AI summary

The 511-515 Vallejo Street building is a 3-story, 6-unit multi-family residential property constructed in 1913 in the Telegraph Hill neighborhood. The property has experienced several significant maintenance and compliance issues in recent years. Most notably, there is an active violation regarding the mandatory Soft Story Retrofit Program, with Tier 3 non-compliance status as of September 2019, and related monthly monitoring fees. The building has also faced recent plumbing challenges, with multiple sewage backup incidents reported in 2024, including a broken house trap issue documented in September 2024, though this has since been repaired. Historical records show various renovation and improvement efforts, including electrical upgrades in 2015 (225-amp service upgrade) and 2018 (bonus room rewiring), roof room repairs in 2018, and plumbing work in 2015 involving kitchen and bathroom remodels in two units.

The property's maintenance history reveals a mix of completed and incomplete projects, including a cancelled permit from 2017 that would have added an ADU to the first floor. Multiple street space permits have been issued between 2017-2018, and several plumbing permits have been processed, including work to obtain final inspections for prior expired permits. The building has undergone various routine inspections over the years, with some findings related to fire safety and maintenance requirements, though many of these earlier violations were marked as not active. Recent infrastructure work includes the replacement of the house trap in 2024 to address compliance issues. The property has had recurring issues with its sewer system, as evidenced by multiple 311 calls in 2024 regarding sewage discharge from the side sewer vent, suggesting potential ongoing challenges with the building's plumbing infrastructure.

Risk rating

How 511-515 Vallejo St's risk score is calculated
