Initial analysis

The 5-unit, 3-story apartment building at 436-438 Tehama Street in the South of Market neighborhood, owned by A&M One LLC, has undergone significant renovations and faced multiple maintenance challenges since 2018. Built in 1907, this multi-family residential building has completed various improvement projects, including a major $70,000 kitchen and bathroom renovation in 2022 across multiple units (436A, 438B, 438C), followed by office conversion projects in units 436A, 436C, and 438C between 2018-2022. The property has a completed soft-story retrofit (Tier 4) to address seismic concerns.

Recent and ongoing issues are concerning, particularly in the past year. Current active complaints (2024) highlight significant maintenance problems, including inoperative plumbing, electrical systems, and heat; security concerns with compromised door locks; and pest control issues. Historical violations from 2017 (now abated) included multiple fire safety and security concerns such as problematic egress, combustible storage issues, and rodent infestation. The building underwent a substantial unit reconfiguration process between 2021-2022, attempting to convert the top floor back to two units and make various improvements, including a $2,500 bathroom fan installation in 2024 to comply with a notice of violation. Recent complaints indicate persistent maintenance issues, with tenants reporting problems dating back to their occupancy in 2023. The property has also experienced various environmental concerns, including a 2024 complaint about bathroom ventilation creating potential mold hazards.

Risk rating

How 436-438 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.
