Codes, exemptions & field inspections

Build to the adopted code. Verify every exception.

This guide translates the available agency record into a preconstruction checklist for structural scope, minor work, and inspection release. The adopted code and the issuing official control when a field condition is disputed.

Regulatory framework

The code baseline for Titus County.

Titus County Environmental Inspection Service is the county's TCEQ-authorized OSSF permitting authority and designated representative and also reviews floodplain requirements for unincorporated development. OSSF work must comply with the county's TCEQ-approved local order, Texas Health and Safety Code Chapter 366, and 30 TAC Chapter 285. County subdivision rules require one acre of usable property for new single-family OSSF lots, whether or not served by public water, and regulate rural subdivision roads and drainage. The county publishes no adopted general countywide IRC, IBC, electrical, plumbing, mechanical, or fire-code edition; incorporated municipalities may impose separate building requirements.

Inspection lane

Obtain the OSSF permitting packet from the Environmental Inspection Service, submit the application, site evaluation and required design/planning materials, and call 903-572-6641 to coordinate authorization to construct and the installation inspection before covering or operating the system. The same office approves subdivision OSSF and floodplain information before a plat goes to Commissioners Court. Subdivision applicants must separately coordinate with the County Clerk at 903-577-6796.

Minor-work playbook

Understand what may be exempt—and what is not.

Titus County states that work on any portion of an existing conventional system's lateral lines requires a new permit. Repairs to solid lines, tank lids, broken chlorinators, sprinkler heads, electrical components, and pumps do not require a new permit. An owner may install the OSSF personally, but anyone hired for OSSF work must hold the appropriate license, except a licensed electrician hired for wiring. Existing small lots created before January 1, 1988 may be approved if state separation distances, site evaluation, and all other local-order requirements are met. No county exemption list is published for ordinary cosmetic or structural building work outside floodplain, subdivision, or septic regulation.

Field rule

A permit exemption generally addresses one narrow construction trigger. It does not automatically waive zoning, land-use, floodplain, shoreline, fire, energy, electrical, utility, septic, or right-of-way requirements. Obtain written confirmation when the project involves a new structure, structural alteration, change in occupancy, or concealed work.

Inspection pipeline

Keep the work visible at every release point.

  1. 1

    Request with lead time

    Obtain the OSSF permitting packet from the Environmental Inspection Service, submit the application, site evaluation and required design/planning materials, and call 903-572-6641 to coordinate authorization to construct and the installation inspection before covering or operating the system. The same office approves subdivision OSSF and floodplain information before a plat goes to Commissioners Court. Subdivision applicants must separately coordinate with the County Clerk at 903-577-6796.

  2. 2

    Preserve access

    Do not cover framing, reinforcement, wiring, piping, damp-proofing, or life-safety work until the required inspection has been completed and documented.

  3. 3

    Close the record

    Retain the approved plans, inspection approvals, correction responses, and final certificate or occupancy release with the property file.

Contractor verification

Verify the builder before the contract is signed.

Use the state licensing system to verify active registration, trade credentials, bond status, and liability coverage where available. Match the legal business name to the proposal and permit application.

Planning reference

Keep the parcel rules beside the building plans.

A building permit is only one part of statutory compliance. Check the local zoning, ordinance, map, or land-use reference before finalizing setbacks, height, lot coverage, access, drainage, or accessory structure placement.

Project questions

Frequently asked questions for Titus County

Who handles permitting for this jurisdiction?

Titus County Environmental Inspection Service and Titus County Clerk Platting and Subdivision Office is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.

How should I begin an application?

No verified online portal was located in the reviewed public materials. Contact Environmental Inspection Service (OSSF and floodplain): 903-572-6641; County Clerk platting: 903-577-6796 and request the current application route before preparing a final submittal.

How long might review take?

Titus County's subdivision rules require the OSSF permitting authority to approve or deny subdivision or development OSSF planning materials in writing within 45 days of receipt. The checklist says complete subdivision documentation should be submitted at least 45 days before requested Commissioners Court consideration. No separate ordinary OSSF or floodplain review target is published.

How are inspections scheduled?

Obtain the OSSF permitting packet from the Environmental Inspection Service, submit the application, site evaluation and required design/planning materials, and call 903-572-6641 to coordinate authorization to construct and the installation inspection before covering or operating the system. The same office approves subdivision OSSF and floodplain information before a plat goes to Commissioners Court. Subdivision applicants must separately coordinate with the County Clerk at 903-577-6796.

Field sequencing matters

The inspector needs to see the work at the right moment.

Code compliance is not only a plan-review exercise. Footings, reinforcement, framing, fireblocking, wiring, piping, insulation, weather protection, and life-safety systems each have points where the work must remain accessible. Build the inspection calendar into the trade schedule instead of treating it as a final administrative step.

When a project qualifies for a narrow minor-work exemption, keep a written explanation of why it qualifies and confirm that related zoning, utility, fire, energy, or environmental rules do not create a separate approval requirement.

Closeout file

Keep the approved plan set, inspection approvals, correction responses, contractor license verification, final certificate, and any occupancy release together. A clean record protects the owner, builder, lender, insurer, and future buyer.
