§ 17.80.040 Development standards.
A second unit, and both of the units in a two-unit development, shall comply with all of the following development standards:

Size. A second unit, and both of the units in a two-unit development, shall be no smaller than eight hundred square feet and no larger than one thousand square feet in floor area each.
(c)
Height. A second unit, and both of the units in a two-unit development, shall be no taller than sixteen feet in height from ground level and shall be one-story. The units shall not be located on the second or any higher story of a structure.
(d)
Setbacks. No setback beyond the existing setback shall be required for an existing permitted structure or for a unit constructed in the same location and to the same dimensions as an existing permitted structure. In all other circumstances, second units, and both units of a two-unit development, shall be set back at least four feet from the side and rear lot lines.
(e)
Parking.
(1)
One off-street parking space is required for a second unit and one off-street parking space per unit is required for each unit of a two-unit development.
(f)
Separate Entrances. A second unit, and both of the units in a two-unit development, shall have a separate entrance.
(g)
Wastewater.
(1)
Prior to issuance of a building permit for a second unit or either unit of a two-unit development, a video of the sewer lines that will be connected to the unit(s), or another appropriate sewer capacity test, may be required to show there are no sewer line constraints, as determined by the city engineer. Any sewer line constraints shall be resolved to ensure adequate sewer capacity for all units on the parcel, as determined by the city engineer, prior to issuance of a building permit.
(2)
Prior to issuance of a building permit for a second unit or either unit of a two-unit development that will be connected to an onsite wastewater treatment system, the applicant shall provide documentation of a percolation test completed within the last five years, or, if the percolation test has been recertified, within the last ten years. If the city engineer finds that the on-site wastewater treatment system is inadequate to serve the proposed units, the system shall be repaired, replaced, or otherwise modified to ensure adequate capacity for all units on the parcel, as determined by the city engineer, prior to issuance of a building permit.
(i)
Limitation on Enforcement of Development Standards. With the exceptions of the setback requirements in subsection (d) and the requirement to comply with all building codes, the city shall not enforce any development standard to the extent that it would have the effect of physically precluding the construction of a second unit or two-unit development on a parcel, or would physically preclude either the second unit or both units of a two-unit development from being at least eight hundred square feet in floor area.

Notwithstanding any other provision in this chapter, the approval of second units and two-unit developments on a parcel that was created through an urban lot split shall be limited as described in Section 16.40.060.

If a second unit is proposed to be built on a lot with an existing junior accessory dwelling unit, then the junior accessory dwelling unit must be demolished prior to issuance of a building permit for the second unit, pursuant to Section 17.47.050(b)(2). This requirement shall result in the denial of the application for the second unit if destruction of the junior accessory dwelling unit will result in a violation of Section 17.80.030(c) or (d).
