The 72-unit residential building at 1820-1870 Post Street, constructed in 1978 and currently owned by GGA 1820 Post LP, has undergone significant maintenance and upgrade work throughout its history, with particular focus on infrastructure improvements in recent years. Most notably, in 2024, the building underwent extensive repairs including water heater installations across multiple buildings (1820, 1870, 1945 Sutter Street) in October, followed by drywall repairs, termite damage remediation, and HVAC system upgrades in December. The property has experienced several maintenance challenges requiring attention, including dry rot repairs to exterior balconies (completed November 2024), termite damage repairs in Unit 1901, and various plumbing system upgrades. A series of fire safety violations were issued in late 2023 regarding sleeping area requirements, though these were subsequently rescinded. The building has a documented history of moisture-related issues, with multiple complaints about water intrusion, window leakage, and mold formation between 2003 and 2021. Recent complaints from 2023 have addressed building security systems and property maintenance concerns, including a hoarding situation in one unit that was resolved by July 2023, as well as issues with the intercom/entry system. Multiple permits issued in late 2024 indicate ongoing efforts to modernize the building's infrastructure, including the installation of new heating systems and various structural repairs.

How 1820-1870 Post 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.
What the score means for you
Grade A–B — Low risk
DBI rarely finds violations here. Strong maintenance history and a clean complaint record.
Grade C — Moderate risk
Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
Grade D–F — High risk
Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
Out of 670 buildings in this neighborhood, 636 are predicted to be safer.
