Initial analysis

The two-unit residential building at 630-632 Anza Street in the Lone Mountain neighborhood is a two-story flats and duplex structure built in 1932 and currently owned by Zhu Investment Group LLC. The property has undergone several significant improvements over the past decade, with the most recent being a complete reroofing project in March 2022 costing $11,000. A major renovation occurred between 2013-2014, involving substantial modifications including the removal of a light well, basement remodeling to add a kitchen and dining room in Unit #1, and the installation of new electrical infrastructure with one 200-amp service and three meters. This renovation also encompassed the addition of new bathrooms in both units, skylight relocation, garage door replacement, and comprehensive plumbing upgrades including two kitchens and bathrooms. The building had a series of violations documented in June 2002 related to safety and maintenance issues such as handrail requirements, window repairs, egress obstruction, and fire safety concerns, though all these violations were successfully abated by December 2002.

More recent complaints and service requests have primarily involved external issues such as street cleaning, parking enforcement, and occasional graffiti concerns, rather than building-specific problems. Three instances of illegal parking and one glass hazard were reported in 2024, along with various other municipal service requests throughout 2022-2023. The building's maintenance history suggests a well-managed property since the major renovations, with no active building violations or complaints regarding the building's internal conditions in recent years. The property's record indicates regular upkeep of major systems, with significant investments in both structural and aesthetic improvements, particularly during the 2013-2014 renovation period which totaled approximately $130,000 across multiple permits.

Risk rating

How 630-632 Anza 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.
