Initial analysis

The 11-unit apartment building at 4717-4721 Mission Street in the Excelsior neighborhood, owned by Leung Sze Yuen & Tracy Ho, has undergone several significant structural improvements since its construction in 1926. Most notably, the property completed mandatory soft-story retrofits in 2024, including both residential and commercial improvements with steel framing and shearwalls, though initial permits filed in 2018 for these works had expired. More recent permit activity in 2024 includes revisions to remove ADA components from previously approved work. The building has a history of commercial space challenges, with multiple complaints about vacant storefronts in 2023, following a 2019 attempt to convert retail space into office/display/storage uses, which was eventually withdrawn.

The property has undergone routine housing inspections between 2000-2011, with an active complaint from 2023 regarding vacant commercial spaces. Building violations from 2000 related to various safety issues, including combustible storage, electrical problems, and fire safety concerns, were all abated by July 2000. Recent 311 reports (2023-2024) primarily relate to external maintenance issues such as graffiti, general street cleaning, and debris removal, though most of these have been resolved. While the building appears to be compliant with current soft-story requirements and recent permit revisions, the ongoing commercial vacancy situation may impact the property's overall viability. The most recent routine inspections and soft-story completion status suggest improved structural safety, though the withdrawal of the 2019 change of use application indicates challenges in repurposing the commercial space.

Risk rating

How 4717-4721 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
1th percentile

Out of 337 buildings in this neighborhood, 334 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.

Building size

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

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 12.2%
Moderate concern 56.7%
Severe concern 31.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
