Rent & eviction protection

Is 309 28Th 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.

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 1905
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, two-story multi-family residential building at 309 28th Street in Noe Valley, owned by Douglas Melton, was constructed in 1905 and has undergone several significant improvements over the past few decades. Most notably, between 2018-2019, the property received substantial upgrades including a complete roof replacement (costing $80,000 combined for two permits), the installation of a solar power system (10.08 kW), and an electrical service upgrade to 200-amp capacity. Earlier improvements included the addition of a curb-mounted skylight in 2018, installation of an EPA-certified wood stove in 2014, and window and door replacements in 2005.

The building has a history of addressing maintenance and safety issues, with records showing foundation work in 1998 and termite damage repairs in 1987. Between 2015-2016, there were multiple environmental health-related service requests and complaints, as well as a building inspection complaint, though these cases were ultimately resolved or transferred to appropriate departments. The property has maintained active compliance with building codes, as demonstrated by the completion of all recent major improvements, including solar installation and electrical service upgrade. Historical permits indicate regular maintenance, including roof work in 1998, window replacements, and various structural improvements, suggesting ongoing property upkeep by the current ownership.

Risk rating

How 309 28Th 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
87thpercentile

Out of 1879 buildings in this neighborhood, 244 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.

Building age

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

Building permits, owner's portfolio

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

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.
