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
Johnson County Development Services is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
No verified online portal was located in the reviewed public materials. Contact 817-556-6380; fax 817-556-6391 and request the current application route before preparing a final submittal.
A typical review timeline was not verified. Ask the agency for its current completeness and review estimate.
Email complete PDF applications and supporting documents to development@johnsoncountytx.org; photographs of documents are not accepted. The current residential packet requires the recorded deed, sealed survey or filed plat, assigned 911 address, site plan and project details, plus any applicable driveway, ETJ, floodplain, stormwater, well, or OSSF documentation. Development Services contacts the applicant after approval or if more information is needed. Obtain and visibly post the yellow permit before construction. For OSSF work, submit the applicable residential or commercial application and planning materials, await authorization, leave the installation uncovered, and coordinate the county inspection at 817-556-6380.
Johnson County requires a development permit before any new residential, commercial, or manufactured-home development begins in unincorporated areas. Its 2019 Flood Damage Prevention Order defines development broadly to include buildings, structures, mining, dredging, fill, grading, paving, excavation, drilling, storage, and floodplain fences; flood-zone projects may require form-board surveys and elevation certificates. Development Services also administers OSSF review and inspections under Texas Health and Safety Code Chapter 366 and 30 TAC Chapter 285, plus the subdivision, drainage, infrastructure, road, right-of-way, stormwater, junkyard, and slaughterhouse requirements applicable to a project. The county expressly states that it does not require or perform general building-code inspections or issue certificates of occupancy; incorporated-city projects must follow the relevant municipality's building requirements. No countywide ICC structural-code edition is published. No general cosmetic-work exemption list is published. The county development permit applies to any new development in unincorporated Johnson County; an accessory development without plumbing has a separate reduced fee, not a permit exemption. Incorporated-city projects are directed to the municipality, and city extraterritorial-jurisdiction platting may also apply. OSSF permit exceptions under state minimum rules should not be assumed without Development Services confirmation, because local requirements and site conditions control.
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.
