What Is an ADU?

Accessory Dwelling Units (ADUs) are secondary domiciles on a property. They’re sometimes called guest houses, casitas, granny flats, or in-law suites because they’re perfect for hosting family members, but they can be rented out as well. They can be detached or attached to the main house, but they always have their own amenities. They can be custom-built, but garage conversions are popular for making ADUs, too. However, these options involve considerable expense and a lengthy permit and entitlement process. This is where these plans come into play.

Understanding Pre-Approved ADU Plans in California

The increasing cost of living in Southern California has caused municipal and state authorities to look for ways to encourage housing development. One of the solutions they found is by pre-approving standardized ADUs. For example, the Los Angeles Department of Building and Safety has its Standard Plan Program, which has approved standardized structures from many design firms, including Complete Package Drafting. Other municipalities in Southern California have their own pre-approved structure programs. They ensure compliance with building, residential, and green codes, greatly reducing the time to obtain building permits. Usually, the overseeing authority needs to complete only an evaluation for each specific site to ensure compliance with zoning laws and foundation requirements.

These plans have undergone rigorous evaluations by local authorities, ensuring they comply with the latest safety codes. By opting for a pre-approved structure, you’re not only expediting the permit process but also gaining the confidence that your project aligns with California’s building requirements. And “pre-approved” doesn’t mean “boring.” We will still work tirelessly to ensure your ADU reflects your style and aesthetic vision.

What Pre-Approved ADU Plans Do We Offer?

Complete Package Drafting currently offers two such plans in Los Angeles.

The first is a one-story, one-bedroom, one-bathroom 600 square-foot domicile perfect as an in-law suite or guest house. It is affordable and easy to build, and it is ideal for owner-builders looking to generate a new income stream. All work is per WFPP, which is the standard and most common construction.

The second is a two-story, three-bedroom, three-bathroom 1200 square-foot house that blends so well with single-family homes in Los Angeles that it is often mistaken as the primary domicile. It is not an ugly box, but a beautiful home, complete with planters, multiple entrances, and a balcony.

We are working to offer our pre-approved ADUs in other parts of Southern California, but if you are in Los Angeles or Burbank, please contact us to learn more.
