Initial analysis

The 18-unit, 3-story multi-family residential building at 250 Parnassus Avenue, owned by Gaehwiler Family LLC, has undergone significant renovations and safety upgrades since its construction in 1964. Most notably, the building completed a mandatory soft-story retrofit in 2014 (costing $130,000) to improve seismic safety, and in 2021-2022 underwent substantial fire safety improvements including a fire alarm system upgrade ($38,214) and complete replacement of outdated electrical panels (notably replacing Federal Pacific panels) across all units with modern equipment. Recent fire safety inspections in 2024 returned "No Merit" findings regarding fire escape and alarm system complaints, though a routine housing inspection from February 2023 remains active.

The building's maintenance history shows ongoing attention to structural and safety improvements, including window replacements for egress compliance (2013), bathroom remodels (2012), and exterior maintenance work following a 2014 complaint about stucco removal. Historical violations from 2003 related to fire safety and egress obstructions were promptly addressed by December 2003. Recent 311 calls from 2024 mainly concern external issues such as parking enforcement and sidewalk cleaning, rather than building-specific problems. The property has demonstrated regular upkeep through various permits for roofing (2005), plumbing, and electrical work, maintaining compliance with San Francisco building codes and requirements.

Risk rating

How 250 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
8th percentile

Out of 526 buildings in this neighborhood, 484 are predicted to be safer.
