Rent & eviction protection

Is 2721-2723 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.

Built before 1979
Built 1906
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 1906
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 2721-2723 20th Street property, a two-unit residential building constructed in 1906 and currently owned by the Morales Revocable Living Trust, has experienced several significant maintenance and safety issues in recent years. The most serious concerns emerged in 2021, when multiple violations were documented between May and August, including electrical outlet repairs, smoke alarm compliance, sink repairs, skylight replacement, stair repairs, floor covering issues, and interior wall damage. These violations were eventually addressed through various permits, including a $30,000 renovation in July 2021 that involved kitchen cabinets, windows, stairs, and floor tiles. The 2021 complaints also raised concerns about heat issues, black mold in the kitchen, and allegedly illegal renovations, all of which were marked as not active by August 2022.

Earlier maintenance history shows multiple siding projects, with permits issued in 2003 for vinyl siding installation costing $14,000, and in 2018 for rear-side siding replacement at $8,000. More recent concerns, as documented through 311 calls in 2023, have included reports of encampments, medical waste, graffiti, and sidewalk-related issues, though these are external to the building itself. The most recent building inspection-related activity was a service request on 10/10/2021, which remains open according to 311 records. While there was a significant pattern of maintenance issues in 2021 that affected resident safety and comfort, most violations have been resolved through subsequent repairs and permit work, with particular attention paid to electrical, plumbing, and interior improvements.

Risk rating

How 2721-2723 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
8thpercentile

Out of 2380 buildings in this neighborhood, 2190 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
