Rent & eviction protection

Is 66-68 Prosper 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 1900

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.

15+ years since occupancy
Built 1900
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 residential building at 66-68 Prosper Street in the Eureka Valley/Dolores Heights neighborhood is a two-story flats and duplex structure built in 1900, currently owned by Jeffrey & Jennifer Suffin F. The building's maintenance history shows consistent upkeep, with significant work completed on various structural elements including reroofing ($22,300) in 2007, front step repairs in 2008, and back stair repairs in 2010 (both $2,000). Earlier improvements from the early 1990s included earthquake safety measures with anchor bolts and plywood sheathing installation, followed by bathroom remodeling and window repairs, though these permits ultimately expired.

The property has experienced recurring parking-related issues in recent years, particularly during 2024, with multiple citations issued for driveway blocking, suggesting ongoing challenges with street parking management in the area. Other reported incidents include two cases of human or animal waste on public property (one resolved in December 2021, another in September 2022), an accepted sidewalk parking enforcement request in November 2021, and a noise complaint in July 2021. While these issues have primarily occurred in public spaces rather than within the building itself, they may impact the general environment around the property. The building's maintenance record indicates regular attention to structural elements, though the expiration of several permits from the early 1990s suggests some historical work may have been completed without proper follow-up documentation.

Risk rating

How 66-68 Prosper 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
77thpercentile

Out of 1278 buildings in this neighborhood, 294 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.
