Rent & eviction protection

Is 181-185 Saturn 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.

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 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 three-unit, two-story multi-family residential building at 181-185 Saturn Street in Corona Heights, owned by Arthur S Barbour 2016 Lvg T, was constructed in 1907 and has undergone several significant maintenance and repair projects over the years. The most recent major work was completed in 2021 with the replacement of the house trap on the sidewalk, demonstrating ongoing infrastructure maintenance. Historical records show attention to structural safety and compliance, with notable events including a stair repair in 2002 following a housing inspection violation, bathroom remodeling in 1990, and multiple window replacements, the latest occurring in 2010. The building has had several maintenance tasks completed successfully, including reroofing in 2003 and various compliance-related repairs in the early 1990s.

Recent activity around the property has primarily involved exterior maintenance matters, with multiple 311 calls in 2023 regarding waste management issues, particularly concerning toters being left out continuously. There have also been a few reports of street-related concerns such as graffiti (most recently in 2024) and temporary sidewalk blockages. While these external issues are being addressed by city services, they primarily relate to street management rather than direct building concerns. The property's documented history shows regular maintenance and prompt attention to violations when they occurred, with no active building violations or serious safety concerns currently on record.

Risk rating

How 181-185 Saturn 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
33rdpercentile

Out of 348 buildings in this neighborhood, 233 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
