Initial analysis

The property at 80-82 Harriet Street is a two-unit, two-story multi-family residential building located in San Francisco's South of Market neighborhood. Built in 1911 and currently owned by Stuart and Amanda Collins, the building has undergone significant improvements and maintenance work over recent years. The most notable current project, filed in May 2023, involves the construction of a new roof deck with planters, benches, and solar panels, along with stair improvements for access. The building has also received substantial electrical upgrades in 2023, including the installation of a heat pump water heater and EV charger outlet, as well as plumbing and bathroom renovations in 2021. Multiple permits from 2021 show efforts to finalize previous ongoing projects, particularly concerning the rear unit's kitchen and bathroom installations.

The building's maintenance history shows attention to safety systems, though there have been some periodic fire safety concerns. A September 2023 violation was issued regarding the sprinkler/standpipe systems, following earlier issues in 2017 and 2021. The property has experienced several elevator-related incidents and false alarm activations over the years, but notably, there have been no civilian injuries reported from any incidents. Recent 311 calls indicate some neighborhood challenges, including encampments and sidewalk maintenance issues, though these are not directly related to the building's condition. The property's various permits and improvements suggest active management and upkeep, with particular emphasis on modernizing systems and complying with current codes, including a rear yard variance approval to construct the new deck and stairs within the required rear yard.

Risk rating

How 80-82 Harriet 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 430 buildings in this neighborhood, 17 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 87.6%
Moderate concern 10.4%
Severe concern 2.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
