Board upholds permit for tiny‑house at 1230 Guttingen St., denies neighbor appeal

The San Francisco Board of Appeals voted 4–0 on Feb. 21 to deny an appeal by Jacqueline Matherne of the site permit for 1230 Guttingen Street (permit number 20219238995).

Appellant representative Kathy Gower told the board the lot is “ill conceived,” calling the proposed two‑story dwelling too small for a family and pointing to privacy, set‑back and circulation issues; she said neighbors who had initially supported the project withdrew their support after seeing revised plans. Neighbors who spoke at the hearing cited concerns about construction dust, potential health impacts for nearby residents and privacy from the rooftop open space.

The permit holder and project team said the design followed previous board directions: the project was scaled back from three stories to two and conforms to conditions the Board of Appeals imposed during a 2021 variance proceeding. Tina Tam, deputy zoning administrator, told commissioners the current plans are consistent with the board’s 2021 design changes and that the lot is a legal lot of record. DBI and planning staff said the application had been reviewed by multiple departments including fire, public works and PUC.

Commissioners noted the long history: the variance and design changes were previously considered and, while some members expressed qualms about neighborhood character and the project’s scale, they said the appeal did not identify legal errors or new evidence that would overturn the permit. Commissioner J. R. Epler moved to deny the appeal; the motion passed 4–0.

Outcome: appeal denied; permit remains in effect. Commissioners urged permit holder to work with neighbors on dust mitigation and other construction‑phase concerns.
