Rent & eviction protection

Is 3343-3345 Broderick 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.

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 two-unit residential building at 3343-3345 Broderick Street in the Marina district, owned by Jon & Kyung Swanson Family, is a two-story flats and duplex structure built in 1925. The property has undergone several significant maintenance and improvement projects over the past few decades, most notably including multiple roofing work attempts in 2019, with one permit valued at $12,000 being issued after a previously cancelled permit for $11,500. Other substantial improvements include a complete kitchen and bathroom remodel in 1989, basement wall reinforcement in 1990, installation of aluminum bedroom windows in 1992, new water heater installation in 2013, and a complete sewer line and housetrap replacement in 2007.

The building's infrastructure maintenance record shows attention to critical systems, with completed projects including plywood wall installation in the basement and structural improvements in 1990, as well as the most recent sewer repairs. Several 311 calls related to the property have been documented, with the most recent being in April 2023 regarding illegal postings. There were notable sewer-related issues in early 2013, involving two sewage backup incidents that required city response and were resolved. The property has experienced recurring tree root issues affecting the sidewalk, with documented cases in 2021 and 2018, though these were determined not to be directly affecting the building structure. The surrounding area has experienced typical urban maintenance issues such as street cleaning and parking concerns, all of which have been addressed and resolved through proper channels.

Risk rating

How 3343-3345 Broderick 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
71stpercentile

Out of 988 buildings in this neighborhood, 287 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.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.
