Rent & eviction protection

Is 3356-3358 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 before 1979
Built 1900
2 or more units

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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 1900
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 property at 3356-3358 21st Street is a two-unit, two-story multi-family residential building located in the Eureka Valley/Dolores Heights neighborhood, constructed in 1900. The building has experienced recurring maintenance issues, particularly with the rear stairs, which have required multiple repairs over the years (2003, 2012, and most recently in 2024). A significant recent concern is the documented mold problem reported in January 2023, which was noted as affecting every room in the house and had not been adequately addressed after tenant notification. More recent permits indicate ongoing maintenance work, including a basement ceiling repair, window glass replacement, and stair repairs totaling $29,000 in 2024, as well as a completed reroofing project in 2023 costing $18,000.

The building has a history of various violations and complaints, particularly between 2002-2003, when multiple fire safety and maintenance issues were documented, including problems with the fire escape, stairs, drainage pipes, and combustible storage. These violations were ultimately abated by March 2003. More recent concerns include a July 2024 complaint about an unsafe back porch and an active general maintenance complaint from February 2024. The property has undergone several infrastructure improvements, including an underground electrical service conversion in 2004 and various repairs to address building code compliance issues. Historical maintenance records show regular upkeep, including re-roofing work, stair repairs, and window replacements, though some past complaints about sanitation issues and graffiti have been recorded through 311 calls. The current ownership under Shirley Dang has maintained the property through various repairs and improvements, with recent focus on addressing water damage and fire safety concerns.

Risk rating

How 3356-3358 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
12thpercentile

Out of 1278 buildings in this neighborhood, 1125 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

NOV rate, owner's portfolio
