Council adopts amendments to companion‑unit rules, adds junior‑unit category after wide public comment

The San Diego City Council voted 8–1 on Sept. 12 to adopt amendments to the land development code that revise companion‑unit rules and create a new junior‑unit category, after more than an hour of public testimony and detailed staff clarifications.

Supporters said the ordinance would add modest housing supply and provide rental options for local workers; neighborhood groups and historic‑preservation advocates warned the one‑size‑fits‑all approach could harm community character, worsen parking and increase short‑term rentals in certain overlay zones. Phil Martin of the La Jolla Community Planning Association told the council the ordinance "requires only half a parking space per bedroom and no parking spaces for junior units," and urged carve‑outs for campus and beach overlay zones.

Staff and council members fielded multiple technical questions. Edith Gutierrez, development project manager in the planning department, said companion units within garages may use replacement driveway parking; otherwise, units that do not meet parking exemptions must provide parking at a 0.5‑space‑per‑bedroom ratio. Deputy City Attorney Corinne Newford confirmed the 30‑day minimum rental requirement in the draft applies to newly constructed companion units going forward, not to existing units.

Councilmembers expressed competing priorities. Supporters noted San Diego's housing shortage and said many neighborhoods can accommodate modest infill; critics argued the rule could be exploited by short‑term rental operators and erode local character. Councilmember Sherman moved adoption; Councilmember Alvarez seconded. The ordinance passed 8–1, with Councilmember Keith recording the lone no vote.

The ordinance’s immediate effect is to amend city code language governing companion and junior units; staff said further design and implementation details, including parking exemptions and coastal‑zone permit requirements, will be clarified through the development services process. The council directed staff to continue outreach and to address concerns raised by community planning groups.

The council will also post the ordinance and associated implementation guidance on the city website; any specific projects under the new rules will still require whatever additional permits (for example, coastal development permits) are applicable.
