Initial analysis

The two-unit residential building at 431 Monterey Blvd in the Sunnyside neighborhood, owned by Samuel and Catherine Luk, has experienced several significant events since its construction in 1987. Most notably, in October 2024, there were allegations of unpermitted construction work involving wall demolition, sheetrock installation, and electrical work, with concerns about the conversion of a dining room into an unauthorized bedroom. The property has a concerning history of safety and compliance issues, including a substantial fire incident in August 2020 that required $85,000 in repairs to the second floor, followed by reroofing work in October 2020 costing $12,000. In 2021, an active complaint was filed regarding an unpermitted ground floor dwelling unit, leading to a December 2021 permit filing for its removal, though this issue appears to remain unresolved as of the latest planning record status.

The building has faced multiple building code violations in 2022 related to stairway safety, repairs needed for damaged ceilings and walls, plumbing issues, and a sliding glass door. These violations were addressed through various permits, including a $5,000 permit in late 2022 for installing a new partition and door. Recent complaints in 2024 suggest ongoing concerns about construction practices and permit compliance. The property has also experienced recurring issues with sidewalk parking violations, as documented in multiple 311 calls, and there have been some maintenance concerns addressed through city services, including trash collection and tree maintenance in 2023. The building's documented history shows a pattern of code compliance challenges and reactive rather than preventive maintenance responses, particularly regarding unauthorized unit conversion and construction work.

Risk rating

How 431 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

Out of 129 buildings in this neighborhood, 83 are predicted to be safer.
