Initial analysis

The two-story multi-family residential building at 391-399 27th Street in Noe Valley, owned by the Denise Morgan Trust, consists of 4 units and was constructed in 1924. The property has undergone several significant repairs and improvements over the years, most notably in 2005 when work was completed to repair and replace exterior back stairs at a cost of approximately $10,000. A gas house line extension was completed in 2014. Currently, there is an active complaint (filed August 2021) regarding unpermitted construction work on the back staircase, including new framing, landings, stringers, railings, and posts, which has raised concerns about the building's structural integrity. This violation process has included a Notice of Violation in August 2021, a Final Warning Letter in October 2021, and is currently pending a director's hearing that was scheduled for July 2022.

The property has a record of routine housing inspections in 1999, 2008, and 2017, all of which were completed without any noted ongoing concerns. While there have been numerous 311 calls regarding parking violations and some maintenance issues (garbage/debris and graffiti) in recent months (between June and December 2024), these appear to be related to public street and sidewalk conditions rather than the building itself. The only significant historical building maintenance work on record prior to 2005 and 2014 was a reroofing project completed in 1991.

Risk rating

How 391-399 27Th St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
