements, inspections are private — the builder contracts a qualified inspector, and the county neither schedules nor performs them.
The typical sequence for qualifying residential construction is foundation stage before concrete placement, framing and mechanical systems before drywall or similar wall covering, and completion of construction. For remodeling, inspections are performed as the scope warrants.
OSSF is inspected as part of the county permitting process, and secondary treatment systems require a continuing maintenance contract. Keep the private inspection reports — they are the only construction record that will exist.

Frequently asked questions
Who issues building permits in Bastrop County?
No one, for general residential construction in unincorporated areas — Bastrop County has no adopted residential building code and no building inspection program. The records that do apply are administered separately: on-site sewage through Bastrop County Development Services, floodplain development through the county floodplain administrator, plats through Commissioners Court, and road access through the precincts. Inside Bastrop city limits, the city permits normally.
How do I get a permit in Bastrop County?
Start by confirming the parcel is actually unincorporated, because that single question changes everything and a mailing address will not answer it. If it is, work the records the county does issue rather than looking for a building permit: septic first, since it constrains siting and carries the longest lead time, then floodplain, plat, addressing, and road access as the project triggers them.
What codes apply in Bastrop County?
Texas has no statewide building code, and Bastrop County has not adopted one for unincorporated areas, so no building code is enforced there. State rules still govern on-site sewage facilities, and the county’s floodplain ordinance governs development in mapped flood hazard areas. Trade work remains subject to state licensing through TDLR and the TSBPE. Inside city limits, the municipality’s adopted codes apply in full.
Does Bastrop County issue building permits?
No. Bastrop County does not issue building permits or certificates of occupancy in unincorporated areas. It does operate Development Services and issue development permits covering floodplain, driveway, and OSSF work, and it imposes limited building code requirements on new single-family houses, duplexes, and certain large additions — but it does not perform inspections against them. That combination is unusual and is the thing most often misunderstood about this county.
What is the Lost Pines Habitat Conservation Plan?
It is an endangered species program covering Houston toad habitat in Bastrop County, and it appears as a direct question on the county development application: whether the property is inside the plan area, and if so whether the applicant agrees to participate for incidental take authorization. Development inside the habitat area carries obligations that have nothing to do with building code and everything to do with federal species protection. Determine the answer before designing a site plan.
Who inspects construction in unincorporated Bastrop County?
A private inspector the builder contracts, not the county. Bastrop imposes limited residential code requirements on new single-family houses, duplexes, and certain large additions, but performs no inspections itself. The typical sequence is foundation before concrete placement, framing and mechanical before wall covering, and completion. Those private reports are the only construction record that will exist for a future lender, insurer, or buyer — keep them.
Do I need a permit to install solar panels in Bastrop County?
Yes. Photovoltaic installations in Bastrop County are permitted under a dedicated solar record type reviewed on both a structural and an electrical track. Solar thermal — passive water and pool heating — is a separate record. Under Tex. Prop. Code §202.010 a homeowners' association cannot ban a solar energy device outright, but it may still require prior architectural approval and impose reasonable placement conditions, so run the HOA submittal alongside the permit. Since September 1, 2025, Tex. Local Gov't Code §247.0025 (SB 1202) also permits third-party plan review and inspection of home backup power installations — generators and energy storage for one- and two-family dwellings at 600 volts or less — in place of jurisdiction review. Utility interconnection and Permission to Operate still run in parallel.
Does a roof replacement require a permit in Bastrop County?
Yes, in most cases. A roof covering replacement requires a permit in most Texas municipalities including Bastrop County, though minor repairs can fall below the local threshold. Texas has no statewide product approval system and no central product listing, so compliance runs against the locally adopted code edition and its local amendments. Hail rather than wind is the governing risk inland, and Tex. Prop. Code §202.011 bars an HOA from prohibiting wind or hail resistant shingles.
What is the difference between a residential and a commercial permit in Bastrop County?
In a Texas county it is the difference between no county jurisdiction and possible county jurisdiction. Residential construction in unincorporated Bastrop County is largely outside county authority. New commercial, public-accessible, and multifamily buildings, plus substantial improvements, are the categories Local Government Code ch. 233 lets a county reach — but only where Commissioners Court has adopted that authority, so confirm it rather than assuming.
Do trade permits need to be pulled separately in Bastrop County?
Not in unincorporated Bastrop County — there is no county trade permit program and no county trade inspection. Electrical, plumbing, and mechanical work should still be performed by contractors licensed through TDLR and the TSBPE, and the septic connection is permitted and inspected separately. Inside city limits, trade permits work normally.
What happens if I file under the wrong permit type in Bastrop County?
Because Bastrop County does not run a building permit program, the more common failure is filing nothing at all — assuming that no building permit means no requirements, and missing the septic, floodplain, plat, or addressing record the project actually triggered. Those are enforced, and unwinding them after construction is materially harder than filing them in order.
Can I apply for all Bastrop County permit types online?
Partly. Bastrop County publishes its development and OSSF applications online as PDF packets and Development Services can be reached by phone or email, which is better than most rural Texas counties offer. It is not a municipal-style portal though: expect document assembly, a non-refundable fee paid by check or money order, and direct correspondence with staff rather than portal status tracking.
