Initial analysis

The two-unit residential building at 1777-1779 Hayes Street in Park North is a two-story flats and duplex structure built in 1905, currently owned by Bob Bjorkland and De Perfetto. The building's maintenance history shows several significant repairs and improvements, most notably in the late 1980s when various projects were undertaken including reroofing, removal of kitchen light-well windows, plaster ceiling repairs, and voluntary safety structural reinforcement. In 2003, deck and railing repairs addressing dryrot issues were completed. A notable complaint about the property was filed in 2004 regarding the suspected illegal addition of a third unit, though this issue was eventually abated in 2009.

The most pressing recent concern for the building has been recurring sewer issues, with three documented sewage backup incidents in 2021-2024, and one in late 2019 that revealed issues with the lower lateral line and curb face drop. Other maintenance matters have been relatively minor, including a damaged tree removal in 2020, some graffiti incidents (resolved by city crews), and periodic issues with traffic and parking enforcement. While the building has an extensive history of repairs and maintenance, particularly in the late 1980s, the repeated sewer issues in recent years represent the most significant ongoing infrastructure concern. The property has demonstrated regular attention to maintenance and repairs, with most city service calls being resolved promptly through proper channels.

Risk rating

How 1777-1779 Hayes 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 797 buildings in this neighborhood, 223 are predicted to be safer.
