Initial analysis

The property at 1434-1438 Grant Avenue in Telegraph Hill is a three-story, 11-unit multi-family residential building constructed in 1913 and currently owned by Ack LLC. The building has undergone several significant safety and infrastructure upgrades in recent years, most notably the installation of a comprehensive fire alarm system in late 2023, including low-frequency sounders in sleep areas and smoke detection in common areas, which completed a long-term fire safety improvement project that had experienced multiple violations between 2017-2024. The building has also completed its mandatory soft-story retrofit work as a Tier 4 building, with the final fire code certification issued.

Recent building improvements include the installation of new windows on the front facade in early 2024 and a new 100-gallon water heater, with historical records showing earlier HVAC system upgrades in 2014. The property has had multiple fire safety-related violations over the years, including issues with extinguishers, exits, and smoke alarms, though most have been promptly addressed and abated. Building maintenance history shows some plumbing challenges, including sewer issues in 2008 and 2019, with records indicating resolution of these problems. The building has received several noise complaints related to entertainment activities, particularly in 2024, though inspections indicated compliance with permit conditions. While there were multiple routine inspections and violations recorded between 2001-2011 related to fire safety and building maintenance, these issues appear to have been resolved through subsequent corrective actions.

Risk rating

How 1434-1438 Grant 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 684 buildings in this neighborhood, 657 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.

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 8.2%
Moderate concern 59.7%
Severe concern 32.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
