Initial analysis

The 16-unit apartment building at 160 Portola Drive in Twin Peaks, built in 1965 and owned by the Paratore Estate, has undergone several significant improvements and faced various challenges over the years. Most notably, a comprehensive fire safety upgrade was completed in April 2024, costing $42,025, which included the installation of low-frequency sounders in each unit, new pull stations, an addressable fire alarm control panel, and a cellular dialer. The building successfully completed its mandatory soft-story retrofit in 2016-2017, demonstrating compliance with seismic safety requirements. Recent improvements in 2024 included the replacement of electrical panels in multiple units (105, 104, 205, 301, 304, 106, 302, 305, 204, and 203) for insurance compliance, and the completion of various maintenance works such as rear stair repairs and column reinforcements in 2020.

The building has experienced recurring maintenance issues and safety concerns over its history. In October 2020, multiple serious violations were documented, including problems with the floor covering, fire escape ladder, rodent infestation, staircase repairs, and various smoke detection requirements, though these were all abated by December 2020. More recent safety concerns emerged with a sleeping area requirement violation issued in December 2023. The building's history includes past complaints about water damage, electrical issues, and management responsiveness between 2002-2008, as well as various exterior maintenance matters. The property has been actively maintained in recent years, with multiple units receiving new patio doors (2019-2021) and a mini-split system installation in 2019, suggesting ongoing investment in building improvements. Recent 311 calls have primarily related to street cleaning and waste management rather than building-specific issues.

Risk rating

How 160 Portola Dr'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

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.

Building size

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

Number of units

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

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 23.8%
Moderate concern 61.6%
Severe concern 14.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
