Rent & eviction protection

Is 78 Mars 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 1906

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 1906
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 78 Mars Street in Corona Heights is a two-unit, two-story multi-family residential building constructed in 1906, currently owned by the Stinson Weiss Family Living Trust. Over the past decades, the building has undergone several significant renovations and improvements, with the most recent major work occurring between 2020-2021, including a third-story interior remodel with kitchen and bathroom updates ($50,000), sewer lateral replacement, and associated plumbing and electrical work. The building has seen consistent maintenance and upgrades, including multiple window replacements (most recently in 2018 with Marvin wood and Milgard fiberglass windows), kitchen and bathroom renovations (2003 and 2020), and infrastructure improvements such as a 200-amp electrical service upgrade and the installation of 12 rooftop solar panels in 2012.

Historical records show some construction-related issues in 2001 regarding a retaining wall and deck work that prompted a building complaint, though this violation was abated in early 2002. The property has maintained active compliance with permits and generally demonstrates regular upkeep. Recent 311 calls (2022-2024) have primarily related to external matters such as parking issues, sidewalk graffiti, and street maintenance, rather than building-specific concerns. The most recent building permits and improvements suggest ongoing investment in the property's maintenance and modernization, particularly focusing on interior spaces and energy efficiency features.

Risk rating

How 78 Mars 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
92ndpercentile

Out of 348 buildings in this neighborhood, 28 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 age

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

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.
