Rent & eviction protection

Is 1300-1310 12Th 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.

Built before 1979
Built 1955

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 property at 1300-1310 12th Avenue is a two-story mixed-use building constructed in 1955, consisting of 10 residential units above a commercial space, currently owned by the Colabianchi Carol A Revoc Trust. The building has undergone several significant improvements over the past two decades, including a completed soft-story retrofit in 2018 (classified as Tier 4) that addressed seismic safety concerns in both the residential and commercial portions of the building. More recent commercial modifications include the conversion of a former salon into a limited restaurant cafe in 2021, which has included both plumbing and electrical upgrades.

The building has experienced some maintenance and compliance issues over its history, particularly in 2002 when violations were issued regarding lighting fixtures and back stairs, though these were all resolved by December 2002. There have been three notable building complaints in recent years: in 2021 regarding work beyond the scope of a permit (active as of the last known status), in 2019 concerning common area maintenance, and in 2022 regarding expired permits but this was promptly resolved. The property has also seen its share of plumbing and electrical upgrades, including a 2020 hot water flue replacement and common area rewiring related to the soft-story retrofit.

Risk rating

How 1300-1310 12Th 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
4thpercentile

Out of 1493 buildings in this neighborhood, 1433 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.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Neighborhood location

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