Rent & eviction protection

Is 741-743 Castro 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 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.

15+ years since occupancy
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 three-story multi-family residential building at 741-743 Castro Street, owned by 741 Castro LLC, was constructed in 1906 and contains four units. The property has undergone several significant structural and maintenance improvements over the years, with notable work performed between 2008-2012 including foundation and structural work along the west property line, garage level strengthening, and a comprehensive $25,000 reroofing project in 2012. The building experienced multiple compliance issues in the mid-2000s, with several violations related to unauthorized renovation work, including a 2007 incident involving unpermitted bathroom and kitchen demolition, which resulted in multiple enforcement actions and corrections between 2007-2012. The property has maintained its electrical systems through various upgrades, including a 200-amp service upgrade in 2010, and has addressed plumbing needs such as shower pan installation and flue venting systems.

Recent maintenance records from 2024 show some ongoing infrastructure challenges, including a sewage backup issue and a pavement defect, though these were resolved through appropriate channels. The building's history includes several routine inspections and permit renewals, with particular attention paid to structural stability and safety systems. Planning records indicate approved variance requests for rear yard modifications, specifically for reconstructing and enlarging a sunroom at the attic level. While the property has faced various compliance challenges in the past, particularly during the mid-2000s, recent records suggest improved maintenance practices and responsiveness to building codes and regulations. The most recent building age-related complaints have been primarily for parking and sidewalk issues rather than structural or safety concerns.

Risk rating

How 741-743 Castro 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.
