Initial analysis

735 11th Avenue is a 2-story, 5-unit multi-family residential building located in San Francisco's Inner Richmond neighborhood, constructed in 1923. The property has undergone significant improvements and addressed various maintenance issues over the years, with the most recent major work being a completed seismic retrofit in 2015 that included installation of plywood shearwalls, holdowns, and new foundation work at the garage/street level, which was classified as a Tier 3 soft-story retrofit project that is now CFC (Certificate of Final Completion) issued. The building has seen substantial interior unit improvements, particularly in 2008-2009, including comprehensive renovations of several units with updated kitchens, bathrooms, electrical systems, and heating elements, as well as the installation of a fire sprinkler system. In 2016, vinyl siding was added to the back left wall of the building.

The property's maintenance history reveals several periods of tenant concerns, particularly between 2007-2008, when multiple complaints were filed regarding heating issues, water problems, construction concerns, and interior maintenance. These issues appear to have been addressed through subsequent repairs and improvements. A notable cluster of violations was recorded in 2002, primarily related to fire safety and interior surfaces, including requirements for fire extinguishers, paint maintenance, and self-closing doors, all of which were abated by May 2002. The building has maintained an active record of regular maintenance and upgrades, including plumbing improvements such as heater installations and gas line extensions, electrical system upgrades, and compliance with safety regulations. Recent 311 calls from 2019-2020 primarily relate to external issues such as street pavement and signage, rather than building-specific concerns.

Risk rating

How 735 11Th 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

Out of 1723 buildings in this neighborhood, 1430 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

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 58.0%
Moderate concern 16.7%
Severe concern 25.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
