What is an ADU?

Accessory dwelling units (ADUs) are extremely important in combating the housing crisis California is facing right now. Legislation has made it easier than ever for homeowners to add an ADU to their property. An ADU is a smaller, secondary living structure built on the same single-family lot as the primary living structure.

ADUs can range anywhere from 150 to 1200 square feet, giving homeowners plenty of flexibility in how they approach their projects. These structures feature their own living area, kitchen, bathroom, a sometimes more than one bedroom. They may even have their own private entrance and parking space.

Building requirements vary depending on the type of ADU you choose to build. That is why hiring an experienced Los Angeles ADU builder like EcoStar Remodeling & Construction is so important.

Why Build an ADU?

Why do homeowners choose to build an ADU? While not everyone is building an ADU because of the housing market, many are choosing so because of how beneficial it is to them. 

Building an accessory dwelling unit on your property is able to provide:

  • Increased property value
  • Potential passive income from renting
  • Additional living space
  • Eco-friendly and sustainable housing
  • Land conservation
  • Independence for senior family members

In addition to the benefits above, California has required cities and municipalities to create incentive programs for ADU owners. These incentives could include tax cuts, waived fees, or even grants.

Types of ADUs to Consider

EcoStar Remodeling & Construction can bring any ADU design idea you may have to life. When it comes to ADUs, there are three primary types:

  • Interior ADUs
  • Attached ADUs
  • Detached ADUs

Within each of these categories, you have methods in which you can incorporate an ADU into your property.

Interior ADUs

An interior ADU exists within the primary living structure. An interior ADU may also be a junior accessory dwelling unit (JADU), but it must meet specific qualifications. In most cases, an interior ADU is a converted room. Basements, attics, lofts, or even the garage are all suitable options.

Some homeowners choose a garage conversion for their ADU as it helps cut down on building costs. Our team can help you achieve this goal or convert another space into the interior ADU you want and need.

Interior ADUs do not require certain features like a bathroom or kitchen as they will often share with the primary living structure. The same goes for its HVAC system, plumbing, and electrical.

Attached ADUs

Attached ADUs are directly connected to the primary structure by at least one wall, often more. Your attached ADU could be a converted attached garage if you so choose. However, many choose to build them from the ground up at the side or back of the home.

Unlike interior dwellings, attached ADUs will have everything they need for independent living: bedroom, living room, bathroom, kitchen, HVAC system, etc. These types of structures may or may not have a private entrance. In some cases, they may share them with the primary structure.

Detached ADUs

This type of ADU is completely independent and built away from the primary living structure. It will have its own utilities, living areas, entrance, and more. These ADUs are almost always new construction unless homeowners have a detached garage they wish to convert.
