Initial analysis

The three-unit residential building at 433-437 Waller Street in Hayes Valley, owned by the William Maher 2014 Revocable Trust, is a three-story flats structure built in 1900. The property has undergone several significant improvements over the past two decades, including multiple compliance updates. In 2017, the building addressed requirements from physical inspection report #CC-8151, and in 2015-2016, heating and electrical systems received attention with the installation of new heaters, electrical outlets, and safety upgrades to the electrical panel. Earlier renovations from 2004-2006 included kitchen remodels in multiple units, bathroom improvements, and the installation of vinyl siding to the building's rear.

The building's maintenance history shows consistent attention to safety and compliance issues, including two fire safety inspections in 2016 and 2018 that required corrections to fire extinguishers and alarm systems. While the property has had some historical building complaints from the 1990s regarding electrical wiring and water damage, these issues were resolved. Recent incidents have primarily involved external maintenance matters, including a 2023 sewage vent issue and several parking-related complaints. Three units were previously converted to condominiums, and the building has maintained its multi-family residential classification. Recent permits and service requests indicate ongoing maintenance attention, particularly to heating, electrical, and safety systems.

Risk rating

How 433-437 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

Out of 1027 buildings in this neighborhood, 534 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 age

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

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 51.1%
Moderate concern 20.2%
Severe concern 28.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
