Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Rent & eviction protection

Is 3589-3593 Mission 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 1923

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 1923
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 Syty Family Trust owns this two-story, three-unit multi-family residential building located at 3589-3593 Mission Street in Bernal Heights, which was constructed in 1923. The property has undergone several significant changes and faced multiple compliance issues over its history. Most notably, in 2010, the building received multiple violations for unauthorized alterations, including the conversion of a single-family dwelling into two separate units with an illegally constructed second-floor unit containing three bedrooms, a living room, a bathroom, and a food preparation area. These violations, documented in complaint #201062717, also revealed several safety concerns including inadequate ventilation for windowless bathrooms, unauthorized windows, unapproved wiring and plumbing, questionable fire-resistant materials, and missing smoke detectors. The violations were officially abated by October 15, 2010, following the removal of the unauthorized kitchen and related modifications at a documented cost of $8,000, along with corresponding electrical and plumbing modifications.

The building's maintenance history includes several significant infrastructure improvements, such as the conversion of overhead electrical service to underground lines in 2003 (at a cost of $200,000), reroofing work completed in 1996, and various interior renovations in the late 1980s and early 1990s, including kitchen and bathroom updates and partition removals. The property has experienced recurring issues with mold and mildew, as evidenced by two separate complaints in 2010, and has undergone various repairs to address interior surfaces, windows, lighting, and smoke detection systems. While the building has faced multiple challenges regarding code compliance and maintenance, recent history shows no active violations or ongoing complaints related to the building's core systems or habitability. The surrounding area has experienced typical urban maintenance issues as documented in 311 calls, primarily relating to street cleaning and pavement defects, which are not directly related to the building's condition.

Risk rating

How 3589-3593 Mission 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

Lower risk — safer than most nearby

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
19thpercentile

Out of 1276 buildings in this neighborhood, 1034 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
