318 Prospect Ave

Bernal Heights, SF 94110 5672004 3 units · 2 fl · 1905

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 318 Prospect 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.

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-unit residential building at 318 Prospect Avenue in Bernal Heights, owned by Michael J Raifsnider, is a two-story flats and duplex structure built in 1905. The property has undergone several significant renovations and maintenance work over the years, with the most recent being a complete reroofing project valued at $20,000 that was completed in July 2024. Historical improvements include a second-floor bathroom upgrade in 2007 (with associated plumbing and electrical work), extensive kitchen renovations in 2005, and substantial exterior work in 2006 that encompassed stucco removal, siding repairs, and front stairs/porch renovations. The building has had multiple permit renewals in 2006, suggesting careful attention to completing various construction tasks.

Recent incident history shows relatively few concerning events, with the most significant being a fire complaint in May 2021 that was determined to have "no merit." There have been periodic issues with parking violations and sidewalk access, including a blocked sidewalk incident in July 2024 involving construction materials, though this was promptly resolved. The property had one known variance case regarding unauthorized utility porch and stairs construction, which has been closed and approved. Multiple 311 calls in recent years have primarily related to routine urban maintenance matters such as waste disposal and parking enforcement, rather than any direct building-related issues. The building's maintenance record shows regular upkeep, with no significant safety or habitability concerns having been reported through official channels.

Risk rating

How 318 Prospect 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
23rdpercentile

Out of 1276 buildings in this neighborhood, 983 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
