Summary
Norwalk measures its main front-yard setback from the center line of the street, not the property line: no residential building may sit closer than 35 feet to that center line. Business and industrial buildings follow the identical 35-foot center-line rule, unless a quarter of the block front is already built to the street line.
B. No building shall, however, notwithstanding any of the above provisions, be constructed, altered or moved nearer than 35 feet to the center line of any street or streets upon which its lot may abut or front. ... § 118-1000. A. Unless otherwise provided by these regulations, in a business or industrial zone, every building shall be required to be set back from the property line such a distance as may be necessary to keep its street wall, walls or covered porches thirty-five (35) feet from the center line of the street or streets upon which its lot may abut or front, except that where twenty-five percent (25%) of the length of a given block front is occupied by buildings on the street line or within one (1) foot of same, no setback shall be required for additional buildings on said block front.

Full Breakdown
Code § 118-900B sets the core residential rule: no building may be constructed, altered or moved nearer than 35 feet to the center line of any street its lot abuts or fronts on. Corner lots get relief under § 118-900A, complying with the setback line on only their narrower street frontage (owner's choice if the frontages match). A small unenclosed entry or portico, up to 8 feet wide and 6 feet deep, is exempt from the setback under § 118-900C, as is a compliant handicapped ramp.
Section 118-900F requires a rear yard along the rear lot line whenever that line sits more than 55 feet back from the nearest street, and § 118-900H sets a 25-foot minimum lot width at the street line. The Common Council can override all of this by establishing its own building line under § 118-900F. Business and industrial zones follow a parallel standard: § 118-1000A requires the same 35-foot setback from the street center line, except that once 25% of a block front's length is already occupied by buildings built to the street line (or within 1 foot of it), no further setback is required for additional buildings on that block.
Section 118-1000F and G add a separate requirement where commercial or industrial property abuts a residence zone: a buffer strip at least 10% of the average lot width or depth, capped at 30 feet, maintained free of litter to the Zoning Inspector's satisfaction.
Violations & Fines
Building nearer to the street center line than these minimums allow is a Zoning Regulations violation. Because §§ 118-900 and 118-1000 do not set their own penalties, the Code's default enforcement provision, § 7-8, applies: a fine of up to $500, imprisonment of up to one year, or both, with each day of the violation a separate offense.
