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 Smith County.

Smith County's current official ordinance library states that, other than subdivision regulations, the county has no local building policies for construction in unincorporated areas. Regulated flood-hazard development is governed by the Smith County Flood Damage Prevention Ordinance and applicable NFIP standards, including elevation or floodproofing requirements two feet above base flood elevation. Subdivisions are governed by the current Smith County Subdivision Regulations. OSSFs are governed by Texas Health and Safety Code Chapter 366 and 30 TAC Chapter 285 through the county's authorized program.

Inspection lane

For floodplain development, submit the county form and required scaled plans/elevation information to the County Engineer/Floodplain Administrator and contact Road & Bridge at 903-590-4801 for review and any inspection requirements. For a new or repaired OSSF, begin with a licensed installer; the installer coordinates the site evaluation, design, permit, and required inspections with RTS Environmental LLC. Call RTS at 903-630-4234 to verify whether a permit is required and to coordinate OSSF inspection; systems must be maintained and inspected.

Minor-work playbook

Understand what may be exempt—and what is not.

The county publishes no general permit requirement for ordinary building or cosmetic work in unincorporated areas outside its floodplain, subdivision, right-of-way, and OSSF authorities. In flood-hazard areas, listed low-damage unrestricted uses include qualifying agriculture, lawns, gardens, parking/play areas, and certain recreation or open-space uses; other development requires a county permit. A single-family OSSF on a tract of at least 10 acres needs no planning materials, permit, or inspection only when it causes no nuisance or groundwater pollution, every component is at least 100 feet from the property line, effluent remains onsite, and it serves the tract's only dwelling.

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.

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.

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.
