Norwalk Connecticut DPW and Occupancy Permit Guide

Norwalk driveway, road opening, excavation, fill, encroachment, sewer, stormwater, housing code, pool, septic, and certificate-of-occupancy issues should be checked before site work or occupancy changes.

Permit takeaway

Norwalk's DPW Permit Division oversees road openings, excavation and fill, driveways, encroachments, sanitary sewer lateral tie cards, stormwater design, and erosion and sediment control review.

Zoning and placement

DPW permits, health permits, housing code enforcement, and building permits can overlap when a project changes site access, drainage, sewer, occupancy, or multi-dwelling use.

Building and trade review

Norwalk housing code guidance says apartments in buildings with three or more housing units require a certificate of occupancy after vacancy unless a stated owner-occupied exception applies.
