Understanding minimum lot sizes and parcel splits

Check the zoning designation on your parcel early to avoid incompatible proposals.

When a parcel split is required

Common triggers for a formal parcel split include creating a new legal parcel for sale or development, dividing land for separate ownership, or changing lot lines that affect zoning compliance. Smaller adjustments may qualify as lot line adjustments or parcel mergers under city procedures; consult Planning Division guidance for which application is appropriate.Planning Division[2]
