The two-unit residential building at 423 Lawton St in San Francisco's Inner Sunset neighborhood has undergone several significant maintenance and improvement projects since its construction in 1905, with the most recent activity being a complete re-roofing project completed in April 2024 at a cost of $9,100. The property has seen substantial upgrades in 2014-2015, including a comprehensive kitchen and bathroom remodel, installation of new bathrooms, kitchen sink, washer/dryer, electrical service upgrade to 150 amps with two meters, and rewiring of multiple rooms, totaling approximately $70,000.

Important infrastructure work includes a house trap replacement and pipe work completed in 2020. The building's maintenance history shows regular attention to critical systems, with historical records indicating previous re-roofing work done in 1990. The property has experienced some infrastructure-related issues, including a sewage backup incident in 2009 and a missing side sewer vent cover in 2017, both of which were resolved.

There are several 311 calls on record, with the most recent being a sidewalk defect related to tree roots (opened in August 2024) and a Christmas tree disposal issue (January 2025). While the building has required various exterior maintenance work over the years, the permits and service records suggest ongoing attention to building systems and infrastructure. The property's permit history indicates regular investment in both maintenance and modernization, particularly during the 2014 improvement period when multiple systems were upgraded simultaneously.
