Rent & eviction protection

Is 727-731 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 1900

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 727-731 Waller Street property is a three-story, 6-unit multi-family residential building located in Hayes Valley, constructed in 1900 and currently owned by the 1993 Kellerman Family Trust. The building has undergone several significant improvements in recent years, most notably completing a mandatory soft-story retrofit in 2019 at a cost of $35,000, bringing it into compliance with seismic safety requirements as a Tier 3 building. Other notable recent improvements include a gas line replacement in 2011, and the installation of low-frequency sounders in 2020. The building has a documented history of proper maintenance and upgrades, including a kitchen and bathroom remodel in 2012 that included extensive electrical work and plumbing updates.

The property has experienced some issues in the past, particularly in 2002 when multiple fire safety violations were recorded, including problems with combustible storage, fire extinguishers, dryer ventilation, and the central alarm system, though these violations were all abated by December 2002. While there have been three documented gas-related incidents (two gas leaks and one carbon monoxide detector activation with no CO detected) according to fire incident records, there were no civilian injuries reported in any of these incidents. The building has undergone routine housing inspections in 2002 and 2009, with no active violations currently on record. Recent external maintenance has included responses to various 311 calls regarding street conditions, though these are primarily related to sidewalk maintenance and public space issues rather than building-specific concerns. The most recent building-related complaint as of October 2024 involves a missing side sewer vent cover, which remains open.

Risk rating

How 727-731 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
85thpercentile

Out of 1027 buildings in this neighborhood, 154 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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Building age

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