Initial analysis

The three-unit residential building at 439-441 Tehama Street in the South of Market neighborhood is a three-story flats and duplex structure built in 1906 and currently owned by Erik Robbins. The property has undergone several significant maintenance and upgrade projects over the past decades, with the most substantial recent work occurring in 2020 when the building received comprehensive improvements including a complete roof replacement (cost: $20,000) and a major electrical service upgrade with the installation of new 400-amp underground service connections. Prior to these updates, the building had its basement upgraded with a concrete floor in 1990, plumbing system improved with new water heaters in 2009, and several exterior maintenance works including termite repairs and siding replacement in 1993, along with window replacements in 2000.

The building has maintained relatively good compliance with housing standards, though it experienced one plumbing and electrical violation in 2005 related to a sidewalk cleanout cover, which was promptly resolved within a month. A complaint was lodged in 2017 regarding unpermitted exterior work and scaffolding, but this appears to have been addressed as no active violations remain on record. More recently, there have been multiple 311 calls regarding the immediate vicinity of the building between 2023-2025, primarily related to sidewalk conditions, trash removal, and parking issues, though none of these directly implicate the building's habitability or management. The most recent recorded incident was a false alarm system activation with no fire or injuries reported. The building's maintenance record shows regular upkeep, with significant investments in infrastructure improvements, particularly in 2020, suggesting proactive management of the property's essential systems.

Risk rating

How 439-441 Tehama 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 430 buildings in this neighborhood, 52 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.

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 57.5%
Moderate concern 32.0%
Severe concern 10.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
