Rent & eviction protection

Is 77-83 9Th 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 1912

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 1912
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 six-story, 62-unit apartment building at 77-83 9th Street, owned by Lem/ray Properties LLC, was constructed in 1912 and has undergone numerous modifications over the years, with significant recent activity in 2024 including T-Mobile antenna upgrades on the rooftop ($115,000) and electrical system improvements. The property has had recurring maintenance and safety issues in recent years, particularly in 2023-2024, with multiple fire safety violations including problems with sprinklers, standpipe systems, and alarm systems. There have been two open violations from late 2023 regarding sleeping area requirements at the building. Between 2020-2021, residents reported several concerning maintenance issues including lack of hot water, heating problems, and water damage near electrical outlets. A series of electrical and plumbing upgrades have been completed over the years, including water heater replacements and kitchen renovations, though some infrastructure challenges persist, as evidenced by recent work to replace breakers and improve battery systems.

The building's history includes a notable transitional period from 2017-2018 when a medical cannabis dispensary was established on-site, which has since been converted to retail use with no significant structural changes. Multiple roof modifications have been performed for telecommunications equipment, first by Sprint in 2014 and more recently by T-Mobile in 2023. Historical complaints filed against the building in 2016 documented issues with mold, electrical systems, and interior surfaces, which were subsequently addressed. The property has also undergone various infrastructure improvements including fire suppression system upgrades and elevator maintenance, though some recent fire safety violations suggest ongoing compliance challenges.

Risk rating

How 77-83 9Th 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
0thpercentile

Out of 430 buildings in this neighborhood, 430 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
