Rent & eviction protection

Is 145 6Th 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 1904

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 1904
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 apartment building at 145 6th Avenue, owned by the Wiederhold Family Trust, was constructed in 1904 and has undergone significant maintenance and upgrades over the past two decades. Most recently, in 2019, the building received both a new roof ($50,212) and solar panel installation (7.56 kW system), along with electrical upgrades including the replacement of the Apartment #1 panel and main breaker. The building underwent substantial foundation work in 2002, with multiple sections of the structure receiving attention, including the east, south, north, west, and right-side foundations. A series of building violations were recorded in 2004 related to fire safety, security, and structural issues, including problems with fire escapes, smoke detectors, and fire sprinklers, though all were resolved by February 2005. The property has maintained regular housing inspections, with the most recent routine inspection occurring in 2015. Historical complaints from the 1990s indicated various maintenance issues, including water damage and plumbing problems, but these appear to have been addressed in subsequent years.

The building's recent maintenance record demonstrates active upkeep, with significant investments in both safety improvements (fire safety compliance in 2005, solar installation in 2019) and structural maintenance (roof replacement in 2019). The property has experienced recurring issues with parking violations and tree damage in the surrounding area, as evidenced by multiple 311 calls between 2019-2023. However, these external matters are separate from the building's internal conditions. The property's comprehensive foundation work in 2002, addressing multiple structural elements, suggests a strong commitment to maintaining the building's core infrastructure.

Risk rating

How 145 6Th 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
29thpercentile

Out of 660 buildings in this neighborhood, 469 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.

Estimated permit spend (past 7 years)

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