Initial analysis

This two-unit residential building, located at 1142-1144 Treat Ave in San Francisco's Inner Mission neighborhood, is a 2-story flats and duplex structure built in 1906 and currently owned by Melissa Pieroni. Between 2018-2020, the property underwent significant renovations, including a substantial $115,000 remodeling project in 2018 that updated kitchens and bathrooms in both units and added new bathroom facilities. The building's infrastructure improvements included a complete foundation replacement in 2019 (from brick to concrete), installation of new HVAC systems with two furnaces and AC units, and comprehensive plumbing upgrades. The work resulted in multiple street space permits throughout 2019 and some construction-related complaints from neighbors regarding early morning noise, though these complaints do not currently appear active.

Recent records from 2024 show recurring issues with vehicles blocking driveways, with several citations issued in response to these incidents, though some calls resulted in "unable to locate" responses. The building's recent history suggests regular maintenance and updates, including a garage door replacement in 2019, though some plumbing and electrical permits from 2019-2020 show as expired or completed under different contractor arrangements. The property appears to be functioning as intended post-renovations, with no current active complaints in the building inspection division and no reported issues through the 311 system other than the parking-related incidents.

Risk rating

How 1142-1144 Treat Ave'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
95th percentile

Out of 2380 buildings in this neighborhood, 119 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 83.8%
Moderate concern 12.9%
Severe concern 3.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
