Rent & eviction protection

Is 4740 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 before 1979
Built 1928

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.

Annual rent increase cap

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

4740 Balboa Street is a 4-story, 35-unit multi-family residential building constructed in 1928, currently owned by 4740 Balboa Street LLC. The building has undergone significant renovations and improvements over the past several years, including a completed $19,000 installation of low-frequency horns in sleeping areas in 2024, comprehensive unit remodels in 2019-2020 (Units 302, 402, 503, and 304), exterior siding replacement on the west elevation in 2019, and major electrical system upgrades in 2018 including the installation of a 400-amp service with 38 meters. The building's safety systems have been a recurring focus, with recent violations in 2023-2024 related to alarm systems and fire extinguishers, though these issues were subsequently addressed or abated. The property completed its soft story retrofit requirements and has maintained compliance with building codes.

Historical building complaints from 2001-2017 included various interior maintenance and safety issues, such as ventilation problems, floor covering repairs, and plumbing violations, all of which were abated. More recent complaints from 2018 and 2020 raised concerns about construction practices, including dust containment and debris disposal, though these issues were addressed through inspections. The building has experienced periodic issues with garbage and debris in the surrounding area, as evidenced by numerous 311 calls in 2024, though these appear to be primarily related to street maintenance rather than building management. A tenant buyout record from 2019 shows a payment of $12,000 to one tenant. Recent improvements include the installation of 35 low-frequency horns in 2023 and consistent upgrades to individual units, suggesting ongoing maintenance and modernization efforts by current ownership.

Risk rating

How 4740 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
2ndpercentile

Out of 1040 buildings in this neighborhood, 1019 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Neighborhood location

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