Rent & eviction protection

Is 1737-1751 Balboa 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
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 property at 1737-1751 Balboa Street is a 2-story, 4-unit residential building constructed in 1922, currently owned by the Ng Family Trust 2004. The building has experienced several significant events over the past few years, with the most notable being construction-related issues. In February 2024, there were reports of loud construction activities involving power tools and plywood removal, with complaints about work occurring after dark and potential lack of proper permits. Earlier construction concerns were documented in December 2022 regarding unauthorized work related to a coffee shop's exterior bench structure, and in December 2020 regarding construction at the former coffee shop location. A legitimate building permit was issued in November 2020 for kitchen remodeling and furnace replacement work at 1741 and 1743 Balboa Street, with a recorded construction cost of $36,000.

The building has generated a total of 90 311 service requests over the past seven years, with 31 requests recorded in the most recent year alone (2023-2024 timeframe). While many of these service requests relate to various maintenance issues, parking concerns have been particularly prominent, with multiple reports of illegal parking incidents between March and July 2026, though most of these were either unable to be verified or were resolved with citations. Other notable maintenance issues include a report of overflowing city garbage cans in June 2025. The building has also received three Department of Building Inspection complaints in recent years, though none of these complaints are currently active.

Risk rating

How 1737-1751 Balboa 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.
