Val Verde County Health Department / Risk Management and County Engineering 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 Health Department / Risk Management: 830-774-7569 or 830-774-7570; County Engineer and Floodplain Administrator Carlos Velarde: 830-774-7570 and request the current application route before preparing a final submittal.

The county states that permits issue only after all necessary documentation is provided but publishes no fixed building, floodplain, certificate, or inspection turnaround. Complete OSSF planning materials and an application must be approved or denied within 30 days under 30 TAC Chapter 285; expiration of that period does not create automatic approval.

Apply in person through Health Department / Risk Management with the legal description, proof of ownership, plans, plot design, applicable survey and floodplain delineation; both owner and contractor signatures are required. Staff verifies survey pins, batter boards, and the plot design before issuing an Amistad-area building permit, and a newly constructed or placed residence must be inspected before occupancy. Call 830-774-7569 or 830-774-7570 to coordinate inspections. Contact County Engineer/Floodplain Administrator Carlos Velarde at 830-774-7570 before floodplain development. For an OSSF, submit the completed application, plot design, potable-water and septic locations, site evaluation, system design, and fee; obtain Authorization to Construct and the required inspection before covering or operating the system.

Val Verde County requires building and sign permits within the Amistad Land Use and Zoning Order area. The published process applies the area's land-use/zoning requirements, requires building plans, a scaled plot plan, survey information, ownership documentation, and delineation of any 100-year floodplain, but the county does not publish a specific currently adopted IRC, IBC, electrical, plumbing, mechanical, or fire-code edition for that program. Floodplain development is governed by the county Flood Damage Prevention Order and FEMA FIRM/FIS standards. The county OSSF order applies Texas Health and Safety Code Chapters 341 and 366, Texas Water Code Chapters 7, 26, and 37, and 30 TAC Chapters 30 and 285; new and replacement OSSFs on lots of one acre or less in the Amistad area must be aerobic systems. County subdivision and Model Subdivision Rules also apply to plats. The City of Del Rio has separate municipal permitting jurisdiction. The county expressly limits its building and sign permit requirement to property in the Amistad Land Use and Zoning Order area; outside that area, floodplain, OSSF, subdivision, utility-certificate, and municipal requirements can still apply. A Letter of Non-Applicability process is available for qualifying utility-service situations. Under current OSSF rules, a system serving the only single-family dwelling on at least 10 acres may be permit-exempt after a licensed site evaluation if every component is at least 100 feet from property lines, effluent remains on the tract, and it creates no nuisance or groundwater pollution; listed emergency repairs require written notice within 72 hours instead of an advance permit. No blanket cosmetic-work exemption is published for regulated Amistad or floodplain development.
