Construction of an addition/expansion to an existing nonresidential or multifamily structure requires a nonresidential & multifamily building permit. An addition/expansion includes work that increases the floor area (square footage) of the existing nonresidential or multifamily structure.
Addition/expansion construction must comply with the minimum structure size, setbacks, exterior materials and design requirements, landscaping, and other standards of the Zoning Ordinance. Prior to submitting an application for an addition/expansion, a site plan application must be submitted and approved. Please check with Development Services staff to determine applicable standards and requirements.
