Building or trade permit check for insulation and air sealing scope

City of Dallas Building Inspection FAQs list adding insulation to a building among work that may not require a permit outside special areas, while the storm repair page says remodel/renovation review is used when major structural wall sections are replaced or electrical or plumbing work is involved. Insulation or air-sealing work should be checked with Planning & Development when it changes assemblies, affects structural areas, or is bundled with trade work.
