Initial analysis

The three-unit, three-story multi-family residential building at 538-542 Waller Street in Hayes Valley, built in 1904 and currently owned by Gflats LLC, has undergone significant renovations and improvements over the past decade. In 2015, the entire building received major updates including a comprehensive electrical rewiring, new furnaces for all units, and extensive plumbing work featuring tankless water heaters, bathroom and kitchen renovations across all units. Two separate bathroom additions were completed in 2015, with associated costs totaling over $85,000 and work including kitchen remodeling, laundry facilities, and gas line installations. A notable incident occurred during this renovation period in September 2015, with two complaints filed regarding suspected sewage leaks during construction, though these complaints were marked as "Not Active."

The most recent permitted improvements, filed in March 2016, involved basement renovations and garage creation, though the status remains "Filed." The building experienced one documented cooking-related fire incident, though it was contained with no civilian injuries reported. More recently, in 2024, there have been multiple reports regarding street-level issues near the building, including several cases of garbage and debris, abandoned furniture, and driveway-blocking vehicles, though these are not directly related to the building's condition or management. The property was the subject of two tenant buyouts in October 2015, with payments of $88,292.50 and $76,981.35 to four and five tenants respectively, suggesting significant changes to the building's occupancy during that period. Recent plumbing infrastructure work has included attention to the side sewer vent cover, with the most recent work being completed in October 2024.

Risk rating

How 538-542 Waller 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
57th percentile

Out of 1027 buildings in this neighborhood, 442 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.

Neighborhood location

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

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

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 58.3%
Moderate concern 20.8%
Severe concern 20.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
