Rent & eviction protection

Is 1504-1506 24Th 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 1946
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.

15+ years since occupancy
Built 1946
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 1504-1506 24th Avenue property, a two-unit, two-story multi-family residential building located in the Central Sunset neighborhood, has undergone several significant renovations over recent years. Most notably, in August 2023, extensive kitchen and bathroom remodeling work was completed across both units, with associated electrical and plumbing updates totaling over $100,000. This work included the installation of new appliances, fixtures, and extensive electrical systems upgrades. As of October 2023, the building is undergoing roofing work, with permits issued for both reroofing and repairs around roof penetrations, totaling approximately $17,500.

The building has a documented history of maintenance and improvements dating back to the 1990s, including previous roof work in 1997, bathroom remodeling in 2013 (which expired and was subsequently renewed in 2023), and structural improvements to the garage walls in 1992. Recent 311 calls from 2022-2024 have primarily concerned external issues such as tree maintenance, sidewalk defects, and parking violations, though these do not directly impact building conditions. Of particular note are two open cases from 2022 related to an overgrown tree and sidewalk defect, as well as multiple recent complaints about driveway blocking in 2024. The property's maintenance record shows regular upkeep, with repairs and improvements being made as needed, though some permits have required renewal or re-issuance over time.

Risk rating

How 1504-1506 24Th 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
85thpercentile

Out of 814 buildings in this neighborhood, 122 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.

Neighborhood location

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

DBI complaints, owner's portfolio

Complaints across all of this owner's buildings over 7 years.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.
