Rent & eviction protection

Is 91-97 Mayfair Dr 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 1949

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 1949
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 91-97 Mayfair Drive is a two-story, 4-unit multi-family residential building constructed in 1949, currently owned by Patrick J & Breda B Phillip. The building has undergone several significant improvements in recent years, including the replacement of six retrofit windows on the side facade in 2022 ($3,500) and remediation of dry rot through siding replacement in 2019 ($26,000). The building's mechanical systems have received attention with multiple furnace replacements in 2020 and 2021, and an electrical upgrade to a new 400-amp main service panel was completed in 2017, indicating efforts to maintain and modernize building systems. A heating complaint was recorded in January 2020, though this issue does not appear to have persisted.

The property has maintained regular building inspections and historically had routine inspections in 1999, 2004, and 2008, with a construction-related complaint in 2019 regarding work at 93-97 Mayfair Drive without permits. The most recent significant building-related activity is a "Rebuild Letter" application for the property has been processed, indicating potential future improvements. While recent 311 calls (September-October 2024) show multiple reports of encampments, garbage, and debris in the vicinity of the property, these external issues are related to street conditions rather than directly affecting the building itself. The building's permit history shows consistent attention to maintenance and compliance with building codes, with no current active violations or complaints.

Risk rating

How 91-97 Mayfair Dr'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
22ndpercentile
