Initial analysis

The property at 168-170 Grattan Street is a two-unit, two-story multi-family residential building constructed in 1912, currently owned by Raymond and Lauren Soriano. The building has undergone several significant improvements over the past decades, with the most substantial renovations occurring between 2007 and 2012. In 2012, major updates included a kitchen remodel with new cabinets, electrical upgrades, and bathroom improvements costing $24,000. Earlier in 2007, the building received moisture barrier and vinyl siding installations on multiple walls, both in the front and back of the structure, at a cost of $20,000. Other notable improvements included a furnace replacement in 2010, electrical repairs in 2006, and historical updates such as window installations in 1988 and reroofing in 1997.

More recently, the property has experienced several maintenance and safety-related issues. Between 2020 and 2024, there have been multiple incidents of graffiti, including some classified as offensive, with the most recent instances occurring in early 2024. There have also been two recent parking enforcement issues in February 2024. The building's fire safety record shows three alarm-related incidents over the years, though none resulted in injuries or property damage, consisting of two false alarms and one smoke detector malfunction. The street-facing areas around the property have required attention to various issues, including litter management and street cleaning, with cases being resolved by city services. While many of the building's historical permits have expired, the most recent permits and 311 calls suggest ongoing attention to maintenance and occasional neighborhood-related challenges.

Risk rating

How 168-170 Grattan 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.
