Rent & eviction protection

Is 25-27 Blanken 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.

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.

Built 1932
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 property at 25-27 Blanken Avenue is a two-story, three-unit multi-family residential building located in the Little Hollywood neighborhood, constructed in 1932 and currently owned by Jpt Associates, LLC. The building's most significant event on record occurred in 2008 when it sustained fire damage requiring substantial repairs to the west side's roof structure, exterior wall, and floor joists, with permits showing a $12,000 residential repair and an additional $4,000 related to a bar area. That same year, the property underwent several infrastructure improvements including extensive roofing work ($20,000), the installation of plumbing fixtures (two bathrooms, two kitchen sinks, and one commercial restroom), and electrical work involving the installation of lighting and receptacles on the ground floor.

In recent years (2023-2024), the building has generated several 311 calls primarily related to street maintenance and regulatory issues rather than direct building concerns. These include reports of garbage and debris (April-June 2024), illegal postings (May 2024), defaced street cleaning signs (January and May 2023), and parking enforcement matters (abandoned vehicles and illegal parking). The most recent building-related incident was a fallen tree reported in January 2024, which was resolved through street and environmental services. While the property has undergone necessary repairs and improvements in the past, there are no recent building permits or major structural issues on record, suggesting that the building has maintained stability since the 2008 repairs.

Risk rating

How 25-27 Blanken 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
85thpercentile

Out of 7 buildings in this neighborhood, 1 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building age

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

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.
