Initial analysis

The 6-unit multi-family residential building at 1386-1388 9th Avenue, constructed in 1923, has undergone several significant improvements and faced some noteworthy challenges over the past two decades. Most recently, in 2023, the property demonstrated a commitment to safety by upgrading its fire alarm system to comply with San Francisco Fire Code requirements, which included installing low-frequency sounders in sleeping areas and updating all existing devices. The building has experienced recurring fire safety issues, particularly in 2020, when multiple violations were recorded relating to blocked exits, sprinkler systems, and exit maintenance, though these were subsequently abated. A substantial portion of the building's history involves various unit renovations, including a major 2009 remodeling project of the 2nd floor Unit #3 that involved extensive kitchen and bathroom upgrades, and more recent kitchen improvements in Unit #2.

The property's maintenance record shows attention to both residential and commercial spaces, with improvements made to a ground floor restaurant area in 2009-2010, including kitchen renovations and awning installations. Historical data from 2002-2005 reveals several building violations that were promptly addressed, including issues with fire escape maintenance, electrical conduits, stairs, and weatherproofing on siding. The building's most recent permits (2023) indicate active management of fire safety systems, while earlier permits show regular maintenance and improvements to various units and common areas. The property has maintained active commercial use as a restaurant, with appropriate permits obtained for ABC Type-41 alcohol service. Recent 311 calls in 2022-2024 have primarily concerned external issues such as street cleaning and sign repairs, with no recent building-specific complaints recorded.

Risk rating

How 1386-1388 9Th 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 1493 buildings in this neighborhood, 1284 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 51.4%
Moderate concern 31.7%
Severe concern 16.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
