Nob Hill, SF 94109 0185020 3 units · 2 fl · 1911

Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Rent & eviction protection

Is 1490-1494 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

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 three-unit multi-family residential building at 1490-1494 Jackson Street in Nob Hill, owned by Nga Ling Wong Jow Tr, was constructed in 1911 and underwent significant renovations between 2009 and 2012. The most substantial project occurred in 2009 when a fourth floor was added, along with an expanded porch area, rear stair enclosure, and a new efficiency unit behind the garage, during a major $500,000 renovation that also included updates to the foundation, mechanical, electrical, and plumbing systems. The building received comprehensive safety upgrades, including the installation of a fire sprinkler system with 71 heads (completed in 2011) and a manual fire alarm system with multiple safety features (completed in 2012). Subsequent modifications included kitchen relocations, window replacements, and closet changes on various floors, all completed under permits from 2012.

More recent history shows primarily external issues, with several 311 calls in 2020-2024 mostly related to illegal parking, with eight instances of reported violations resulting in citations. There have been few recent building-related complaints, with the most recent being a garbage and debris report in December 2024. The extensive renovation work completed between 2009-2012, including new furnaces, chimneys, electrical systems, and life-safety improvements, suggests the building received significant modernization and safety upgrades during that period, with all major permits showing as completed. The property is now fully transitioned to its updated configuration with no outstanding permits or significant building-related issues in recent years.

Risk rating

How 1490-1494 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

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
59thpercentile

Out of 1125 buildings in this neighborhood, 461 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
