Rent & eviction protection

Is 50 Laguna 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.

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
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 63-unit, 6-story apartment building at 50 Laguna Street, built in 1928 and currently owned by 16-50 Laguna I2 LLC, has undergone significant interior renovation work in recent years, with multiple units receiving kitchen and bathroom reconfigurations, including washer/dryer installations. Between 2020 and 2022, the building completed at least eight major renovation projects focusing on updating kitchens, bathrooms, and adding laundry facilities, with costs ranging from $5,000 to $55,000 per unit. A notable recent issue is an open violation dated November 26, 2023, regarding sleeping area requirements that requires permit processing. Historical records from 2012 through 2013 show several violations primarily related to building identification, a cell site installation without proper permits, and issues with a basement garbage room constructed without the required materials and ventilation. There were also concerns in 2017 about an expired elevator permit, multiple water shutoffs, and plumbing work, though many of these issues were subsequently addressed. Recent months (October-December 2024) have seen multiple reports of garbage and debris on the property, though most were resolved promptly. The building has had several fire-related incidents, mostly involving system malfunctions or medical assists, with no civilian injuries reported. A landmark designation proposal and ADU addition application were previously filed but have since been marked as cancelled/closed.

Risk rating

How 50 Laguna 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
