Building a home may seem like a daunting task, but Kitsap County is here to help. This brochure will provide
a general overview of the density, setbacks, height, lot coverage and impervious surface area covered in
Code 17.420 that is required before building may begin. Please consider the following and know that Kitsap
County is excited to partner with you in order to start making your dream a reality.

Lot Coverage and Impervious Surface Area Setbacks
Lot coverage is calculated by dividing the area of land Setbacks are the minimum distance, measured in feet,
covered by buildings into the total lot area. Impervious that a building needs to be from the front, side and rear
surface coverage is calculated by dividing the total area of property lines. Setbacks are are created for Kitsap

visual interpretation.
How do I find out the setbacks for my project?
• Step 1- Locate your parcel
Visit Parcel Search and choose your search option,
once you enter the information, hit the
“Enter” key on your keyboard.
• Step 2 - Determine Zone of Lot/Parcel
Setbacks are determined by the zone in which your
parcel is located. Once you locate your parcel, click on
the details tab at the top and go to “Land & Location”.
Your zoning is listed as the third item down.
Height • Step 3 – Determine Setbacks for Zone
Height is measured using the roof as the reference data
point. The reference points need to be determined by Refer to the Zoning table below and locate your zone

Building setbacks are measured from the property line to
the exterior wall of the house. However, some items may
project into the setbacks (see table on next page).

Setbacks Continued Front Yard Requirement Exceptions
Adjoining Lots
If there are houses on BOTH adjoining lots (adjoining
front yards) that have front yard setbacks that are
smaller than required by zoning, then the new
home’s minimum front yard setback is the average of the
two adjoining front yard setbacks.
If there is a house on only ONE adjoining lot and the
other adjoining lot is vacant, then the new home’s
minimum front yard setback is the average of the
front yard setback of the house on the adjoining lot
and the required front yard setback.
Solar Access
A front yard setback may be modified in order to
maximize a home’s solar access (see brochure
#14—Exceptions from Residential Zoning and Critical
Area Numerical Standards).
Lots Served by Private Easements
If a property takes its access from a private easement
that has the potential to serve five lots or more, the front
yard setback will be measured from the interior edge of
the easement and not the property line.
