Initial analysis

The three-unit, three-story multi-family residential building at 406-410 Haight Street, owned by Karl Benedikt Buenz, was constructed in 1900 and has undergone several significant maintenance and improvement projects in recent years. Most recently, in late 2023, the building received comprehensive window upgrades, with 24 Marvin Infinity windows installed in the back and lightwell areas, costing $30,000. In October 2023, emergency bathroom repairs were conducted to address water damage, involving replacement of fixtures, cabinets, tiling, and painting at a cost of $28,500, along with associated plumbing and electrical work. The building's infrastructure improvements continued in 2022 with a completed reroofing project costing $28,800, and as of November 2024, all three units (406, 408, and 410) received new furnace installations.

Historical maintenance records show significant past improvements, including a complete window replacement project in 2010 for the front-facing windows, installation of fire sprinklers in 1999, and replacement of a broken house trap in 2017. The building has experienced periodic issues that have required attention, including three housing complaints in the 1990s-2000s concerning various maintenance matters, though all were resolved. More recent concerns primarily involve parking enforcement matters, with multiple reports of driveway blocking in 2024, which were generally addressed by parking enforcement officers. The property has maintained an active response to maintenance needs, as evidenced by the recent furnace replacement project in late 2024 and prompt attention to water damage repairs in 2023. The building's maintenance history shows regular upgrades to essential systems and prompt response to emergency repairs, suggesting generally responsible property management practices.

Risk rating

How 406-410 Haight 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
95th percentile

Out of 1027 buildings in this neighborhood, 51 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.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

12-Month severity forecast
No violation 78.6%
Moderate concern 13.8%
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.
