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
Under the incorporated state OSSF rule, the authorized agent must approve or deny a complete planning-materials submission within 30 days. For a complete subdivision application, Commissioners Court must approve, conditionally approve, or disapprove it within 30 days; the period may be extended by no more than 30 days under the limited conditions in Chapter 8 of the county regulations. No separate floodplain-review target is 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.

No separate floodplain-review target is published.
Obtain the county's written Authorization to Construct before any OSSF installation. Submit the application, licensed site evaluation, design by a professional engineer or registered sanitarian when required, and installer information to the County Judge's Office. Request the installation inspection at least two days before work unless the designated representative waives that notice, and do not cover tanks or disposal lines before inspection. An aerobic system also requires a recorded affidavit and maintenance agreement before authorization to operate. Call 936-642-1746 to submit or schedule.
Trinity County is TCEQ's authorized agent for on-site sewage facilities and administers its local OSSF order together with Texas Health and Safety Code Chapter 366 and 30 TAC Chapters 30 and 285. The County Judge and emergency-management program administer county floodplain responsibilities, and Commissioners Court applies the county's current subdivision regulations. No adopted countywide IRC, IBC, electrical, plumbing, mechanical, or fire-code edition for ordinary construction outside these programs is published. Incorporated municipalities may impose separate building and zoning requirements. The county publishes a ten-acre OSSF exemption affidavit, but the exclusion is limited to a single-family dwelling on a tract at least 10 acres where no part of the system is closer than 100 feet to a property line, the effluent remains on the tract, the system is not a nuisance or pollution source, and all other state conditions are satisfied. A homeowner may install the OSSF serving the homeowner's own single-family residence when the state owner-installer conditions are met; all other installers must hold the appropriate TCEQ license. The county does not publish a blanket exemption for ordinary structural or cosmetic construction.
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.
