Initial analysis

The three-unit residential building at 747-749 Waller Street in Hayes Valley is a three-story flats and duplex structure built in 1900, currently owned by Eric M. Keller and Emilie Kernisan. The property has undergone several significant improvements in recent years, including a major conversion in 2018-2019 that transformed 707 square feet of crawl space into habitable living space, adding new family rooms, bathrooms, and laundry facilities. More recent work includes a $19,800 reroofing project permitted in May 2024 and the replacement of seven front-facing aluminum windows in 2020. The property has experienced some construction-related issues, with active complaints from 2022 regarding work beyond permit scope and previous complaints in 2019 about construction dust, dirt, and debris.

Historical records show several building violations from 2002 and 2009, including fire safety and security issues, though all have been resolved. The building underwent plumbing work in 2013 for sewer repairs and electrical updates in 2019 to accommodate new ground floor installations. Recent maintenance issues include a missing side sewer vent cover reported in October 2024 and previous parking enforcement matters outside the building. The property has had multiple 311 calls regarding street conditions and parking enforcement in recent years, with most cases being resolved through official intervention. Two notable historical complaints were filed in 2009: one regarding unhealthy living conditions involving excessive clutter and potential fire hazards, and another concerning unauthorized tenant improvements, both of which were subsequently addressed.

Risk rating

How 747-749 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, 380 are predicted to be safer.
