Rent & eviction protection

Is 3650 Fillmore 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 1933
2 or more units
18 units
Property type
Multi-Family Residential
Zoning

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 1933
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 3650 Fillmore Street in the Marina district was built in 1933 and is currently owned by 3650 Fillmore Street LLC. The property has undergone several significant improvements in recent years, with the most notable being a major fire alarm system upgrade completed in October 2023 costing $33,600 to comply with current fire code requirements, and a separate fire alarm system modification in June 2023 that included upgrading the fire panel and installing low-frequency sounders in sleeping areas. Other substantial improvements include three recent kitchen remodels (2023, 2020, and 2019) in different units involving cabinet and countertop replacements, electrical upgrades, and appliance installation, along with a complete reroofing project in December 2022 costing $78,000 and structural strengthening of bay windows in 2015 costing $10,000.

The building has experienced several fire safety-related incidents over the years, including three instances of elevator rescues and multiple false alarms or system malfunctions, though no civilian injuries have been reported from these events. The property had several building violations in 2002 related to fire safety and heating system issues, including problems with egress obstructions, fire escape maintenance, and heating equipment, though all these violations were abated by June 2002. Recent 311 calls (from 2024) have primarily related to street maintenance and shared spaces issues outside the building rather than internal problems. The building's management has consistently addressed necessary repairs and upgrades, as evidenced by the completion of multiple permits and violations over the years.

Risk rating

How 3650 Fillmore 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

Out of 988 buildings in this neighborhood, 929 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.

Building size

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

Property class: multi-family flat

2–4 unit flats (class F) are a common SF building type with their own maintenance and complaint patterns.

12-Month severity forecast
No violation 30.8%
Moderate concern 23.7%
Severe concern 45.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
