Commissioners press staff on limited-density rural dwellings, deed restrictions and AB 1 30 implications

Commissioners used the Jan. 9 planning commission meeting to press staff on how recently adopted and proposed housing rules will work in Mariposa County.

Senior planner Ben Goger told the commission that limited-density rural dwellings (the county's title 25 track) are designed to simplify permitting for owner-builders and reduce certain energy/technical burdens compared with full Title 24 tracks. He said the code will include a notation and deed-related documentation to indicate that structures built under the limited-density standard are distinct and that, in practice, those approvals will include conditions such as prohibitions on short-term rentals. "There will be... some type of deed restriction that gets attached to the limited density rural dwellings... and then it's also going to, say that it can't be used as a short term rental," staff said.

Commissioners raised lending concerns and cited neighboring counties' experience. Staff referenced contacts with Calaveras, Humboldt and Santa Cruz, which have implemented title-25 approaches and reported that lending has generally been available for these structures, but staff advised prospective builders to check directly with lenders and insurers.

A commissioner asked how AB 1 30 (the transcript reference) affects the county's ability to place deed restrictions on ADUs; staff said they are still working through the statute's technical details with the state housing authority and the building division and will follow up with informational packets or a staff presentation. On vehicle-miles-traveled (VMT) and CEQA, staff noted Mariposa County has adopted a local VMT policy that screens many projects from a full VMT analysis and that while the public-resources code allows impact fees in some contexts, staff did not foresee immediate implementation of a VMT impact fee in Mariposa.

Staff committed to return with clearer guidance and technical materials to explain how title 25/LDRD, ADU law, deed notations and lending interact in Mariposa County.
