Initial analysis

The property at 4139-4141 Anza Street in the Outer Richmond district is a two-unit, two-story multi-family residential building constructed in 1948, currently owned by the Lee Family Revocable Trust. The building has undergone significant improvements and modernization efforts in recent years, with the most recent work being completed in September 2024 involving a $11,500 reroofing project. Major safety upgrades were implemented in 2022, including the installation of a comprehensive fire sprinkler system covering the ground floor, complete with a new monitoring system, which represented a substantial investment of over $25,000. The building underwent substantial interior improvements in 2021, including the conversion of closets into full bathrooms on the second and third floors, and a significant renovation of the exit passageway to enhance safety features. In 2017, the property achieved a notable milestone with the legalization of a formerly illegal ground floor dwelling unit, complete with a new 200-amp electrical service and four meters to accommodate the building's units.

The building's maintenance record shows attention to exterior upkeep, with rear siding replacement and various plumbing and electrical upgrades completed systematically over the past few years. While there was one building complaint filed in 2017 regarding unauthorized basement construction, this complaint is currently listed as not active. The property has experienced recurring parking-related issues in the vicinity, with multiple 311 calls between 2020 and 2024 regarding vehicles blocking driveways and parking on sidewalks. However, these parking enforcement issues, though frequent, are external to the building itself and relate to public street conditions rather than the property's management or maintenance.

Risk rating

How 4139-4141 Anza 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.

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.

Director's hearing rate, owner's portfolio

Per-building rate of director's hearings across the owner's portfolio.

12-Month severity forecast

Moderate concern 7.3%
Severe concern 1.7%
