Initial analysis

The two-unit, two-story multi-family residential building at 1851-1853 Church Street in Glen Park, built in 1916 and currently owned by the Ariano Lembi Trust, has undergone several significant improvements in recent years. Most notably, the property is currently undergoing an installation of a comprehensive solar and energy storage system, including 15 roof-mounted solar PV modules and a Tesla Powerwall+ battery system, with associated permits completed as of May 2024. This follows several substantial renovations since 2012, including a kitchen remodel (2013) with window and door replacements, bathroom renovations on both levels (2012-2014), and a complete reroofing (2016). The building has also seen significant infrastructure upgrades, including gas line reroutes, plumbing improvements, and electrical system enhancements.

The property has experienced recurring sewer issues, with documented sewage backup incidents occurring in November 2023, March 2021, January 2018, November 2018, and November 2016, all involving 4-inch vent issues and requiring PUC Sewer Operations intervention. The building's exterior and surrounding infrastructure have received attention, with a tree maintenance request (August 2023), a sidewalk defect report (November 2018), and multiple parking enforcement cases being recorded. While the sewer issues represent the most consistent maintenance challenge for the property, recent improvements suggest ongoing investment in building systems and infrastructure. The most recent building improvements focus on sustainability and modernization, with the solar and battery system representing the latest in a series of infrastructure upgrades that have occurred over the past decade.

Risk rating

How 1851-1853 Church 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
88th percentile

Out of 364 buildings in this neighborhood, 44 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.

Building age

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

Estimated permit spend (past 7 years)

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

12-Month severity forecast
No violation 85.2%
Moderate concern 11.6%
Severe concern 3.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
