Initial analysis

845 Waller Street is a three-story, 4-unit multi-family residential building constructed in 1927, currently owned by Waller St Apts LLC. The property is undergoing significant modifications, including ongoing work as of December 2024 for the addition of three accessory dwelling units (ADUs) and related infrastructure improvements, following earlier permitted work in 2020 that aimed to convert garage spaces and perform seismic retrofitting. The building has a history of addressing various structural and safety improvements, including window replacements in 2016 (10 street-facing windows) and bathroom renovations, as well as addressing dry rot issues in 1996.

Of particular concern is the building's current non-compliant status in the Mandatory Soft Story Retrofit Program (Tier 4), with violations filed in December 2022 for failing to complete required seismic improvements. The property has experienced several safety-related incidents, including a chimney fire (date unknown) and a smoke detector malfunction, though neither incident resulted in civilian injuries. Previous violations from 2002 included multiple safety issues such as stairs repairs, fire escape obstructions, and security concerns, though these were ultimately abated. The building has undergone various routine inspections over the years, most recently in 2018, and has faced some unauthorized construction questions regarding exterior decks.

Risk rating

How 845 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
