Initial analysis

The property at 434-436 Waller Street is a two-unit, two-story multi-family residential building located in Hayes Valley, constructed in 1900. The building experienced a significant fire incident in July 2011 that resulted in substantial damage requiring comprehensive repairs across all systems. The fire-related repairs included the replacement of windows, wall framing, and other structural components, with initial violations documented between July 2011 and September 2011 regarding compromised roof, ceiling framing, and plumbing systems. The reconstruction phase involved multiple permits and inspections between 2012 and 2017, including a complete electrical rewire, plumbing upgrades for bathrooms and kitchens, and the installation of new fire safety systems.

Of particular note is the evolution of the rear egress stairway situation, which underwent several modifications and permit revisions between 2012 and 2015, including the installation of a new spiral stair with associated landings at each unit, as well as changes to the roofline. The building's rehabilitation included addressing various code violations and obtaining necessary variances for modifications, particularly regarding the rear yard encroachment. The most recent permit activity in 2017 involved obtaining final inspections for previously approved work. Since the completion of the major renovation work, there have been minimal building-related complaints or violations, though some recent 311 calls in 2024 have been recorded for issues such as parking violations, a missing side sewer vent cover, and various debris cleanup requests on the property. The building now appears to be in compliance with all major building codes and requirements, with no active violations on record.

Risk rating

How 434-436 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
