Initial analysis

The 3-unit multi-family residential building at 4 Culebra Terrace in Russian Hill, owned by the Chew/Chen Family Trust, has undergone several significant maintenance and improvement projects since its construction in 1913. The most recent work, permitted in August 2024, involves the replacement of two kitchen windows facing the alley. The property has seen substantial upgrades to its infrastructure in recent years, including plumbing improvements with the replacement of a broken sewage line (2020) and two complete furnace replacements (2018-2019), demonstrating ongoing maintenance of essential systems. A notable set of improvements occurred in 2015-2016 following a physical inspection report (CC-7950), which included electrical upgrades, deck repairs, and window replacements.

The building's history shows attention to both aesthetics and structural integrity, with projects such as the 2018 concrete retaining wall replacement and the 2016 front facade window restoration to restore historic character. While there were some water-related issues in the early 2000s (2002-2003) regarding seepage through stairs and backyard areas, these appear to have been resolved, with no similar complaints in recent years. The property has undergone regular routine inspections by Housing Inspection Services in 2004, 2006, and 2011, all of which were documented as completed and resolved. Recent maintenance activity suggests proactive management, with multiple permits issued for various improvements, including the most recent kitchen window replacements and ongoing attention to plumbing and HVAC systems. The building's historical planning records indicate previous proposals for garage construction and window replacements, with varying outcomes, though these appear to be in reference to a different address (1246 Lombard Street) which may be related to the same ownership group.

Risk rating

How 4 Culebra Ter'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.
