Initial analysis

The 12-unit, three-story multi-family residential building at 3300 Laguna Street in the Marina district, owned by the Kay Yu Trust, was constructed in 1924 and has undergone significant improvements over the past decade. Most recently, in August 2023, work was completed on a new laundry room installation in the garage, including the installation of washing machines and dryers. The building successfully completed its mandatory soft-story retrofit in 2016, which involved adding shear walls, new foundation work, and required structural improvements, demonstrating compliance with seismic safety requirements. Several units have received substantial renovations, including Unit 12 (2015 remodel with new bathroom), Unit 3 (2014 kitchen renovation), and Unit 6 (2014 conversion of coat closet to laundry room).

The building has experienced some maintenance challenges, with a burst hot water pipe incident in 2016 causing water damage across multiple units, and recent concerns regarding window safety in July 2024. Historical violations from 2001 included various issues such as plumbing, electrical, and fire safety concerns, though all were addressed and abated by 2002. The property's fire safety systems have been regularly maintained, with corrections made to alarm systems in 2022 and fire extinguishers in 2017. The building has undergone multiple routine inspections and renovation projects over the years, with the most recent being the laundry room installation completed in 2023, indicating ongoing investment in property maintenance and improvements. Recent 311 calls from 2024 primarily relate to street cleaning and debris removal, rather than building-specific issues, suggesting improved building maintenance in recent years.

Risk rating

How 3300 Laguna 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
26th percentile

Out of 988 buildings in this neighborhood, 731 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.

Building size

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

Estimated permit spend (past 7 years)

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

12-Month severity forecast
No violation 30.0%
Moderate concern 39.6%
Severe concern 30.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
