Initial analysis

The six-unit multi-family residential building at 1630 Filbert Street in Cow Hollow, owned by the Helen L Lowe Revocable Trust, has undergone several significant improvements since its construction in 1950. Most notably, in early 2021, the building received a comprehensive fire safety upgrade with the installation of a new fire alarm system, including sprinkler monitoring, low-frequency sounders in all units, and horn-strobe sounders in common areas, with the work being completed at a cost of $32,314. The building completed its soft-story seismic retrofit in 2018 (Tier 4), demonstrating compliance with San Francisco's earthquake safety requirements. In 2019, two units (1 and 5) underwent substantial renovations including kitchen and bathroom remodels, addition of washer/dryer facilities, with work values totaling $93,000, and this was supported by both plumbing and electrical permits.

The property has maintained active compliance with safety regulations, though there was one building complaint in 2012 regarding unauthorized construction work that was resolved within two months. Historical violations from 2002, primarily related to fire safety and security, were all abated by May 2002. The building has undergone various infrastructure improvements, including electrical modifications, plumbing upgrades, and multiple street space permits over the years. Recent records from 2021-2024 show several parking-related complaints, primarily for blocked driveways, which have all been addressed through citations, though these are external to the building's operations. A recent permit from September 2024 indicates street space usage, though the specific nature of this permit is not detailed in the records.

Risk rating

How 1630 Filbert 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.

Neighborhood percentile
43th percentile

Out of 861 buildings in this neighborhood, 491 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

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

Building size

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

Property class: multi-family flat

2–4 unit flats (class F) are a common SF building type with their own maintenance and complaint patterns.

12-Month severity forecast
No violation 58.7%
Moderate concern 20.0%
Severe concern 21.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
