Building Permit

The general rule across US jurisdictions is that any work involving structural changes, new living or occupied space, or modifications to mechanical systems requires a permit, while minor cosmetic work does not. Building without a required permit can void insurance coverage for the unpermitted work, create disclosure obligations at the time of sale, and expose property owners to fines and stop-work orders. The permit process — though it takes time and costs money — provides legal protection and quality assurance through inspections.
