Rent & eviction protection

Is 4 Gerke Aly 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 property at 4 Gerke Alley is a 3-story, 4-unit multi-family residential building constructed in 1907, currently owned by Goggin Living Trust. The building has undergone several significant maintenance and improvement projects over the years, with particular attention to addressing safety concerns. Most recently, in 2017, there were repair works completed for dry rot on the deck ($1,200) and reroofing work ($6,200). There were multiple repair works in 2014 focusing on the backstairs, including a more substantial $8,000 repair of damaged treads and stringer. The building experienced water-related issues in 2016 that prompted urgent plumbing work, including the replacement of sanitary and storm drain piping ($3,000) and a house trap replacement, which was initiated following complaints from neighbors about water intrusion and drainage concerns. A notable historical compliance issue occurred in 2008 when multiple violations were recorded related to interior surfaces, including damaged walls, floors, and ceilings, though these were all abated by November 2008. The building underwent a significant interior renovation in 2009, including bathroom relocation, kitchen remodeling, and associated electrical and plumbing upgrades ($38,000).

The property has experienced several structural and maintenance issues over its history, including concerns about the rear stairs' condition, water damage, and electrical problems. There were three separate plumbing complaints in 2016 alone regarding drainage piping work, which were all resolved through appropriate permits. The most recent activity at the address has been limited to parking-related complaints in 2023-2024, with no significant building-related issues reported in recent years. Planning records indicate attention to proper permitting and compliance, particularly regarding a roof deck replacement, with clarifications about fire wall requirements and permit verification processes.

Risk rating

How 4 Gerke Aly'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
77thpercentile

Out of 684 buildings in this neighborhood, 157 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 age

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

Estimated permit spend (past 7 years)

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