Rent & eviction protection

Is 106 Sagamore 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 1916
2 or more units

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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 1916
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

106 Sagamore Street is a multi-family residential building located in the Oceanview neighborhood, owned by Karl Tang Boune and Yuen Phon. This 1916 structure, categorized as a 4-unit Flat & Store, has undergone several significant improvements in recent years. Most notably, a complete reroofing of the front building was completed in February 2024 at a cost of $12,000. In 2019, the property received a major electrical upgrade, converting to a 200-amp service with four meters. The building underwent important administrative changes in late 2017, with permits issued to clarify its legal use and occupancy as a single-family dwelling with commercial space in the front, and a two-unit residential structure in the rear.

The property has maintained demonstrated investment in upkeep, with work in 2018 including staircase repairs and window replacements in the rear building. A series of 311 calls in 2024 primarily concerned vehicle-related issues, including multiple reports of abandoned vehicles that were ultimately determined to be false claims. The same period saw several reports of street cleaning needs and one instance of graffiti, all of which were resolved. A historical fire safety violation record from 2008 showed multiple issues requiring permits and extinguisher service, though these were properly closed upon compliance. The building's recent maintenance history suggests active management, particularly with the electrical and roofing improvements, while the 311 calls primarily relate to external street conditions rather than building-specific issues.

Risk rating

How 106 Sagamore 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
44thpercentile

Out of 79 buildings in this neighborhood, 44 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 location

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

Property class: apartment building

Apartment building — this property classification influences expected violation rates.

Building age

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