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
Dallas County Department of Unincorporated Area Services (DUAS); Dallas County Health and Human Services Environmental Health; Dallas County Fire Marshal 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 DUAS: 214-653-6565; DCHHS Environmental Health: 214-819-2115; Fire Marshal: 214-653-7970.
The July 2025 Dallas County OSSF application instructs applicants to allow a minimum of 30 working days for application and planning-material review before a permit to construct is issued. Development permit timing is N/A; a complete application file remains open for one year, but no work is authorized until permits are approved and issued.
Create an account and select Texas > Dallas County Unincorporated in MyGovernmentOnline (mgoconnect.org) for DUAS permits, including development, floodplain, residential, and OSSF-related submissions. For septic, submit the completed OSSF application with required site evaluation/design and supporting documents to DCHHS Environmental Health; after approval the county issues Authorization to Construct and inspects the installation. Pre-development meetings are held the second and fourth Tuesday monthly after application. Contact DUAS at 214-653-6565 or Environmental Health at 214-819-2115.
In applicable unincorporated areas, Dallas County has adopted the 2021 International Residential Code under Local Government Code authority; the Dallas County Fire Code also governs applicable fire/life-safety work and commercial construction. County regulations cover unincorporated floodplain development, septic tanks, residential construction/inspection, subdivisions, nuisance conditions, communication facilities, and commercial buildings. City limits and municipal ETJs may require municipal permitting instead. Dallas County permits apply only in unincorporated areas; work inside a municipality is handled by that city. County residential construction notices apply to new residential units and additions/major renovations, with the county zoning page specifically identifying new units or additions of at least 500 square feet outside a city ETJ. No broad cosmetic-work exemption list was published; contact DUAS for project-specific applicability.
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.
