Initial analysis

The 5-unit, 2-story multi-family residential building at 106 18th Avenue, owned by Stammi Investments LLC, has undergone significant safety improvements since its construction in 1915. Most notably, the building completed mandatory soft-story retrofitting in 2014 at a cost of $50,000, achieving compliance with San Francisco Building Code requirements. Recent fire safety upgrades include a $27,350 fire alarm system enhancement completed in 2023 to meet current fire code requirements, including the installation of low-frequency sounders in sleeping areas and updating all devices to be compatible with the new fire alarm control panel. The property has also addressed essential infrastructure maintenance, including sewer line replacement and house trap work in 2014, and a Ufer ground installation in 2014 to improve electrical safety.

The building's maintenance history shows proactive responses to both routine inspections and specific issues, such as a broken sewage pipe incident in 2014 and various routine inspections dating back to 1996. While there were several building violations documented in 2002 related to fire safety, lead paint hazards, and security issues, these were all abated by October 2002. Recent fire alarm complaints in late 2024 were found to have "No Merit," and the building's fire incident history primarily consists of false alarms and system malfunctions, with no recorded civilian injuries. The property is currently classified as a Tier 3 Soft Story building with completed work and a Certificate of Final Completion issued. Recent 311 calls have primarily concerned external issues like tree damage, abandoned vehicles, and street cleaning matters rather than building-specific concerns.

Risk rating

How 106 18Th 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
23th percentile

Out of 660 buildings in this neighborhood, 508 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.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

12-Month severity forecast
No violation 73.5%
Moderate concern 18.4%
Severe concern 8.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
