Rent & eviction protection

Is 1230 Jackson 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 1911
2 or more units
6 units
Property type
Multi-Family Residential

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 1911
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 6-unit, 3-story multi-family residential building at 1230 Jackson Street in Nob Hill, constructed in 1911, has undergone significant improvements and maintenance over the past several years, with particular attention to safety systems and unit modernization. Most notably, in 2023, the building completed a mandatory fire alarm system upgrade to comply with SFFC requirements, installing wireless low-frequency sounders in sleeping areas and replacing existing devices in common areas at a cost of $43,766. The building has successfully completed its soft-story retrofit program requirements, which were initially triggered by violations between 2014-2021, with final completion and CFC issuance recorded as "Work Complete." Recent unit improvements include comprehensive renovations of multiple units (2, 3, 4, and 5) between 2016-2020, which involved kitchen and bathroom rehabilitations, washer/dryer installations, and various infrastructure upgrades including new electrical systems and retaining wall improvements.

The property has maintained active compliance with building codes, though it experienced some issues related to the soft-story retrofit timeline between 2014-2021, resulting in violation notices and monthly monitoring fees. Recent complaints from 2024 regarding netting blocking light and concerns about smoking in stairwells are currently under review, and there have been several 311 calls in 2024 related to sidewalk conditions and parking issues. Historical violations from the early 2000s concerning fire safety and storage have been resolved. The building's management has demonstrated responsiveness to maintenance needs, as evidenced by numerous completed permits for building improvements and safety upgrades, including substantial electrical work, plumbing updates, and general building maintenance. The most recent violation-related incidents have been addressed promptly, with most cases being marked as "Closed" or "Not Active."

Risk rating

How 1230 Jackson 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.
