Rent & eviction protection

Is 3909 Irving 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 1963
2 or more units
5 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.

15+ years since occupancy
Built 1963
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 3909 Irving Street in the Outer Sunset was constructed in 1963 and currently consists of four units. The property has undergone significant improvements and compliance upgrades in recent years, most notably the addition of an ADU (Accessory Dwelling Unit) on the first floor in 2019, which added two bedrooms, a living room, kitchen, and bathrooms at a cost of $80,000. Between 2020-2024, the building received substantial safety upgrades including a new fire alarm and sprinkler monitoring system ($13,934), a ground floor fire speaker system ($18,000), and a major electrical service upgrade to 400A completed in 2021. The building has maintained active compliance with fire safety requirements, as demonstrated by the 2020 fire system installations and the recent permit issued in October 2024 for siding improvements to convert wood siding to new stucco. A plumbing complaint was filed in June 2020 regarding improper venting and noisy piping installation during the ADU construction, though this complaint is now listed as not active.

The property has a history of addressing maintenance and safety concerns, including earlier renovation work in 2013 that encompassed unit upgrades in both Unit 1 and Unit 3 involving tile replacement and painting. Historical records show a cluster of violations in February 2002 related to fire safety equipment and maintenance issues, including fire extinguisher recharging and combustible storage, all of which were abated by April 2002. Earlier concerns from 1997 regarding electrical issues were also addressed promptly. The building's exterior and immediate surroundings have experienced typical urban maintenance issues as documented in 311 calls, including incidents of graffiti, sidewalk parking, and street cleaning needs, though these are not directly related to building conditions or safety. The property has consistently demonstrated responsiveness to maintenance and safety requirements, with most recent improvements focusing on modernizing safety systems and upgrading living spaces.

Risk rating

How 3909 Irving 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
55thpercentile

Out of 632 buildings in this neighborhood, 284 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
