Initial analysis

The property at 2174-2178 Sutter St is a three-story, four-unit multi-family residential building located in Lower Pacific Heights, constructed in 1900 and currently owned by Thian-ngern Thammasak & Thi. The building has undergone several significant improvements, most notably in 2010-2013 when major vertical and horizontal additions were completed, including the installation of new full bathrooms, laundry rooms, kitchen facilities, and two new water heaters, followed by comprehensive electrical upgrades with a 400-amp service installation. Recent maintenance includes a December 2023 repair of the building's front due to damage from a car accident, while the property has also experienced notable plumbing work in 2013 with the installation of new sewer lines and water systems, and heating system upgrades for units 2178A and B.

The building's maintenance history shows attention to infrastructure with multiple plumbing and electrical upgrades, including bathroom remodels, deck repairs, and window replacements. However, there have been some resident-impacting issues, including a sewage backup incident in March 2021 and a broken house trap complaint reported in April 2021. The property has required various exterior maintenance and repair work over the years, including fire-related repairs in 2007, and the replacement of rear siding and windows in 2009. Recent 311 calls have mostly concerned exterior and neighborhood maintenance issues such as tree root problems (opened in November 2023), street cleaning, and a driveway blocking incident in 2024, though these are primarily neighborhood-level concerns rather than building-specific issues. The building's permit and inspection history indicates regular maintenance and upgrading of essential systems, with no recent history of major structural or safety violations.

Risk rating

How 2174-2178 Sutter 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

Out of 670 buildings in this neighborhood, 482 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.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

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 60.8%
Moderate concern 25.9%
Severe concern 13.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
