Initial analysis

The two-story, 8-unit multi-family residential building at 9 Castle Manor Ave, built in 1927 and currently owned by Scholten Family Living Trust, has undergone several significant safety improvements and faced various compliance challenges over recent years. Most notably, the building completed a mandatory Soft Story retrofit in 2021 (Tier 4), bringing it into compliance with San Francisco's seismic safety requirements. The property has also seen substantial commercial improvements, including the installation of ADA-compliant restrooms and accessibility upgrades in 2022-2024, along with various electrical and plumbing modifications. Recent maintenance includes the replacement of an exterior convenience staircase in May 2023. However, the building has experienced recurring issues with vacant commercial storefronts, evidenced by multiple complaints between 2018-2023. While most previous building violations have been resolved, there is an active violation from December 2018 regarding non-compliance with the Soft Story retrofit program and related requirements. The property has undergone periodic fire safety inspections and maintenance, with several violations noted between 2008-2021 related to alarm systems, sprinkler/standpipe systems, and extinguishers, though most have been corrected.

In terms of recent activity, the building has generated multiple 311 calls in early 2025 regarding garbage overflow issues near the property, with several cases marked as "Closed Case Resolved" and one currently "Open." The commercial portion of the property underwent antenna and radio equipment removal in 2015, and recent permits show ongoing improvements to electrical systems and accessibility features. The building's complex history includes periods of non-compliance with various city ordinances, particularly regarding vacant storefront monitoring, though many of these issues have been addressed through subsequent repairs and retrofits. The most recent building modification activity (2023-2024) has focused on accessibility improvements and routine maintenance, suggesting active management of the property by the owners.

Risk rating

How 9 Castle Manor Ave'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.
