Initial analysis

The two-unit residential building at 850-852 26th Avenue in the Central Richmond neighborhood is a two-story flats and duplex structure built in 1927, currently owned by Vlaho & Yvonne K Vukasin Lv. The property underwent significant improvements between 2019 and 2021, most notably the legalization of an additional dwelling unit on the first floor, which included comprehensive safety upgrades such as a new fire sprinkler system with 22 heads, and a sprinkler monitoring system costing over $16,000 combined. The building's infrastructure received substantial modernization, including the installation of a Navien tankless water heater, replacement of the furnace with a high-efficiency unit, and extensive gas line upgrades.

The property has experienced ongoing parking-related issues, particularly since late 2021, with multiple complaints about driveway blocking resulting in citations being issued to offending vehicles throughout 2022, 2023, and 2024. There was one recorded incident of sidewalk parking (July 2022) and six documented cases of driveway blocking in 2023-2024, with several of these cases resulting in successful citations. While the building's safety infrastructure has been substantially improved, there was one minor incident reported involving a carbon monoxide detector activation in 2021, which did not result in any actual carbon monoxide presence or civilian injuries. The property has maintained compliance with safety regulations, as evidenced by the successful completion of multiple inspections and permit requirements related to the unit legalization and corresponding safety system installations, including electrical system upgrades to meet modern safety standards.

Risk rating

How 850-852 26Th 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
90th percentile

Out of 2250 buildings in this neighborhood, 225 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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Building age

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

Neighborhood location

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

12-Month severity forecast
No violation 82.8%
Moderate concern 13.3%
Severe concern 3.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
