Summary
Trenton lets porches, stoops, and steps project onto the public sidewalk only within strict limits, and bars any such encroachment outright in the Downtown Business A Zone unless City Council grants a variance. City Code § 42-5 sets maximum projection distances, a four-foot minimum clear sidewalk width, and a public-hearing variance process for business-zone encroachments.
A. Porch and step encroachments. (1) ... Where the steps approach from the front or at right angles to the street line the combined projection beyond the street line, including both platform and steps, shall not exceed 5/12 of the total width of the sidewalk... Where the steps approach from the side or parallel to the street line the steps and porch platform shall not extend more than four feet beyond the street line... B. Minimum sidewalk width. In no case shall any porch, stoop, steps or other projection, appendage or building addition be constructed so as to leave less than four feet of clear and unobstructed sidewalk... C. Encroachments; business zone. (1) Prohibited. No porch, stoop or steps, decks, projection, appendage or addition to a building shall be constructed in a manner which encroaches upon any part of a public sidewalk in the Downtown Business A Zone, regardless of whether the encroachment would leave a remaining width of four feet or more, as required in other zones.

Full Breakdown
Section 42-5A governs porch and step encroachments citywide. Steps approaching from the front, at right angles to the street, cannot project beyond the street line by more than five-twelfths of the sidewalk's total width, and the platform and steps cannot exceed half the building's front width. Steps approaching from the side, parallel to the street, cannot extend more than four feet beyond the street line. No covered porch, stoop, or steps may project beyond the street line at all. Section 42-5B sets a citywide floor: no porch, stoop, step, or other projection may leave less than four feet of clear, unobstructed sidewalk, though the Construction Official has discretion to set special dimensions where an existing sidewalk or porch cannot fully comply.
The Downtown Business A Zone gets a stricter rule under § 42-5C: no porch, stoop, step, deck, projection, appendage, or addition may encroach on the public sidewalk there at all, even if four feet of clearance would remain. A business owner can still seek a variance from City Council, but only after a public hearing and only on findings that the structure will not be aesthetically detrimental to the neighborhood, complies with the construction code and zoning chapter, leaves sufficient room for pedestrian traffic, serves a specific public convenience, and has been cleared by the traffic and parking director for vehicular safety.
Violations & Fines
An encroachment built without meeting § 42-5's dimensional limits, or built in the Downtown Business A Zone without a City Council variance, is treated as an unpermitted structural encroachment on the public right-of-way and is enforceable under Chapter 42's general violation and penalty provisions in § 42-1E, tied to Chapter 1's General Penalty and the State Uniform Construction Code.
