The building has undergone significant Improvements including foundation repairs in 2011 ($20,000), reroofing in 2009 ($8,200), and multiple interior updates such as kitchen cabinet installation in 2013 ($5,000) and bathroom remodeling in 2012.

The property's systems have been updated over time, with gas line extensions completed in 2019 and electrical improvements including a new 200-amp panel installation in 2012. Historical records show some permit-related issues in 2001 when there were unauthorized construction activities that led to several complaints and violations, though these were resolved by 2001-2002. More recently, there have been multiple reports of overflowing city garbage cans in the vicinity between October and December 2024, though these are external to the building itself and have been marked as resolved. The building's maintenance history shows regular upkeep and improvements, with only one active building complaint related to unpermitted window work as of March 2024.

Risk rating

How 26-28 Twin Peaks Blvd's risk score is calculated

What the score means for you

Grade A–B — Low risk

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.
