Initial analysis

The two-unit, two-story residential building at 1243-1245 Grove Street in Alamo Square, constructed in 1923 and currently owned by Sato Family Living Trust, has undergone significant recent improvements and transitions. Most notably, the property is currently undergoing a condo conversion, with permits for electrical work and backflow prevention device installation obtained in 2024, following comprehensive upgrades in 2023 including the legalization of ground floor storage, utility rooms, and the installation of compliant handrails. The building has seen substantial interior renovations in 2022, including an in-kind kitchen remodel with updated appliances, cabinets, and plumbing, a split bathroom remodel, and the addition of a new 140 sq ft deck for the rear first-floor unit. Major infrastructure improvements were completed in 2008, including an electrical service upgrade to 200 amps, new breaker panels, and the installation of safety features such as arc fault circuits.

The property's maintenance history shows attention to safety and compliance, with building inspections and subsequent corrections being addressed promptly through multiple permits. A single building complaint was filed in 2016 regarding unauthorized construction of a stage for concerts in the backyard, though this complaint is no longer active. The property experienced three exterior issues in the surrounding area (graffiti and encampments) between 2017-2021, which were all resolved by city services. In an unusual event for the building's history, tenant buyouts occurred in August 2021, with compensation amounts of $22,242 for 3 tenants at 1245 Grove Street and $14,828 for 3 tenants at 1243 Grove Street, suggesting a coordinated transition of both units toward condo conversion. The most recent permit activity focuses on compliance with inspection reports and preparation for condominium conversion, indicating significant changes to the building's ownership structure and unit configuration.

Risk rating

How 1243-1245 Grove 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.

Neighborhood percentile

Out of 305 buildings in this neighborhood, 3 are predicted to be safer.
