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
Navarro County Planning & Development Office 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 Planning & Development: 903-875-3311; OSSF program: 903-875-3313 and request the current application route before preparing a final submittal.
OSSF applications received by mail are reviewed within 30 working days. In-person plan-review appointments must be confirmed 24 hours in advance and typically take 30-60 minutes. No fixed building or floodplain review time is published. The OSSF application expires after one year if inspection is incomplete; a lake-area building permit becomes void if authorized work is not completed within 12 months after work commences.
For covered residential work, the builder contracts with a qualified engineer, architect, TREC inspector, municipal plumbing/building inspector, or ICC residential-combination inspector for three inspections: foundation before concrete, framing and mechanical systems before drywall, and completion. Submit all reports before the county issues the completion certificate. For OSSF work, obtain authorization to construct, leave the system uncovered, and arrange inspection in advance with the county Designated Representative at 903-875-3313; a Notice of Approval follows a passing inspection.
International Residential Code published as of May 1, 2008 for new single-family houses and duplexes and additions increasing an existing residence's area or value by more than 50 percent in unincorporated Navarro County; Richland-Chambers Lakeshore Area Zoning Ordinance and building-permit requirements within 5,000 feet of the reservoir's normal shoreline; county Flood Damage Prevention Court Order/NFIP standards; county OSSF rules and 30 TAC Chapter 285; county subdivision and manufactured-home-rental-community regulations. The county residential-construction order does not apply to manufactured homes built under Texas Occupations Code Chapter 1201 or modular homes under Chapter 1202. Its IRC inspection mandate is limited to new single-family houses or duplexes and additions that increase the existing building's square footage or value by more than 50 percent, so ordinary repairs and smaller additions are outside that order; lake-area zoning and floodplain approvals may still apply. The county's current development acknowledgment says all new, modified, or repaired septic systems require a permit.
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.
