Initial analysis

The three-story, 8-unit apartment building at 30 Rausch Street in San Francisco's South of Market neighborhood, owned by Tang/wong Fmly Tr, has undergone significant improvements and expansions since its construction in 1912. Most notably, the building added an eighth unit on the ground floor in 2017, following the legalization of a seventh unit and completion of required upgrades including a soft-story retrofit (2017) costing $45,000 to ensure seismic safety compliance. Between 2019-2021, the property invested substantially in safety and modernization improvements, including the installation of fire sprinklers ($15,000), a fire alarm monitoring system ($14,900), and two high-efficiency furnaces. The building's systems have been brought up to current safety standards, with recent permits showing attention to both fire safety and energy efficiency.

The property has a history of addressing building code requirements and safety concerns, with several completed permits demonstrating ongoing maintenance and upgrades. A notable cluster of violations was recorded in 2004 regarding staircase safety, handrails, and storage issues, but these were all promptly addressed and abated by April 2004. More recent inspections and permits show a consistent pattern of proactive maintenance and compliance with current building codes, including the installation of modern safety features such as sprinklers and fire alarms. The building's location has experienced typical urban issues as documented in 311 calls, including sidewalk maintenance and cleaning matters, though these are largely routine municipal matters rather than building-specific concerns. The property's most recent major upgrades (2020-2021) have focused on both safety systems and energy efficiency, indicating ongoing investment in the building's infrastructure and systems.

Risk rating

How 30 Rausch 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
37th percentile

Out of 430 buildings in this neighborhood, 271 are predicted to be safer.
