A Two-Lot Split, a 1972 Strip Deed, and a Requested Lot Line Adjustment
An owner holds a 4.6-acre parcel improved with a 1950s house, zoned R-1 with a 10,000-sf minimum lot area. He wants to create a second lot for his son by dividing off a 1.1-acre portion with 60 ft of frontage on a county road. The county general plan requires a 50-ft right-of-way, and the road is currently in a 30-ft right-of-way. The owner asks you to "just do a lot line adjustment, it's cheaper and faster, and don't show the dedication." He also produces a 1972 deed that conveyed a 0.2-acre strip between his parcel and the neighbor, which he says "merged" the two lots, and a 1998 building permit for a second dwelling that was never finaled. The county planner says the parcel may have been part of a 1912 tract and that a certificate of compliance might be needed.
1. Can this project be permitted as a lot line adjustment under Government Code section 66412(d)?
Read the worked answer
No. Section 66412(d) allows a lot line adjustment only between four or fewer existing adjoining parcels, with land taken from one and added to an adjoining parcel, and only where the adjustment does not create a greater number of parcels than existed. Dividing one parcel into two creates an additional parcel, so a lot line adjustment is unavailable. The correct path is a parcel map, or a tentative map and parcel map if the local ordinance requires a tentative map for this project, with the county's subdivision review and any dedications or improvements the agency requires. A lot line adjustment also may not be used to avoid dedications or improvements the subdivision process would require. Advise the owner in writing before doing map work; preparing a lot line adjustment exhibit here could look like assisting an evasion of the Map Act.
2. How do you handle the 1972 strip deed, the claimed merger, and the planner's mention of a certificate of compliance?
Read the worked answer
Start with the record. A 1972 deed conveying a 0.2-acre strip does not by itself merge parcels for subdivision purposes. Merger depends on the Map Act, the county's merger ordinance, common ownership, and compliance with notice requirements. Pull the assessor's parcel maps and the recorded deeds, and ask the county whether the parcel is a separate legal lot. If status is unclear, the owner can apply for a certificate of compliance under section 66499.35; the local agency issues it if the parcel complies, and it is recorded. Your job is to research and map the evidence and to state it clearly, not to declare the parcel legal. Also check the 1998 second-dwelling permit; an unfinaled or unpermitted unit can affect zoning compliance and must be shown and noted.
3. The county wants a 10-ft dedication for a 50-ft right-of-way. How do you handle that demand and the owner's instruction to omit it?
Read the worked answer
Dedications can be required as a condition of approval, but they must satisfy the constitutional nexus and rough-proportionality tests (Nollan v. California Coastal Commission; Dolan v. City of Tigard) and the Map Act's findings. The existing right-of-way is 30 ft, or a 15-ft half-width; the general plan calls for 50 ft, or a 25-ft half-width, so a 10-ft dedication is the likely ask. Show the existing and proposed right-of-way on the map and let the county make the demand; do not omit it at the owner's request. Explain the process and any variance or exception route, and make clear that the dedication is a condition of approval, not something the surveyor can waive. If the owner wants to challenge the demand, that is an administrative and legal process, not a mapping decision.
