Rent & eviction protection

Is 1814-1818 Mason 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 before 1979
Built 1911
2 or more units

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 1911
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 three-story, six-unit multi-family residential building at 1814-1818 Mason Street in North Beach, owned by Fredrick W. Lui and Emily Kwan, was constructed in 1911 and has undergone several significant improvements over the past decades. Most notably, in 2014-2015, the building underwent substantial renovations including a first-floor interior remodel featuring a kitchen upgrade, bathroom renovations, and the installation of a new gas furnace system, for which the total renovation cost was approximately $54,000. The building also received important electrical upgrades, including a 200-amp service upgrade in 2005, and there were some permitted plumbing modifications as well.

The property has a recorded history of building inspections and violations, with a significant cluster of issues documented in 2004-2005 that were all resolved by August 2005. These violations included fire safety concerns such as combustible storage, inadequate fire extinguishers, and egress obstructions, as well as building maintenance issues like painted walls, stair repairs, and handrail installation needs. There were also concerns about lead paint hazards, electrical wiring, and lighting deficiencies that were subsequently addressed. More recent history includes a routine safety inspection in 2015 and two significant complaints regarding unauthorized occupancy programs in 2021 and 2022, including cancellation notices related to Intermediate Length Occupancy (ILO) violations, suggesting potential issues with short-term rental compliance. The building's most recent permitted activity, filed in June 2022, pertains to the use of the property as an Intermediate Length Occupancy with existing legally recognized use and occupancy, though this permit's current status is listed as "Filed."

Risk rating

How 1814-1818 Mason 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
69thpercentile

Out of 362 buildings in this neighborhood, 112 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Neighborhood location

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