Initial analysis

The three-story multi-family residential building at 3379-3381 21st Street, owned by Green Hills Views LLC, has undergone significant modifications since 2018. The property, constructed in 1909, consists of two units and has experienced several major renovations, including the installation of a comprehensive fire sprinkler system with 87 heads throughout the building in 2019-2020 (costing approximately $70,000 for both labor and equipment), followed by extensive interior remodeling in 2018-2023. Recent unauthorized modifications in unit 3381 led to a violation notice in 2021, citing unpermitted changes including bathroom additions and bedroom conversions, which the owner has attempted to rectify through subsequent permits in 2023-2024. The building has faced scrutiny regarding alleged illegal rooming/boarding house practices, with complaints about unauthorized room rentals, though this violation was marked as "Not Active" in October 2023.

The property underwent substantial improvements in 2018-2019, including complete plumbing renovations for multiple bathrooms, kitchen, and laundry facilities, along with electrical system upgrades. A recent complaint filed in January 2025 suggests ongoing concerns about unauthorized construction work and potential permit violations, though this case is still active. While there have been several 311 calls regarding the property, primarily related to street issues and noise, there have been no recorded fire incidents or civilian injuries associated with the building. The property's extensive renovation history, including multiple permit modifications and compliance efforts, indicates an ongoing process of updating and maintaining the building to meet modern safety and living standards, though with some challenges regarding unauthorized modifications and building code compliance.

Risk rating

How 3379-3381 21St 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.
