AI summary

The 12-unit, 3-story multi-family residential building at 3720 Fillmore Street, owned by Del-camp Investments Inc, has undergone significant upgrading over the past several years, particularly in its life safety systems. Most notably, in 2023, the building received a comprehensive fire alarm system upgrade (cost: $36,741) to comply with San Francisco Fire Department requirements, followed by an as-built modification in September 2023 that relocated various alarm components to centralize safety equipment near the main entrance. This upgrade included the installation of low-frequency sounders in sleeping areas to meet current safety standards. The building has seen substantial unit improvements, with multiple apartments receiving modernizations between 2014-2021, including complete kitchen and bathroom remodels in Units 102, 203, and 301, along with electrical rewiring upgrades and the addition of new appliances and fixtures. A significant voluntary strengthening project was completed in 2015 (cost: $50,000).

The property's maintenance history shows regular attention to building systems and infrastructure, with multiple plumbing and electrical upgrades completed in conjunction with unit renovations. Recent exterior and surrounding area management includes resolutions to various urban maintenance issues such as tree management (with multiple reports in 2021-2022) and sidewalk cleaning. The building has experienced several fire alarm system complaints/notifications over the years, primarily in 2008 and 2011, all of which were resolved promptly, with the most recent incident in June 2023 being corrected within a week. The property's violation history is minimal, with only one fire safety-related violation recorded in 2006 that was promptly addressed within two months. Recent 311 calls (2022-2024) primarily relate to external issues such as parking concerns and tree maintenance, rather than building-specific problems. The property's systematic approach to unit improvements and life safety system upgrades suggests ongoing commitment to maintaining and improving resident safety and comfort.

Risk rating

How 3720 Fillmore 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

29th percentile

Out of 988 buildings in this neighborhood, 701 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.

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 location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

12-Month severity forecast

No violation 30.1%

Moderate concern 52.8%

Severe concern 17.1%

Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
