1110 Jackson St

Nob Hill, SF 94133 0182037 9 units · 3 fl · 1961

Nothing on record for this building in the last seven years, but our model still flags a rising risk of maintenance problems in the next 12 months. That forecast comes from the owner's wider portfolio and the surrounding area, not from this building's own record — treat it as a reason to ask questions, not as evidence of a problem. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

The bar and the rating point different ways because they measure different things: the bar counts DBI violations already on file, the rating forecasts the next 12 months.

Rent & eviction protection

Is 1110 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 1961

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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 1961
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 9-unit, 3-story apartment building at 1110 Jackson Street in Nob Hill, owned by Kg Bay Area Investors LLC, has undergone several significant maintenance and safety improvements since its 1961 construction. Most recently, the building received a complete reroofing in June 2022 ($18,000), and in late 2021 underwent kitchen rewiring with new recessed lighting installation. The property has a history of water-related issues, particularly in 2004-2005 when multiple complaints were filed regarding ceiling leaks in Apartment #8, which required repairs to both the roof and water-damaged interior surfaces. These problems recurred to some extent, with additional leak complaints in 2005 and 2002. The building has also faced several safety-related violations over the years, including a corroded fire escape cable (2001), problems with the central alarm system (2000), and multiple fire safety concerns such as uncharged fire extinguishers and egress obstructions.

The property underwent routine housing inspections in 2000, 2002, 2010, and 2017, with most issues being addressed and resolved promptly. A notable tenant buyout occurred in October 2021, involving two tenants and valued at $50,000. More recently, a sprinkler system inspection in May 2024 was conducted with no significant findings. The building's maintenance history shows regular attention to building systems, with multiple permits for electrical upgrades and safety improvements. The surrounding area has experienced various street-related issues as recorded in 311 calls, including reports of abandoned furniture and waste, though these are more related to the neighborhood environment than the building condition itself.

Risk rating

How 1110 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
17thpercentile

Out of 1125 buildings in this neighborhood, 934 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.
