Initial analysis

The 11-unit, 3-story apartment building at 170 Duboce Avenue in Mission Dolores, owned by Podolsky John Rev Living Trust, was constructed in 1912 and has undergone several significant improvements over the past two decades. Most notably, the building completed mandatory seismic strengthening work in 2014 under the soft-story ordinance, which included plywood and anchor bolt installation at the garage level, with the work receiving a Certificate of Final Completion. The building has undergone extensive unit improvements, including multiple kitchen and bathroom remodels, window replacements, and plumbing upgrades. Recent maintenance issues have surfaced, including a 2023 fire violation related to the alarm system that was referred to hearing, and recurring concerns about boiler permit renewals between 2017-2020, suggesting some ongoing maintenance oversight. Historical fire safety violations from 2004 (related to fire escape maintenance, combustible storage, and fire proofing) were all abated, and there have been no active fire safety violations since then. The building's maintenance record shows regular attention to unit upgrades and building systems, though recent complaints about gas utility shutoff tools and fire extinguisher maintenance requirements in 2022-2023 indicate some areas needing ongoing attention. The property has experienced routine garbage and debris issues in recent months, as evidenced by multiple 311 calls in 2024, though these appear to be street-related rather than directly tied to building management.

Risk rating

How 170 Duboce 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
13th percentile

Out of 799 buildings in this neighborhood, 695 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.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

12-Month severity forecast
No violation 39.2%
Moderate concern 30.5%
Severe concern 30.3%
