Rent & eviction protection

Is 648 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

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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 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 7-unit, 3-story multi-family residential building at 648 Waller St in Hayes Valley, owned by the Burger Karin Gst Trust, was constructed in 1900 and has undergone several significant modifications and repairs over the years. Most notably, a $58,000 soft-story retrofit was completed in 2015 to comply with seismic safety requirements, including strengthening of crawl space cripple walls and installation of new shear walls. The building has faced various maintenance and compliance issues, with the most recent violations in February 2023 related to fire safety systems, including fire escape ladder maintenance, fire extinguisher inspection tags, and gas utility shutoff requirements, though these violations were abated by March 17, 2023. A greenhouse constructed on the roof in 2008 without proper permits led to additional compliance actions, and while the building underwent rear stair repairs, siding and window replacements in 2009, and multiple electrical system upgrades in 2004, several historical complaints and violations remain on record.

Recent maintenance concerns include multiple parking enforcement calls (2022-2024) for blocking driveways, and a water leak issue reported in November 2024, though this was accepted by SFWD for inspection. The property has undergone routine inspections by Housing Inspection Services in 1996, 2002, and 2003, revealing various maintenance issues including a no-heat complaint in 2003 and unpermitted apartment renovations in 2002. The building's electrical system was upgraded in 2004 with the installation of seven meters and a 200-amp service. While the soft-story retrofit was successfully completed, the building has experienced recurring issues with fire safety compliance and maintenance concerns that suggest ongoing challenges with property upkeep.

Risk rating

How 648 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
