Building permit. No person, firm, corporation, association or other organization shall commence the erection, construction, enlargement, alteration, improvement, removal or demolition of any commercial building or structure, except a nonresidential farm building, including barns, sheds, poultry houses and other buildings used directly and solely for agricultural purposes, nor install heating equipment, nor shall any excavation be made or footing or foundation be constructed without having applied and obtained a permit from the Building Inspector. However, no permit shall be required for the performance of necessary repairs which are not of a structural nature and which are done in conformance with the Uniform Code identified in Chapter 62 of the Town of Ballston Town Code. A nonresidential farm building only includes buildings and property which meet the requirements for an agriculture assessment and the eligibility requirements as defined in the Assessor's Manual Section 305. Site plan review is required whenever a use requires site plan review as described in Article XXXII of this chapter. The Building Inspector shall not issue a building permit until site plan review has been completed by the Town Planning Board. The Building Inspector shall refer all applications for a building permit to the Planning Board for site plan review if it appears to the Building Inspector that the proposed construction, alteration or repair meets the criteria for site plan review. Site plan review under Article XXXII of this chapter shall be required before the issuance of a building permit for any building proposed to be placed on any new or existing commercial site.
