Initial analysis

The two-unit residential building at 771-773 Grove Street in Hayes Valley, owned by Ian Armstrong, has undergone significant renovations and maintenance since its construction in 1890, with particular attention to both units over the past decade. Major improvements include substantial plumbing and electrical upgrades in 2019, including the installation of a new gas furnace, water heater venting, and comprehensive rewiring with new subpanel and extensive outlet installations. The property saw considerable interior remodeling in 2016-2018, featuring kitchen and bathroom renovations in both units, window and door replacements, and interior space reconfigurations. More structural work included foundation improvements in 2013 with the replacement of exposed U.R.M. brick foundation, though a voluntary structural reinforcement permit from 2016 was withdrawn.

The building's most recent maintenance activity includes electrical and plumbing final inspections completed in mid-2024, indicating ongoing attention to building systems. A notable incident occurred in 2023 when offensive graffiti was addressed by city services. Two fire-related incidents were recorded: one for a smoke detector activation and another for a carbon monoxide detector activation, though no actual fire or carbon monoxide was detected in either case and no civilian injuries were reported. Since 2023, there have been several 311 calls regarding street cleaning, graffiti removal, and other exterior maintenance issues, most of which have been promptly resolved by city services. The property appears to be well-maintained, with most recent building permits focused on completing previously started work, indicating attention to proper finishing and compliance of building systems.

Risk rating

How 771-773 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 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.
