Initial analysis

The two-story, six-unit apartment building at 3701-3709 16th Street in Corona Heights, constructed in 1907, has experienced several maintenance and safety-related issues over its recent history. Most notably, there is currently an active routine inspection complaint from June 2021 that remains unresolved, which includes multiple fire safety violations such as egress obstruction, gas meter instructional diagram requirements, gas utility shutoff tool provisions, and garbage receptacle placement issues. The building underwent significant plumbing and safety improvements in recent years, including the installation of fire sprinklers in the garbage area in 2021, wall heater replacement in 2022, and previously completed gas houseline extensions in 2012. Structural repairs have been a recurring theme, with work on stairways in 2010 (including wooden stairs to the roof and front exterior stairway repairs) and dry rot repairs in 2002, though a concerning complaint from 1998 about unauthorized rooftop occupation and safety issues was filed but subsequently closed.

The property has maintained some infrastructural updates over the years, including an electrical underground service conversion in 2005, though older permits from 1990-1991 for reroofing are now expired. While there have been multiple 311 calls regarding the property's vicinity, these generally relate to external issues like graffiti, street cleaning needs, and transportation matters rather than direct building concerns. A false fire alarm incident was recorded with no civilian injuries reported. The building's maintenance history shows regular attention to safety requirements, though the ongoing 2021 violations and the historical 1998 rooftop incident highlight areas of past and potential continuing concern regarding resident safety and building management responsiveness.

Risk rating

How 3701-3709 16Th 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.
