Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Rent & eviction protection

Is 1030 Carolina 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 1912

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
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 two-unit, one-story multi-family residential building at 1030 Carolina Street in Potrero Hill, owned by Michael F Hirner, has a documented history dating back to 1986. The property, built in 1912, has faced several maintenance issues over the years, with the most significant concerns centering on deck maintenance and water drainage problems. In 2010, there were multiple permits issued for addressing dryrot at the deck, including both a demolition to assess the extent of damage and subsequent repairs costing approximately $7,000. This period also saw a complaint about improper drainage affecting neighboring properties, though this issue was marked as abated in 2012. Earlier structural improvements included a 2008 garage door replacement and an electrical service upgrade from 60A to 100A. The building has undergone necessary systems updates, including a furnace replacement in 2013.

The property's maintenance history shows regular upkeep, with improvements including window installations in 1987 and 1988, reroofing work in 2005, and various interior renovations. However, there were two notable complaints filed regarding unauthorized work: one in 2008 related to garage door modifications, and another in 2010 concerning deck repairs and drainage issues. More recently, there has been a recurring pattern of parking violations in the vicinity of the property between 2019 and 2024, with multiple citations issued for sidewalk parking and driveway blocking, though these are unrelated to the building's structural or maintenance history. The building's documented permits and repairs suggest ongoing maintenance, though the concentration of deck-related issues in the 2008-2010 period stands out as the most significant structural concern in the building's recent history.

Risk rating

How 1030 Carolina 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
28thpercentile

Out of 726 buildings in this neighborhood, 523 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Building age

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