Rent & eviction protection

Is 528-532 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 before 1979
Built 1900

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 1900
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 property at 528-532 Oak Street is a three-story, five-unit multi-family residential building constructed in 1900 and currently owned by Stefan Giustino 1998 Revocable Trust. The building has undergone significant improvements in recent years, with the most recent permits in 2024 showing work on rear exterior stairs ($30,000), and earlier in 2023 for foundation work ($12,000) and the installation of a new fire sprinkler system throughout the ground floor ($22,498). A major renovation of Unit #2 was completed in 2022, including kitchen remodeling, insulation, electrical upgrades, and new systems, while the building's electrical infrastructure received substantial upgrades in 2021-2023, including new sub-panels for all units and an underground fire service installation.

The building has had some maintenance and compliance issues in the past, notably a series of violations in 2018 related to building safety, including requirements for carbon monoxide alarms and structural concerns with wood stairs, though these were all abated by November 2018. A 2019 violation regarding soft-story compliance was resolved in March 2023. Recent complaints from October 2023 expressed concerns about unit habitability and code compliance, though this was marked as not active shortly thereafter. The property has also experienced some management and maintenance challenges, including complaints about insufficient heat in 2016, construction dust issues in 2011, and reports of hoarding in mid-2021. The building has received proper attention to its soft-story requirements, achieving completed work and receiving the appropriate Certificate of Final Completion (CFC).

Risk rating

How 528-532 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
18thpercentile

Out of 1027 buildings in this neighborhood, 842 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
