Rent & eviction protection

Is 41-43 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 before 1979
Built 1900

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 building at 41-43 Prosper Street is a two-unit, two-story multi-family residential structure located in the Eureka Valley/Dolores Heights neighborhood. Built in 1900 and currently owned by the Peneyra Maria A 98 Revoc Tr, this flats and duplex building is undergoing significant renovations as evidenced by the recently filed permit (September 2024) for substantial improvements including kitchen and bathroom relocations, addition of new bathrooms, conversion of a ground floor storage area into an office with bath and wet bar, exterior upgrades including new wood siding and windows, and removal of the rear stair for fire department access modifications. The property has a history of parking-related issues, with multiple documented cases of driveway blocking between 2020 and 2024, resulting in several citations, though some cases could not be validated or located. A notable tenant buyout occurred in December 2023, with the property owner compensating two tenants a total of $95,000. Additional improvements on record include window replacements in 1997 and a water heater replacement in 2007. The property is currently undergoing review for a variance related to rear yard encroachment concerning the proposed stair and landing modifications, with an associated application for renovation and structural retrofit under review by Trichome Architects Inc.

Risk rating

How 41-43 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
70thpercentile

Out of 1278 buildings in this neighborhood, 383 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.

Building permits, owner's portfolio

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