Initial analysis

The 15-unit, 3-story multi-family residential building at 174 20th Avenue, owned by Dunmore Associates, has undergone significant renovations and improvements since 2018. The property, classified as a Tier 2 soft-story building, completed its mandatory seismic retrofitting under the California Soft Story Program. Recent substantial upgrades include a comprehensive electrical panel upgrade project scheduled for January 2025 across multiple units (103, 202, 203, 302, 303, 305), following previous improvements to the electrical systems in various units between 2018-2023. The building has seen consistent unit modernization efforts, with multiple apartments receiving kitchen and bathroom renovations, including unit 305 in early 2023, and structural modifications such as bearing wall removals.

The building's safety systems have been a focus of attention, with a new fire alarm system installed in 2019 (per ordinance 165-16) and subsequent upgrades to emergency lighting systems following a violation notice. Two minor fire incidents were recorded, involving a carbon monoxide detector activation (no CO detected) and a malfunctioning alarm system, with no civilian injuries reported. Regular maintenance has included addressing structural issues such as stucco repairs and dry rot remediation in 2018. While there have been several 311 calls regarding the property's surroundings, most relate to external issues like parking and street cleaning, with few pertaining directly to the building itself. The property has maintained compliance with housing inspection requirements, with routine inspections showing no significant ongoing violations.

Risk rating

How 174 20Th 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.

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.

Property class (A15)

The assessor's property-class code, which correlates with building type and the violation rates the model expects.

12-Month severity forecast
No violation 40.1%
Moderate concern 44.9%
Severe concern 15.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
