Initial analysis

The property at 36 Prague Street is a two-unit, two-story multi-family residential building located in the Excelsior neighborhood, built in 1910 and currently owned by the Julio & Ana Arce Family Trust. The building's permit history spans several decades, with work completed in the mid-1980s including kitchen renovations and wall modifications, followed by siding replacement in 1995. Recent activity from early 2025 shows several concerning issues, particularly two separate sewage backup incidents from the side sewer vent in January 2025, and an ongoing excessive noise complaint. The building has experienced recurring fire safety concerns, with multiple fire complaints between 2005-2023 regarding combustible materials, weeds, and other hazards, though most were marked as "Condition Corrected." There have been three significant fire violations documented between 2008 and 2016, including issues with storage of combustibles and blocked exits, with the most recent violations occurring at nearby 251 Munich Street.

The building's recent history shows maintenance challenges, with multiple structural maintenance requests and a 2025 graffiti report still open. The property has had several 311 calls regarding parking enforcement, sidewalk cleaning, and building inspection services in January 2025. The most recent tenant buyout at a nearby property (259 Moscow Street) occurred in February 2024 involving two tenants for $10,000, though no such action has been recorded for 36 Prague Street. While the building has undergone various improvements over the years, including kitchen renovations and foundation work in the 1980s, the recent history suggests ongoing maintenance and infrastructure challenges that require attention.

Risk rating

How 36 Prague 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 337 buildings in this neighborhood, 118 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building age

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

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

12-Month severity forecast
No violation 68.6%
Moderate concern 15.8%
Severe concern 15.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
