Rent & eviction protection

Is 827-829 Fillmore 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 1900
2 or more units
4 units
Property type
Multi-Family Residential

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 1900
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 4-unit, 2-story multi-family residential building at 827-829 Fillmore Street in Alamo Square, owned by the Potente Family Revocable Trust, has undergone several significant modifications since its construction in 1900. Most recently, the property faced scrutiny for unauthorized short-term rentals, with the owner receiving violations for illegally operating units on Airbnb in 2019, which were ultimately resolved. A notable renovation occurred in 2012-2014, when substantial remodeling work was completed including the removal of bearing walls, bathroom relocations, and various updates to the units at a cost of approximately $45,000, along with a $19,850 reroofing project. The building's history includes multiple permits for roofing work (1998, 2014), and significant alterations dating back to the 1993-1995 period when a conversion from illegal apartment to storage was executed, along with modifications to basement fire sprinklers.

The property has faced several regulatory challenges, including a 2011 complaint regarding unpermitted construction and a 2015 investigation of a possible illegal unit. A series of building violations were recorded in 2007, primarily related to security and fire safety requirements, though these were abated within two months. The building underwent routine safety inspections in 2000, 2007, 2010, and most recently in 2018, with the 2007 inspection revealing multiple safety concerns that were subsequently addressed. Recent maintenance issues have included sidewalk defects due to tree roots (2019) and various sanitation matters, though these are primarily street-related issues rather than building-specific problems. The property has also experienced some unauthorized use issues, as evidenced by tenant buyouts in 2015 totaling $32,500 for two tenants, suggesting potential tenant displacement or unit conversion activities.

Risk rating

How 827-829 Fillmore 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
63rdpercentile

Out of 305 buildings in this neighborhood, 113 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.
