Initial analysis

The property at 4843-4845 Mission Street is a three-story, mixed-use building constructed in 1922, containing five residential units plus commercial space, currently owned by Chester Foon and Valerie Yee. The building has undergone several significant improvements over the past few years, including plumbing work in 2022 to replace the street trap and sewer, and kitchen appliance upgrades in 2021. The commercial portion of the building has maintained active use, with recent planning approvals for a limited restaurant and bakery operation within the Excelsior Outer Mission NCD Zoning District.

The property has experienced recurring maintenance challenges, particularly with graffiti, with multiple incidents reported between 2020 and 2023. These incidents coincided with the period when the San Francisco Board of Supervisors suspended enforcement of the Graffiti Ordinance during the COVID-19 pandemic, leading to a backlog of unresolved cases. Other maintenance issues have been documented through 311 calls, including a sidewalk defect reported in 2020 (still open as of mid-2023) and problems with an abandoned parklet in 2022. The building's plumbing infrastructure has received attention throughout its history, with records showing work on sewer systems, including a grease trap installation in 2012. While the property shows evidence of regular maintenance and responsiveness to basic infrastructure needs, the recurring graffiti issues and some unresolved sidewalk conditions suggest ongoing external maintenance challenges.

Risk rating

How 4843-4845 Mission 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

Out of 337 buildings in this neighborhood, 256 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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 55.5%
Moderate concern 14.2%
Severe concern 30.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
