AI summary

The three-story mixed-use building at 923-927 Pacific Ave in Nob Hill, constructed in 1916, contains three residential units with ground floor commercial space. The property has undergone several significant transformations over the years, notably including attempts to convert the ground floor commercial space to a residential ADU in both 2020 and 2022, though the 2022 permit status remains filed as of the latest update. In 2008, substantial improvements were made to the ground floor, including the construction of new living spaces (bathroom, study room, family room) and mechanical upgrades (furnace installation and electrical meter replacement), along with stair replacement work. The building has experienced several compliance issues, particularly in 2018-2019, including violations related to a vacant commercial storefront (abated February 2019) and safety concerns about fire escape stairs and corridors (abated April 2018). A troubling complaint from December 2018 raised concerns about unauthorized living conditions in one unit, citing missing windows and fire alarms, though this complaint is listed as not active. The property has generated numerous 311 calls in recent months (2023-2024), primarily related to garbage and debris issues, with multiple reports of abandoned waste and missed collection services. Historical records show earlier modifications including a change from a sewing factory to a restaurant in 1988, followed by kitchen equipment installations.

The building's record shows a pattern of attempted conversions between commercial and residential uses, with the most recent attempts focusing on creating an additional dwelling unit from commercial space. While many historical violations and complaints have been resolved, the frequency of recent waste management issues (as evidenced by multiple 311 calls) suggests ongoing maintenance challenges. The property has maintained active permits for various improvements over the years, including plumbing and electrical work, most of which has been completed satisfactorily according to permit records.

Risk rating

How 923-927 Pacific 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
80th percentile

Out of 1125 buildings in this neighborhood, 225 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Property class: apartment building

Apartment building — this property classification influences expected violation rates.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 70.0%
Moderate concern 23.9%
Severe concern 6.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
