Codes, exemptions & field inspections
This guide translates the available agency record into a preconstruction checklist for structural scope, minor work, and inspection release. The adopted code and the issuing official control when a field condition is disputed.
Regulatory framework
Medina County Flood Damage Prevention Court Order adopted in 2020, with FEMA flood maps effective May 15, 2020; Medina County Rules for On-Site Sewage Facilities under Texas Health and Safety Code Chapter 366 and 30 TAC Chapter 285; 2024 Medina County Subdivision Rules and Regulations. The county does not publish a generally enforced structural building-code edition for unincorporated construction.
Inspection lane
For septic inspections, call Environmental Health at 830-741-6195 at least one day in advance; inspections are conducted Monday, Wednesday, and Friday. Call between 8:00 and 8:30 AM on the inspection day to receive the assigned time. The floodplain application includes a final-inspection checklist and requires closure by the Floodplain Administrator after compliance and any required elevation certificate are documented.
Minor-work playbook
No minor-work exemption applies to regulated floodplain development: any man-made change to improved or unimproved real estate—including structures, fill, grading, paving, excavation, drilling, mining, dredging, or storage—requires a floodplain permit. All OSSF systems require a septic permit regardless of tract size. Certain land divisions may be exempt from plat approval, but those exemptions do not waive OSSF or floodplain compliance.
Field rule
A permit exemption generally addresses one narrow construction trigger. It does not automatically waive zoning, land-use, floodplain, shoreline, fire, energy, electrical, utility, septic, or right-of-way requirements. Obtain written confirmation when the project involves a new structure, structural alteration, change in occupancy, or concealed work.
Inspection pipeline
Request with lead time
For septic inspections, call Environmental Health at 830-741-6195 at least one day in advance; inspections are conducted Monday, Wednesday, and Friday. Call between 8:00 and 8:30 AM on the inspection day to receive the assigned time. The floodplain application includes a final-inspection checklist and requires closure by the Floodplain Administrator after compliance and any required elevation certificate are documented.
Preserve access
Do not cover framing, reinforcement, wiring, piping, damp-proofing, or life-safety work until the required inspection has been completed and documented.
Close the record
Retain the approved plans, inspection approvals, correction responses, and final certificate or occupancy release with the property file.
Contractor verification
Use the state licensing system to verify active registration, trade credentials, bond status, and liability coverage where available. Match the legal business name to the proposal and permit application.
Planning reference
A building permit is only one part of statutory compliance. Check the local zoning, ordinance, map, or land-use reference before finalizing setbacks, height, lot coverage, access, drainage, or accessory structure placement.

Project questions
Medina County Environmental Health Group and Floodplain Administrator is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
No verified online portal was located in the reviewed public materials. Contact Environmental Health/Floodplain: 830-741-6195; 911 Addressing: 830-741-8997; Fire Marshal: 830-455-0129 and request the current application route before preparing a final submittal.
N/A. Published OSSF instructions state that incomplete paperwork delays review and that permit fees are nonrefundable and valid for one year, but no standard approval timeline is stated.

Field sequencing matters
Code compliance is not only a plan-review exercise. Footings, reinforcement, framing, fireblocking, wiring, piping, insulation, weather protection, and life-safety systems each have points where the work must remain accessible. Build the inspection calendar into the trade schedule instead of treating it as a final administrative step.
When a project qualifies for a narrow minor-work exemption, keep a written explanation of why it qualifies and confirm that related zoning, utility, fire, energy, or environmental rules do not create a separate approval requirement.
Closeout file
Keep the approved plan set, inspection approvals, correction responses, contractor license verification, final certificate, and any occupancy release together. A clean record protects the owner, builder, lender, insurer, and future buyer.
