Initial analysis

The three-unit multi-family residential building at 877-879 De Haro St in Potrero Hill, owned by Gerald J & Tricia A Probert, has undergone significant improvements and faced several maintenance challenges since its construction in 1925. Most recently, in 2023, the property received substantial upgrades with the installation of three solar photovoltaic systems, including a 5.525 kW system in July and a smaller 2.55 kW system in April, reflecting the owners' commitment to sustainable energy. The building's recent maintenance history shows attention to basic upkeep, including a complete reroofing project in 2022 costing $8,000.

The property has experienced several infrastructure issues over the years, with the most pressing current concerns being a collapsed sidewalk reported in June 2022 and tree roots lifting the sidewalk reported in January 2021, both of which remain open cases with the Department of Public Works. Historical records from the late 1990s show multiple renovation projects, including interior remodels, furnace installation, and deck construction, suggesting significant past investment in building improvements. Planning records indicate previous attempts to legalize an existing second dwelling unit without necessary parking, and there was a resolved issue regarding illegal short-term rentals at 879 De Haro St. The building's utility infrastructure has received attention, with multiple electrical and plumbing permits issued in the 1990s, though some permits from that period expired. Recent infrastructure issues have included two separate streetlight problems in 2017 (one flickering and one burnt out) and a flooding incident related to street sewer systems.

Risk rating

How 877-879 De Haro 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 726 buildings in this neighborhood, 450 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 location

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

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Number of floors

Building height affects maintenance complexity and is one of the size signals the model uses.

12-Month severity forecast
No violation 55.6%
Moderate concern 31.2%
Severe concern 13.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
