Initial analysis

The three-story, four-unit multi-family residential building at 1415-1417 Guerrero Street in the Inner Mission was constructed in 1900 and is currently owned by the John E Wai 1981 Living Trust. The building has a documented history of maintenance and structural issues, particularly regarding water damage and safety concerns. Between 1997 and 2008, there were multiple complaints and repairs related to roof leaks, water damage, and ceiling issues, including a significant violation case from 2001 that involved multiple safety and maintenance violations such as damaged ceilings, smoke detector problems, and interior surface issues, though these were ultimately abated by 2007. More recent concerns include a 2018 incident where a back door was reportedly nailed shut during adjacent construction work, impacting garbage collection and emergency egress, and a 2025 complaint about overflowing trash bins creating health concerns. The building underwent several repair projects over the years, including roof work in 2005-2008 (with costs ranging from $2,000 to $8,500), staircase repairs, and structural improvements including the installation of new footings and walls with fire-rated assemblies in 2004.

The property has experienced recurring issues with waste management and building maintenance, as evidenced by numerous 311 calls in 2024 regarding garbage, debris, and street cleaning matters. There is also a history of building modifications and improvements, including a proposed project to raise the house approximately three feet and construct a new four-car parking garage with interior and exterior alterations. While many past violations and complaints have been resolved, the recent pattern of waste management issues and the 2018 safety concern regarding the back door suggest ongoing challenges with building maintenance and resident experience.

Risk rating

How 1415-1417 Guerrero 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
41th percentile

Out of 2380 buildings in this neighborhood, 1404 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 size

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

DBI complaint rate, owner's portfolio

Per-building complaint rate across the owner's portfolio.

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 32.9%
Moderate concern 55.4%
Severe concern 11.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
