Potrero Hill, SF 94103 3961020 5 units · 3 fl · 1906

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 309-315 Potrero 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.

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 1906
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 three-story mixed-use building at 309-315 Potrero Avenue in Potrero Hill, owned by Homespace LLC, was constructed in 1906 and contains three residential units plus commercial space. The property has undergone significant renovations and improvements, particularly between 2012-2019, including extensive plumbing and electrical work, HVAC system upgrades, and commercial space modifications. In 2019, the building had both sewer repairs and the installation of new furnaces for multiple units. The 2013-2014 period saw substantial improvements including bathroom remodels, kitchen installations, and electrical system upgrades across units 311, 313A/B, and 315, along with the conversion of restaurant space to retail/office use.

Recent activity at the building includes multiple 311 calls in January 2025 regarding street conditions such as blocked bicycle lanes and debris, as well as an open public health inspection request. Historically, there was one fire complaint in 2006 regarding blocked exits, which was found to have no merit, and no fire incidents with civilian injuries have been recorded. A short-term rental violation was reported and abated at 311 Potrero Avenue. The building's documented permits and inspections suggest it has received regular maintenance and updates, particularly to its mechanical systems and living spaces, though the frequency of street-related complaints in early 2025 indicates ongoing challenges with the surrounding public right-of-way conditions.

Risk rating

How 309-315 Potrero 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
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.

Model explanation

What's driving this score

Building size

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

Number of units

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

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.
