Kuna Lot Split Guide

A lot split is the division of a single lot into two or more lots without the creation of new streets or public infrastructure, processed administratively through the Planning and Zoning Department.

Investor implication: Lot splits are faster and cheaper than full subdivisions because they avoid the platting process and infrastructure requirements. The administrative path means 30-60 day timelines vs. 6-12 months for subdivisions.

Each resulting lot must meet the minimum lot size, width, and depth requirements of the underlying zoning district.

Investor implication: Lot geometry is the binding constraint. A parcel that meets minimum square footage but fails minimum width or depth cannot be split. Measure twice, split once.

Each resulting lot must have legal access to a public street or approved alley.

Investor implication: Alley access is the unlock for mid-block lot splits in Old Town. Parcels without street frontage or alley access cannot be split.

Each resulting lot must be capable of being served by public water, sewer, and other utilities.

Investor implication: Utility stub locations determine whether a split is feasible. A parcel that meets lot size and access requirements but lacks utility service cannot be split.

Existing structures on the original lot must comply with setback requirements for the resulting lots, or a variance must be obtained.

Investor implication: A structure that was legally conforming on the original lot may become non-conforming after the split if it violates the new lot's setbacks. This can block the split or require a variance.
