3655 Broderick St

Marina, SF 94123 0915001 18 units · 3 fl · 1936

Nothing on record for this building in the last seven years, but our model still flags a rising risk of maintenance problems in the next 12 months. That forecast comes from the owner's wider portfolio and the surrounding area, not from this building's own record — treat it as a reason to ask questions, not as evidence of a problem. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

The bar and the rating point different ways because they measure different things: the bar counts DBI violations already on file, the rating forecasts the next 12 months.

Rent & eviction protection

Is 3655 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 18-unit, three-story multi-family residential building at 3655 Broderick Street, owned by the Keighran Family Living Trust, was constructed in 1936 and has undergone several significant infrastructure upgrades over the years. Most notably, in 2024, the building completed a substantial fire alarm system upgrade to meet current safety codes, following a pattern of continuous attention to fire safety which includes recent fire alarm maintenance in September 2024 and previous improvements in 2018, 2022, and 2009. The building's heating system was modernized in 2014 with the installation of a new Peerless steam boiler, and the electrical infrastructure received a significant upgrade in 2004 with the installation of a new 600-amp service.

The building has a history of routine safety inspections, with the most recent occurring in 2023-2024, which revealed a sleeping area requirement violation that has since been abated. A cluster of violations was documented in February 2016, including issues with fire proofing, fire escape maintenance, and the installation of safety equipment, though these were all abated by May 2016. The property has experienced two fire-related incidents since 2009: one involving a carbon monoxide detector activation (with no CO detected) and another related to elevator rescue, neither resulting in civilian injuries. Recent inspections of the building's fire safety systems have shown a consistent pattern of required corrections followed by successful resolution, demonstrating ongoing maintenance of safety standards. The building's history includes typical urban residence issues such as parking violations and graffiti removal requests, with all such issues being addressed through appropriate channels.

Risk rating

How 3655 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
10thpercentile

Out of 988 buildings in this neighborhood, 889 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.
