When is a building permit required?

A building permit is required before construction or remodeling begins because it ensures that the planned work complies with local building codes, zoning laws, and safety regulations. Obtaining this permit prior to starting construction helps to ensure that the work is reviewed and approved by the relevant authorities, mitigating risks of violations or unsafe conditions that could arise during or after the construction process.

When a permit is sought beforehand, it allows the governing body to evaluate the proposed design, its impact on the surrounding area, and its compliance with established standards. Thus, securing a permit before commencing any building activity is a critical step for legal compliance and for protecting the health and safety of the residents and the environment.

The other options do not capture the proper timeline or requirements for obtaining a building permit. A permit cannot be issued after construction is completed, it is not exclusive to commercial properties, and while significant interior changes might require a permit, this does not encompass all construction scenarios that necessitate an approval before work begins.
