3. Existing dwelling units may be subdivided from Accessory Dwelling Units when consistent with the density of the underlying zone.
4. Any additional development of the individual Infill Lots may be limited as a result of the application of development standards to the parcel.
5. Provided that the parcel complies with the underlying development, construction, and infrastructure regulations, each subdivided infill lot is not required to individually conform to lot dimension and setback regulations.
6. Except for existing dwelling units constructed prior to October 1, 2021, a 10-foot building setback shall be provided along the exterior parcel boundary of the original parcel as a whole; there shall be no setback required within individual infill lot lines which are interior to the perimeter of the original parcel.
7. Infill Lot subdivisons must comply with density requirements in PCC 18A.15.020.
8. Infill Lots and structures divided by Infill Lots approved through a recorded Infill Lot Subdivision shall not be considered nonconforming.

Other exterior improvements such as yards, driveways, or garages may be included or excluded from individual infill lots.
10. Any exterior improvements including, but not limited to reconstruction, remodeling, maintenance, and addition shall comply with conditions of approval. Improvements may be limited as a result of the application of development standards to the original parcel or other applicable regulations.

An Infill Lot Subdivision shall include provisions for ingress, egress, and utilities access to and from each Infill Lot by reserving such common areas or other easements over, under, and across the original parcel as deemed necessary to comply with all other development, construction, and infrastructure regulations applied to the underlying site plan including, but not limited to, applicable standards in Title 17B PCC. Such easements shall be recorded with the Pierce County Auditor or created as part of the Infill Lot Subdivision. Common areas may include shared garage, parking, and vehicle access areas; pedestrian paths, drainage facilities; underground utilities; open space; exterior building facades and roofs; and other similar features.
