Rent & eviction protection

Is 810 Lyon 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.

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 1966
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 3-unit, 3-story multi-family residential building at 810 Lyon St, built in 1966 and currently owned by 810 Lyon St Partners LLC, has undergone significant recent maintenance and improvements. Most notably, in early 2024, the building received attention to its exterior with balcony repairs and partial replacement of siding on both sides of the building. Between 2020 and 2021, substantial interior upgrades were completed, including comprehensive kitchen and bathroom remodels in multiple units (totaling $80,000), electrical system improvements with sub-panel upgrades and new lighting installations, and plumbing updates including bathtub and sink replacements. Several building complaints from 2021 regarding unpermitted construction work and safety concerns were investigated, but no violations were ultimately sustained. The building's maintenance record shows regular upkeep, including the 2016 installation of modern amenities in Unit 3 and the 2023 modification of gas lines and water heater.

Historical records from 2001-2005 indicate past fire safety concerns, including egress obstructions and combustible storage issues, though all these violations were abated by October 2001. More recent concerns have primarily centered around parking issues, with numerous citations issued in 2024 for sidewalk parking violations and blocked driveways near the property. The building has undergone various permitted improvements over the years, including rear stair replacements, siding repairs, and balcony modifications. While there were some historical maintenance issues in 2012 related to mold and water damage, these were addressed, and recent records indicate active management attention to building upkeep and repairs.

Risk rating

How 810 Lyon 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

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
