Initial analysis

The three-unit multi-family residential building at 26-28 Cumberland Street, located in Mission Dolores, is a three-story flats and duplex structure built in 1907 and currently owned by the Mary R O'Connell Survivors Trust. The property has undergone significant and consistent improvements over the past decade, with particularly substantial renovations in recent years. Most notably, in 2023 and 2022, unit renovations included comprehensive kitchen and bathroom remodels with new fixtures, appliances, and finishes, while infrastructure upgrades included a furnace replacement with a 95% AFUE model in 2022, flue pipe installations, and electrical system improvements such as new sub-panels and wiring for modern amenities. Of particular concern is a significant foundation repair project completed in 2013 that addressed dry rot damage, though no subsequent structural issues have been reported. The building has maintained an active renovation schedule, including window replacements (both facade and unit-specific), roofing work, and plumbing system updates.

The property had a history of housing code violations documented in 2001 that included issues with garbage receptacles, fire safety equipment, stairs, and floor coverings, as well as concerns about lead paint hazards, all of which were resolved by 2003. A routine apartment inspection was conducted in 2007 with no continuing violations noted. Recent maintenance and service records show regular upkeep of building systems, though there have been multiple 311 calls in the vicinity related to street and sidewalk conditions, including reports of waste and abandoned vehicles, which are external to the building's maintenance concerns. The most recent tenant buyout occurred in October 2022 at unit 28, though the records indicate a buyout amount of $0.00 and one tenant involved. A single fire incident was recorded for the property, though it was determined to be a malfunctioning smoke detector with no injuries reported.

Risk rating

How 26-28 Cumberland 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 799 buildings in this neighborhood, 128 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 76.3%
Moderate concern 16.0%
Severe concern 7.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
