Initial analysis

The three-unit, three-story multi-family residential building at 519-523 Dolores Street, owned by the Howarth Slaker Family Trust, was built in 1904 and has undergone substantial renovations and improvements over the past two decades. The most significant recent work occurred in 2013, when major updates were completed in units 521 and 523 including new kitchens, washer/dryer installations, bathroom renovations, electrical updates, and the addition of forced air heating, totaling approximately $120,000. The garage area received particular attention in 2013 and 2010, with structural improvements, seismic upgrades, and the widening of the garage entry, along with new planters and driveway modifications costing $45,000. The building's systems have been regularly maintained, with recent electrical work in 2022 involving the installation of new outlets, and plumbing upgrades including water heating system improvements in 2011 and comprehensive bathroom and kitchen plumbing work in 2013.

The property has had several maintenance and safety issues documented through building violations and complaints, primarily between 2002 and 2009.

Risk rating

How 519-523 Dolores 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.

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 (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Building size

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

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 55.0%
Moderate concern 20.0%
Severe concern 25.0%
