Initial analysis

The two-unit residential building at 723 34th Avenue in San Francisco's Outer Richmond neighborhood, owned by Mark Bloom and Cynthia Vaughn, is a two-story flats/duplex structure built in 1955. The property has seen several significant improvements in recent years, most notably a substantial renovation in 2022 involving bathroom remodels in unit #725 ($30,000) followed by kitchen upgrades ($13,000), with corresponding plumbing and electrical work completed in July 2022. In 2021, a noteworthy electrical upgrade was performed, including the installation of 18 photovoltaic solar panels and a service upgrade. The building's history shows a fire incident in 1996 that required repairs, and a 1996 permit (now expired) aimed at legalizing a social room, restroom, and fire-rated wall on the garage.

Recent maintenance issues have primarily involved exterior concerns, with multiple 311 calls in 2024 regarding waste management (toters left out), and several parking enforcement calls between 2022-2024 for vehicles blocking driveways or parking on sidewalks. A sewer vent odor issue was reported and resolved in April 2023, and there was an incident of street flooding reported in September 2021. While these maintenance issues have been addressed by city services, none represent immediate concerns about the building's structural integrity or resident safety. The property's recent improvements, including the solar panel installation and comprehensive unit renovations, suggest ongoing active management and maintenance by the current owners.

Risk rating

How 723 34Th 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
91th percentile

Out of 1040 buildings in this neighborhood, 94 are predicted to be safer.
