Initial analysis

The three-story, two-unit multi-family residential building at 479-481 Clipper Street in Noe Valley, owned by Heather A O'Neill, has undergone significant improvements and maintenance since its original construction in 1900. The property has seen substantial recent investment, including a $25,000 kitchen remodel currently underway in Unit 481 (2024), following a series of kitchen and bathroom upgrades in 2022-2023 that included electrical panel upgrades (new 125-amp panel installed in garage for solar connection), solar panel installation (7.65 kW system with 18 PV modules), and comprehensive electrical work supporting modern amenities.

The building underwent major modifications in 2005-2006, including the addition of a first-floor unit with two bedrooms and two baths, and the installation of a new main panel with multiple subpanels to support the expanded electrical needs. The property has received consistent maintenance attention, with recent updates including a bathroom remodel in 2022 (tub-to-shower conversion), kitchen door replacement, and the installation of energy-efficient systems such as a ducted air source heat pump. Historical records show earlier improvements from 1997 to 2006 focused on structural and functional upgrades, including deck replacement and entry modifications. The building's recent permit activity, particularly the focus on energy efficiency (solar installation, heat pump), and ongoing maintenance suggests active property management and investment in modernization, though potential tenants should note the property's history of parking-related issues on Clipper Street, as evidenced by multiple parking enforcement requests between 2020 and 2024.

Risk rating

How 479-481 Clipper 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 1879 buildings in this neighborhood, 113 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.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

12-Month severity forecast
No violation 89.2%
Moderate concern 6.5%
Severe concern 4.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
