Rent & eviction protection

Is 3329-3333 20Th 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.

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.

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 three-story, 10-unit multi-family residential building at 3329-3333 20th Street in San Francisco's Inner Mission neighborhood, owned by Meda Small Properties LLC, has undergone significant renovations and faced various maintenance challenges since its construction in 1900. The property has seen extensive improvements between 2017 and 2019, including voluntary structural improvements ($148,000), complete remodeling of all units, ADA accessibility modifications, and the installation of a new fire alarm system ($25,000). Between 2017 and 2018, all units received electrical upgrades, and substantial plumbing work was performed, including kitchen and bathroom remodels, and replacement of sewer lines, water main, and gas lines.

Of particular note is the building's fire safety history, with multiple fire alarm system issues documented between 2005 and 2024, including a recent violation in January 2024. Historical complaints from 2000-2001 revealed serious maintenance issues at that time, including sanitation problems, interior surface violations, and heating system failures, though these appear to have been addressed. The most recent complaint, filed in September 2023, regarding common areas, is currently active. There have been several instances of building quality control issues in recent years, including multiple 311 calls in 2023-2024 related to general cleaning, graffiti, and sidewalk conditions. The building has also experienced periodic plumbing issues, with complaints about slow drains and standing water noted in 1997, and a sewage incident reported in 2001. While most historical violations and complaints have been resolved, including past problems with pests, lighting, and various infrastructure systems, the building's maintenance history shows a pattern of ongoing attention required for fire safety systems and regular upkeep of common areas.

Risk rating

How 3329-3333 20Th 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
11thpercentile

Out of 2380 buildings in this neighborhood, 2118 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
