Sections:

17.16.005 Intent.
The intent of the R-15 zone is to achieve integration with Sedro-Woolley’s existing building types and configurations; incorporate open street layout similar to existing grid rather than closed circulation systems such as cul-de-sacs; maintain the look of conventional neighborhoods in scale, orientation to the street, style, and appearance; and to avoid creation of large apartment “blocks” separate from other parts of the community. Larger-scale buildings are appropriate in the central business district or when combined with commercial uses in the mixed commercial zone. (Ord. 2058-23 § 1, 2023; Ord. 1484-04 § 6 (part), 2004)

All other setbacks including those to the property lines of the parcel being subdivided, the front and rear setbacks, streets, driveways, etc., shall be maintained.
A. A division of land allowing no minimum side setbacks to interior lot lines shall be permitted; provided, that all other requirements of the zoning district shall remain applicable. Interior lot lines are those that are created as part of the proposed land division.
