Rent & eviction protection

Is 3720 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 1931
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 12-unit, 3-story multi-family residential building at 3720 Fillmore Street, owned by Del-camp Investments Inc, has undergone significant upgrading over the past several years, particularly in its life safety systems. Most notably, in 2023, the building received a comprehensive fire alarm system upgrade (cost: $36,741) to comply with San Francisco Fire Department requirements, followed by an as-built modification in September 2023 that relocated various alarm components to centralize safety equipment near the main entrance. This upgrade included the installation of low-frequency sounders in sleeping areas to meet current safety standards. The building has seen substantial unit improvements, with multiple apartments receiving modernizations between 2014-2021, including complete kitchen and bathroom remodels in Units 102, 203, and 301, along with electrical rewiring upgrades and the addition of new appliances and fixtures. A significant voluntary strengthening project was completed in 2015 (cost: $50,000).

The property's maintenance history shows regular attention to building systems and infrastructure, with multiple plumbing and electrical upgrades completed in conjunction with unit renovations. Recent exterior and surrounding area management includes resolutions to various urban maintenance issues such as tree management (with multiple reports in 2021-2022) and sidewalk cleaning. The building has experienced several fire alarm system complaints/notifications over the years, primarily in 2008 and 2011, all of which were resolved promptly, with the most recent incident in June 2023 being corrected within a week. The property's violation history is minimal, with only one fire safety-related violation recorded in 2006 that was promptly addressed within two months. Recent 311 calls (2022-2024) primarily relate to external issues such as parking concerns and tree maintenance, rather than building-specific problems. The property's systematic approach to unit improvements and life safety system upgrades suggests ongoing commitment to maintaining and improving resident safety and comfort.

Risk rating

How 3720 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

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
28thpercentile

Out of 988 buildings in this neighborhood, 711 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.

Building size

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

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.
