Original Parcel Size.

Only parcels 2,400 square feet and larger are eligible for a ministerial lot split.

Resulting Parcel Size.

An SB-9 lot split cannot result in a parcel more than 60% or less than 40% of size of the original lot, and both newly created parcels must be at least 1,200 square feet.

Prior Lot Splits.

Any parcel established through the prior exercise of an urban lot split under SB-9 is not eligible. You may not use SB-9 to subdivide a parcel twice.

Adjacent Lot Splits.

Parcels where either the owner of the parcel, or any person acting in concert with the owner, has previously subdivided an adjacent parcel using an urban lot split under SB-9 are also not eligible.

Post-Project Owner Occupancy.

SB-9 lot split projects require the applicant sign an affidavit stating that the applicant intends to occupy one of the housing units as their principal residence for a minimum of three years from the date of the approved lot split. This requirement does not apply if the applicant is a community land trust or a qualified nonprofit corporation.

Lot Split Easements. Projects that include a lot split may require easements for utility connections and physical access, depending on the lot split configuration. Easements must meet all applicable fire and building safety code requirements.
