Rent & eviction protection

Is 1100 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 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.

15+ years since occupancy
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 16-unit, 4-story multi-family residential building at 1100 Jackson Street in Nob Hill, built in 1909, has undergone significant improvements and faced various challenges over the years. Most notably, the building completed its mandatory fire safety upgrades in 2021 with the installation of a new fire alarm system including low-frequency horns, smoke detectors, and other safety features. A major soft-story retrofit was completed in 2016 with the installation of a Simpson moment frame over the garage door, demonstrating compliance with San Francisco earthquake safety requirements. The building has undergone substantial unit renovations, including comprehensive remodels of units 4, 9, 10, and 11 between 2003 and 2013, which included kitchen and bathroom upgrades, electrical rewiring, and plumbing improvements. The property has maintained active fire safety compliance, with regular inspections and corrections, though a 2019 violation related to sprinkler service was noted. Historical issues from 2002 highlighted various maintenance concerns that have since been addressed, including plumbing leaks, damaged surfaces, and pest problems, all of which were officially abated by May 2002.

Recent inspection and maintenance records show ongoing attention to building systems and safety features, including electrical upgrades such as the installation of 8 exit signs in 2018. The building has experienced typical urban incidents, including elevator rescues and kitchen-related emergencies, though none have resulted in civilian injuries. Current maintenance records indicate regular upkeep, with recent fire alarm system maintenance in 2023 showing continued attention to safety systems. The building's owners, 1100 Jackson Assoc LLC, have demonstrated commitment to addressing both immediate and long-term building safety and habitability requirements, as evidenced by the completion of major structural improvements and consistent response to inspection findings. The property's most recent activities primarily involve routine safety system maintenance and responses to normal building operations, with no current active violations or major outstanding issues.

Risk rating

How 1100 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.

Neighborhood percentile
10th percentile

Out of 1125 buildings in this neighborhood, 1012 are predicted to be safer.

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.

Number of units

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

Building size

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

Neighborhood location

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

12-Month severity forecast
No violation 10.3%
Moderate concern 30.9%
Severe concern 58.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
