Rent & eviction protection

Is 1439-1441 Oak 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 1909

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.

Built 1909
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 1439-1441 Oak Street property is a two-story, four-unit multi-family residential building located in the Haight Ashbury neighborhood, built in 1909 and currently owned by Linh Viet Nguyen. The building has undergone several significant renovations and repairs in recent years, including a major 2021 remodel costing $727,876 that involved substantial updates to multiple units, a voluntary seismic retrofit in 2022, and upcoming roof replacement work with an estimated cost of $27,000 scheduled for late 2024. However, the property has faced recurring maintenance and safety issues, particularly regarding water damage and structural concerns. A notable problem was reported in July 2023 involving water intrusion from a shower causing damage to the garage ceiling, which may have affected the building's structural integrity. Multiple active violations from 2018 remain unresolved, including issues with floor coverings, walkways, fire safety, heating systems, and interior surfaces, with some violations being referred for legal action. Other concerns include heating system problems in early 2023, unauthorized plumbing work in 2019, and multiple reports of water damage and mold issues between 2018-2019. The building has received permits for various infrastructure improvements, including a storm drain replacement (2019), furnace replacement (2023), and electrical upgrades.

Recent developments include tenant buyouts in late 2023 (two tenants) and early 2024 (one tenant) for $100,000 each, suggesting potential plans for further building modifications or redevelopment. Planning records indicate a proposal to reinstate a fourth dwelling unit and install new fire-rated windows, with previous approvals for significant horizontal additions and ADU construction, though some of these plans were withdrawn. The building has a documented history of maintenance issues requiring attention, with particular attention needed to address the outstanding violations and recurring water-related problems.

Risk rating

How 1439-1441 Oak 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
