Rent & eviction protection

Is 15-17 Nantucket Ave 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.

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.

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-unit residential building at 15-17 Nantucket Avenue in Mission Terrace, owned by Lee Kwok-wing, has undergone several significant changes since its construction in 1961. In 2005, substantial modifications were made to the property, including the addition of a bedroom, storage room, full bathroom, and family room on the ground floor, along with a comprehensive electrical system upgrade to 200-amp service with multiple meters, panels, and new wiring installations, with these improvements totaling approximately $56,000. The building's maintenance record shows earlier care with a reroofing project completed in 1991.

The property has experienced numerous service calls and incidents in recent months, with the most notable being a sewage backup discharge from a side sewer vent in October 2024. There has been a concerning pattern of parking violations in the vicinity, with eight reported incidents between August and November 2024, though many could not be validated or resulted in no enforcement action. Several environmental issues have been reported, including two instances of garbage and debris on public property in late 2024, one of which involved accident debris. The building has also faced some structural challenges, as evidenced by a property damage report related to tree maintenance in September 2024. While these incidents primarily involve the surrounding area rather than the building itself, they may impact resident quality of life. It's worth noting that there was a tenant buyout at the owner's other property (30 Paulding Street) in 2020, though this is unrelated to the current building.

Risk rating

How 15-17 Nantucket Ave'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
91stpercentile

Out of 149 buildings in this neighborhood, 13 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.
