How this jurisdiction calculates the fee
Dallas County charges no building-code permit fee for residential construction, because it does not review or inspect houses against a building code. Its published DUAS fee schedule is a development fee schedule: Development Permit Level 1 is $35.00, Levels 2 and 3 are $100.00 and Level 4 is $250.00, and the residential intake is the Notice of Residential at $50.00. The schedule does carry a line labelled 'Residential Building Permit - $100.00', but the county's own application list contains no standalone residential building permit and routes new residential construction, additions and major renovations to the Notice of Residential Construction application, so treat the $100.00 line as a development-permit-level charge rather than evidence of code enforcement, and confirm with DUAS. Septic is priced separately by Dallas County Health and Human Services Environmental Health.
