Rent & eviction protection

Is 2501-2507 Balboa 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 1921

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 1921
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 4-unit multi-family residential building at 2501-2507 Balboa Street, owned by the Chi Mui Mok Trust, was constructed in 1921 and has undergone several significant renovations over its history. Most notably, in 2009, comprehensive improvements were made including kitchen and bathroom remodels in multiple units, installation of new plumbing systems, electrical updates with new smoke detectors, and the conversion of a dining room into a bedroom with corresponding bathroom modifications, with a total cost of approximately $20,500. The building experienced a serious fire safety incident in 2004 when violations were recorded concerning egress obstructions and combustible storage, though these were resolved within two months. Earlier maintenance work included termite repair in 1996 and rear stair repairs in 1989, demonstrating attention to structural upkeep.

Recent concerns include multiple sewage backup incidents in January 2025, with documented issues from the side sewer vent that required municipal intervention. The property has also been the subject of numerous parking-related complaints in late 2024, particularly regarding illegal parking and driveway blocking, with several citations issued. Historical records indicate a gas leak incident and a false fire alarm, neither resulting in civilian injuries. The building has maintained its residential character throughout its history, with a recent commercial tenant improvement application in 2023 that did not alter the building's facade or use. While the property has had its share of maintenance and compliance issues, recent upgrades and repairs suggest ongoing attention to building maintenance, though the recent sewer issues may indicate potential infrastructure concerns.

Risk rating

How 2501-2507 Balboa 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
23rdpercentile

Out of 2250 buildings in this neighborhood, 1732 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
