Inner Mission, SF 94110 6524041 2 units · 2 fl · 1979

Nothing on record for this building in the last seven years, but our model still flags a rising risk of maintenance problems in the next 12 months. That forecast comes from the owner's wider portfolio and the surrounding area, not from this building's own record — treat it as a reason to ask questions, not as evidence of a problem. 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 2985-2987 Folsom St rent-controlled?

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 1979
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
May be covered by AB 1482. The building is old enough for the statewide rent cap (5% + regional CPI, capped at 10% per year) and just-cause protection after 12 months of tenancy.

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 two-unit residential building at 2985-2987 Folsom Street in the Inner Mission, owned by Franklin Tieu, was constructed in 1979 as a two-story flats and duplex structure. The property has undergone several significant maintenance and improvement projects over the years, including a roof replacement in 2013 costing $6,700, electrical system upgrades with a 200-amp underground conversion in 2004, and siding repairs at the rear completed in 1992. However, the building experienced a notable cluster of maintenance issues in mid-2019, with multiple complaints filed between June and July of that year regarding inadequate heating, mold problems, plumbing issues including water pressure problems, interior surface deterioration, and the absence of required smoke and carbon monoxide detectors. These violations were officially abated by September 2019, though they indicated a period of significant tenant dissatisfaction.

The building has had consistent maintenance work performed over its lifetime, with the earliest records showing work completed in 1981 and a basement usage permit from 1983 (which expired). More recently, there has been an ongoing pattern of parking-related complaints in the vicinity of the property, with multiple citations issued between December 2023 and early 2025, though these are external to the building itself. There have also been several reports of garbage and debris issues on or near the property between 2023 and 2024, suggesting some ongoing challenges with exterior maintenance, though these are primarily street cleaning matters rather than direct building maintenance concerns. The most significant historical building-specific complaint dates back to 1994 regarding potential fire safety concerns about cooking in the garage, which was promptly resolved.

Risk rating

How 2985-2987 Folsom 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
18thpercentile

Out of 2380 buildings in this neighborhood, 1952 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
