Rent & eviction protection

Is 1139-1143 Lake 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.

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 1912
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 3-unit, 4-story multi-family residential building at 1139-1143 Lake Street, owned by the Dusanic Family Trust and built in 1912 in the Lake - The Presidio neighborhood, has undergone significant safety and system upgrades in recent years. Most notably, in early 2019, comprehensive fire safety improvements were completed including the installation of a new fire sprinkler system on the 4th floor with 18 heads, a 2-inch underground fire service, and a fire alarm monitoring system. The building has also seen substantial infrastructure improvements, including roof work with framing repairs ($30,000) in early 2019, and the installation of a solar power system (6.555 kW) in 2016.

The property has experienced recurring issues with heat and maintenance systems, with several permits for heating system upgrades and replacements between 2009 and 2019. A notable complaint from 2009 regarding inadequate heating was filed and resolved in 2010. There was also a complaint in 2017 regarding unauthorized window size modifications on the east property line of the top floor, which remains active as of October 2023. The building underwent routine housing inspections in 2001, 2008, and 2017, with multiple violations recorded in 2017 related to building safety requirements, including fire extinguisher provision and routine safety inspection access, though these violations were subsequently abated.

Risk rating

How 1139-1143 Lake 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
27thpercentile

Out of 660 buildings in this neighborhood, 482 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.

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.
