Initial analysis

The property at 831-833 14th Street in Duboce Triangle is a two-unit, two-story multi-family residential building constructed in 1901, currently owned by the Delao Wang Family Trust. The building has undergone several significant renovations and improvements over the years, with the most recent major work being the installation of seven vinyl windows in unit #831 in 2021. A substantial renovation took place in 2009-2010, including kitchen and bathroom remodels with new fixtures, electrical work, and plumbing updates, though some work required remediation of ABS piping that led to multiple notices of violation being issued and subsequently resolved by October 2009. The building's electrical system received significant upgrades in 2009, including the installation of a new 100-amp service load center and various circuits for appliances and lighting.

The property has been subject to routine housing inspections over the years, with records showing inspections in 1999, 2005, and 2010. Several street space permits were issued between 2015-2016, and there have been some maintenance issues noted in recent years, including damaged trees in 2020 and 2021. The building's exterior area has experienced typical urban maintenance challenges as evidenced by multiple 311 calls for street cleaning and waste removal between 2014 and 2021. While the property has experienced some violations and required multiple permits for various improvements, most issues have been promptly addressed and resolved. The most recent building improvements and maintenance history suggest regular upkeep and modernization efforts by the current ownership.

Risk rating

How 831-833 14Th St'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

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.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Neighborhood location

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

Building age

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

12-Month severity forecast
No violation 69.4%
Moderate concern 17.0%
Severe concern 13.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
