Initial analysis

The 12-unit, 3-story multi-family residential building at 2255 Lake Street, owned by Gruber Legacy LP, has undergone significant safety and modernization improvements since its construction in 1922. Most notably, the building achieved compliance with the Mandatory Soft Story Retrofit Program, completing work valued at $90,000 in 2017, with all associated requirements finally being signed off in 2023. Recent safety upgrades include a 2023 fire alarm system enhancement adding low-frequency sounders to sleeping areas and a new boiler installation with an 80-gallon storage tank, demonstrating ongoing commitment to resident safety. The building has a history of kitchen and bathroom renovations in multiple units between 2008 and 2017, along with electrical system improvements including new lighting, appliance installations, and smoke detector upgrades.

The property's maintenance record shows attention to fire safety systems, with multiple fire alarm-related violations and complaints being resolved promptly, including a 2024 violation that was abated. Historical issues from 2003 related to various fire safety and maintenance concerns were addressed and closed. Recent 311 calls primarily relate to external issues such as parking violations and street maintenance, rather than building-specific concerns. The building's infrastructure has been regularly updated, including a significant reroofing project in 2009 and various plumbing and electrical upgrades over the years. The most pressing current issue appears to be an open case regarding an overgrown tree as of October 2024, though this is an external property matter rather than an internal building concern.

Risk rating

How 2255 Lake 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
