Waterbury, CT Building Safety: Building Permits (2026)

06 makes it unlawful to commence construction, alteration or addition of any building, or excavation for a building, structure or use, until plans are approved and a permit issued by the Building Official under a formal written application. No permit issues to an applicant delinquent on city taxes, water rents, or sewer use charges, as attested by the Tax Collector. The Building Official can route the application to other city officials for review, including the Zoning Administrator, Fire Marshal, Inland Wetlands Coordinator, City Planner, City Engineer, Director of Health, Traffic Engineer, Superintendent of Waste Disposal, and Superintendent of Water; once submitted to any of these reviewers, the permit cannot take effect without that official's written approval, and the Building Official coordinates the whole process.

Applications must include a plot plan built as a Class A-2 survey map from a Connecticut-registered land surveyor, showing lot lines staked on the ground and the map, proposed construction with front, side and rear yards, off-street parking, accessory buildings, zoning lot area, lot coverage, first-floor elevations, and existing or proposed sewer, storm sewer and water main locations and elevations, unless the Building Official waives an item. Separate Health Department approval is required for on-site sewage disposal. Under division (G), if fabrication has not begun within six months of issuance, or the foundation footing has not been laid within that period, the permit becomes void, though the Building Official may grant a six-month extension.
