Initial analysis

The 451 Hyde Street building is a 3-story, 7-unit multi-family residential structure built in 1909, currently owned by the Naguit Family Rev Intervivo. The property has undergone several significant improvements over the years, including a $60,000 seismic retrofit of unreinforced masonry in 2001, reroofing projects in 1989 and 2016, and the legalization of a basement residential unit in 2015 at a cost of $45,000. Recent maintenance includes plumbing updates in Unit 1 and electrical work in 2017, though some electrical work was cancelled. The building has experienced recurring maintenance and safety issues, particularly between 2012-2014, including violations related to heating system failures, appliance malfunctions, and unauthorized construction work in Unit 5. These violations, while placed in the "Not Active" category, suggest historical challenges with building systems and unit maintenance.

Recent history shows ongoing building and neighborhood maintenance activities, with multiple 311 calls in 2023-2024 related to general cleaning, graffiti removal, and waste management in the Tenderloin area. A notable incident occurred in May 2018 involving bed bugs and a broken door lock, though this issue was resolved within two months. The building's management has addressed several major maintenance items over the years, including the renewal of boiler permits in 2015-2016, though a 2017 electrical rewiring project was cancelled. External factors such as street cleaning and graffiti removal continue to be addressed through regular municipal services, as evidenced by numerous 311 calls for street and sidewalk cleaning assistance in recent years.

Risk rating

How 451 Hyde 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
90th percentile

Out of 172 buildings in this neighborhood, 17 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 26.2%
Moderate concern 24.5%
Severe concern 49.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
