Initial analysis

Located in San Francisco's Noe Valley neighborhood, 226 27th Street is a three-story, 10-unit multi-family residential building constructed in 1963 and owned by Peter Catalanotti. The property has undergone significant renovations and maintenance over the past decade, with the most recent work being a complete reroofing project in November 2023 valued at $23,800. Between 2012-2013, substantial improvements were made including plumbing upgrades, window replacements, kitchen remodels in units 5 and 10, and electrical system upgrades. The building faced several serious issues between 2007-2010, including unauthorized remodeling work violations in multiple units, fire safety concerns regarding fire escapes and combustible materials, and problems with rainwater piping. These violations were ultimately resolved, with the last major issue being a hazardous materials complaint in October 2023 that was corrected by December 2023.

The building's maintenance history shows regular upkeep, including exterior resealing work in 2017, window replacements in 2015, and various plumbing and electrical improvements. Planning records indicate a proposal to replace the building's rear fire escape with a new stairway, though there has been previous discussion about legalizing an 11th unit which was ultimately disapproved. The property has a history of parking-related complaints and 311 calls regarding various maintenance issues, which are common for multi-unit buildings in San Francisco. A tenant buyout occurred in January 2024, resulting in one tenant leaving the property with an $18,000 payment. The building's recent history suggests improved maintenance practices, with fewer recurring violations or complaints in recent years compared to the earlier period of significant code enforcement activity between 2007-2010.

Risk rating

How 226 27Th 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 1879 buildings in this neighborhood, 1729 are predicted to be safer.
