Saint Helena planning panel backs ADU ordinance tweaks, adds ride‑share to transit definition while excluding extra height

The Saint Helena Planning Commission on July 7 recommended that the City Council consider adopting revisions to the city's accessory dwelling unit (ADU) ordinance (Zoning Ordinance Amendment 26‑001), approving a staff‑prepared redline with several clarifications and one amendment to the proposed transit definition.

Senior Planner Jackie O'Neil summarized the draft changes as requested at earlier study sessions and in public comment, saying the revisions "increase the maximum ADU size to 1,200 square feet, remove material and roof matching requirements, [and] remove mandatory rent reporting," and that the city will submit the adopted ordinance to the California Department of Housing and Community Development for consistency review. O'Neil told the commission the redline identifies which parts are state law requirements and which are local policy choices.

The commission's discussion centered on three interrelated topics: how the ordinance treats public transit for bonus provisions (parking exemptions and additional height), the scope of objective design standards for ADUs over 800 sq ft, and the city's ability to limit reporting requirements that the state regards as barriers. Staff said the Vine shuttle (the local micro‑transit service) covers most of the city's developed area and that expanding the local definition of "public transit" to include micro‑transit would let more properties qualify for parking relief; the state definition continues to control ministerial timelines and certain minimum allowances.

Vice Chair Firdock, who proposed the amendment the commission adopted, said she wanted the ordinance to "capture ride‑sharing agencies regulated by the California Public Utilities Commission" as locally qualifying transit while making clear the commission did not intend to apply state height flexibilities to that locally expanded definition. "My proposal is to include ride sharing in the definition of public transit," she said, "but to exclude the extra height flexibility that would otherwise follow from the expanded definition." Several commissioners said they supported making the definition more permissive for parking reductions but were concerned about unintended height increases in residential neighborhoods.

Commissioner Lopez said he supported clarifying the transit definition but wanted to preserve local control of neighborhood impacts. "I would be in favor of adding ride sharing to the definition of transit as long as we exempt that from the additional height," he said during debate.

Staff explained that certain height allowances (up to 18–20 feet in specific transit proximity) derive from state law and that the city cannot reduce state‑required allowances where they apply; the commission's adopted recommendation therefore asks staff and the city attorney to craft ordinance language that adds ride‑sharing and micro‑transit for local benefits (for example, parking exemptions) while making explicit that the city's locally expanded definition should not be used to trigger the state law's additional height flexibility except where the state definition applies.

On procedural matters, the commission also confirmed staff's recommendation to strike the words "nonconforming" and "enclosed" from a conversion provision for clarity and to retain objective historic protections and clear measurement definitions. Staff further recommended moving utility regulation language into Title 13 (to come to council) and making rent‑reporting optional rather than mandatory because HCD discourages requirements that could serve as development barriers.

A motion to recommend the ordinance to city council, amended to include ride‑sharing in the local transit definition and to exclude height flexibility from that local expansion, passed on roll call by a 3‑1 vote. The commission did not adopt any ordinance language tonight; staff will prepare the formal ordinance text and city attorney analysis to reflect the commission's recommendation for the city council packet.

Votes at a glance - Approval to forward amended ADU ordinance recommendation to city council: Passed 3–1 (three yes, one no). The commission directed staff to draft the ordinance language consistent with the motion and to provide legal review before council consideration. - Continued item 5.1 (notice correction): Unanimously continued to 07/21/2026. - Minutes approval (06/02/2026): Approved (motion carried with one abstention).

Why it matters The proposal loosens several local hurdles to ADU development (larger maximum unit size, fewer aesthetic matching requirements, and fewer mandatory reporting obligations) while balancing neighborhood concerns about scale by limiting which transit definitions can trigger added height. If the City Council approves the recommendation, property owners could see simpler, more objective standards for creating ADUs and broader eligibility for parking reductions in areas served by local micro‑transit or ride‑share programs. Staff will return ordinance language and legal analysis for the council's review.

Who said what (selected) - Jackie O'Neil, Senior Planner: "This ordinance has been reorganized for clarity...increasing the maximum ADU size to 1,200 square feet, removing material and roof matching requirements, [and] removing mandatory rent reporting." - Vice Chair Firdock (motion sponsor): "I would propose that the definition of public transit include ride sharing agencies regulated by the California Public Utilities Commission." - Commissioner Lopez: "I would be in favor of adding ride sharing to the definition of transit as long as we exempt that from the additional height." - Liza Mikhail, Community Development Director: confirmed Title 13 utility amendments "are not before you this evening" and will be forwarded to city council alongside the ADU ordinance.

What's next Staff will prepare final ordinance language and a city attorney memo reflecting the Commission's amendment and will place the item on the city council agenda for consideration on July 28, 2026.
