You will need to provide an adequate description of the project proposed and some type of drawing or construction plan. Plans may be drawn by a homeowner or contract or/and do not have to be prepared by an architect or design professional in most cases. In general, the more complex the project is, the more detailed the plans will need to be. You will need to provide an estimated cost for the project. If a contractor will be performing the work a copy of the appropriate license will need to be included. If a contractor will have any employees on the property they will need to provide an insurance certificate showing evidence of Worker's Compensation insurance. In most cases, if the information provided by an applicant is complete, a building permit will be issued within a few days at most. The Building Official is allowed up to 30 days under State Statute to review and either approve or deny a building permit.
