Definition: A deck is an uncovered and open platform built above grade and attached to a
principal or accessory building, typically supported by pillars or posts. Decks are considered to
be part of a building or structure. Setbacks shall be measured from the outermost portion of the
deck.
Decks shall be constructed on a building’s rear façade / elevation or on an interior side
elevation not visible from the street. Decks on side elevations will be permitted if it can be shown
that they are characteristic of the house’s overall architectural style, subject to exterior design
standards-see Article VIII, Section 30-241 (C)(3). Decks are also permitted on corner-side
elevations of corner lots facing a lake, park, or other amenable feature. Decks shall be
designed to be consistent and compatible with a house’s architectural style and include
elements such as posts, railings and balusters, and be constructed in cedar, cypress, redwood, or
appropriate composite materials such as wood sawdust or material composite / high density
polyurethane plastic (HDPE), plastic and aluminum. Decks constructed in pressure-treated
lumber, shall be painted or stained, after a curing / drying period of no greater than 18 months.
Decks located within 5’ of the Principal Structure (House) shall meet the following setback
requirements:
Front / Street Yards: 25 feet *Note: Corner lots have 2 front yards
Rear Yard: 20 feet
Side Yard: 3 feet
The above setbacks are for decks that are greater than 12 inches above grade and located
within 5 feet of the principal structure. In no case can the proposed deck project any farther
into the required setback areas than the principal structure.
NOTE: Decks less than 12 inches above grade may project within 3 feet of the side lot line
however they must still meet all other setback requirements.
Decks located further than 5’ from the Principal Structure (House) shall meet the following
setback
requirements (the deck must be located behind the front plane of the principal structure):
Front / Street Yards: 25 feet
Rear Yard: 5 feet
Side Yard: 5 feet
NOTE: Decks less than 12 inches above grade may project within 3 feet of the side lot line
however the rear lot line must meet the 5 foot setback.
