Initial analysis

243 Parnassus Avenue is a 3-story multi-family residential building constructed in 1908, containing 6 units and currently owned by Li Jieyi & Mu Ying. The property has undergone several significant improvements over the past two decades, with the most recent major work being completed in 2010, including bathroom renovations in Unit #4 (tub replacement and fixture updates) and some electrical work, though certain electrical permits from that period were marked as cancelled. Earlier improvements include a substantial heating system upgrade in 2006-2007, where wall heaters were replaced in multiple units and new furnaces were installed in Units 1 & 2. A notable structural improvement was attempted in 2006 with the installation of anchor bolts to secure the building's foundation, though this permit shows as expired.

The building experienced several violations in December 2009 related to fire safety requirements, specifically regarding fire proofing materials and gas utility shutoff tools, all of which were resolved by January 2010. There was also a complaint about unauthorized demolition work in March 2013, which was marked as not active. Historical complaints from 1997 indicated some maintenance issues with the main door and back stairs, though these were resolved promptly. Recent activity around the property has primarily involved external maintenance concerns, with multiple reports in 2024 about garbage, debris, and toter management on the premises. The most recent documented incident related to the building was a carbon monoxide detector activation (with no actual CO detected), though no civilian injuries were reported.

Risk rating

How 243 Parnassus Ave'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 526 buildings in this neighborhood, 405 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.

Estimated permit spend (past 7 years)

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

Building size

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

12-Month severity forecast
No violation 56.6%
Moderate concern 20.6%
Severe concern 22.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
