Rent & eviction protection

Is 400-402 Prentiss 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.

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 multi-family residential building at 400-402 Prentiss Street in Bernal Heights is a two-unit, two-story structure built in 1900, currently owned by Riechers Christina & Bale L. The property has undergone significant recent renovations, with major work occurring between 2019-2022 including bathroom and office additions, bedroom and kitchen relocations, and foundation replacement costing in excess of $300,000. During this period, numerous plumbing and electrical upgrades were completed, including the installation of a hydronic heating unit, solar panel system, and replacement of old knob and tube wiring. The building experienced several construction-related issues in 2019, including complaints about unauthorized third-floor work and construction dust entering units, though these complaints have since been marked as not active.

Most concerning are recent sewer-related incidents, with multiple sewage backup discharge reports from August 2024 (four separate incidents), suggesting potential plumbing system issues. The property has also had some infrastructure concerns noted in 2024, including an open pavement defect report and a tree maintenance issue affecting the building's window or structure. Historical records show earlier improvements including roof repairs, basement reinforcement, and porch renovations dating back to the 1990s and 2000s. The owners previously completed tenant buyouts at the property in December 2018 ($32,000 for 2 tenants) and October 2020 ($148,000 for 5 tenants), indicating significant turnover prior to the recent renovations. Compliance records show various permits for interior work and modifications, with specific attention paid to maintaining cumulative interior demolition within acceptable limits.

Risk rating

How 400-402 Prentiss 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
66thpercentile

Out of 1276 buildings in this neighborhood, 434 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
