Do I need a permit for addition or structural alteration in Norristown?
Yes. In Pennsylvania, addition or structural alteration generally requires a permit, and Norristown is no exception.
Under the Pennsylvania UCC any construction that enlarges or structurally alters a dwelling requires a permit, and enclosed additions trigger full plan review plus the associated electrical, plumbing, and mechanical work. The UCC is administered locally through a municipal office, a certified third-party agency, or the state. Confirm which one has jurisdiction over your property before starting. Additions and structural alterations require full plan review by the Norristown Construction Code Official. Residential review can take up to 15 days, so apply well before your planned start date. Plumbing, electrical, mechanical and energy permits are issued separately from the building permit in Norristown, so a whole house addition usually needs several coordinated permits.
