Rent & eviction protection

Is 517-523 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 three-unit, two-story Victorian building at 517-523 Laguna Street in Hayes Valley, owned by the Young Family Trust, has experienced several notable incidents over the past few years. Built in 1890, this property has been the subject of 87 service requests through the city's 311 system in the last seven years, with a significant cluster of reports occurring in 2026. Most recently, there have been multiple service requests in June 2026 regarding sidewalk structures, with at least one case involving graffiti that required cleaning by the SES Graffiti Crew. There have also been recurring issues with garbage and debris, including reported instances of bagged garbage and discarded needles - though the needle complaint was noted as "not offensive" and required no work.

The building's safety record shows two documented fire incidents: a minor outside rubbish fire in July 2025, and an electrical wiring or equipment problem in April 2023, neither of which resulted in civilian injuries or fatalities. The property's 311 service request history reveals persistent challenges with debris management in the immediate vicinity, particularly in 2026, though many of these issues have been officially resolved. While the building's age and historical status as a Victorian structure may present some unique preservation considerations, the available data primarily highlights ongoing maintenance and cleanliness challenges in the surrounding area rather than structural or safety concerns with the building itself.

Risk rating

How 517-523 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.
