Creates a definition
Accessory apartment means one or more rooms
with private bath and kitchen facilities
comprising an independent, self-contained
dwelling unit within or attached to a single family
dwelling or in a detached building on the same lot
as the primary dwelling unit. An accessory
apartment is distinguishable from a duplex in
that, unlike a duplex, it is clearly subordinate to
the primary dwelling unit, both in use and
appearance.
Currently
o A one bedroom or efficiency unit up to 600
square feet in net floor area.
o Areas common to more than one dwelling unit—
including entryways, furnace rooms, laundry
rooms, and interior stairways—shall not be
included in the computation of the net floor area
for the accessory apartment.
o One on-site parking space
Currently
o On a lot 100% or larger than the minimum lot

building permit is needed.
o On a lot less than the minimum lot size an
approved conditional use permit is required.
o On a lot (any size) not served by City sewer an
approved conditional use permit is required.
Review and considerations
o What are other communities doing?
o What are the possible impacts (traffic, noise,
parking, neighborhood harmony etc.)?
o Table of Dimensional Standards and the Table of
Permissible Uses.
Table of Dimensional Standards
o Lots smaller than the minimum – a single family
dwelling and w/approved conditional use permit a
600 sq. ft. accessory apartment.
o Lots 100% of the minimum lot size – a single family
dwelling and a 600 sq. ft. accessory apartment.

What was adopted….
o On lots 125% of the minimum lot size an
efficiency, one bedroom, or two bedroom unit
that has a net floor area equal to or less than
50% of the primary dwelling unit’s net floor area
but not to exceed 1,000 square feet only a
building permit is needed.
o 1 on-site parking space needed.
What? An example
o D5 Zoning – on a lot 9,000 square feet (more
than 125% of the minimum lot size).
o House (primary dwelling) is 1,600 square feet.
o Accessory apartment could be up 800 square
feet (equal to or less than 50% of the primary

In multi-family zones (i.e.

o Allows a smaller accessory apartment on a lot
too small for a second unit with an approved
conditional use permit.
