Rent & eviction protection

Is 2050-2056 Chestnut 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 1927
2 or more units

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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.

Built 1927
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 15-unit multi-family residential building at 2050-2056 Chestnut Street, owned by HP Mallorca LLC, has undergone significant improvements and modifications since 2021, demonstrating a commitment to modernization and safety upgrades. Most notably, in 2023-2024, three new ADU units were successfully added to the ground floor, with comprehensive updates including new fire sprinklers, heat pumps, and a complete electrical rewiring of all three units. The building has received substantial fire safety upgrades, including a $34,560 fire alarm system upgrade in July 2023 to meet San Francisco Fire Code requirements, followed by additional fire alarm system improvements continuing into 2024. Other major improvements include the replacement of failed concrete slabs in 2021, installation of new storefront and ADA-compliant features in 2022, and the window replacement project that legalized 78 aluminum-clad wood double-hung windows on the building's street-facing facades.

The building has experienced several inspection and violation events related to fire safety systems, though most have been promptly resolved. Recent fire safety violations were mostly related to extinguisher maintenance and alarm systems, with the last major fire violation recorded in 2019 showing issues with building owner contact posting requirements, exit pathways, and sprinkler clearance. The property completed its soft-story retrofit requirements as a Tier 4 building. Additional work has included comprehensive plumbing updates such as re-piping of the entire building (2021), various sewer and drainage improvements, and multiple electrical system upgrades. Recent tenant feedback has involved reports of encampments and sidewalk debris around the property, as noted in 311 calls, though these are external to the building itself. The most recent tenant buyout was recorded in January 2022, involving one tenant and a payment of $150,000.

Risk rating

How 2050-2056 Chestnut 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
11thpercentile

Out of 988 buildings in this neighborhood, 879 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
