Chapter 19.46
INFILL OVERLAY
Sections:
19.46.050 Development standards.
19.46.010 Purpose.
A. The general purpose of these regulations is to establish infill overlay districts and to prescribe procedures whereby the development of lands within overlay district can occur in a manner that will encourage infill development while protecting surrounding neighborhoods. The specific purposes of this chapter are to:
1. Enable creation of infill lots for smaller housing units that, due to limited floor area, lot size, and/or development restrictions, are likely to be more affordable than typical single-family dwelling units; and
2. Increase the diversity of single-family housing types available to a variety of household incomes, types and sizes. (Ord. 2803 § 2 (Exh. B), 2025).
19.46.020 Intent.
Intent of this chapter is to allow for a variety of lot and home sizes that are typically more affordable than homes and lots developed under the standard zoning code requirements within EMC Title 18. (Ord. 2803 § 2 (Exh. B), 2025).
19.46.030 Applicability.
The cottage infill overlay is supplemental to the underlying zone district and constitutes optional development regulations as an alternative to the underlying development regulations. The cottage infill overlay applies to the R2, R3 and R4 zones. Where there is a conflict between the requirements in this overlay and other sections of the development regulations, this chapter applies. Density maximums outlined in Chapter 18.06 EMC do not apply when developments are using these standards for lots within a subdivision or housing development. (Ord. 2803 § 2 (Exh. B), 2025).
19.46.040 Definitions.
Cottage. A “tier 1 cottage” is a one-story single-family dwelling unit that is not larger than 1,350 square feet of gross floor area excluding covered car parking and unheated covered porches. A “tier 2 cottage” is a one-story single-family unit that is not larger than 2,000 square feet of gross floor area excluding covered car parking and unheated covered porches.
“Cottage lot” means a lot created pursuant to the requirements of this chapter with permanent development restrictions that ensure that development on the lot complies with this chapter.
“Gross floor area” means the total square footage of all floors in a structure as measured from either the interior surface of each exterior wall of the structure or, if the structure does not have walls, from each outer edge of the roof.
“Maximum building coverage” means the maximum percentage of the surface of the subject property that may be covered with buildings. Sum of gross floor area of all buildings on a lot divided by lot size.
Story. As defined by the most recently adopted version of the International Residential Code. (Ord. 2803 § 2 (Exh. B), 2025).
