Initial analysis

The 12-unit apartment building at 400 Locust Street in Presidio Heights, owned by Sambado A T Apartment Trust, has undergone several significant safety and infrastructure improvements since its construction in 1907. Most recently, in late 2023, the building received a fire alarm system upgrade to comply with San Francisco Fire Code requirements, including the installation of low-frequency sounders in sleeping areas and updating all existing devices. The property completed its required soft-story seismic retrofitting in 2017, installing moment frames and shearwalls to comply with San Francisco Building Code requirements.

The building has experienced some safety-related issues in recent years, particularly in 2019 when multiple citations were issued regarding smoke detectors, carbon monoxide alarms, and fire safety systems, though many of these violations were abated by December 2019. While there were fire safety complaints in 2021 and 2022 regarding combustible materials and sprinkler systems, these were either corrected or found to have no merit. The building's electrical systems have received attention as well, with a 2021 project replacing fuse sub-panels with breaker sub-panels in 10 apartments. Recent maintenance issues have primarily involved building systems and safety elements, including a current active violation concerning a garbage chute repair. The property has experienced periodic maintenance and cleanliness issues on the exterior, as evidenced by multiple 311 calls throughout 2024 regarding garbage, debris, and sidewalk maintenance, though these appear to be promptly addressed by city services.

Risk rating

How 400 Locust 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

Out of 181 buildings in this neighborhood, 163 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

12-Month severity forecast
No violation 42.1%
Moderate concern 40.3%
Severe concern 17.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
