Initial analysis

The four-unit, two-story multi-family residential building at 475-477 4th Avenue in the Inner Richmond district, owned by Emmanuel & Julie Pun since 2005, has undergone significant modernization and renovations since 2018. The most substantial project, completed in 2018, involved a $200,000 renovation of the front building, including foundation replacement, interior wall updates, kitchen and bathroom remodeling in both units, window replacements, and repairs to dry-rotted wood siding. That same year, the property underwent major infrastructure upgrades, including electrical system improvements with new panels and wiring, plumbing work including kitchen and bathroom remodeling, installation of on-demand water heaters, and replacement of underground sewer pipes. The rear building saw the legalization of a first-floor dwelling unit in 2018-2019, with comprehensive updates to its systems including new electrical, plumbing, and HVAC installations.

The building's maintenance record shows attention to structural integrity and resident comfort, with earlier renovations in 2009 addressing foundation issues, room layout changes, and bathroom and kitchen remodels. The property has experienced some infrastructure challenges, with two documented sewage backup incidents in 2019-2020, though the issues were addressed by PUC Sewer Operations. Recent exterior maintenance included street space permits in 2018. The building's location has experienced recurring issues with sidewalk parking violations, with multiple enforcement actions taken between 2019-2022, though these are exterior matters unrelated to building conditions. A minor cooking-related fire incident occurred at some point, but with no civilian injuries reported. The property's comprehensive renovations and modernization efforts suggest a focus on maintaining and improving the building's infrastructure and resident amenities, though prospective tenants should be aware of the building's age (constructed in 1906) and the relatively recent history of sewer-related issues.

Risk rating

How 475-477 4Th Ave'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 1723 buildings in this neighborhood, 1120 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.

Estimated permit spend (past 7 years)

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

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 69.8%
Moderate concern 18.6%
Severe concern 11.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
