Building Code Permits
Norwalk, Connecticut
April 26, 2026
Permit takeaway
Norwalk Building and Code Enforcement directs applicants to obtain Planning and Zoning review first, then check building-department procedure lists and schedule appointments once the list is complete.
Zoning and placement
Planning and Zoning review can be needed before building review, and exterior equipment such as rooftop units, above-ground LP tanks, exterior oil tanks, and air conditioning condensers must include zoning permit approval.
Building and trade review
Norwalk provides separate guidance for one- and two-family residential work, three-or-more-unit residential work, decks, roofing, windows, siding, fences, walls, and swimming pools.
Call before applying when
Call before applying if the project includes a deck, fence, wall, pool, exterior equipment, roof, siding, windows, three-or-more-unit housing, or a project that begins with zoning review.
