Initial analysis

The property at 331-333 West Portal Avenue is a two-story mixed-use building constructed in 1933, containing three residential units and ground-floor commercial space. Recent significant changes include the conversion of the former retail space to a community facility, now operating as The Coder School, completed in 2023 with accessibility improvements including a new ramp and restroom modifications ($30,000), followed by additional revisions in early 2024 ($20,000). The building underwent substantial residential improvements in 2022, including a $110,000 renovation of Unit A featuring kitchen and bathroom updates. The property has maintained basic safety systems with regular upgrades, including a new heat pump and air handler installation in 2024, followed by comprehensive electrical and plumbing work to support the recent renovations.

Historical records show proper attention to security issues, with an aluminum storefront replacement in 2015 following a break-in incident. The building has experienced typical urban maintenance issues, with various sidewalk and curb repairs documented between 2022-2023, and three minor 311 calls regarding public space maintenance in 2024. While the property has recorded two gas-related emergency responses in previous years, neither incident resulted in civilian injuries. The building's recent transformations demonstrate regular maintenance and adaptation to changing uses, with proper permitting and safety upgrades to meet contemporary standards.

Risk rating

How 331-333 West Portal Ave's risk score is calculated
