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)
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)
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.
