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
For an approved OSSF application, Authorization to Construct is issued within 30 days; the authorization is valid one year. After an approved installation inspection, Notice of Approval/license to operate is issued within seven days. Commercial and RV-park septic applications also require TCEQ approval and the county warns this may cause substantial delay.
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.

Email or mail the completed floodplain application to Hill County 911 Addressing at 218 North Waco Street and pay the $100 fee; after the permit and payment are received, staff takes a GPS point and returns the assigned address. For floodplain construction, furnish the required elevation certificate within 10 business days after completing the foundation. Effective January 1, 2026, Development Services coordinates OSSF inspections: the installer must request inspection at least five business days before the desired date through the OSSF Designated Representative, and the excavation/installation must remain open until approved.
Hill County administers its Flood Damage Prevention Order, 2025 Subdivision Rules effective March 4, 2025, culvert policy, and local OSSF program under Texas Health and Safety Code Chapter 366 and 30 TAC Chapter 285. The June 2026 Major Industrial Development Review Policy adds independent technical review for large industrial projects only when an applicant requests a discretionary county agreement or action; it does not replace statutory septic, floodplain, road, drainage, or culvert duties. The official county materials reviewed do not publish a general countywide ICC building-code edition. The Flood Plain Development Permit form classifies a project determined to be outside the 100-year floodplain as exempt from the county Flood Damage Prevention Order; the county still uses the form to document that determination and assess applicable 911/addressing needs. No county-specific list of cosmetic or minor general-construction exemptions was published. State OSSF exceptions remain limited to qualifying 10-acre single-family systems, qualifying grandfathered systems, and defined emergency repairs reported in writing within 72 hours.
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.
