Initial analysis

733-743 Waller Street is a 6-unit, 3-story multi-family residential building constructed in 1908, currently owned by Segal Living Trust. The building has undergone several significant improvements over the past decade, most notably including a solar hot water system installation in 2018 (with 4 solar collectors, 2 storage tanks, and a heat exchanger), an electrical service upgrade in 2014 (including new 200-amp main service and seven meters), and various renovation works in 2014-2016. These renovations included window replacements, kitchen remodels in units 739 and 741, bathroom updates, and the construction of a concrete retaining wall to replace a wood structure. The property has experienced some maintenance issues, with multiple reports of missing side sewer vent covers in recent years (most recently reported in October 2024), and historical concerns about stairs/deck repairs and self-closing doors from 2002-2003 that were ultimately resolved.

In 2023, the building received several compliance-related citations that were subsequently addressed, including requirements for gas utility shutoff tools and compliance affidavits. The property has experienced periodic graffiti incidents (most recently reported in 2020), and there was one documented carbon monoxide incident, though no civilian injuries were reported. The building's maintenance history shows a pattern of addressing both routine upkeep and significant upgrades, with the recent solar installation and electrical upgrades representing notable improvements to the building's infrastructure.

Risk rating

How 733-743 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.
