Lot Line Adjustments in Southern California

What is a lot line adjustment?

A lot line adjustment relocates the boundary between two or more existing parcels without creating any new lots. It is the tool adjacent owners use to reconfigure how their land is divided — trading or shifting area across a shared line — in a form your city or county can review and record. We prepare the survey and documents that turn an informal agreement between neighbors into a legally describable change.

When do you need one?

• Moving a boundary between two parcels so each owner gains the shape or frontage they need
• Combining or reconfiguring lots under common or coordinated ownership
• Resolving an encroachment — a fence, driveway, or structure across the line — by adjusting the boundary rather than removing the improvement
• Squaring up irregular parcels before building or selling
• Aligning the legal line with how the land has long been used

What's included in your deliverables

Exact deliverables depend on your project's scope and what the city, lender, or agency requires. Typical items can include:

• A boundary survey of the affected parcels to establish the existing and proposed lines
• New legal descriptions and exhibits for each revised lot
• Support for your jurisdiction's lot line adjustment application, including the maps and documents the agency expects
• Coordination with owners and title as the adjusted area moves between parcels
