Initial analysis

The two-unit residential building at 279-281 Collingwood Street, owned by Happy Happy Homes LLC, is a two-story flats and duplex structure built in 1910 in the Eureka Valley/Dolores Heights neighborhood. The property has undergone several significant renovations over the past two decades, with the most recent major work occurring between 2015-2016, including kitchen and bathroom remodels in the main units and the removal of an illegal kitchen from the basement space to restore it as laundry. These improvements encompassed ceiling work, lighting upgrades, and plumbing updates, with costs totaling approximately $34,500. The building's HVAC system was upgraded with furnace and duct replacements in 2016 and 2018, and there have been three separate roofing projects completed between 1995-1998, indicating regular maintenance of major systems.

The property has experienced some neighborhood maintenance challenges, as evidenced by multiple 311 calls in recent years, including several reports of garbage and debris on or near the property between 2020-2024, though these were generally street-related issues rather than direct building concerns. There was one instance of hazardous materials (glass) reported in March 2021, which was resolved. The building's renovation history shows proper attention to building code compliance, including an official process to remove an illegal kitchen, though there were some address correction issues in 2016 that required multiple permits to resolve. The most recent building-related activity appears to be from 2018, with no major permits or renovations on record since then, though this may simply reflect the completion of major work rather than any problems with the building itself.

Risk rating

How 279-281 Collingwood 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 1278 buildings in this neighborhood, 332 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.

Construction spend, owner's portfolio

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

12-Month severity forecast
No violation 77.0%
Moderate concern 14.6%
Severe concern 8.4%
