Rent & eviction protection

Is 15-17 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 before 1979
Built 1949
2 or more units

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

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 two-story multi-family residential building at 15-17 Mayfair Drive, owned by Frank L Kong, was constructed in 1949 and contains three units. The building's maintenance record shows a significant roofing project undertaken in 2006, costing $6,850, though this is now nearly two decades old. A potentially concerning issue arose in July 2021 when a complaint was filed regarding paint scraping and lead paint concerns, though this complaint is currently listed as "Not Active" with Housing Inspection Services.

The property has experienced various issues in recent years, with the most notable incidents being a flooding/sewer issue reported in February 2024 and a blocked driveway complaint in November 2024. A pattern of street maintenance and cleanliness concerns is evident, with multiple reports of general cleaning needs, loose garbage, and debris between 2022 and 2024, all of which have been resolved. Two instances of graffiti were reported in late 2022 and October 2023; however, the latter case was determined to involve a building on Laurel Street rather than the reported location. The only plumbing-related incident on record, a water leak reported in 2017, was investigated by the PUC Water department and found to be invalid, with no leak detected in the area.

Risk rating

How 15-17 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
24thpercentile

Out of 272 buildings in this neighborhood, 207 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
