Initial analysis

The three-story multi-family residential building at 629 33rd Avenue in the Outer Richmond, owned by the Mary King Trust, was constructed in 1928 and contains 6 units. The property has undergone several significant structural improvements, including mandatory soft-story retrofit work completed in 2017 at a cost of $85,000, which involved installing new moment frames and shearwalls to meet San Francisco building codes. Recent maintenance includes a 2023 siding replacement (approximately 300 sqft) following wind damage, and a 2022 reroofing project, demonstrating ongoing investment in building upkeep.

The building has experienced various maintenance and code compliance issues over its history, with the most significant cluster of violations occurring in 2001, including security violations, fire safety concerns, and plumbing/electrical issues, all of which were abated by October 2001. A notable complaint from 2019 regarding falling wall sidings was recorded, though this appears to have been addressed through subsequent repairs. The property has required multiple fire alarm system corrections (most recently in December 2021) and had one instance of blocked exits in 2007, all of which were promptly resolved. Historical complaints from the 2000s indicate periods of various maintenance challenges, including mold issues, plumbing problems, and pest concerns, though these appear to have been addressed at the time. Recent 311 calls primarily relate to external sidewalk conditions and street cleanliness issues, rather than building-specific problems, suggesting improved interior maintenance in recent years.

Risk rating

How 629 33Rd 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 1040 buildings in this neighborhood, 874 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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

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 71.4%
Moderate concern 18.3%
Severe concern 10.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
