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.

Project questions
Potter County Road and Bridge Department; Amarillo Area Public Health District Environmental Health is the identified county-level authority for this profile. Confirm that the property is in its service area 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 Potter County Road and Bridge/Floodplain: 806-383-2273; Amarillo Environmental Health OSSF: 806-378-9472; rural 911 addressing: 806-374-9800 ext. 109.
A complete OSSF application must be approved or denied within 30 days under 30 TAC Chapter 285. The Authorization to Construct is valid for one calendar year; if the system does not pass inspection during that period, a new permit is required. The operational permit does not expire while the system is used as approved. Public OSSF record requests may take up to 10 days.
Submit the completed OSSF application, scaled site plan, floor plan, licensed site evaluation, and any required professional design to ehealthOSSF@amarillo.gov, in person, or by mail, with fees. An approved Authorization to Construct is required before work or inspection scheduling. Call 806-378-9472 the business day before the desired inspection with the address, permit number, and installer-attendance information; the system must pass before backfilling. For floodplain or subdivision review, contact Potter County Road and Bridge at 806-383-2273.

Potter County Road and Bridge administers county floodplain and subdivision requirements for unincorporated land; the December 2023 subdivision regulations require drainage analysis identifying the 100-year floodplain, road standards, water-supply certification, and approved sewage plans. The Amarillo Area Public Health District administers Potter County's OSSF Order, 30 TAC Chapter 30 Subchapters A and G, and 30 TAC Chapter 285. The county's more stringent OSSF order requires a permit regardless of tract acreage. No general county structural building-code edition or ordinary residential building-permit program was published for unincorporated property in 2026. No county minor-structure or cosmetic-work exemption list was published because Potter County does not identify a general building-permit program for unincorporated construction. Potter County's local OSSF order removes the state 10-acre permit exemption: installing, repairing, replacing, or altering any OSSF requires a permit regardless of acreage. A homeowner may install or repair a system serving the homeowner's own single-family residence after obtaining the permit and approvals; rental, leased, and commercial property requires a licensed installer.
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.
