Rent & eviction protection

Is 1425-1427 Oak 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 1900

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 1900
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 two-unit residential building at 1425-1427 Oak Street in the Haight Ashbury neighborhood is a two-story flats and duplex structure owned by the Dietrich-yee Family Living Trust and was constructed in 1900. The property has undergone significant improvements in recent years, particularly in 2016, when major work was completed including a $60,000 garage remodel with half bath addition, second floor kitchen renovation, and hallway lighting upgrades, along with $18,860 reroofing work. Important safety upgrades were implemented in 2014 with voluntary strengthening work including partial foundation replacement and installation of new structural components costing $16,000. The building's systems have seen substantial modernization, with complete electrical rewiring and plumbing updates in 2016, including kitchen water recoppering and new bathroom facilities installation.

The property has received regular maintenance and upgrades over the years, including an underground service conversion to a 200A system in 2004, though some permits from the late 1980s related to foundation work expired without completion. Recent events around the building have primarily consisted of municipal service calls, including multiple reports of abandoned vehicles and encampment-related issues in the vicinity between 2023 and 2024. These external matters, while recorded, do not directly reflect on the building's condition or maintenance. A single fire incident was recorded, but was categorized as a false alarm with no civilian injuries reported. The building's most recent approved planning work includes window modification and interior improvements, along with the addition of a half bath in the garage area, suggesting ongoing commitment to property enhancement and maintenance.

Risk rating

How 1425-1427 Oak 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
76thpercentile

Out of 581 buildings in this neighborhood, 139 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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Building age

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