Initial analysis

The two-unit, one-story multi-family residential building at 3621 22nd Street in Noe Valley was built in 1905 and is currently owned by the Hiu Lo & Norbert Hu Family Trust. The building's maintenance history shows attention to structural upkeep, with documented termite repairs completed in December 1995, and two separate instances of reroofing work performed in 1989 and 2006, the latter costing $3,700.

Recent incidents concerning the property have primarily involved exterior maintenance and urban infrastructure issues rather than building-specific problems. Between 2020 and 2024, there have been several street-related incidents including garbage and debris complaints in September 2024, graffiti reported in September 2024, and two illegal parking complaints in 2022. The building's most significant maintenance challenges appear to have occurred in 2020 and 2021, with documented sewer issues including a vent problem in July 2021 and an Environmental Health Department transfer in August 2020. Earlier historical records show streetlight problems in 2013, with one light flickering and another dimmed, both of which were subsequently resolved by PG&E. While there have been periodic maintenance and infrastructure issues in the surrounding area, there are no documented safety concerns directly related to the building itself in the most recent years, and the property's historical records demonstrate regular maintenance addressing both structural and environmental concerns when they arise.

Risk rating

How 3621 22Nd 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
70th percentile

Out of 1879 buildings in this neighborhood, 564 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.

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 80.1%
Moderate concern 15.1%
Severe concern 4.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.

We want to replace the pitched roofing with a box-shaped second floor and are wondering what our guardrails are. Additionally, we are wondering whether we are able to touch the front facade of the structure, including possibly extending it forward towards the street.
