Lot Split and Minor Subdivision
Split one parcel into two or a few lots, with the survey, plat and engineering your county needs to approve it. Typical US fees run $2,000 to $15,000, and most projects take 1 to 6 months. Our drawings, calculations and reports are sealed by a Professional Engineer (PE) licensed in the state where your project is located, ready for permit submission.

What the work involves
A lot split or minor subdivision divides a parcel into a small number of lots without new streets. The land surveyor prepares the plat or survey, and an engineer may be needed to show each lot has access, drainage and a sewer connection or septic area that passes soil testing. Requirements vary widely, and some jurisdictions handle these administratively.
