Do You Need a Permit to Remove an Interior Wall? in Verenigde Staten
Sometimes. Removing a load-bearing wall almost always requires a building permit because it changes the structural system of the house — an engineer must design a replacement beam and the work must be inspected. Non-load-bearing partition walls can usually be removed without a permit, but if plumbing, electrical, or HVAC runs through the wall, those trades may trigger their own permits.

Country-specific detail
In the US, removing a load-bearing wall requires a building permit in virtually every jurisdiction. The IRC requires an engineered header or beam sized for the span and load path above — typically a steel I-beam or LVL supported by posts bearing on the foundation. The permit process requires structural engineering plans, an inspection of the temporary shoring before the wall comes down, and a framing inspection of the new beam and posts before drywall. Non-load-bearing partition walls generally don't require a structural permit, but rerouting plumbing or electrical within the wall triggers those respective trade permits. In condos and townhomes, even non-load-bearing walls may require HOA architectural review.
