Rent & eviction protection

Is 50-52 Bannan Pl 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.

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 1907
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-story multi-family residential building at 50-52 Bannan Place in Telegraph Hill, owned by 1453 Grant LLC, has undergone significant recent improvements and has a history of maintenance issues dating back to 2004. Most notably, in 2022-2023, substantial renovations were completed including a comprehensive kitchen and bathroom remodel valued at $99,000, replacement of all residential windows, installation of a heat pump mini-split system, and complete electrical wiring updates to replace knob-and-tube systems. These improvements were accompanied by some resident complaints about construction noise in early 2023. The building's maintenance history reveals several concerning issues, particularly during the mid-2000s, including multiple violations in 2004 related to security, fire safety, and building systems, which were generally resolved by July 2004. Previous problems included water intrusion and mold issues in 2005-2006, lead paint concerns in 2012, and dry rot repair at the rear of the structure in 2017. Recent inspections and permits suggest proactive maintenance and upgrading of building systems, though there remains a pattern of environmental cleanliness issues in the surrounding area based on 311 calls for 2023-2024. The most recent building violation record shows an active noise complaint in 2023, while all other historical violations have been marked as not active or resolved. The property underwent routine inspections in 1999, 2004, and 2006, which indicate periodic oversight of building conditions, though specific findings from these inspections are not detailed in the available records.

Risk rating

How 50-52 Bannan Pl'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

Out of 684 buildings in this neighborhood, 561 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.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Building age

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

12-Month severity forecast
No violation 46.6%
Moderate concern 24.7%
Severe concern 28.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
