Initial analysis

1901 Noriega Street is an 8-unit, two-story multi-family residential building constructed in 1956 in the Central Sunset neighborhood, currently owned by Nor Apartments. The property has undergone several significant safety improvements in recent years, most notably completing a mandatory soft story retrofit in 2015 (with a cost of $83,000), which brought the building into compliance with San Francisco's earthquake safety requirements. Other important upgrades include the installation of a new fire alarm system (2017), a comprehensive fire sprinkler system in 2008, and electrical system improvements including a new service with nine meter sockets in 2005 and Ufer ground installation in 2017. The building has experienced periodic maintenance issues, particularly in the mid-2000s, including multiple violations in 2007 related to fire escape maintenance, plumbing, and general building upkeep, though most of these were abated by December 2007.

The property has maintained active engagement with building codes and safety requirements throughout its history. Earlier improvements include window replacement (2004) and various roofing work in 1991 and 1997. A notable plumbing issue from 2005 involving kitchen water damage was resolved within six months. The building has experienced minimal fire-related incidents, with the most recent being a false alarm in 2017 and two minor contained cooking fires in the past, none resulting in civilian injuries. Recent 311 calls indicate ongoing concerns with exterior maintenance, primarily involving garbage and debris on public spaces around the property, with multiple reports throughout 2024, though these are primarily street cleaning issues rather than building maintenance concerns. The building's record shows consistent attention to required safety systems and periodic address of maintenance issues, with no active violations or complaints as of the current date.

Risk rating

How 1901 Noriega 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 814 buildings in this neighborhood, 765 are predicted to be safer.
