How are inspections scheduled?
For OSSF inspection scheduling, contact Neiland Dean at 361-772-4296. A TCEQ-licensed installer must submit the application packet by appointment, including the soil/site evaluation, scaled design and specifications, deed, map, maintenance documents, and fee. Do not begin construction until the Approval to Construct is received; a Notice of Approval to Operate follows a successful inspection. For floodplain determinations and development permits, submit the county form and $20 residential/commercial fee to Nailene Ruppert at 109 N. LaGrange Street, Hallettsville, telephone 361-798-2301. No public online scheduler was found.
Which codes and exemptions should I review?
Lavaca County requires a development/floodplain determination before construction in unincorporated areas and a floodplain development permit for projects in a Special Flood Hazard Area under its Flood Damage Prevention Ordinance, NFIP standards in 44 CFR, the current Lavaca County FIS/FIRM and revisions, and flood-resistant construction requirements. The county is the OSSF authority under its local order, Texas Health and Safety Code Chapter 366, Texas Water Code, and 30 TAC Chapter 285; all parcels need a permit to install, replace, or repair an OSSF, and applications must be made through a TCEQ-licensed professional installer. No general county structural-building permit program or adopted county ICC code edition was found outside the floodplain context. No cosmetic structural-work exemption list is published. Every proposed development must first receive a county floodplain determination; projects determined outside a Special Flood Hazard Area need no further floodplain documentation, although OSSF and other rules still apply. Lavaca County requires an OSSF permit on every parcel for installation, replacement, or repair, so applicants should not rely on the state 10-acre exception. Homeowners may not install or maintain systems themselves where maintenance is required.
