Initial analysis

The two-story multi-family residential building at 557-559 Frederick St, owned by Papakonstantino Eugenia, is a 4-unit apartment building constructed in 1900 in the Parnassus/Ashbury Heights neighborhood. The building's inspection history reveals several significant safety violations, particularly during the early 2000s. In March 2003, multiple violations were documented, including egress obstructions, stair repairs needed, fire safety issues (such as fire extinguisher requirements and fire proofing repairs), and security concerns regarding exit door locks. These violations were addressed and abated by April 28, 2003. A 2008 routine inspection noted missing smoke detectors at the stairs and another egress obstruction. More recently, the building underwent a routine inspection in 2017, though no specific violations were recorded in the available data.

The property has experienced periodic resident concerns, including a significant complaint in 1995 regarding unsafe conditions with broken stairs, window insulation issues, bathroom tile problems, and plumbing leaks. More recent complaints include a 2016 case about construction noise affecting a resident's health. The building's recent history shows minimal internal violations but several exterior maintenance needs, as evidenced by 311 calls in 2023-2024. These include issues such as graffiti, an overgrown tree (reported as of November 2024), and various parking enforcement matters. The most recent building-related service requests involve public works and street repair matters, with several parking enforcement cases documented in early 2024. While the building has a history of safety violations, it's notable that most have been resolved, with no major internal violations reported in recent years. However, ongoing concerns about exterior maintenance and parking issues persist, as evidenced by multiple recent 311 calls.

Risk rating

How 557-559 Frederick 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
21th percentile

Out of 526 buildings in this neighborhood, 416 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 age

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

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 66.9%
Moderate concern 16.3%
Severe concern 16.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
