Procedural walkthrough of minor land division and lot-split requirements in Boise.
This guide summarizes the minor land division process based on the City of Boise Zoning Code and Planning & Development Services procedures. Effective date: 2026-02-15. This is not legal advice.

A minor land division allows the division of a parcel into four or fewer lots without requiring a full subdivision plat, provided all resulting lots meet minimum zoning requirements for the applicable district.
Investor implication: Minor land divisions offer a faster, lower-cost path to lot creation than full platting for small-scale infill projects, but the four-lot maximum limits scalability.
Verify at City of Boise Zoning Code →All resulting lots must meet the minimum lot size, width, and dimensional standards of the underlying zoning district. No variances are granted through the minor land division process.
Investor implication: Undersized or non-conforming parent parcels cannot be split via minor land division unless the resulting lots independently meet all zoning standards.
Verify at City of Boise Zoning Code →Each resulting lot must have legal access to a public street. Access via private easement may be permitted if the easement meets City standards for width, surface, and maintenance.
Investor implication: Landlocked parcels or parcels with substandard access cannot be divided without securing compliant access easements, which may require negotiation with adjacent owners.
Verify at City of Boise Zoning Code →Minor land divisions do not require public hearings or Planning and Zoning Commission review if all zoning standards are met. Administrative approval is granted by the Planning Director.
Investor implication: The administrative review process significantly reduces timeline and cost compared to full subdivision platting, typically completing in 30–60 days versus 6–12 months.
Verify at City of Boise Zoning Code →Utility easements must be dedicated for all new lots to ensure access for water, sewer, power, and other services. Easement locations and widths are subject to City Engineer approval.
Investor implication: Utility easement requirements can reduce buildable area on resulting lots and may require coordination with utility providers before approval.
Verify at City of Boise Zoning Code →If the parent parcel was previously divided via minor land division within the past five years, further division may require full subdivision platting regardless of lot count.
Investor implication: Serial minor land divisions are restricted to prevent circumvention of full platting requirements. Verify division history before acquisition.

This is the most common minor land division scenario in Boise's established neighborhoods. The key constraint is ensuring both resulting lots independently meet all dimensional standards after accounting for utility easements.
R-2 minor land divisions for multifamily development require careful density and parking analysis. The four-lot maximum often limits the scale of multifamily projects that can be achieved without full platting.
Alley-fronting lots are increasingly common in Boise infill projects, but alley access standards are strictly enforced. Verify alley status and width before acquisition.
