Rent & eviction protection

Is 806 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.

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.

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-unit residential building at 806 Arguello Blvd, located in the Lone Mountain neighborhood, is a two-story flats and duplex structure built in 1904 and currently owned by the Elizabeth Mun Yip Trust. The property has undergone several significant improvements over the past decades, including a reroofing project completed in 2013 ($3,500) and a window replacement project in 2012 ($9,000) that involved installing 18 new vinyl windows not facing the street, along with repairing six steps at the lightwell. In 1996, modifications were made to legalize two habitable rooms and a toilet on the ground floor.

The building's history includes several concerning issues that potentially impacted resident safety and comfort, particularly in the late 1990s. A 1997 housing inspection revealed problems with the electrical system (blowing fuses), inadequate heating, and bathroom floor deterioration, while a 1995 complaint about an illegal basement unit was filed. A plumbing complaint regarding a rusty gas pipe was reported in 2007, though it was quickly abated within one day. More recently, there has been one fire incident on record where an alarm system malfunctioned, with no civilian injuries reported. The property has experienced occasional issues in the surrounding area, including multiple instances of sidewalk parking violations (with at least three citations issued), graffiti incidents, and a loose garbage complaint in early 2024, though most of these external issues have been promptly resolved by the relevant authorities.

Risk rating

How 806 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
56thpercentile

Out of 519 buildings in this neighborhood, 228 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.

Building age

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

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

Estimated permit spend (past 7 years)

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