Initial analysis

The property at 78 Mars Street in Corona Heights is a two-unit, two-story multi-family residential building constructed in 1906, currently owned by the Stinson Weiss Family Living Trust. Over the past decades, the building has undergone several significant renovations and improvements, with the most recent major work occurring between 2020-2021, including a third-story interior remodel with kitchen and bathroom updates ($50,000), sewer lateral replacement, and associated plumbing and electrical work. The building has seen consistent maintenance and upgrades, including multiple window replacements (most recently in 2018 with Marvin wood and Milgard fiberglass windows), kitchen and bathroom renovations (2003 and 2020), and infrastructure improvements such as a 200-amp electrical service upgrade and the installation of 12 rooftop solar panels in 2012.

Historical records show some construction-related issues in 2001 regarding a retaining wall and deck work that prompted a building complaint, though this violation was abated in early 2002. The property has maintained active compliance with permits and generally demonstrates regular upkeep. Recent 311 calls (2022-2024) have primarily related to external matters such as parking issues, sidewalk graffiti, and street maintenance, rather than building-specific concerns. The most recent building permits and improvements suggest ongoing investment in the property's maintenance and modernization, particularly focusing on interior spaces and energy efficiency features.

Risk rating

How 78 Mars 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
93th percentile

Out of 348 buildings in this neighborhood, 24 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.

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 85.7%
Moderate concern 10.7%
Severe concern 3.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
