Rent & eviction protection

Is 1229 45Th 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.

Built 1903

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 1903
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 1229 45th Avenue in the Outer Sunset neighborhood is a two-unit, two-story residential building constructed in 1903, currently owned by Labatt LLC. The building has undergone several significant changes and faced various maintenance challenges over the years. Most notably, in 2021, there was a filed permit for the replacement of an existing garage with a new 4-story, 3-bedroom ADU at the front of the lot, utilizing the local ADU program, while retaining the two existing units at the rear. In late 2020, multiple building violations were issued regarding weather proofing and lead paint hazards on the building's siding, which were abated by February 2021 through completed repairs costing $3,000. A concerning complaint was filed in November 2020 reporting that both the garage and main house were dilapidated, with plumbing issues allegedly leading to improper waste disposal. Historical records show structural concerns from 1996, including damaged support beams and security issues, though these were promptly addressed. The property has experienced multiple parking enforcement issues in recent years, with several citations issued for sidewalk parking and blocked driveways between 2019 and 2024, as well as some cleanliness concerns in the surrounding area.

Recent planning records indicate ongoing interest in improving the property, with discussions about potential development options to add more housing, including the possibility of constructing additional ADUs within existing structures or the buildable area of the lot. The property has a documented history of maintenance challenges, particularly related to weather proofing and paint conditions, suggesting ongoing concerns with building envelope maintenance. The garage and main building have both been subject to various repairs and proposed improvements over the years, indicating active management of the property's maintenance needs and compliance with local housing regulations. The most recent building permit activity, focusing on ADU development, reflects current trends in San Francisco housing development and the property's potential for modernization and increased housing capacity.

Risk rating

How 1229 45Th 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.
