Initial analysis

The four-story, eight-unit apartment building at 1530 Green Street in Cow Hollow, owned by James M Tappe Separate Prop, was constructed in 1906 and has undergone several significant renovations and maintenance projects over its lifetime. The building has a history of fire safety-related issues, particularly concerning its alarm systems, with the most recent violations occurring in September and October 2024, as well as a Sleeping Area Requirement violation from November 2023 that is currently open. The property has shown consistent attention to major systems upgrades, with substantial work completed in 2007-2009 including electrical system upgrades, kitchen and bathroom remodels in multiple units, and the installation of new furnaces. Notably, in 2010, the building underwent voluntary strengthening work including foundation bolting and front bay window reinforcement.

The building's maintenance record shows regular upkeep of critical systems, though there have been some concerning issues recently addressed through inspections and permits. In 2015, for example, there was work done to repair a rear staircase railing, and in 2008 there was a gas pipe repair in Unit #8 that required special inspection. The property has also experienced some recent exterior maintenance challenges, with multiple reports of abandoned furniture and debris (including Christmas trees) on the property in late 2024. Historical records show the building faced multiple violations in 2001 related to fire safety systems (including alarm systems and egress obstructions), though these were all abated by November 2001. The building underwent various inspections, including routine housing inspections in 2001 and 2007, and multiple fire safety inspections over the years, with most issues being promptly corrected or showing no merit upon inspection.

Risk rating

How 1530 Green 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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

12-Month severity forecast
No violation 51.4%
Moderate concern 33.7%
Severe concern 14.9%
