Initial analysis

The two-story, six-unit multi-family residential building at 1225 18th Avenue in the Inner Sunset, owned by Peter Tam, was constructed in 1962 and has undergone several significant renovations over the past decade. Most notably, between 2015 and 2016, three units (Units 1, 3, and 6) received substantial upgrades including kitchen and bathroom remodels, window replacements with energy-efficient units, and electrical system improvements including new subpanels and various fixture upgrades. The building has maintained compliance with housing standards, with routine inspections conducted in 2000, 2002, and 2009 showing some violations that were promptly addressed within roughly one month of being cited. These violations primarily concerned safety issues such as smoke enclosure doors, gas meter instructions, and the need for handrails and fire extinguishers, all of which were resolved by 2010.

Recent history of the property shows minimal internal issues since the 2015-2016 renovations, though there have been several parking enforcement incidents in the area, with citations issued for driveway blocking between 2019 and 2023, including three incidents in late 2022 alone. A general cleaning complaint was filed and resolved in 2019, but no specific residential unit issues have been reported through 311 calls since the major renovations were completed. The building's permit history confirms the completion of all authorized work, including plumbing and electrical permits associated with the various unit renovations, suggesting proper oversight and adherence to building codes during the improvement process.

Risk rating

How 1225 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

Out of 1493 buildings in this neighborhood, 1239 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.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Building age

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

12-Month severity forecast
No violation 46.4%
Moderate concern 22.2%
Severe concern 31.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
