Which codes and exemptions should I review?
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.
