Initial analysis

The four-story, 10-unit apartment building at 1230 Washington Street in Nob Hill, managed by Gaehwiler Family LLC, has undergone several significant structural and safety improvements since its construction in 1907. Most notably, the building completed a mandatory soft-story retrofit in 2017 under San Francisco's seismic safety requirements (Tier 3), costing $10,000, with the work receiving its Certificate of Final Completion. The building has demonstrated ongoing commitment to safety infrastructure, with comprehensive electrical panel upgrades completed in 2021 across multiple units (1A, B1, B2, C1-C4, D1, D2), and past structural reinforcement work including foundation repair and crawl space strengthening in 2010 (costing $40,000).

Recent maintenance and safety records indicate regular attention to building systems and emergency preparedness. Fire safety inspections between 2021-2024 have identified and resolved various issues including sprinkler systems, standpipe systems, and extinguishers, with most cases marked as "Condition Corrected." The building's maintenance history includes three sewage-related incidents reported between 2019-2025 (most recently in March 2024), though all were promptly addressed. While the building faced multiple violations in 2000 related to gas meter safety and stair repairs, these were resolved within two months. The most recent tenant buyout in the vicinity was recorded at 1242 Washington Street in January 2020, involving two tenants for $14,000. Current infrastructure concerns include an open sidewalk defect reported in January 2025, though this is external to the building itself.

Risk rating

How 1230 Washington 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
23th percentile

Out of 1125 buildings in this neighborhood, 866 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.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

DBI complaints, owner's portfolio

Complaints across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 18.4%
Moderate concern 39.3%
Severe concern 42.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
