Initial analysis

The property at 450-454 Page Street is a three-unit, three-story multi-family residential building constructed in 1900, currently owned by Mb Page Street Llc. The building has experienced several significant maintenance and safety issues over the past few years, with the most recent being a series of violations and complaints in 2020 that required multiple repairs to address various safety concerns. These included problems with water heater venting, electrical fixtures, and heating systems, which were ultimately resolved through proper permits and repairs completed by early 2021. Notably, there were serious water intrusion and mold issues reported in May 2020 affecting a bedroom, though this was addressed through subsequent roof work costing $30,000 completed in 2020.

The building has a documented history of stair-related safety concerns, with multiple repairs to front and rear stairs recorded between 1987 and 2020. In 2002, serious safety violations were recorded regarding combustible storage, egress obstruction, and various electrical and plumbing issues, though these were all abated by October 2003. The property has had routine housing inspections over the years, with the most recent significant complaints occurring in 2020. While there have been two fire-related incidents on record (one cooking fire and one false alarm), neither resulted in civilian injuries. Recent external concerns reported through 311 calls between 2024 and 2025 have primarily related to street cleaning and parking issues, rather than building safety concerns, suggesting improved maintenance of the property itself in recent years.

Risk rating

How 450-454 Page 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 1027 buildings in this neighborhood, 616 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.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

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 24.7%
Moderate concern 38.5%
Severe concern 36.8%
