Initial analysis

The two-unit residential building at 647-649 14th Avenue in the Central Richmond neighborhood, constructed in 1922 and currently owned by the Erin Thompson Trust, has undergone significant renovations and faced several maintenance challenges over the past decade. The property experienced substantial improvements in 2015, including comprehensive kitchen and bathroom remodels, the addition of a half bathroom, laundry relocation, and electrical upgrades, with permits totaling over $80,000. More recently, the building has encountered issues with fire safety compliance, receiving multiple violations between 2019 and 2024 related to documentation, alarm system maintenance, and fire extinguisher upkeep, though records indicate these have been abated. The building's mechanical systems have seen regular updates, including furnace replacements in 2015 and a water heater replacement in 2014, along with window replacements completed in 2010.

Of particular note, the property has experienced recurring fire alarm system issues, with four documented false alarms between 2019 and 2024, and multiple fire code violations issued in recent years. The most recent building-related complaint was filed in April 2023 regarding noisy turbine exhaust vents on the roof, though this was promptly addressed. Historical issues include a drainage problem between properties documented in 2004-2012, and three complaints about unauthorized business use between 2007-2009. The building's recent history shows regular maintenance updates and prompt responses to violations, though the pattern of fire safety violations suggests ongoing attention is needed in this area.

Risk rating

How 647-649 14Th 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.
