Rent & eviction protection

Is 1200-1208 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 1909
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 1909
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 26-unit, 4-story building at 1200-1208 Mason St in Nob Hill, constructed in 1909, is currently owned by Chinese Community Housing C. The property has experienced significant activity in recent years, particularly regarding unpermitted construction work, with multiple resident complaints filed between August 2025 and March 2026 concerning loud demolition work and construction activities, some of which were documented as potentially dangerous and disruptive to residents' quality of life. These construction issues coincided with several building permits for interior work, including tenant improvements for a new coffee shop in October 2025 and storefront window and door replacements in February 2026. The building's permit records show substantial investment in improvements, with construction costs totaling over $7.9 million in the past seven years, including notable projects such as T-mobile equipment upgrades in 2024 and the installation of a handicap stairlift for a veteran in June 2024.

The property has a documented history of 5 fire incidents and 312 service requests over the past seven years, including recent concerns about overgrown trees and sidewalk parking issues. A notable violation was recorded in June 2022 regarding an unpermitted boiler operation, though this violation is currently listed as not active. The building has undergone various improvements and maintenance work, as evidenced by the multiple permits issued in recent years. The most recent 311 service requests indicate ongoing property management attention to maintenance and public space issues around the building, with cases related to encampments, garbage, and tree maintenance being opened throughout 2026.

Risk rating

How 1200-1208 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
22ndpercentile

Out of 1125 buildings in this neighborhood, 878 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.

Building size

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

Number of units

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

Neighborhood location

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