General Regulations for Accessory Structures. All accessory structures are subject to the following regulations, unless otherwise permitted or restricted by specific regulations of this section and Ordinance. The maximum height of any detached accessory structure is 20 feet, unless otherwise permitted or restricted by this Ordinance. Setbacks for detached accessory structures are required as follows: Enclosed detached accessory structures must be setback a minimum of three feet from any lot line in all districts and one foot from any lot line abutting an alley, unless otherwise permitted or restricted by this Ordinance. Open sided detached accessory structures must be setback a minimum of one foot from any lot line... The footprint of any single detached accessory structure cannot exceed the footprint of the principal building.

Full Breakdown
3 as "an accessory structure, often purchased pre-built or as a kit in pre-fabricated sections, that is not designed to be served by heat or plumbing and does not need to be placed on a permanent foundation," typically used to store lawn, garden or recreational equipment. A: the maximum height for any detached accessory structure is 20 feet; an enclosed structure must sit back a minimum of three feet from any lot line in all districts, or one foot from a lot line abutting an alley; and an open-sided structure needs only a one-foot setback.
The footprint of a single detached accessory structure, including a shed, cannot exceed the footprint of the principal building on the lot, and sheds count toward the district's maximum impervious surface and building coverage limits. 5 lists sheds as prohibited from the front yard, meaning a shed can go in a rear or side yard but not in front of the house. 12 may still be required before the shed goes up, since a zoning permit confirms the use and structure comply with the Ordinance.
Violations & Fines
A shed built taller than 20 feet, closer to a lot line than allowed, larger in footprint than the principal building, or placed in the front yard without approval is a zoning violation subject to Trenton's general penalty, City Code § 1-17: a fine up to $2,000, up to 90 days in the county jail, or up to 90 days of community service, with each day of continued violation a separate offense under § 1-18.
