Initial analysis

The two-story multi-family residential building at 1439-1441 Baker Street in Lower Pacific Heights, constructed in 1900, consists of three units and has undergone several significant modifications since the 1980s. The property has seen major structural work in 1989, including the replacement of dry rot-staffected elements, foundation extension, and stair repairs, with additional improvements like fire rating upgrades and partition wall construction. In 1990, there was a notable reduction in building height by 5 feet to comply with a violation, and in 2014, the building received a new roof through an $8,000 permit. More recently, there have been multiple parking-related issues around the property, with three documented citations for driveway blocking in 2023-2024, and a significant number of street cleaning requests for debris and abandoned items. Of particular note, from 2013-2014, there was a confirmed violation regarding unauthorized short-term rentals through Airbnb, which was subsequently addressed and abated. The building experienced three fire-related incidents, though none resulted in civilian injuries or confirmed fires. Recent complaints include an open public health service request from December 2024. Historical records show various completed improvements and modifications, including the installation of aluminum siding in 1984 and the conversion of a social room to a bedroom in 1990. The most recent significant complaint involved improper bathroom modifications in 2007, which was resolved by March 2008.

Risk rating

How 1439-1441 Baker 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
54th percentile

Out of 670 buildings in this neighborhood, 308 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.

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.

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 69.9%
Moderate concern 20.9%
Severe concern 9.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
