Initial analysis

The property at 2728-2734 San Bruno Ave in the Portola neighborhood is a 3-story multi-family residential building constructed in 1959, containing 10 units and classified as an Apartment building with 5 to 14 units. The building has undergone several significant modifications and improvements over recent years, most notably completing its mandatory soft-story seismic retrofit requirements as a Tier 4 building with a Certificate of Final Completion issued. The property has seen recent commercial modifications, including the conversion of a garage to storage space and installation of restaurant equipment, though not without some complications, as evidenced by the July 2024 revision to remove walk-in refrigeration equipment from the project scope. The building has experienced various maintenance issues requiring attention, particularly between 2019-2022, including problems with heating systems, kitchen appliances, and multiple complaints regarding fire safety equipment such as extinguishers and sprinkler systems.

The property has a history of fire safety violations and complaints, with significant clusters of issues in 2016-2017 related to combustible materials, alarm systems, and housekeeping that were ultimately abated. More recent fire safety concerns were addressed in early 2023 regarding extinguishers and sprinkler systems. The building's maintenance history includes multiple plumbing and electrical upgrades, such as water heater replacement and electrical system improvements. Recent months have seen recurring issues with graffiti and exterior maintenance as evidenced by multiple 311 calls between 2023-2024. A notable concern emerged in 2021 regarding unapproved exhaust hood equipment and a questionable walk-in installation in the garage area, which remains an active building inspection case as of the last available update. The property has maintained active compliance with major safety requirements, including completion of the soft-story retrofit program, though historical records show periodic lapses in maintaining fire safety equipment and systems.

Risk rating

How 2728-2734 San Bruno Ave'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 255 buildings in this neighborhood, 240 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.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

12-Month severity forecast
No violation 12.7%
Moderate concern 36.9%
Severe concern 50.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
