Initial analysis

The 12-unit, 3-story multi-family residential building at 40 Parkridge Drive in Twin Peaks, owned by David & Sonia Chan Trust and constructed in 1966, has undergone several significant safety and maintenance improvements over recent years. The building completed mandatory soft-story retrofitting in 2016, with work valued at $140,000, and more recently has addressed multiple safety concerns through various permits in 2024, including a fire alarm system upgrade ($37,900) and kitchen-bathroom remodel legalization in Unit #7 ($13,000). However, there are persistent safety and maintenance issues that warrant attention: a routine inspection in 2022 resulted in multiple active violations relating to smoke detection and roof deck safety that remain unresolved as of October 2023, and a 2024 complaint cited electrical hazards and mold issues that were last closed in October 2024 but may require further investigation.

The building's history shows various maintenance challenges, including water damage repairs in 2015 to Units 1 and 3, and recurrent mold issues in 2016 and 2024. Fire safety has been an ongoing concern, with violations in 2020 regarding storage in mechanical rooms and extinguisher servicing that were subsequently abated, and more recently completed fire alarm system upgrades in 2023. The property has demonstrated responsiveness to tenant concerns, as evidenced by multiple completed permits for unit-specific improvements, though some violations from 2022-2023 remain active. Recent 311 calls in 2024 indicate ongoing issues with debris and possible structural concerns, while building inspection records show a pattern of addressing but not fully resolving certain safety issues, particularly regarding smoke detection and roof deck safety.

Risk rating

How 40 Parkridge Dr'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
59th percentile

Out of 172 buildings in this neighborhood, 71 are predicted to be safer.
