Digital permit application gateway
Start with the issuing authority’s own submission lane. A complete application package, accurate valuation, and accessible inspection path are the fastest route through statutory plan review.
Recommended first click
Use the official digital gateway to submit plans, monitor review comments, pay required charges, and request inspections when the permit is issued. If the link is unavailable, use the agency website or phone number on the administrative profile to confirm the current lane.
Typical review lane
N/A; Gillespie County’s reviewed OSSF and floodplain materials do not publish a standard review timeline.
Treat this as a planning signal, not a guaranteed approval date. Completeness, corrections, resubmittals, and agency workload control the actual clock.
Verify the parcel is inside this agency’s service area and note whether a city, state, fire marshal, septic authority, or utility district also has approval authority.
Prepare legible plans, site information, project valuation, ownership authorization, contractor information, and any energy, floodplain, zoning, or utility documentation the issuing office requires.
Keep the permit number, approved plan set, correction comments, fee receipts, and inspection results together. Those records establish the compliance trail for the next trade.
Application documents
Before submission, call Gillespie County OSSF/Sanitation: 830-997-8191; Engineering/Floodplain/ROW: 830-307-6196 or 830-307-6048 if the project involves a change of occupancy, structural alteration, accessory structure, demolition, or work near a regulated environmental feature.
Source trail
Use these direct agency or licensing links to confirm current instructions before you file, pay, or schedule work. External pages control if their information differs from this directory.
Project questions
Gillespie County Sanitation (OSSF) Department / Engineering Department 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 Gillespie County OSSF/Sanitation: 830-997-8191; Engineering/Floodplain/ROW: 830-307-6196 or 830-307-6048 and request the current application route before preparing a final submittal.
N/A; Gillespie County’s reviewed OSSF and floodplain materials do not publish a standard review timeline.
Obtain and complete the OSSF application, including property/legal description, site information, installer details, and planning materials. Since August 1, 2025, obtain a Development Permit Determination and Site Plan with Narrative from the County Engineer before submitting the septic application; the OSSF application is incomplete without the signed determination. For floodplain development, email the completed development permit and supporting documents to floodplain@gillespiecounty.org or submit hard copy to the courthouse. The OSSF permit is valid for one year from purchase; after construction, the county issues Authorization to Construct/Notice of Approval through its inspection process and requires applicable aerobic affidavits and maintenance contracts.
Gillespie County’s current program requires OSSF planning materials, application, permit, and inspection for construction, alteration, extension, or repair of any OSSF, including systems on tracts of 10 acres or more. OSSF work follows Texas Health and Safety Code Chapter 366 and 30 TAC Chapter 285, plus the Gillespie County OSSF Order effective October 14, 2025. Floodplain work follows the county Flood Damage Prevention Ordinance effective July 28, 2025; no general countywide ICC building-code edition was verified. The county’s 2025 OSSF order requires permitting and inspection for all OSSF construction, alterations, extensions, and repairs regardless of tract size, so the ordinary 10-acre state exemption is not a county exemption. Aerobic systems and other systems identified by the county require maintenance by a TCEQ-registered technician or licensed maintenance provider rather than the homeowner. The reviewed materials do not publish a broad cosmetic building-work exemption list.
What makes an application complete
Before you click submit, make sure the drawings agree with the site plan, project description, valuation, ownership authorization, and contractor information. If the work changes structure, occupancy, drainage, fire protection, energy performance, or utility demand, describe that scope plainly. Ambiguous narratives create correction cycles and delay the field schedule.
Save the confirmation number, payment receipt, uploaded plan set, and every correction comment. Those records are the backbone of a defensible compliance file when multiple trades or agencies share responsibility.
Submission quality check
Site: address, parcel, access, setbacks, and existing conditions are consistent.
Scope: structural, mechanical, plumbing, electrical, fire, and energy work is identified.
Closeout: inspection contacts and the final approval path are understood before work begins.
