Initial analysis

The two-unit residential building at 128-130 Duncan Street in Noe Valley, owned by Cewl Investments LLC, has undergone significant renovations and improvements over the past few years. Built in 1900, this two-story flats and duplex structure has seen extensive modernization in 2021, with major work including a complete garage reconfiguration, bedroom and bathroom additions, window and door replacements, and comprehensive kitchen and bathroom remodels in both units. The $130,000 garage and upper unit remodel in March 2021 involved structural modifications including the removal of load-bearing walls and installation of new beams. Both units received new electrical systems, including a 200-amp service upgrade with three new meters, and new HVAC systems with gas furnaces and AC units installed in August 2021. A notable tenant buyout occurred on August 24, 2021, with compensation of $65,000 for two tenants.

The building's recent maintenance history shows regular upkeep, including a completed reroofing project in August 2021 costing $12,000. The property underwent substantial interior improvements in 2021, including plumbing upgrades with new bathrooms and kitchen fixtures in both units, though some work was cancelled or revised, such as the electrical permit that was marked as cancelled in April 2021. The building experienced some external issues in 2023, including reports of non-offensive graffiti, though these were part of a broader pandemic-related backlog of complaints that affected many properties in San Francisco. The property has a history of occasional parking-related complaints, with several cases of driveway blocking reported between 2019-2022, but these were generally resolved by enforcement agencies. Historical records show earlier permits from 2004 and street space permits from 2005 and 2017, indicating the property's long-standing residential use.

Risk rating

How 128-130 Duncan 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
93th percentile

Out of 1879 buildings in this neighborhood, 132 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.

Neighborhood (ZIP code)

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

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

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 91.0%
Moderate concern 7.0%
Severe concern 2.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
