Rent & eviction protection

Is 3650 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.

Built before 1979
Built 1929
2 or more units

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 15-unit, 3-story multi-family residential building at 3650 Broderick Street in the Marina district, built in 1929 and currently owned by Richard Woo, has undergone several significant safety system upgrades and faced multiple regulatory challenges over its history. Most notably, in 2024, the building received a completed fire alarm system upgrade costing over $51,000 to comply with San Francisco Fire Code requirements, following a previous cancelled permit for a similar upgrade with additional features. The building has a documented history of boiler permit violations, with complaints filed in 2006, 2010, and 2018 regarding unpermitted boiler operations, though these were all eventually abated. More recent maintenance work includes a water heater replacement in 2017 and boiler replacement in 2015, both properly permitted.

The building experienced two concerning incidents in May 2020, during the COVID-19 pandemic, involving allegedly unsafe paint removal work and lead paint concerns, though these complaints were later marked as not active. Fire safety has been an ongoing focus, with multiple fire system complaints and violations, including issues with alarm systems and extinguishers in 2009, 2017, and 2024, all of which were eventually corrected. The property has undergone various infrastructure improvements over the years, including sidewalk repairs in 2001, dry rot repairs in 1996, and storage room modifications in 1989. Recent records from 2023-2024 show multiple parking-related complaints near the property, though these are not directly related to building safety or maintenance. The building's utility infrastructure was updated in 2013 with the installation of a new antenna and electric box on an existing pole by Extenet.

Risk rating

How 3650 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
8thpercentile

Out of 988 buildings in this neighborhood, 909 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.

Neighborhood location

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