Rent & eviction protection

Is 749 21St Ave 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 1951

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 1951
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 two-story, five-unit multi-family residential building at 749 21st Avenue in San Francisco's Central Richmond neighborhood, owned by Leland Wong & Rosemary Lew, was constructed in 1951 and has undergone several notable maintenance activities. Most recently, in 2013, the building received a $15,000 reroofing project, though records show an earlier roofing permit from 1995 had expired. The building experienced significant safety-related violations in October 2002, when multiple fire safety and smoke detection issues were identified, including problems with the fire escape drop ladder, central alarm system, and smoke enclosure door closers. These violations were all addressed and abated by December 13, 2002. The property has had regular housing inspections, including a routine inspection in 2011, and while there have been numerous 311 calls regarding the property's vicinity between 2018 and 2021, most were related to parking enforcement issues with vehicles blocking driveways, along with a sewage backup incident in July 2020 that was promptly resolved. The building's documented history suggests that while it has experienced typical urban maintenance challenges, particularly in the early 2000s, these issues were addressed in a timely manner, with no active violations on record since 2002.

Risk rating

How 749 21St Ave'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
35thpercentile

Out of 2250 buildings in this neighborhood, 1462 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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.
