Permits are required for most remodeling projects in an existing single-family house. Even if the remodel won’t change your home’s footprint or will only be done in a basement or attic, you’ll need a permit.
If your remodel will change your home’s footprint, you’ll need a plan review and a permit. Home remodeling projects that change your home’s footprint include an addition, a detached garage, a porch, a deck, or a patio. If your remodel consists of a new home addition or a new building, you’ll need to apply for a building permit. Plans are subject to review and approval by the building department.
If remodeling results in more than 50% of the original home’s footprint being added or altered, you’ll have to apply for a site plan review and a permit.
