Initial analysis

The 400 Laguna Street property, developed by Hayes Valley LP, is a mixed-use building constructed through 2013-2014, featuring approximately 182 residential units, ground-floor retail space, and a fitness center. Recent significant concerns include an active violation from August 2023 regarding damaged glass panes (25+ damaged and 1 broken) on the building's east facade, likely caused by heat from a nearby fire. The building has undergone several important safety and security upgrades in recent years, including a sound level verification in sleeping areas (2024), the installation of additional fire alarm strobes (2022), and substantial fire sprinkler system revisions (2022).

The property has faced various maintenance and service issues over the years, particularly concerning water systems, with complaints about low water pressure and recurring hot water outages in 2016 and 2022, respectively. Security improvements have been a focus, with multiple permits filed in 2022 to increase fence heights and enhance overall building security. The building's infrastructure has seen significant investment, including the installation of a comprehensive fire alarm system (2014), solar water collectors (2014), and various electrical upgrades including EV chargers (2019) and common area lighting improvements (2019). Recent service calls in 2024-2025 have primarily involved street cleaning issues outside the building, including reports of human waste and needles near the property boundaries.

Risk rating

How 400 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.
