Rent & eviction protection

Is 1401 Jones 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 1910

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.

Annual rent increase cap

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

1401 Jones Street is a four-story, 36-unit multi-family residential building located in San Francisco's Nob Hill neighborhood, owned by Lsl Properties B14 De Llc and constructed in 1910. The building has undergone significant renovations in recent years, with multiple apartment unit improvements documented between 2019 and 2024. Most recently, unit 409 received a comprehensive renovation in May 2024, including kitchen updates, new appliances, lighting, and fire safety improvements. The building is currently under work to install new wireless low-frequency sounders in sleeping areas to comply with San Francisco Fire Code requirements, with a permit issued in November 2023.

The property has experienced several notable issues related to building safety systems and fire compliance in recent years. Three violations were issued in March 2024 regarding the alarm system maintenance, UL certification, and sleeping area requirements, with an additional sleeping area violation pending as of May 2024. Historical records show a pattern of kitchen and bathroom renovations across multiple units (202, 301, 310, and 405) between 2019 and 2021, along with significant infrastructure improvements including the installation of tankless water heaters and backflow preventer replacement in 2019. The building had a serious incident in 2015 involving unauthorized demolition work in units 204, 303, and 308, which was investigated for potential conversion to short-term rentals. Previous violations from 2000-2009 included issues with fire escapes, which were subsequently abated, and there was a notable boiler failure and heating system complaint in 2013. While the building has maintained active compliance with most recent safety requirements, the recurring nature of some fire system violations (with three separate fire code violations in 2024 alone) suggests ongoing challenges with building systems maintenance and compliance.

Risk rating

How 1401 Jones 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
5thpercentile

Out of 1125 buildings in this neighborhood, 1069 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.

DBI complaint rate, owner's portfolio

Per-building complaint rate across the owner's portfolio.
