Rent & eviction protection

Is 1370 16Th Ave 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 1925

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.

Built 1925
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 4-unit, 2-story multi-family residential building at 1370 16th Ave in the Inner Sunset, owned by Seto Nora B Revocable Trust, has undergone several significant renovations and faced multiple maintenance issues since its construction in 1925. Most notably, Unit 1 received substantial renovations in 2021, including a kitchen and bathroom remodel with electrical upgrades including lighting, receptacles, and a 60-amp sub-panel installation, along with plumbing improvements. More recent maintenance work includes the replacement of the clay house trap and lateral, and furnace replacement with flue repair completed in October 2024.

The property has experienced recurring sewer issues, with the most recent complaint filed in September 2024 regarding sewage leaking from the garage, following a similar problem reported in 2020 that affected neighboring properties. There have also been recent concerns about unauthorized renovations in July 2024, involving hammering and removal of materials from Unit 4, and an unpermitted installation of a tankless water heater creating vibration issues. Historical records reveal a pattern of maintenance challenges, with multiple violations documented in 2001 related to electrical, fire safety, and security issues, all of which were abated by October 2001. The building has undergone routine inspections and several 311 calls related to plumbing issues, parking violations, and general maintenance, with the most recent plumbing-related incidents occurring in 2020, 2022, and 2023. While a fire complaint from 2017 was found to have no merit, the building's maintenance history shows a need for ongoing attention to plumbing systems and building upkeep.

Risk rating

How 1370 16Th Ave'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
45thpercentile

Out of 1493 buildings in this neighborhood, 821 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Neighborhood location
