Rent & eviction protection

Is 21 Alta 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.

Annual rent increase cap

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-story, four-unit building at 21 Alta St in Telegraph Hill, owned by John P Early Declaration Of, has experienced several significant safety and maintenance issues over recent years, most notably in March 2021 when multiple violations were documented. These violations included concerns about fire safety equipment, with inspection requirements for fire escape ladders and issues with a stuck window leading to the fire escape. Additionally, a complaint was filed regarding blocked secondary egress in unit 21D, where roof flashing allegedly impeded window operation, though this complaint was subsequently resolved by May 2021. The property has also faced concerns about child safety, with violations recorded regarding fully opening windows in the living room area, though these violations are now listed as not active.

In terms of recent activity, the building has generated numerous 311 service requests, with six reports of blocked sidewalks by Lime scooters between July 25 and July 30, 2026, all of which were resolved. The building's history shows a total of 27 311 service requests in the past seven years, along with one Department of Building Inspection complaint, five Notices of Violation (including one Final Warning Notice), though it's worth noting that all of these violations are currently listed as not active. While the property has had multiple violations in the past, recent records indicate that the owners have addressed these issues, as none of the current violations remain active.

Risk rating

How 21 Alta 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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
