Planning Commission approves controversial Grove Street infill after fire‑safety review and conditions

The Planning Commission approved a conditional‑use authorization and associated variances for a four‑unit infill at 1846 Grove Street after prolonged neighbor opposition and a review of life‑safety issues.

The project—revised from five units to four—was presented to the commission with design changes intended to reduce massing and privacy impacts on adjacent yards. Staff noted the lot’s flag shape and recommended approval with conditions. Neighbors opposed the project in large numbers on record, citing a narrow 3.5‑foot access corridor, the lack of service access, proximity to rear lot lines, potential loss of backyard and privacy, and concerns about emergency response during fire or earthquake.

The sponsor made several changes after earlier hearings and provided retired San Francisco fire captain Mario Ballard to explain the department’s review. Ballard said the plan had been reviewed by engine, ladder and division chiefs, that the buildings will be fully sprinkled and that dedicated on‑site hydrants, upgraded construction type and a robust sprinkler design were part of the life‑safety approach. "These buildings are sprinkled and the fire department has reviewed feasible access and hydrant placement," he said.

Commissioners requested a specific condition: if life‑safety reviews or permit review require significant design changes, those changes must return to the Planning Commission for a new conditional use authorization. The commission also approved standard variance conditions and other site controls to address construction sequencing and noise mitigation.

The final motion — moved and seconded by commissioners supportive of the project — carried unanimously (6–0). Commissioners stressed that the approval is conditioned on final DBI and fire‑department plan review and that any material changes to life‑safety provisions would trigger an additional commission review.
