Rent & eviction protection

Is 1233 45Th 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 1904
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 property at 1233 45th Avenue in San Francisco's Outer Sunset neighborhood is a two-unit multi-family residential building constructed in 1904, now owned by the Gross Family Revocable Trust. The building underwent significant modifications in 1998-1999, when it was converted from a two-unit structure to a single-family home, with both vertical and horizontal additions completed during this period. The structure has experienced recurring issues with dry rot, particularly in 1990 when repairs were made to both front and rear stairs, and again in 2006 when approximately 350 square feet of siding required replacement. Additional renovations include a kitchen remodel in 2000 involving cabinet replacement and door relocation, as well as various structural improvements typical of older buildings.

Recent activity around the property has primarily involved external maintenance and parking enforcement issues. The most recent relevant service request is from September 2023 for utility excavation work, which remains open, and there have been multiple reports of sidewalk parking violations in the vicinity, with the last recorded incidents in late 2023, though officers were typically unable to locate the offending vehicles. A notable infrastructure issue was documented in September 2016 regarding sidewalk defects, though the investigation found no actionable conditions requiring repairs. The building's maintenance history shows regular upkeep typical of a century-old structure, with no recorded safety violations or major structural concerns in recent years.

Risk rating

How 1233 45Th 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
55thpercentile

Out of 632 buildings in this neighborhood, 284 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.

Neighborhood location

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

Building age

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

Estimated permit spend (past 7 years)

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