Rent & eviction protection

Is 456 Green 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 1906

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 1906
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 5-unit residential building at 456 Green Street in Telegraph Hill, owned by Leon Wong Co Inc, is a 3-story multi-family structure built in 1906 that has undergone several significant improvements over the past decades. Most notably, the building completed mandatory seismic retrofitting in 2017 at a cost of $42,500, bringing it into compliance with current safety standards as a Tier 3 soft-story building with a Certificate of Final Completion issued. The property has maintained its infrastructure through various important upgrades, including a complete reroofing in 2000 ($7,400), and comprehensive gas line replacements in units 1, 2, and 3 in 2016.

The building's maintenance record shows regular upkeep, with several permits issued in recent years for street space usage in 2018-2019. Historical improvements include interior renovations from 1988 (kitchen and bathroom updates) and compliance work from 1982. While there have been routine housing inspections conducted in 2000, 2003, and 2006, the building has not had any active complaints since then. The property has experienced typical urban challenges as documented in 311 calls, primarily relating to exterior issues such as graffiti (2018, 2020), sidewalk cleaning (2021, 2016), and occasional parking concerns (2024). These external matters have generally been promptly addressed by the relevant city departments, indicating responsive management of such incidents.

Risk rating

How 456 Green 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
33rdpercentile

Out of 684 buildings in this neighborhood, 458 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.

Number of units

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

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Building size

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