Planning commission directs staff to finalize broad housing code updates covering ADUs, density bonuses and workforce housing definitions

The Mariposa County Planning Commission on Jan. 10 reviewed a package of draft development-code articles intended to expand housing options in the county and directed staff and the commission’s contractor to prepare final text for later review and submission to the board of supervisors.

Commissioners and staff discussed several interlocking topics: accessory dwelling units (ADUs), clarified language to reflect recent state amnesty for unpermitted ADUs built before 2020, new density-bonus tables and incentives, and definitions and new typologies for workforce and employee housing including seasonal and remote labor-camp-style accommodations. Ben Gover, senior planner, told commissioners that public comment on the housing articles had been received and that staff would incorporate direction from the commission before returning final legal articles.

Why it matters: Commissioners framed the update as an effort to increase housing opportunities countywide while complying with state law and preserving flexibility for future funding programs. Several changes identified in the draft would change how the county processes ADU permits, how the county treats employee/seasonal housing, and how large density bonuses might be granted to incentivize development.

ADUs and state amnesty: Staff highlighted that recent state action referenced in public comment — cited in the packet as “AB 25 33” — effectively offers a form of amnesty for ADUs built without permits before 2020. Gover noted existing draft code language that would require issuance of permits (where appropriate) within 60 days and referenced internal code cross-references (e.g., sections the packet cites as 17.54 and related code). Commissioners asked staff to add an explicit cross-reference to the state amnesty language in the code text; commissioners agreed that an explicit, short text change could be made to memorialize the state amnesty and to clarify that the local permitting pathway would reflect it. The draft also includes a new limited-recorded declaration (less restrictive than a deed restriction) to document that certain ADUs are not used for stays shorter than 30 days; staff said the text places a simple recorded note on the property so the county can monitor short-term rental restrictions.

Density bonuses and incentives: Commissioners pressed staff to expand the county’s density-bonus options. The draft includes director-level discretion to grant additional incentives or concessions and a separate section that would authorize larger bonuses for specific projects. Commissioners repeatedly said they wanted the consultant to come back with the “most flexible density bonus program you can do under state law.” Staff said the draft currently follows state-prescribed tables for categories such as very low-, low- and moderate-income projects but that the consultant will be asked to prepare alternative tables and language so the county can consider offering larger incentives for workforce and moderate-income housing if the board of supervisors accepts any legal risk.

Workforce and employee housing: The draft recommends a formal workforce-housing typology and separate definitions for employee housing and seasonal (temporary labor-camp) housing. Staff recommended defining workforce housing as 80–120% of area median income where programs require that dollar threshold (to align with California Department of Housing and Community Development programs), but commissioners expressed a broader intent: many commissioners said they want the code to enable housing regardless of income band and to avoid zoning-form obstacles that would block housing types intended for workers. The draft adds an “employee housing” definition applying to up to six employees in a dwelling and a separate “seasonal employee” / temporary labor camp typology (the staff memo cites state HCD and OSHA provisions used for such camps). The Yosemite Conservancy had proposed a “remote labor camp” definition with objective design standards for seasonal worker camps; commissioners agreed they would direct staff and the consultant to consider that language and to explore expanding it beyond the Yosemite West zone and to allow non-employer-owned workforce housing when appropriate.

Next steps: Commissioners directed staff and the contractor to return with working articles in final form and to prepare them for Planning Commission review on Jan. 29 and again for a February 21 meeting with the consultant. Staff said the final draft will cross-check state statutes and existing county cross-references, and that the Board of Supervisors and county counsel will ultimately decide legal risk and final policy tradeoffs.

Ending note: Staff emphasized the changes are intended to increase local housing options while remaining consistent with state programs and funding rules.
