Rent & eviction protection

Is 426-428 Waller 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 1900
2 or more units

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 1900
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 426-428 Waller Street in Hayes Valley is a two-story flats and duplex structure built in 1900, currently owned by Dana Ivan. The property has undergone several significant renovations and faced notable challenges over the years. A major incident occurred in 2011 when the building sustained fire damage, particularly affecting the west elevation wall and upper floor kitchen ceiling, which required subsequent abatement and repairs costing $25,000. In 2012-2013, the building underwent substantial improvements including the replacement of interior stairs with a new third-story deck and spiral stairs, foundation work for the lower deck, and electrical upgrades including kitchen rewiring and a new tankless water heater installation. The building's infrastructure has seen significant upgrades since 2005, including a 200-amp electrical service upgrade and furnace installation. However, there have been multiple building violations, including expired permits for interior wall removal in 2007 and fire-related violations in 2011 that are still listed as active.

Recent history shows ongoing maintenance issues in the vicinity, with multiple 311 calls in 2024 regarding garbage, parking violations, and sidewalk conditions, though most of these were resolved promptly. A collapsed sidewalk complaint from September 2023 is currently open and accepted. Planning records indicate approved projects for side and rear yard alterations, including exterior secondary rear egress stairs. The building's recent activity suggests regular maintenance and improvements, though the outstanding building violations and the age of the structure warrant attention to ongoing maintenance requirements. The most recent permits and improvements have generally focused on safety upgrades and infrastructure improvements, suggesting proactive maintenance by the current ownership.

Risk rating

How 426-428 Waller 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
82ndpercentile

Out of 1027 buildings in this neighborhood, 185 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.

DBI complaint rate, owner's portfolio

Per-building complaint rate across the owner's portfolio.
