Initial analysis

The two-story multi-family residential building at 2700 20th Street in the Inner Mission was built in 1900 and contains four units, currently owned by John Y & Jeannie Wong. The building has undergone some recent maintenance work, most notably a $20,000 reroofing project that was completed in October 2023, demonstrating ongoing property upkeep by the current owners. Historical violation records show that in September 2003, the building faced multiple safety-related issues, including problems with fire escape drop ladders, handrails, and security viewer installations - all of which were successfully abated by October 17, 2003. Since that time, there have been no recorded building violations or major safety concerns, indicating improved maintenance standards in recent years.

The property has had routine inspections in 2003 and 2009, both of which were resolved. While there have been several 311 calls regarding the property's vicinity in recent years (2023-2025), most relate to street-level issues such as parking violations and sidewalk conditions rather than building-specific problems. The most recent maintenance activity, the 2023 reroofing project, suggests proactive maintenance by the owners. The building's only recorded fire incident was a malicious false alarm related to telephone service, with no injuries or damage reported. The property's maintenance record shows no pattern of recurring issues, and the significant time elapsed since the last building violation - combined with the recent roofing work - suggests that the property is being properly maintained under current ownership.

Risk rating

How 2700 20Th St'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 2380 buildings in this neighborhood, 738 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.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

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 52.1%
Moderate concern 32.0%
Severe concern 15.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
