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 1615-1617 Folsom 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 1907

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 1907
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 property at 1615-1617 Folsom Street is a two-unit, two-story multi-family residential building constructed in 1907, currently owned by the Ching Chih Young Revocable Trust. The building has undergone several significant maintenance and improvement projects over the years, with the most recent being dry rot repairs in the garage/basement area in 2018, costing $10,000. A reroofing project was completed in 2006 at a cost of $5,900, though records show multiple older reroofing permits from 1994, 1996, and 1984 that are listed as expired. The property has a relatively clean maintenance record, with no major violations or safety concerns documented in recent history.

The building's maintenance history shows regular upkeep, particularly regarding the roof, which has been addressed multiple times over the decades. In early 2025, there were several reports of graffiti on the building and surrounding areas, though most of these cases were either unable to be located or were resolved by city agencies. There have also been a few reports of abandoned items (including Christmas trees and a mattress) on the street near the property, all of which have been addressed by city services. The property underwent a 12 x 25 general advertisement wall sign project that was permitted and subsequently abated, though there are no records indicating this work was completed. While the building has experienced some recent issues with graffiti and street cleanliness in the surrounding area, these appear to be consistent with urban living challenges rather than specific building maintenance concerns.

Risk rating

How 1615-1617 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
49thpercentile

Out of 430 buildings in this neighborhood, 219 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.
