The property at 1443 47th Avenue in the Outer Sunset is a two-unit, two-story multi-family residential building constructed in 1913. The building has undergone numerous significant improvements and faced several serious issues in recent years. Most notably, a major active concern remains regarding unauthorized unit modifications, with violations filed in September 2015 citing multiple life/safety hazards including lack of required smoke detectors, unapproved wiring and plumbing, improper floor heights, and inadequate egress requirements.

The building also underwent important structural work in 2017, including roof repairs and floor re-supporting to address previous complaints, along with electrical system upgrades including a new panel installation and kitchen circuitry improvements. Recent improvements include the installation of a solar PV system completed in November 2023, indicating ongoing maintenance and modernization efforts by the owners. The property has experienced various maintenance and compliance issues over the years, including multiple violations related to unpermitted work (such as water heater and furnace installations), staircase repairs, and electrical system concerns.

While many historical violations have been resolved as of August 2019, several active complaints from 2015-2017 suggest continued monitoring may be necessary. Infrastructure improvements include a complete sewer line replacement in 2019 and various plumbing upgrades, demonstrating attention to basic building systems. The building's permit history shows consistent maintenance activity, with most recent work focusing on sustainability upgrades and routine repairs, though some older permits related to kitchen and bathroom renovations from 2016-2017 have expired, indicating possible non-compliance with proper permitting procedures.
