Initial analysis

116 Locksley Avenue is a two-story, four-unit multi-family residential building constructed in 1961, currently owned by Cheng Conmin. The property has undergone several significant maintenance and safety upgrades over the years, with the most recent being a fire alarm system upgrade completed in March 2024 at a cost of $12,820, which included the installation of low-frequency sounders in sleeping areas to meet current safety standards. The building has experienced recurrent maintenance issues, particularly related to water and weatherproofing, as evidenced by multiple repairs to windows, siding, and light wells between 2015 and 2020. One notable incident occurred in 2013 when an unauthorized structure was built over the fire escape, which was subsequently removed under a completed permit. The building has undergone several routine inspections over the years, with the most significant cluster of violations documented in 2001, including issues with interior surfaces, electrical systems, garage ventilation, and smoke detection systems, all of which were abated by July 2001.

The property's maintenance history shows a pattern of attention to both interior and exterior issues, with regular inspections prompting necessary repairs. Recent work has focused on safety improvements, particularly the fire alarm system upgrades in 2024, indicating proactive maintenance under current ownership. The building has experienced some infrastructure challenges, as evidenced by sewer backup incidents in 2022, though these were promptly addressed. While the property has had its share of building code violations in the past, all documented issues have been resolved, and recent maintenance patterns suggest improved oversight of building systems and compliance requirements. The area around the building has experienced typical urban issues such as abandoned vehicles and graffiti, though these are external to the building itself and have been addressed through normal city channels.

Risk rating

How 116 Locksley 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
42th percentile

Out of 50 buildings in this neighborhood, 29 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.

Neighborhood location

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

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 60.8%
Moderate concern 20.1%
Severe concern 19.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
