Rent & eviction protection

Is 2844 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 1964
2 or more units

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 1964
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 2844 21st Street, built in 1964 and currently owned by 21st Street LLC, has undergone several significant structural and safety improvements over recent years. Most notably, the property completed a mandatory soft-story retrofit in 2017 (Tier 3), addressing seismic safety requirements. The building has experienced recurring issues with moisture damage, as evidenced by multiple repairs to balconies and facades due to dry rot, including a significant $40,000 repair in 2022 to address stucco and siding issues on the west and south facades. A serious safety concern was documented in May 2021 when a top-floor balcony separation was reported, leading to emergency repairs and the replacement of Juliet balconies.

The property has faced various maintenance and safety challenges over the years, including recent fire safety violations in May 2024 regarding alarm systems and extinguishers, though these were promptly corrected. Previous concerns include kitchen and bathroom maintenance issues in 2012, followed by a series of complaints in 2008 related to mold, heat, and window problems. Unit 302 received a comprehensive renovation in 2020, including kitchen and bathroom remodeling with updated plumbing and electrical systems. The building's exterior has required ongoing maintenance, as shown by multiple siding repairs and weather-related improvements, including a complete reroofing in 2016. Numerous 311 calls have been logged in recent months (2024), primarily regarding street cleaning and debris issues on the property boundaries.

Risk rating

How 2844 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
5thpercentile

Out of 2380 buildings in this neighborhood, 2261 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.
