Initial analysis

The 1275 Bay Street property is a 4-unit, 2-story multi-family residential building located in the Marina neighborhood, owned by Herbert Alexandra Maclean and constructed in 1924. The building has undergone several significant safety and infrastructure improvements in recent years, most notably the complete fire alarm system replacement in April 2023 to comply with current fire code requirements, including low frequency sounders, following prior fire system upgrades in 2015. The building received substantial roof maintenance with a $40,800 reroofing project completed in 2018, and in 2016-2017 underwent voluntary structural strengthening work, including electrical and plumbing upgrades to the roof, though an initially proposed roof deck project was canceled. Multiple unit improvements were completed between 2013-2016, including bathroom remodels, electrical upgrades, and plumbing improvements such as the installation of earthquake gas shut-off valves and replacement of various heating systems.

The building's maintenance history shows regular upkeep of essential systems, including multiple HVAC system updates, electrical panel replacements, and bathroom renovations. Historical violations and complaints from 2000-2006 primarily related to heating system performance, fire extinguisher maintenance, and egress obstruction, all of which were promptly addressed and resolved. More recent fire inspections in 2012-2014 raised minor issues regarding combustible materials and alarm systems, which were also corrected promptly. The property has maintained good compliance with housing codes in recent years, with no active violations on file since 2006. While there have been numerous parking enforcement issues in the immediate vicinity of the building during 2023-2024, these relate to street parking and driveway access rather than building maintenance or safety concerns.

Risk rating

How 1275 Bay 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
34th percentile

Out of 988 buildings in this neighborhood, 652 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.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

12-Month severity forecast
No violation 63.1%
Moderate concern 13.7%
Severe concern 23.1%
