Initial analysis

The property at 233-235 Corbett Avenue is a three-story, two-unit multi-family residential building located in Corona Heights, built in 1900 and currently owned by Lim Weiming V & Bennet Stew. The building has undergone several significant renovations and maintenance work in recent years, with major roof improvements completed in 2019 including the installation of new roof-mounted HVAC equipment, skylight modifications, and structural reinforcement. That same year, substantial repairs were performed to address dry rot issues in the rear roof and exterior walls, costing $40,000. The upper unit has received comprehensive upgrades including kitchen and bathroom remodels, additional bathroom installation, and various plumbing and electrical improvements between 2018-2019.

The building's history shows some concerns regarding permit compliance and structural modifications. In 2015, there was a violation related to unauthorized basement excavation work and unsafe shoring of building foundations, though this was abated in 2016. A tenant buyout occurred at 235 Corbett Avenue in December 2015 for approximately $41,980. More recent improvements include multiple street space permits in 2019-2020, and a roofing project completed in September 2019 costing $5,000. The building has experienced routine maintenance issues addressed through 311 calls, including a flooding incident in 2019 that required attention from PUC Sewer Operations. While there have been some complaints about work done without permits in the past, most notably in 2019 regarding front work, and concerning windows in 2014, these complaints have been marked as not active. The property's permit history demonstrates regular updates to both units, with particular attention paid to plumbing, electrical, and structural systems over the past decade.

Risk rating

How 233-235 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
99th percentile

Out of 348 buildings in this neighborhood, 3 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.

Building permits (past 7 years)

Number of permits pulled at this address — construction or renovation activity over 7 years.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

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 90.3%
Moderate concern 8.1%
Severe concern 1.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
