Initial analysis

The two-story, 4-unit multi-family residential building at 835-837 Union Street in Russian Hill, owned by Mwamba Everest, was constructed in 1909 and has undergone several significant improvements in recent years. Most notably, in 2022, there was a permitted window replacement project for six non-street facing windows, and a substantial interior remodel of one unit that included kitchen and bathroom renovations along with a living room modification, totaling approximately $65,000 in improvements. The building received comprehensive electrical upgrades between 2018-2019, including the installation of new 100-amp electrical panels and extensive rewiring for kitchens and bathrooms in multiple units. Prior improvements included a complete reroofing project in 2018, installation of central forced air heating units in 2019, and various plumbing renovations for kitchen and bathroom remodels throughout the building.

The building's maintenance record shows attention to both structural and safety systems, with multiple completed permits for essential systems including plumbing and electrical work. A routine housing inspection conducted in 2005 resulted in several fire safety-related violations, including issues with fire extinguishers, gas meter instructions, and smoke detectors, though all were officially abated by January 2006. The property has experienced minimal recent issues, with only three 311 calls in the past six years, primarily regarding waste container management and one sewage backup incident in 2017, all of which have been resolved. There are currently no active violations or complaints against the property, and no tenant buyouts have been recorded for this address.

Risk rating

How 835-837 Union 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

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 65.2%
Moderate concern 13.6%
Severe concern 21.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
