Initial analysis

The property at 31-33 Valley Street in Noe Valley is a four-story multi-family residential building constructed in 1900, containing two units owned by Lisa Adrienne Ells Irrevoc. The building has undergone significant renovations over the past decades, with the most substantial work occurring between 2010-2012 when the property underwent a major transformation from a 2-story to a 4-story duplex. This renovation included comprehensive updates to both units, installation of a new fire sprinkler system (58 heads), complete electrical system upgrade (200-amp service, new wiring), plumbing improvements (including 6 bathrooms and 2 kitchens), and the addition of a solar PV system. The 2010-2012 renovations totaled approximately $600,000 and included modernizing both units with updated living spaces, kitchens, and bathrooms.

Prior to these improvements, the building had faced several maintenance issues, including a housing inspection complaint in 2008 regarding broken windows, weatherproofing problems, plumbing issues, and heating concerns. There were also documented complaints about unauthorized construction work in 2009 and a permit violation involving shed demolition in 2008, though these issues were addressed and closed. The building's maintenance history shows regular attention to safety systems, with the installation of the comprehensive fire sprinkler system being a notable safety improvement. Recent history from 2021 onward shows recurring issues with vehicles blocking the driveway, as evidenced by multiple parking enforcement calls, though these are not directly related to building conditions.

Risk rating

How 31-33 Valley 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
47th percentile

Out of 1879 buildings in this neighborhood, 996 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 (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

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.

12-Month severity forecast
No violation 65.7%
Moderate concern 18.4%
Severe concern 16.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
