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
After a successful OSSF inspection, the county states that a Notice of Approval is issued in approximately seven working days. OSSF Authorization to Construct is valid for one year. The floodplain development permit is also valid for one year and must be renewed if work is not completed in that period. No initial floodplain or OSSF application-review time was published.
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.

Presidio County Floodplain Administrator and OSSF Designated Representative 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 Presidio County Judge/Floodplain office: 432-729-4452; OSSF Designated Representative and Road and Bridge Supervisor Ruben Carrasco: 432-229-3528 or 432-386-0971 and request the current application route before preparing a final submittal.
After a successful OSSF inspection, the county states that a Notice of Approval is issued in approximately seven working days. OSSF Authorization to Construct is valid for one year. The floodplain development permit is also valid for one year and must be renewed if work is not completed in that period. No initial floodplain or OSSF application-review time was published.
For floodplain review, submit the signed development application and a vicinity map; if the site is in a floodplain, include one copy of construction plans and specifications. For OSSF work, submit the application, fee, licensed site/soil evaluation, technical sheet, two copies of planning materials, and accurate directions to the County Judge and Designated Representative. After Authorization to Construct, contact Ruben Carrasco at 432-229-3528 or 432-386-0971 at least seven working days before the required inspection. Do not cover the system before inspection.
Presidio County requires a county floodplain development permit and applies FEMA flood-hazard maps and best available flood data to residential and nonresidential new construction, substantial improvements, fill placement, and alteration of waterways or drainage courses. The county OSSF Order and 30 TAC Chapter 285 govern new, modified, and repaired septic systems. Border-county subdivision compliance under Texas Local Government Code Chapter 232, Subchapter B, also requires qualifying property outside Marfa and Presidio city limits to obtain a county Certificate of Compliance before new utility service. No general county structural building-code edition was published for unincorporated construction in 2026. No county minor-structure or cosmetic-work exemption list was published. The floodplain administrator may issue an exemption certificate when the proposed site is outside an identified special flood-hazard area, but that certificate does not waive other federal, state, or local permits. The county's current OSSF packet does not publish an acreage-based permit exemption; applicants should obtain a county determination before septic work.
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.
