Summary
New Haven's zoning ordinance treats an attached carport as a building projection, letting it reach into a required yard by no more than three feet and never within five feet of a lot line.
[Section 1, definitions] PROJECTION means any structure attached to a principal or accessory building and extending beyond the face of a building foundation wall, including roofs, cornices, chimneys, bay windows, shading devices, shelters, carports, balconies, outside stairways, fire escapes, steps and open porches... [Section 25(b)] A projection from a building may extend into a required yard for not more than one-third of the width of such required yard... or three feet into such required yard for all other projections, and in no case to within five feet of any lot line.

Full Breakdown
The zoning ordinance's Article I definitions list carports among projections, structures attached to a building that extend beyond its foundation wall. Section 25(b) then sets how far any projection may reach into a required yard: up to one-third of the yard's width, capped at three feet for most projections, five feet for fire escapes, one-story open porches, and entry steps, and never closer than five feet to any lot line. A detached carport instead functions as an accessory building or garage, governed by Section 24's 12-foot height limit and Section 25(d)'s yard placement rules.
Violations & Fines
A carport that projects further into a required yard than Section 25(b) allows, or comes within five feet of a lot line, is a zoning violation subject to a stop-work order and removal.
