Rent & eviction protection

Is 50 Highland Ave rent-controlled?

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 1990
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
May be covered by AB 1482. The building is old enough for the statewide rent cap (5% + regional CPI, capped at 10% per year) and just-cause protection after 12 months of tenancy.

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 50 Highland Avenue in Bernal Heights, owned by Chen Selina He, was constructed in 1990 and includes two stories. The building's permit history shows proper initial construction with permits for both the building itself and the installation of sprinklers in 1989, totaling approximately 300 units of cost. A significant compliance issue arose in 2007 when an unpermitted property line window was installed on the northwest side, measuring approximately 2 feet by 4 feet, resulting in a violation notification. The violation was resolved by March 2008 through the proper closure of a window opening (3'x3') under permit number 200711087712.

In recent years, the property has generated multiple service requests, primarily related to rent board inquiries and street cleaning matters. Between 2022-2024, there have been several interactions with the Rent Board regarding fee housing inventory issues, including a request resolved in August 2024. The property experienced some exterior maintenance concerns in 2024, with reports of garbage and debris on or near the property. Historical records show occasional abandoned vehicle complaints in the vicinity between 2019-2020, though these were addressed promptly by enforcement agencies. A construction noise complaint was filed in August 2022, which was transferred for tracking through official channels.

Risk rating

How 50 Highland 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

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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Neighborhood location

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

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

12-Month severity forecast
No violation 20.0%
Moderate concern 11.5%
Severe concern 68.5%

DBI Complaint Jul 13
At approximately 1:25 a.m. on sunday, july 12, 2026, i heard what sounded like drilling or powered mechanical work and felt vibration coming from the locked ground-floor/garage-level space directly beneath my apartment at 50 highland avenue.i went briefly into the building¿s common hallway to determine where the sound was coming from and asked whoever was present to stop and identify themselves. no one responded. i could not see inside the locked ground-floor space, so i do not know who was there or exactly what work was being performed. i returned to my apartment and locked the door.this ground-floor space is currently the subject of open dbi complaint no. 202657408 concerning possible illegal conversion, work without permit, plumbing installation without permit, and illegal change of use. a dbi reinspection is scheduled for july 14.i am reporting this as possible overnight construction or mechanical noise occurring outside normal construction hour...(311 sr 10100441946)
