Comal County does not issue general building permits, but it is unusually clear about what it does require. When building in the unincorporated parts of the county there are typically four county permits to obtain during construction: the on-site sewage facility permit, the floodplain development permit, a private improvement within the public right-of-way permit, and in some cases a Fire Marshal permit.
That four-permit framework is genuinely useful, because it replaces the vague "what does a Texas county actually require" question with a checklist. The OSSF permit is submitted with a design from a registered engineer or sanitarian who certifies the design complies with state regulations, and is usually processed within 10 business days depending on complexity and completeness.
Two deadlines worth noting. Construction of the OSSF must commence within one year of permit issuance. And the county states plainly that constructing improvements applicable to the County Orders without the necessary permitting is typically a criminal offense — stronger language than most Texas counties use.
Covers unincorporated Comal County. New Braunfels, Bulverde, Garden Ridge, Schertz, Selma, and Fair Oaks Ranch permit their own territory — confirm whether the parcel is inside a city limit before assuming county rules apply.
Floodplain determination runs through the OSSF permit. If the County Engineer’s Office determines the development associated with an OSSF permit is within the regulatory floodplain, a floodplain development permit follows. Where a proposed development is not associated with an OSSF permit, the office provides a floodplain development determination through a separate Floodplain Development Permit Application. Either way, the determination comes from the County Engineer.
What requires a county permit in Comal County?
The question in unincorporated Comal County is not which building permit you need. It is which of the four county permits your project triggers, and whether the parcel is genuinely outside every city limit in a fast-growing corridor between San Antonio and Austin.
The county is explicit that these permits are the county’s own requirements, and that property owners need to be aware there may be other requirements from property owners associations, municipalities, utility companies, and the state and federal governments. On Hill Country land over the Edwards Aquifer, that last category is not theoretical.
County permit required
- On-site sewage facility permit — with a design from a registered engineer or sanitarian
- Floodplain development permit where the development is in the regulatory floodplain
- Private improvement within the public right-of-way (PIPROW) — driveways, landscaping
- Fire Marshal permit for certain construction under the Comal County Fire Code
- Compliance with the Comal County Flood Damage Prevention Order where applicable
- Subdivision plat when land is divided
Not a county building permit
- County building permit — not issued for general construction
- County building code compliance — none adopted
- County trade permits for electrical, plumbing, or mechanical
- County certificate of occupancy
Comal County building department: who handles permitting
The Comal County Engineer’s Office administers floodplain determinations and the right-of-way permit, and coordinates with Environmental Health on OSSF permitting. The Fire Marshal handles the fourth permit under the county fire code.
Comal sits between San Antonio and Austin along the I-35 corridor, over the Edwards Aquifer recharge and contributing zones. Aquifer protection requirements administered by the Edwards Aquifer Authority run alongside county permitting and can add substantial time on a site with significant disturbance.
| Detail | Information |
|---|---|
| Authority | Comal County Engineer’s Office |
| The four permits | OSSF, floodplain development, PIPROW right-of-way, and Fire Marshal |
| OSSF design | From a registered engineer or sanitarian certifying compliance with state regulations |
| OSSF processing | Usually within 10 business days, depending on complexity and completeness |
| OSSF construction deadline | Must commence within one year of permit issuance |
| Floodplain | County participates in the FEMA program; Flood Damage Prevention Order applies |
| Enforcement | Unpermitted work applicable to County Orders is typically a criminal offense |
| Inside city limits | New Braunfels, Bulverde, Garden Ridge, Schertz, Selma, Fair Oaks Ranch |
The county publishes its permit types with dropdowns showing the related information and documents needed for each. Work through those before assembling anything — the four-permit framework is only simple if you know which of the four your project actually opens.
Comal County permits: record types and what each covers
The permit-type question has an unusually clean answer in Comal County. There is no county building permit, but when building in the unincorporated parts of the county there are typically four county permits to obtain during construction — on-site sewage, floodplain development, private improvement within the public right-of-way, and in some cases a Fire Marshal permit. The records below are those four plus the platting and outside requirements that surround them.
What Comal 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 | Comal County Environmental Health | 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 | Comal County Environmental Health | 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 | Edwards Aquifer Authority and the Trinity Glen Rose GCD | Groundwater districts operate independently of the county |
| PIPROW permit | Private improvement within the public right-of-way — driveway installation or modification, landscaping | County Engineer’s Office | One of the four standard county permits |
| Fire Marshal permit | Certain building construction or improvements under the Comal County Fire Code | Comal County Fire Marshal | The fourth permit; applies to specific construction types |
| 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 Comal County
In unincorporated Comal 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 New Braunfels city limits the picture changes completely: the city permits solar like any other municipality. The jurisdiction question is the first question.
Roofing permits in Comal County
A residential roof covering replacement in unincorporated Comal 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.
Comal County sits in the Hill Country along the I-35 corridor at roughly 105 to 115 mph ultimate design wind speed under the codes regional cities adopt, far from the designated catastrophe area and outside any TDI windstorm requirement. Hail governs. The overlay to watch here is the Edwards Aquifer recharge zone, which brings water quality obligations to site work that have nothing to do with the roof.
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.
Comal County permit cost and fees
Comal County charges no building permit fee because it issues no building permit. Costs attach to the four county permits, the engineered OSSF design behind the septic permit, and any Edwards Aquifer protection requirements that apply to the site.
The OSSF design is a required professional cost, not an optional one — the permit application must be accompanied by a design from a registered engineer or sanitarian who certifies compliance with state regulations. On Hill Country soils over limestone, that design frequently specifies an aerobic system with continuing maintenance obligations.
| Fee component | How it works |
|---|---|
| Building permit | None — not issued by the county |
| OSSF permit | County fee plus an engineered or sanitarian-prepared design |
| Floodplain development permit | County fee; Flood Damage Prevention Order compliance where in the floodplain |
| PIPROW permit | Driveway installation, modification, or other right-of-way work |
| Fire Marshal permit | For certain construction under the county fire code |
| Edwards Aquifer requirements | Separate agency; can add substantial time on disturbed sites |

Comal County trade permits
There is no county trade permit program in unincorporated Comal County. Electrical, plumbing, and mechanical work is neither permitted nor inspected by the county. The on-site sewage facility is the exception, and the Fire Marshal permit reaches certain construction types.
Electrical
No county permit or inspection. A TDLR-licensed electrician remains the standard, and TDLR retains enforcement authority in unincorporated areas.
Plumbing
No county permit for interior plumbing. The septic system is permitted with an engineered or sanitarian-prepared design.
Mechanical / HVAC
No county permit or inspection. TDLR licensure applies to the contractor regardless of whether a permit exists.
Fire
The Comal County Fire Marshal permits certain building construction or improvements under the county fire code — the fourth of the four county permits.
Comal County permit application: how to apply step by step
Check against New Braunfels, Bulverde, Garden Ridge, Schertz, Selma, and Fair Oaks Ranch. The I-35 corridor has grown fast and city limits have moved.
A registered engineer or sanitarian prepares the design and certifies compliance with state regulations. This is required, not optional.
Usually processed within 10 business days depending on complexity and completeness. Construction must commence within one year of issuance.
The County Engineer determines whether development is in the regulatory floodplain — through the OSSF permit where associated, or through a separate Floodplain Development Permit Application where not.
A PIPROW permit covers driveway installation or modification and other right-of-way work. Confirm whether the Fire Marshal permit applies to your construction type.
Edwards Aquifer protection, POA rules, municipal ETJ requirements, utility companies, and state and federal requirements all sit outside the county permits.
Inspections in Comal County
Comal County does not perform general construction inspections in unincorporated areas. There is no foundation, framing, rough-in, or final building inspection, and no county certificate of occupancy.
On-site sewage facilities are inspected as part of the permitting process, and aerobic systems carry continuing maintenance obligations under state rules. Fire Marshal permits carry their own requirements for the construction types they reach.
Private third-party inspection is worth considering on a new build. In a county that performs no building inspection, it is the only independent construction record a lender, insurer, or future buyer will have.

Frequently asked questions
Who issues building permits in Comal County?
No one, for general residential construction in unincorporated areas — Comal County has no adopted residential building code and no building inspection program. The records that do apply are administered separately: on-site sewage through Comal County Environmental Health, floodplain development through the county floodplain administrator, plats through Commissioners Court, and road access through the precincts. Inside New Braunfels city limits, the city permits normally.
How do I get a permit in Comal 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 Comal County?
Texas has no statewide building code, and Comal 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.
What permits does Comal County require for a new home?
Typically four. The on-site sewage facility permit, submitted with a design from a registered engineer or sanitarian certifying compliance with state regulations and usually processed within 10 business days. The floodplain development permit, where the County Engineer determines the development is in the regulatory floodplain. A private improvement within the public right-of-way permit for driveway installation or modification. And in some cases a Fire Marshal permit for certain construction under the county fire code.
How long is a Comal County septic permit valid?
Construction of the on-site sewage facility must commence within one year of the permit issuance. That is a real deadline on a project where design and site work can drift, and it is worth tracking from the issue date rather than assuming the permit sits open indefinitely. Note also that the county characterises constructing improvements applicable to the County Orders without the necessary permitting as typically a criminal offense.
What about property inside New Braunfels or Bulverde?
Then the county guidance does not apply. New Braunfels, Bulverde, Garden Ridge, Schertz, Selma, and Fair Oaks Ranch each permit and inspect construction inside their limits as normal municipal building departments. Comal County’s four permits cover unincorporated territory. Because the I-35 corridor between San Antonio and Austin has grown quickly and city limits and ETJs have expanded with it, confirm the parcel against current boundaries rather than relying on a mailing address.
Do I need a permit to install solar panels in Comal County?
Yes. Photovoltaic installations in Comal 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 Comal County?
Yes, in most cases. A roof covering replacement requires a permit in most Texas municipalities including Comal 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 Comal County?
In a Texas county it is the difference between no county jurisdiction and possible county jurisdiction. Residential construction in unincorporated Comal 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 Comal County?
Not in unincorporated Comal 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 Comal County?
Because Comal 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 Comal County permit types online?
Partly. Comal County publishes its permit types online with dropdowns describing the related information and documents needed for each, and OSSF and floodplain applications and checklists are available on the Environmental Health and Floodplain pages. It is a document-driven process administered through the County Engineer’s Office rather than a municipal-style portal with status tracking and inspection scheduling.
