Initial analysis

The 12-unit apartment building at 3321 21st Street, owned by the Hanumandla Reddy Family Revocable Trust, was constructed in 1904 and is classified as a two-story multi-family residential building. The property has undergone significant improvements in recent years, including a completed mandatory soft-story retrofit in 2019 (Tier 3) costing $120,000, with subsequent revisions in 2023. The building has received substantial unit improvements, including comprehensive remodels of units 3, 4, 6, 8, 11, and 12 between 2012 and 2015, featuring kitchen and bathroom upgrades. More recently, in late 2023, new hot water boiler and steam boiler systems were installed, though these installations prompted multiple complaints in September-October 2023 regarding no heat, water issues, and ventilation problems, which were subsequently resolved.

The building has experienced several maintenance and safety issues in recent years, with notable concerns including multiple active violations from 2017 related to smoke alarms, lead hazard warnings, exterior painting, and garbage receptacle placement, all of which were referred to a Director's Hearing in February 2023. There have been recurring fire safety concerns documented through fire complaints between 2019 and 2023 regarding alarm systems and extinguishers, though most were marked as Condition Corrected or No Merit. The property also faced challenges with its heating systems, as evidenced by multiple complaints about boiler permits in 2022-2023, and more recent complaints in October 2023. An illegal banner installation and unauthorized basement office space construction were investigated, though the banner violation was abated. While the building has had its share of maintenance issues, many appear to be being addressed through recent repairs and improvements, particularly regarding seismic safety and unit modernization.

Risk rating

How 3321 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.
