Lot Line Adjustment Involving Home Across Two Parcels

[David F.]

I've gone under contract for a home that sits across 2 adjacent parcels in San Diego County.  My intent is to perform a lot line adjustment, sell the resulting parcel that has the existing house and build on the resulting vacant parcel.

However I've been told the following:

"If so, that will be a critical issue to clean up to preserve the two legal lots. Usually, building across a lot line effectively merges those two lots.'

I was just wondering if anyone had any experience in the matter or input as to whether this is the case.

Most people confuse a "lot" with a "parcel" - a lot is created during mapping and may have been done a hundred years ago.  A parcel is the unit of ownership and has a unique number (the Assessors Parcel Number).  Often, the lot and the parcel are 1:1, but in older parts of the City it's also common for a parcel to consist of multiple lots.

Perhaps you already understand this and accurately said the house sits across two parcels.  More, likely, though, the home sits across two *lots*.  What's involved in either case is very different.  I've done several projects that involve mapping changes - it's not as simple as one would expect it to be.
