Fees, valuation & enforcement
Permit fees are a project input. Enforcement exposure is a project risk. Use the official schedule where available, then confirm valuation, trade permits, plan review, and inspection charges with the Authority Having Jurisdiction.
Official fee pathway
The final charge may depend on declared construction value, occupancy classification, square footage, plan review, state surcharges, trade permits, technology fees, and inspection activity. Do not use a neighboring city’s fee table as a substitute for this jurisdiction.

Ask the counter to confirm current charges before submitting a project with multiple trades or a change of use.
Financial exposure
Plan for building, mechanical, plumbing, electrical, fire, energy, zoning, septic, right-of-way, or other reviews that the project scope triggers. The lowest initial permit fee is not always the lowest project cost.
Enforcement exposure
When work begins without authorization, the agency may halt the site, require corrective plans, impose additional fees, withhold inspection release, or require concealed work to be exposed for review.
Closeout exposure
A missing final inspection or certificate can complicate occupancy, refinancing, sale, insurance, and utility connection. Preserve the approved plans and signed inspection record through closeout.
Professional field note
Even when a cosmetic or minor project does not require a building permit, zoning, floodplain, shoreline, historic, utility, fire, or right-of-way controls may still apply. Confirm the full jurisdictional picture before work starts.

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
This record is marked State Fallback. Confirm whether a city, state agency, or other local authority controls the parcel 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 806-647-4451 (Castro County Judge/Floodplain Administrator); 806-353-9251 (TCEQ Region 1, Amarillo).
TCEQ OSSF permitting authorities must approve or deny complete planning materials and permit applications within 30 days of receipt; no Castro County general building-review timeline is published.
For septic work in Castro County, use TCEQ’s county permitting-authority search, submit the TCEQ OSSF application and required planning/site-evaluation materials to the authorized authority, and contact TCEQ Region 1 at 806-353-9251. Castro County’s floodplain administrator is the County Judge at 806-647-4451; contact that office before development in a mapped or regulated flood area. No general county building-inspection schedule was published.
Castro County’s official site publishes no general unincorporated building-permit program or building-code edition. The County Judge is the listed Castro County floodplain administrator and county floodplain development is subject to the applicable county/federal floodplain requirements. TCEQ Region 1 is the OSSF permitting fallback and applies Texas Health and Safety Code Chapter 366 and 30 TAC Chapter 285. Incorporated municipalities may impose their own building codes. No Castro County cosmetic-work exemption list was published. For OSSF work under TCEQ rules, the conditional 10-acre single-family exemption requires a licensed site evaluation, one qualifying dwelling on a tract of at least 10 acres, on-site effluent disposal, no nuisance or groundwater pollution, and all system components at least 100 feet from property lines. Defined emergency repairs may proceed without advance approval if reported in writing within 72 hours; grandfathered systems may qualify only when all state conditions are met.
Why permit costs vary
Building departments commonly calculate charges from valuation, occupancy, floor area, project type, plan review effort, trade scope, state surcharges, and inspection activity. A remodel that appears small on paper may still trigger structural, energy, fire, or utility review. Ask the permit counter which disciplines apply before you finalize the construction budget.
The same discipline applies to enforcement. Correcting unpermitted work after finishes are installed can require demolition, revised plans, additional inspections, and schedule disruption. Authorization is usually the less expensive project-management decision.
