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
Allow 7-10 business days for non-floodplain determinations; floodplain development, septic permits, and commercial projects may take longer. A floodplain development permit expires 180 days after issuance and may receive one additional 180-day extension for good cause if requested before expiration; no further extension is allowed.
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 325-247-2039; fax 325-247-3785 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
Llano County Development Services and 9-1-1 Addressing is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact 325-247-2039; fax 325-247-3785.
Allow 7-10 business days for non-floodplain determinations; floodplain development, septic permits, and commercial projects may take longer. A floodplain development permit expires 180 days after issuance and may receive one additional 180-day extension for good cause if requested before expiration; no further extension is allowed.
Apply through iWorQ and upload the site plan, scope, ownership and authorization documents, 9-1-1/address details, septic information, and any required elevation certificate, engineered plans, no-rise certificate, or floodproofing documents. Call 325-247-2039 to coordinate inspections. New or substantially improved development below BFE requires preliminary and final floodplain inspections; passing final inspection and submission of the final elevation certificate and owner confirmation are prerequisites to a Certificate of Compliance. OSSF construction must await authorization and every system is county-inspected before approval to operate.
Llano County reviews development in unincorporated areas under its Development Services orders, 2025 Subdivision Regulations, 2021 Flood Damage Prevention Order/NFIP standards, 9-1-1 addressing order, road-cut rules, and OSSF order. Any development in a special flood hazard area requires a floodplain development permit; floodplain construction must meet elevation, anchoring, flood-opening, no-rise, and engineering requirements. The county adopts 30 TAC Chapters 30 and 285 for OSSF and permits and inspects every on-site system regardless of tract size. No general countywide ICC structural building-code edition was found. All proposed structures or development projects enter the county development-review process, although the additional floodplain permit applies when development is in a special flood hazard area. Llano County expressly permits and inspects every OSSF regardless of tract size, so the state 10-acre permit exception does not apply. No cosmetic-work exemption list is published; the application identifies clearing, fill, grading, excavation, docks, retaining walls, fences, drainage work, roof replacement, demolition/rebuild, and other development for county review.
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.
