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
Initial Development Services administrative review may take several business days; a complete overall review time is not published. Fire Marshal projects needing review within 10 business days, projects of at least 10,000 combined square feet, high-hazard occupancies, hazardous-material/aerosol storage, or rack/high-piled storage require approved outside third-party plan review plus county fees.
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 Development Services: 512-393-2150; Fire Marshal: 512-393-7300 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
Hays County Development Services / Hays County Fire Marshal's Office 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 Development Services: 512-393-2150; Fire Marshal: 512-393-7300.
Initial Development Services administrative review may take several business days; a complete overall review time is not published.

Submit Development Services applications through MyGovernmentOnline, choosing Texas and Hays County. Submit Fire Marshal plans, permits, and every building/fire inspection request through https://www.hayscountypermits.com/; the 2026 building fee includes up to two site visits, normally rough-in and final/Certificate of Compliance. New single-family or duplex construction uses a qualified third party for the required foundation, framing/mechanical, and final inspections because Hays County does not conduct them. OSSF applicants must receive Authorization to Construct before installation and county Notice of Approval after inspection; call 512-393-2150 option 3 for OSSF questions.
In unincorporated Hays County, the Fire Marshal enforces the 2018 International Fire Code with Hays County local amendments; the 2018 International Building Code is adopted by reference through Chapter 1 of the IFC for commercial establishments, public buildings, and multifamily dwellings. Related referenced ICC/NFPA standards apply. New single-family houses and duplexes subject to the county's Notice of New Residential Construction require three third-party inspections (foundation, framing/mechanical before covering, and completion); the county does not perform those residential inspections. Floodplain/development work follows the Hays County Development Regulations, and OSSFs follow the county OSSF regulations and 30 TAC Chapter 285. Interior renovation of a single-family house outside the floodplain does not require a development permit; interior work inside the floodplain may require one. Solar panels attached directly to an existing structure do not require a development permit, but a new supporting structure does. Modification of an existing cell tower does not require a development permit unless it adds construction, a slab, foundation, generator, or support building. The county fire/building code does not apply to single-family dwellings, duplexes, triplexes, or purely agricultural buildings with no workers or public access. No Fire Marshal temporary-structure permit is required for tents or membrane structures under 400 square feet or for structures not open to the public. All OSSF installations require a county permit regardless of acreage.
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.
