Initial analysis

The property at 631-633 34th Avenue is a two-unit, two-story multi-family residential building located in the Outer Richmond neighborhood, built in 1925. The building has undergone several significant renovations and proposed modifications over the past decade, including multiple attempts to add an ADU (Accessory Dwelling Unit) on the first floor, with the most recent permit filed in February 2020 currently in filed status. Major renovation work was completed between 2015-2017, including interior remodeling of the second floor (2017), ground floor modifications to add a meeting room, media room, half-bath, exercise room, and laundry facilities (2015-2016), along with associated electrical, plumbing, and HVAC upgrades. Earlier construction work in 2015-2016 prompted several tenant complaints regarding dust, debris, and safety concerns, and there were also issues reported in 2010 related to unsafe paint removal practices.

More recent concerns have emerged, particularly a complaint filed in July 2022 regarding the allegedly illegal nature of an in-law unit, along with reports of plumbing and fire safety issues, though this complaint is currently listed as not active. The building has a history of parking-related complaints, with multiple citations issued between 2020-2022 for vehicles blocking driveways, and a hazardous materials complaint was resolved in early 2021. The property's permit history shows a pattern of attempting to create additional living space through various modifications, some of which have been completed while others remain in various stages of approval or cancellation. The building's infrastructure has received considerable attention, with multiple furnace installations/replacements, electrical rewiring, and plumbing upgrades completed between 2015-2017. A historical foundation and retaining wall replacement was completed in 1990, and sidewalk repairs were addressed in 2002.

Risk rating

How 631-633 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.
