Initial analysis

1821 Cabrillo Street is a three-story multi-family residential building constructed in 2001, currently classified as a Flats & Duplex property with two legal units. The building's history has been marked by numerous permit applications and violations related to unauthorized unit conversions and modifications. Most recently, in June 2024, a permit was filed to add a kitchen to the first floor to create an ADU, which follows a pattern of attempts to establish additional dwelling units in the building. Significant enforcement actions occurred between 2008 and 2020 regarding unauthorized unit conversions, including a 2008 violation for an illegal ground floor unit with unapproved construction, plumbing, and electrical work, and a 2019 violation concerning an illegal fourth-floor kitchen and unauthorized modifications. These violations resulted in multiple permits for restoration work, including a completed permit in 2020 to remove the illegal fourth-floor kitchen and restore the original stair entrance. The building has also undergone several maintenance improvements, including a 2017 permit for replacing siding on the back and left sides with hardie plank siding.

The property has experienced various residential quality challenges over the years, particularly in 2008 when multiple complaints documented mold, pest infestations, and plumbing issues, all of which were subsequently abated. Fire safety records show minimal incidents, with the most notable being two alarm system activations in 2006 and 2007, one of which resulted in corrected conditions. Recent records from 2024 primarily consist of parking enforcement and waste management issues, including reports of toters being left out and illegal parking, which are generally not significant concerns affecting resident safety or building integrity. The current status of the building shows ongoing efforts to comply with ADU regulations, though the history of unauthorized modifications suggests careful attention should be paid to future changes and their impact on unit legality and building systems.

Risk rating

How 1821 Cabrillo 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

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.

Notices of Violation, owner's portfolio

DBI NOVs across all buildings this owner is registered on — a signal of systemic maintenance issues across the portfolio.

12-Month severity forecast
No violation 90.6%
Moderate concern 7.0%
Severe concern 2.4%
