AI summary

This 2-unit, 2-story multi-family residential building, located at 4826-4828 California Street in the Lake-The Presidio neighborhood, was constructed in 1923 and is currently owned by the Lin/Liu Family Trust. The building underwent significant renovations in 1996, including kitchen and bathroom remodels for both units, front wall stucco repair, and the addition of garage-level rooms for the lower floor owner-occupant, with the completed work totaling approximately $18,000. An expired permit from 1996 for staircase construction suggests incomplete work in that area. The property experienced some compliance issues in 2005 when an unpermitted accessory building approximately 8x16 feet was constructed in the rear yard, though these violations were abated by May 2005 through proper code enforcement channels.

The building has had two documented sewer backup incidents (2009 and 2012) that required PUC Sewer Operations intervention, though these issues were resolved. More recent maintenance and service calls include various municipal services such as street lighting (2017), tree maintenance (2016), and sign repair (2019). The most recent service calls in 2024 involve a garbage and debris report and a parking enforcement request, both of which were either closed without resolution or unable to be fully addressed by responding officers. While the building has had some maintenance issues in the past, particularly regarding sewer systems, these have been addressed through appropriate channels, and there have been no documented safety violations or building code issues in recent years. The property has maintained its original duplex configuration throughout its history, with all significant modifications occurring in the mid-1990s.

Risk rating

How 4826-4828 California 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
62th percentile

Out of 660 buildings in this neighborhood, 251 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.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

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 79.4%
Moderate concern 16.4%
Severe concern 4.1%
