Initial analysis

The property at 1557-1559 11th Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Inner Sunset neighborhood, owned by the Darryl H Chew 2007 Revocable Trust and constructed in 1965. The building has undergone several significant renovations over the past few decades, with the most recent major work occurring in 2020, including a comprehensive kitchen and bathroom remodeling project costing $60,000, followed by a $14,500 foam overlay reroofing project. The building's maintenance history shows regular roof upkeep, with previous roofing work documented in 1995 and 2002. Notably, the building experienced earthquake damage in 1990 that required repairs to resolve front stucco cracks. In addition to the roofing and interior improvements, the property underwent plumbing updates in 2020, including fixture replacements and a shower pan replacement.

The building has had relatively few complaints or incidents over its history, though there was a brief investigation in 2008 regarding unauthorized construction of a large structure in the rear yard, which was resolved within two weeks. Recent external issues have primarily involved typical urban infrastructure matters rather than building-specific concerns, including two parking enforcement calls in September 2024, a utility vault repair request in June 2023, and a graffiti removal request in November 2019. Historical modifications to the property include the addition of a game room in the basement in 1985, and there are no recorded complaints or violations that would significantly impact current resident experience or safety. The building's maintenance record demonstrates regular upkeep, particularly with regard to roofing systems, which have been replaced or updated approximately every 10-15 years.

Risk rating

How 1557-1559 11Th 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

Out of 1493 buildings in this neighborhood, 15 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.

Building age

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

Neighborhood location

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

Notices of Violation, owner's portfolio

DBI NOVs across all buildings this owner is registered on — a signal of systemic maintenance issues across the portfolio.

12-Month severity forecast
No violation 93.3%
Moderate concern 5.2%
Severe concern 1.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
