Initial analysis

The property at 36-52 Calhoun Terrace in Telegraph Hill, managed by Sanger Calhoun Terrace LP, is a multi-family residential building that has experienced various maintenance and safety issues over recent years. The most significant recent concern was a September 2021 complaint about dry rot, decay, and possible termite damage on balcony railings and siding, which required repairs to comply with a Notice of Violation. The building has undergone several window-related issues, with repairs completed in 2020 and 2021, including work on an internal metal-framed sliding glass window. Other maintenance activities included balcony repairs in 2021, bathroom remodeling in 2020, and deck repairs in 2009. The building's heating system received an update in 2010 with the installation of a new domestic hot water boiler.

Multiple housing violations were recorded in January 2019, including issues with garbage receptacles, window functionality, and light switch covers, all of which were resolved within a few weeks. There were also complaints about electrical problems, including a hot light fixture, and window-related concerns in 2019-2020. A concerning pattern of unpermitted construction activities was reported in October 2020, with allegations of unauthorized modifications to the unit. Historical issues include various fire safety violations between 2008 and 2024, primarily related to maintenance requirements for the fire alarm system, standpipes, and extinguishers at a nearby Union Street address. The building has experienced multiple false fire alarm incidents, though none resulted in civilian injuries. Recent maintenance records indicate ongoing attention to windows and structural elements, though some deductions about the building's current condition can be made from the pattern of repairs and violations.

Risk rating

How 36-52 Calhoun Ter'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

Lower risk — safer than most nearby

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
2ndpercentile

Out of 684 buildings in this neighborhood, 670 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
