Digital permit application gateway
Start with the issuing authority’s own submission lane. A complete application package, accurate valuation, and accessible inspection path are the fastest route through statutory plan review.
Recommended first click
Use the official digital gateway to submit plans, monitor review comments, pay required charges, and request inspections when the permit is issued. If the link is unavailable, use the agency website or phone number on the administrative profile to confirm the current lane.
Typical review lane
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.
Treat this as a planning signal, not a guaranteed approval date. Completeness, corrections, resubmittals, and agency workload control the actual clock.
Verify the parcel is inside this agency’s service area and note whether a city, state, fire marshal, septic authority, or utility district also has approval authority.
Prepare legible plans, site information, project valuation, ownership authorization, contractor information, and any energy, floodplain, zoning, or utility documentation the issuing office requires.
Keep the permit number, approved plan set, correction comments, fee receipts, and inspection results together. Those records establish the compliance trail for the next trade.
Application documents
Before submission, call DUAS: 214-653-6565; DCHHS Environmental Health: 214-819-2115; Fire Marshal: 214-653-7970 if the project involves a change of occupancy, structural alteration, accessory structure, demolition, or work near a regulated environmental feature.
Source trail
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.

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.
What makes an application complete
Before you click submit, make sure the drawings agree with the site plan, project description, valuation, ownership authorization, and contractor information. If the work changes structure, occupancy, drainage, fire protection, energy performance, or utility demand, describe that scope plainly. Ambiguous narratives create correction cycles and delay the field schedule.
Save the confirmation number, payment receipt, uploaded plan set, and every correction comment. Those records are the backbone of a defensible compliance file when multiple trades or agencies share responsibility.
Submission quality check
Site: address, parcel, access, setbacks, and existing conditions are consistent.
Scope: structural, mechanical, plumbing, electrical, fire, and energy work is identified.
Closeout: inspection contacts and the final approval path are understood before work begins.
