As a homeowner, you must ensure that you have a building permit before you begin construction or demolition or hire a builder that can apply on your behalf. You need a building permit to erect, install, extend, alter, or repair a building. If you are demolishing all or part of a building, you will need a building permit to demolish. Construction or alterations that result in a material change to a building, foundation work, framing, insulation, plumbing or an accessory structure will require a permit and inspection(s). Our team applies for permits and variances on behalf of our clients.
