Do you need a building permit in Comal County, Texas?

Unincorporated Comal County has no general residential building permit requirement21. County approvals that may apply before construction include septic (OSSF), floodplain development, driveway/right-of-way (PIPROW), utility, Fire Marshal and Camp Bullis Dark Skies lighting permits1. The county Fire Code covers commercial establishments, public buildings and multifamily dwellings with 4 or more units in unincorporated areas10. For cities reaching into Comal County, San Antonio, mainly in Bexar County, and Schertz, mainly in Guadalupe County, administer their own building permits inside city limits1112. Septic permitting remains with Comal County Environmental Health for Comal County properties5.

Who issues building permits and inspections in Comal County?

For an ordinary home in unincorporated Comal County, start with the offices responsible for the specific approvals your project needs1. Comal County Environmental Health handles septic permits, and the Engineer's Office handles floodplain development permits; both list 830-608-2090 and 195 David Jonas Drive, New Braunfels, TX 78132131459. The Road Department handles county right-of-way driveway applications at the same phone and address1516. The Fire Marshal's Permit Division handles covered fire-code construction at 830-643-3748, 145 David Jonas Dr., New Braunfels, TX 781321710. Covered projects need a permit before construction or substantial improvement, including qualifying work exceeding 50% of building value or a change in occupancy classification18. The permittee must arrange sufficient professional inspections and a signed, sealed final inspection request; the Fire Code Official conducts the final occupancy inspection before issuing a Certificate of Compliance19.

Does Comal County have zoning?

Unincorporated Comal County has no county zoning district, minimum dwelling size, lot-coverage or building-height rule; county zoning does not restrict accessory dwellings, RVs, tiny homes, manufactured homes or temporary camping3. New Braunfels administers municipal zoning inside city limits, while its ETJ subdivision review operates through agreements with Comal and Guadalupe Counties20. Bulverde applies district-specific zoning inside its corporate limits21. Cities reaching into Comal County also set zoning: San Antonio and Fair Oaks Ranch, mainly in Bexar County, and Schertz, mainly in Guadalupe County222324. Comal County Environmental Health remains the septic permitting authority for county properties inside cities5. County subdivision rules still require platted individual-OSSF lots of at least 1.0 acre with approved public water or 5.01 acres without, and plats show a 25-foot road-frontage building setback825.

How do septic permits work in Comal County?

Comal County Environmental Health requires approved plans and a septic permit before building, altering, extending or operating an OSSF5. Obtain a site and soil evaluation and authorization to construct before installation; homeowners may sometimes design a conventional system with local assistance, but complex systems and specified sites require professional planning26. Installation requires 3 inspections with at least 24 hours' notice; a failed or unready system triggers a $150 reinspection fee, and a Permit of License to Operate is required before use27. Texas allows a permitting exemption for a single-family dwelling on at least 10 acres only when it is the tract's only dwelling, a qualified evaluator assesses the site, all system components are at least 100 feet from property lines, effluent stays on-site, standards are met, and no nuisance or groundwater pollution results; ask Environmental Health whether local requirements allow the exemption28. Only 2.2% of Comal County land is rated without severe limitations for conventional drain fields, making septic feasibility a priority before purchase29.

Can you live in an RV or tiny home on your land in Comal County?

County zoning does not restrict RV or tiny-home occupancy on unincorporated Comal County land3. Off-grid wastewater still needs an approved OSSF plan and septic permit where public sewer is unavailable, subject to applicable exemptions3031. A home or manufactured home in the unincorporated county's 100-year floodplain needs a floodplain application and compliant plans, with the lowest floor at or above the floodplain elevation32. Owner-installers of industrialized housing for their own use may obtain a $75-per-building state installation permit instead of industrialized-builder registration; that option concerns regulated modular construction, not ordinary site-built homes33. Inside New Braunfels, short-term rentals are prohibited in residential zoning districts and the floodway, and permitted rentals require registration and annual life-safety inspections34.

Building a home in Comal County: what are the steps, in order?

  1. Establish city-limit and ETJ status before choosing the approval route; municipal zoning and subdivision-review arrangements differ from unincorporated county rules420.
  2. Apply for relevant county approvals in person or through the county's online portal, completing and uploading the documents for each permit type35.
  3. Ask the Engineer's Office for a floodplain determination; the application requires a scaled drawing, recorded ownership proof and a $40 fee14936.
  4. Arrange the septic evaluation and approved plans with Environmental Health, then obtain authorization to construct before installing the OSSF1326.
  5. Apply to the Road Department before county right-of-way work: PIPROW costs $25 and requires an on-site meeting and final inspection; concrete driveways also need a pre-pour inspection1516.
  6. For a state-highway driveway, submit TxDOT Form 1058 to the local district office37.
  7. Obtain written Comal Trinity Groundwater Conservation District authorization before drilling or altering a well within the district38.
  8. For covered commercial, public or multifamily construction, secure the Fire Marshal's building permit and arrange required inspections before occupancy1819.

What should you check before buying land in Comal County?

For a divided tract in unincorporated Comal County, verify subdivision approval: the regulations effective June 11, 2026 generally require a plat when dividing land to lay out lots, a subdivision or specified shared-use areas39. Subdivision lots cannot be sold before final Commissioners Court approval and filing with the County Clerk; even plat-exempt subdivisions need 60 continuous feet of frontage on or to existing county roads40. Qualifying agricultural, ranch, wildlife-management or timber divisions may avoid platting only under stated conditions, including no specified shared-use areas; OSSF lot-size requirements remain, and platting applies if the qualifying use ends41. For an existing non-exempt Trinity well within the Comal Trinity Groundwater Conservation District, verify registration; existing-well registration has no fee42. New-well authorization expires if drilling is not completed within 1 year38. Comal County's effective property tax rate is about 1.2%, with a median annual bill around $4,8274344.

Watch-outs

  • Homeowner help with septic design does not waive approved plans, authorization to construct, installation inspections or the license to operate2627.
  • We could not confirm a countywide public-water or sewer connection requirement; ask Comal County Environmental Health and the serving utility before budgeting for an independent system4513.
  • Texas permits some counties to adopt residential building-code standards by resolution; we could not confirm whether Comal County has adopted that option, so ask the Engineer's Office4614.
  • Outdoor lighting in the Camp Bullis Dark Skies Zone may require county approval; the listed application fee is $25147.

  • Minimum lot sizeSpecified

    Platted OSSF lot subdivisions in unincorporated Comal County

    • For subdivisions requiring platting where each lot is not served by a TCEQ-approved public water supply and uses an individual OSSF, each lot must be at least 5.01 acres.
    • The regulations also state that certain plat exemptions must still meet minimum lot-size requirements in the Comal County OSSF Order.

    minimum lot area with TCEQ-approved public water supply and individual OSSF: >= 1 acre · minimum lot area without TCEQ-approved public water supply and with individual OSSF: >= 5.01 acres

    “Subdivisions requiring platting, where each lot within the proposed subdivision will be served by a Texas Commission on Environmental Quality (TCEQ)-approved public water supply and will utilize individual on-site sewage facility methods for sewage disposal, shall provide for individual lots having surface areas of at least 1.0 acre. Subdivisions requiring platting, where each lot within the proposed subdivision will not be served by a TCEQ-approved public water supply and will utilize individual on-site sewage facility methods for wastewater treatment, shall provide for individual lots having surface areas of at least 5.01 acres.”
  • SetbacksSpecified

    Lots shown on subdivision plats in unincorporated Comal County

    • The 25-foot building setback is shown adjacent to all road frontage on subdivision plats.
    • The rule is stated for subdivision plat dimensions and does not establish a general countywide setback for every development context.

    minimum building setback from road frontage: >= 25 feet

    “Dimensions of all lots with a 25' minimum building setback shown adjacent to all road frontage. If shown by note: “Comal County requires a minimum 25’ building set-back line from road frontage.””
