How should I begin an application?
No verified online portal was located in the reviewed public materials.

How long might review take?
No county average floodplain, zoning, septic, or inspection turnaround is published. Texas OSSF rules require approval or written denial of a complete septic application and planning materials within 30 days. The flood ordinance's definition of start of construction requires actual permanent work to begin within 180 days after the applicable permit date, but the county does not publish a separate average review time.
How are inspections scheduled?
For mapped floodplain development, contact the Projects Office and Floodplain Administrator at 956-765-9939 before locating, altering, or changing the use of any structure or land; professional elevation or floodproofing certifications may be required. For septic work, contact the Environmental Department at 956-765-6201; the department inspects septic tanks for compliance with state regulations and handles health and nuisance complaints. No online inspection scheduler is published.
Which codes and exemptions should I review?
Zapata County's official 2025-2026 appraisal plan expressly states that the county does not issue building permits, and no adopted IRC, IBC, residential electrical, plumbing, or mechanical code is published. Separate county controls remain: the June 11, 2012 Flood Damage Prevention Ordinance requires a development permit in Special Flood Hazard Areas shown on the July 17, 2012 FIRM/FHBM and requires residential lowest floors at or above base-flood elevation; nonresidential construction must be elevated or professionally designed and certified as floodproof. The county also enforces the December 22, 2009 Zapata County and Falcon Lake Area Zoning Regulations in the statutorily authorized unincorporated area near Falcon Lake, the Rio Grande, tributaries, and arroyos, plus OSSF compliance under Texas Health and Safety Code Chapter 366 and 30 TAC Chapter 285. Because Zapata County does not issue a general building permit, it publishes no cosmetic or minor structural-work exemption list. That absence does not exempt development from the county floodplain ordinance, the applicable Falcon Lake/Rio Grande zoning regulations, OSSF requirements, county sewer or right-of-way rules, deed restrictions, or other state and federal approvals. State OSSF rules may conditionally exempt a qualifying single-family residence on an undivided tract of at least 10 acres when all site-evaluation, separation, ownership, disposal, and nuisance conditions are met; listed emergency repairs must be reported within 72 hours. Confirm all septic exceptions with Environmental Health.
