Rent & eviction protection

Is 1434-1436 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.

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-unit residential building at 1434-1436 18th Avenue in San Francisco's Inner Sunset neighborhood is a two-story flats and duplex structure built in 1925, currently owned by the Folk Carl Wilhelm Living Trust. The property has undergone significant improvements in recent years, with major renovation work completed in September 2021 including kitchen and bathroom remodels in both units, electrical system upgrades including a full building rewire and new subpanels, and associated plumbing work, totaling approximately $98,500 in investments. More recently, in May 2022, the building underwent additional work to comply with physical inspection report #CCC-8525, which included plumbing and electrical improvements, costing $3,000.

The building's maintenance history shows attention to structural upkeep, including a complete reroofing project in September 2021 involving installation of new modified bitumen roofing at a cost of $11,500. While there was one significant incident reported in April 2022 involving a sewage backup that was promptly resolved by PUC Sewer Operations, this appears to be the only recent infrastructure-related issue. The building underwent a condo conversion application process in 2021, which was approved and closed under the DPW referral for 2 units. Prior to the major renovations in 2021, there were multiple reports of abandoned vehicles in the vicinity between February and July 2015, though these incidents were unrelated to the building itself and were resolved with the vehicles being gone upon inspection.

Risk rating

How 1434-1436 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
95thpercentile

Out of 1493 buildings in this neighborhood, 75 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.

Notices of Violation, owner's portfolio

DBI NOVs across all buildings this owner is registered on — a signal of systemic maintenance issues across the portfolio.

Building age

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