Initial analysis

The three-story multi-family residential building at 949-951 Valencia Street in San Francisco's Inner Mission district, built in 1916, contains 4 units plus ground-floor commercial space. The property has undergone significant recent improvements, including the installation of solar panels (11.6 kW system) in 2018, and the replacement of water heating systems in 2023 (both electric water heater installation and reconnection work). A reroofing project was completed in 2016 at a cost of $12,600. The building has maintained active compliance with routine safety inspections, with recent inspections in 2015 noting various issues including the need for smoke detector improvements and combustible storage concerns, all of which were subsequently addressed.

Historical records show a series of maintenance and improvement projects, including foundation work, bathroom renovations, and electrical systems upgrades in the mid-2000s. The property experienced several violations in 2003 related to building safety, including issues with stairs, handrails, ceilings, and smoke detectors, which were all resolved by January 2004. More recent building complaints have been limited to a vacant storefront issue in 2023, while various 311 calls in 2020-2024 primarily relate to external matters such as graffiti, street cleaning, and parking meter maintenance. The building's systems have been regularly updated, including significant electrical infrastructure work in 2007 for the commercial space and plumbing improvements including the installation of multiple sinks and a new water heater in 2007.

Risk rating

How 949-951 Valencia 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.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
