Initial analysis

The 15-unit, three-story apartment building at 550 14th Street in Mission Dolores, owned by Scarabosio Family Rev Trust, was constructed in 1928 and has undergone several significant improvements over the past decade. Most notably, it completed a mandatory soft story retrofit in 2016 at a cost of $100,560, and received major electrical system upgrades in December 2022 with the installation of a new 400-amp main service and 16-meter socket. Two fire-related violations were recorded and addressed between 2016 and 2023 regarding fire extinguishers and alarm systems, with the most recent fire complaint in 2022 being resolved. The building has experienced recurring electrical and safety issues, including a 2024 complaint about a dilapidated steel ventilation stack with falling debris hazard, and a 2021 plumbing issue involving sink backups and inadequate electrical outlets.

The property has undergone various unit-specific renovations, including comprehensive remodeling of units 104 and 105 in 2013 (kitchen, bath, windows, and electrical systems), and completed essential maintenance work such as roof replacement (2012) and stucco repairs (2012). Multiple building violations were issued in 2019 related to fire safety, lead paint hazards, and various maintenance issues, though these were all abated by August 2021. Recent 311 calls from 2024 have primarily concerned external issues such as graffiti and sidewalk cleaning, with multiple reports of garbage and debris needing attention. While the building has had its share of maintenance and safety concerns over the years, most documented issues have been addressed through proper channels, though some recent complaints suggest ongoing maintenance challenges.

Risk rating

How 550 14Th 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 799 buildings in this neighborhood, 655 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

12-Month severity forecast
No violation 20.2%
Moderate concern 50.2%
Severe concern 29.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
