Initial analysis

The 5-unit, 5-story apartment building at 833 Corbett Avenue in Twin Peaks, owned by R.E.A.L. Properties, has a documented history of addressing key safety concerns, particularly regarding seismic retrofitting and fire safety systems. The building completed its mandatory soft-story retrofit in 2019 at a cost of $124,000, following earlier violations for non-compliance in 2017 that led to monitoring fees. Fire safety has been a recurring focus, with violations related to alarm systems in 2019 and 2021 (both abated), and a combustible materials violation in 2015 that was corrected. The building experienced significant fire damage in unit 5 in 2000, which was repaired at a cost of $75,000, and underwent various maintenance including reroofing projects in 2009 and 2017 totaling over $35,000.

Recent maintenance issues have primarily involved sewage systems, with multiple reports of sewer discharge incidents from late 2024 to early 2025, indicating possible ongoing infrastructure challenges. The building's history includes several interior maintenance issues from 2002-2003, particularly relating to water damage and mold problems, though these have been addressed. A routine inspection failure notice was issued in 2009, but subsequent inspections appear to have resumed. The property has maintained compliance with San Francisco's soft-story retrofit program, as evidenced by the completion certification, though its Tier 3 designation indicates it required additional work. Recent 311 calls have primarily concerned parking issues and one building inspection request in 2024, suggesting relatively few recent problems beyond the sewage system concerns.

Risk rating

How 833 Corbett 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
78th percentile

Out of 172 buildings in this neighborhood, 38 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building size

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

12-Month severity forecast
No violation 45.1%
Moderate concern 22.6%
Severe concern 32.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
