Rent & eviction protection

Is 3239 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.

15+ years since occupancy
Built 1928
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-story multi-family residential building at 3239 Broderick Street, owned by 3239 Broderick Street LLC, was constructed in 1928 and contains four apartment units. The property has undergone several significant improvements over the past decades, with the most recent major renovations occurring in 2017, when Unit #1 received a kitchen and bathroom remodel including new cabinets, floors, and electrical upgrades totaling $16,000. Prior improvements include water damage repairs in 2011, bathroom and kitchen renovations in Unit #4, and historical structural enhancements such as foundation bolting and shear wall installation in 1989. The building has maintained good compliance with safety inspections, with routine housing inspections in 1998 and 2006 showing no apparent violations.

Recent activity at the property has primarily involved parking enforcement issues, with numerous complaints about driveway blocking between 2022 and 2025, resulting in several citations being issued. A pavement defect was reported and resolved in February 2024, which may have affected access to the property. The building's maintenance history shows attention to both interior upgrades and structural integrity, with records indicating completion of various plumbing and electrical improvements in conjunction with the renovation work. While the recent parking issues suggest access challenges for residents, the building's overall permit and inspection record demonstrates regular maintenance and upgrading of systems.

Risk rating

How 3239 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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
43th percentile

Out of 988 buildings in this neighborhood, 563 are predicted to be safer.

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.

Neighborhood location

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

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

12-Month severity forecast
No violation 29.2%
Moderate concern 13.0%
Severe concern 57.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
