Do I need a permit for structural support work in Philadelphia?

Yes. Structural work in Philadelphia requires permits from the Department of Licenses and Inspections (L&I). This includes beam installations, load-bearing wall modifications, and foundation work. Unpermitted structural work creates significant liability when you sell or refinance your property — and in many cases, insurance will not cover damage related to unpermitted structural alterations. NK Construction And Design handles the entire permit process for every structural project we undertake. Your project is fully permitted and inspected before final close-out.
