Initial analysis

The 2-unit, 2-story multi-family residential building at 644-646 Judah Street in the Inner Sunset, owned by the Rita S Ibert 2000 Trust, has undergone significant improvements since its 1930 construction. The most substantial recent work involved the legalization and remodeling of an unpermitted ground floor unit in 2018, followed by the complete installation of a fire sprinkler system in 2019 ($11,000) with subsequent improvements in 2020, totaling approximately $18,000 for sprinkler-related work. Other major improvements include a comprehensive window replacement project in 2019 ($13,000), installation of a new furnace and water heater in 2020, and a complete re-roofing in 2016 ($18,000). The building's safety infrastructure has been notably enhanced with the installation of a sprinkler monitoring system in late 2020.

Recent maintenance work in 2024 included repairs to two gas lines, indicating ongoing attention to building systems. The property has been generally well-maintained, with no reported serious safety incidents. While there have been several 311 calls related to the property's vicinity between 2021 and 2024, these were primarily regarding street cleaning, parking issues, and environmental concerns that do not directly impact the building's condition or safety. The building's history shows regular upkeep and upgrading of essential systems, with particular attention paid to fire safety compliance and unit legalization.

Risk rating

How 644-646 Judah 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 1493 buildings in this neighborhood, 433 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.

Building size

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

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

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 83.3%
Moderate concern 12.3%
Severe concern 4.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
