Rent & eviction protection

Is 684 Arguello Blvd 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 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.

15+ years since occupancy
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 two-story, four-unit multi-family residential building at 684 Arguello Blvd in the Lone Mountain neighborhood was constructed in 1964 and is currently owned by the David Lok Wong Living Trust. The building's maintenance record shows some significant structural work was performed in 1991 with underpinning construction along the south wall footing, and several older permits including a $10,000 streetspace permit from 2001 (now expired) and a reroofing project from 1993 (also expired). The property has undergone routine safety inspections by Housing Inspection Services in 2001, 2006, 2011, and most recently in 2016. A notable cluster of violations was documented in October 2001, including security-related issues such as inadequate primary locking devices at exterior doors and a lack of fire safety equipment, all of which were abated by January 2002.

Recent activity at the property has been relatively quiet in terms of building-specific issues, though there have been multiple 311 calls in the surrounding area between 2021 and 2025. These include reports of excessive noise (most recent in January 2025), graffiti (2024), illegal parking (2024), and general maintenance issues such as sidewalk cleaning needs and flooding (2021). Three fire incidents were recorded in the vicinity, categorized as a good intent call, public service, and a motor vehicle/pedestrian incident, none resulting in civilian injuries. While the building has had its share of historical violations and maintenance work, the most recent years show primarily external environmental issues rather than building-specific problems, though the most recent noise complaint from January 2025 is still open.

Risk rating

How 684 Arguello Blvd'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
38thpercentile

Out of 519 buildings in this neighborhood, 322 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.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.
