Rent & eviction protection

Is 302-308 31St 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.

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 1921
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-story, four-unit multi-family residential building at 302-308 31st Avenue in the Central Richmond neighborhood, owned by Gary M. Maganaris and built in 1921, has experienced several significant maintenance and safety-related issues over its history. Most recently, in 2017, the building underwent substantial voluntary strengthening work and retaining wall replacement at a cost of $60,000. Between 2005 and 2016, multiple serious concerns emerged, including substantial structural issues with rear stairs (2009), plumbing and sanitary problems including non-functional toilets (2005), and various fire safety violations. The 2001-2005 period saw multiple fire safety violations requiring remediation, including problems with combustible storage, fire proofing, and emergency lighting systems, all of which were eventually abated. The building has also experienced some recent infrastructure issues, with a sewage backup reported in January 2024 representing the most current maintenance concern.

Recent municipal service calls around the property (2023-2024) have primarily involved external issues such as parking violations, street cleaning needs, and some tree maintenance concerns, rather than internal building problems. A 2005 housing inspection noted several maintenance issues including a caving ceiling and insulation concerns, though during this period, there were also documented efforts to improve the building's safety systems, including the installation of emergency exit lighting and electrical improvements. While the building has had its share of problems over the years, particularly during the early to mid-2000s, many of these issues were addressed through subsequent repairs and improvements, with no active violations currently on record. The only documented fire-related incident was a false alarm, with no civilian injuries reported.

Risk rating

How 302-308 31St 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
26thpercentile

Out of 2250 buildings in this neighborhood, 1665 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.

Number of units

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

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.
