Initial analysis

The property at 591 Monterey Blvd in the Sunnyside neighborhood is a 2-story, flat & store multi-family residential building constructed in 1980, containing 2 residential units and owned by Lei Lai Kun. The building has experienced several significant issues over its history, most notably ongoing concerns regarding unauthorized unit conversions and maintenance problems. The most recent developments include bathroom fixture relocations in 2022 and 2023, and a completed project in 2020 to restore approved floor plans following a Notice of Violation. A notable complaint from 2017 reported persistent water leakage issues resulting in mold problems, while earlier complaints from 2004-2006 indicated serious electrical hazards, plumbing violations, and unauthorized unit concerns that were eventually addressed but took years to resolve.

The building underwent multiple substantial renovations and repairs between 2009-2022, including ADA compliance work, reroofing in 2012, and various bathroom renovations. Several fire safety violations were recorded in 2009-2011 related to fire extinguishers and exit access, all of which were subsequently addressed. The property's history includes some concerning habitability issues, such as a 2010 complaint regarding lack of heat, unfinished kitchen cabinets, and various maintenance problems, though these issues were later resolved. Planning records show an application for unit legalization that was withdrawn in 2024, with the determination that the ground floor unit had no legal path to legalization under current regulations. The building has been the subject of various 311 calls in 2024 primarily related to street maintenance and cleaning issues, though these are external to the building itself.

Risk rating

How 591 Monterey Blvd'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.

Neighborhood percentile
