Initial analysis

1811 Castro Street is a two-story, 6-unit multi-family residential building constructed in 1963, currently owned by Family Bypass Trust. The property has undergone several significant safety upgrades in recent years, with the most notable being the complete replacement of the fire alarm system in early 2024 at a cost of $29,584 to comply with San Francisco Fire Code requirements, including new detectors, pull stations, and monitoring equipment. This upgrade was preceded by a fire alarm system malfunction incident in July 2024, though no civilian injuries were reported. The building has had its share of maintenance challenges, with documented issues including mold and mildew on the exterior (2018), peeling paint concerns (2018), and past violations related to fire safety equipment, gas utility shutoff tools, and a fire escape ladder (2022). Historical records show the building received fire safety violations in 2001, which were promptly addressed by July 2001, including corrections to gas meter instructions and smoke enclosure doors.

The property has had periodic routine inspections of common areas, with the most recent being in 2022. An electrical permit was filed in July 2024 for fire alarm system upgrades, demonstrating ongoing compliance with safety regulations. Recent 311 calls for the property mainly involve external issues such as parking violations, tree maintenance needs, and street cleaning matters. A sewage backup incident was reported and resolved in February 2021. The building's solo fire incident record shows minimal impact, with one alarm system malfunction in July 2024 and no reported civilian injuries. The property has maintained regular inspections and address current safety requirements, though historical documentation indicates periods where maintenance and safety compliance required attention.

Risk rating

How 1811 Castro 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

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.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

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 62.8%
Moderate concern 24.6%
Severe concern 12.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
