ADMINISTRATIVE REVIEW OF DETACHED ACCESSORY STRUCTURES
& APPLICATION TO INCREASE HEIGHT AND/OR FLOOR AREA
All detached accessory structures must meet zoning code standards intended to prevent accessory structures
from becoming the predominant element on site. Accessory structures must be subordinate in area to the
principal structure on site. Note: This handout does not apply to detached accessory dwelling units.
This handout identifies general requirements associated with detached accessory structures. It is not meant to
be a comprehensive guide as each property has unique characteristics and additional requirements may apply.
GENERAL REQUIREMENTS FOR ALL DETACHED STRUCTURES
Maximum Footprint
676 square feet or 10% of the lot area, up to 1,000 square feet (537.60 Maximum floor area). In
order to exceed 676 square feet, you must match the principal structure in exterior materials and
roof pitch. If exceeding 676 square feet, the administrative height/floor area application is required.
Building Coverage
Principal and accessory structure coverage is limited to 45% of the lot area (546.140 Maximum Lot
Coverage).
Impervious Surface
Coverage
Impervious surface coverage is limited to 60% of the lot area this includes all structures,
driveways, walkways, steps, decks, porches, and generally everything other than grass and
landscaping (546.150 Impervious Surface Coverage).
Gross Floor Area
The gross floor area of the principal structure must be greater than the gross floor area of the
accessory structure(s).
Eave Projection
Eaves cannot be closer than six (6) inches to the lot line (535.280 Permitted Obstructions);
Building Code standards require that the eave is not closer than eight (8) inches to the lot line.
Distance from
Dwelling
All detached structures must be at least six (6) feet from habitable space excluding detached ADU’s
(537.80 Distance from Dwelling).
Distance from
Adjacent Dwelling
The detached accessory structure cannot be located closer than 10’ to habitable space of an
adjacent property dwelling (535.280 Obstructions in Required Yards).
HEIGHT: Detached accessory structure height is measured from grade to the highest roof point of a shed/flat
roof, the midpoint between the peak and the eaves for hip, gable, and gambrel roofs, and the deck level of a
mansard roof.
WALL HEIGHT: The wall
height is measured from
grade to the exterior
intersection of the wall
and the roof rafters for
hip, gable, or flat roofs
and to the low eave side
for shed roofs.
The height of the
detached accessory
structure determines the
standards required. The height of structures is broken into three sections; each section has different requirements
and standards. See the table on the following page for requirements:

12 or 14 feet.
