Rent & eviction protection

Is 3255 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.

Built before 1979
Built 1924
2 or more units

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 1924
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, 12-unit building at 3255 Laguna Street in San Francisco's Marina neighborhood, owned by Malvin & Connie Wong Fmly T Trust, has a century-long history dating back to 1924. The property has experienced several significant maintenance and safety issues in recent years, most notably three fire incidents and multiple building violations in 2022, including a documented "nuisance" designation under San Francisco Housing Code Section 1001-d related to scorched areas from a fire incident near the chestnut street elevation. A concerning safety incident occurred in January 2021 when roof tiles fell from the building's third story, landing dangerously close to a public bus stop. More recently, there has been an emerging pattern of sidewalk issues around the building, with multiple reports of collapsed sidewalks in 2026, culminating in an accepted request for repairs under permit #26EXC-01121. The building's service request record shows a total of 145 311 calls over the past seven years, though most are not detailed in the summary. While two DBI complaints from 2022 have been resolved, including one related to fire damage, there are still open service requests as of 2026, including concerns about human waste or urine on the property. The combination of fire incidents, rooftop safety concerns, and ongoing sidewalk issues suggests attention is needed to address various maintenance and safety aspects of this aging structure, though it's important to note that many historical violations have been marked as "not active."

Risk rating

How 3255 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
28th percentile

Out of 988 buildings in this neighborhood, 711 are predicted to be safer.
