Rent & eviction protection

Is 3321 21St St rent-controlled?

San Francisco's Rent Ordinance caps rent increases and provides eviction protection for most residential units built before 1979 with 2+ units. Here's how this building scores.

Built 1904

Statewide backstop · AB 1482

California Tenant Protection Act of 2019

Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.

15+ years since occupancy
Built 1904
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Local rent control likely takes priority. This building appears to fall under the local ordinance above, which is stronger than AB 1482. Where a local just-cause ordinance applies, its rules govern instead of the state cap.

AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.

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

Lower risk — safer than most nearby

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
0thpercentile

Out of 1278 buildings in this neighborhood, 1278 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
