Rent & eviction protection

Is 135 18Th 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 1916
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 multi-family residential building at 135 18th Avenue, owned by the Low Gene K & Hannah S Trust, has a documented history spanning over two decades, with the most recent significant event being a comprehensive re-roofing project completed in October 2024 costing $30,000. The property experienced a notable fire incident in October 2021 that required repairs to two floor joints and subfloor work in Unit A, along with subsequent upgrades to the unit's systems including a new furnace installation, gas line addition, and electrical subpanel upgrade. The building's electrical infrastructure has seen improvements over the years, with a major upgrade from 100 to 200 amp service completed in 2005.

Of particular concern is the recent pattern of sewage-related issues, with multiple incidents reported through 311 calls in late 2024, suggesting ongoing plumbing system challenges. The property's maintenance history includes various works such as street space usage (2020), and a complaint in 2001 regarding unpermitted remodeling was filed and subsequently abated. The building's exterior envelope has required attention over time, as demonstrated by the recent re-roofing work, which replaced existing materials in-kind. The property has experienced some structural and accessibility issues, including a 2024 report of a difficult-to-open restroom door following renovations, though this was subsequently addressed according to records.

Risk rating

How 135 18Th 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
40thpercentile

Out of 660 buildings in this neighborhood, 396 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.

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.

Building age

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