Rent & eviction protection

Is 725-727 Webster 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 property at 725-727 Webster Street is a two-unit, two-story multi-family residential building located in Alamo Square, constructed in 1900 and currently owned by Abraham Mertens and Ivory Mad. The building has undergone significant renovations since 2017, including the installation of new HVAC systems, electrical upgrades to 400 amps with three meters, and a comprehensive bathroom remodel at unit 725. Structural improvements included foundation reinforcement in 2017 and the addition of a laundry closet on the second floor. The most recent major improvement was the installation of a washer/dryer in 2018, completed with associated plumbing and electrical work.

The building's history shows attention to maintenance and safety, though there are records of past issues. In 1996, there was a notable housing complaint about insufficient heat, door problems, and security concerns that were resolved within six months. A significant building fire occurred in 1999, and there was a rear stair and deck replacement in 1996, though both records are marked as expired. More recently, from late 2023 to present, there have been numerous 311 calls regarding garbage and debris on the property, particularly during autumn 2024, some of which required multiple follow-up visits from city officials. Additionally, there were housekeeping concerns noted during a recent construction project in late 2024 that required intervention from site supervision. These maintenance and cleanliness issues, while not directly related to building safety, may impact resident comfort and convenience.

Risk rating

How 725-727 Webster 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 305 buildings in this neighborhood, 46 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
