Initial analysis

This two-unit residential building, located at 481-483 Mississippi Street in Potrero Hill, is a two-story flats & duplex structure built in 1900, currently owned by Christian J Randecker and Yip. The property has undergone significant improvements and maintenance work over the past two decades, with particular attention to bathroom and window upgrades. Most recently, in 2013, electrical improvements were completed in the living room and bedroom, including the installation of recessed lighting and fire safety features. The building has seen substantial bathroom renovations, with major work performed in 2008 (Unit 481) and 2009 (including a new laundry room), and multiple window replacements in 2010 and 2013. Structural maintenance has been addressed through various permits, including dry rot repairs in 2010 and multiple plumbing and electrical updates.

The property has experienced several infrastructure and maintenance issues over the years, with the most concerning being a sewage backup incident in 2016 that required municipal intervention. More recent external issues have included multiple reports of sidewalk defects between 2018 and 2023, primarily related to tree root damage, though these have generally been resolved. The building's systems have been regularly updated, with particular attention paid to electrical systems, as evidenced by multiple permits for panel and wiring work between 2005 and 2013. While there have been various service requests and complaints filed through 311, most relate to external issues such as illegal postings, sidewalk conditions, and parking enforcement, rather than building-specific problems. The property's maintenance record shows consistent attention to both routine improvements and reactive repairs, with no single area of persistent concern.

Risk rating

How 481-483 Mississippi 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
64th percentile

Out of 726 buildings in this neighborhood, 261 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.

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.

Property class: multi-family flat

2–4 unit flats (class F) are a common SF building type with their own maintenance and complaint patterns.

12-Month severity forecast
No violation 77.6%
Moderate concern 17.3%
Severe concern 5.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
