Initial analysis

The property at 811 Alvarado St in Noe Valley is a two-story, six-unit multi-family residential building constructed in 1900 and currently owned by Michael C. Lai and Shirley Tu. The building has undergone several significant improvements over the past decades, with the most recent being a complete reroofing completed in September 2023 at a cost of $22,000. In 2016, substantial interior renovations were completed in Unit D, including bathroom and kitchen remodels with proper plumbing and electrical permits, totaling $24,000. Two major issues were addressed in the early 2000s, including a cluster of violations in late 2002-2003 regarding safety concerns such as smoke detector repairs, handrail repairs, and unauthorized modifications to walls, along with ventilation and fire safety concerns that were all abated by August 2003. A 2003 complaint about an unpermitted concrete slab installation in the rear yard was also resolved, and corresponding permits show this work was later completed properly in 2004 for $16,000.

Recent maintenance records show ongoing attention to the building's infrastructure, with the most recent work being the 2023 reroofing project. The property has experienced some recent issues as evidenced by 311 calls, including a sewage backup incident from the side sewer vent that was resolved in August 2024, and pavement defects reported in September 2024. The building has a history of parking enforcement issues in the surrounding area, with multiple driveway blocking incidents reported between 2020-2024, though these are external to the building itself. While there were some serious code violations noted in the early 2000s, the records indicate these were properly addressed and there have been no similar significant violations in recent years, suggesting improved compliance with building codes and regulations.

Risk rating

How 811 Alvarado 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
50th percentile

Out of 1879 buildings in this neighborhood, 940 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 76.4%
Moderate concern 13.8%
Severe concern 9.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
