M-520: 1 Bedroom 520 SF ADU

Nowadays, the popularity of tiny but complete independent living facilities is growing at an incredible speed. A considerable number of homeowners prefer them to larger houses because of their lower maintenance, costs, and fees. So, a one-bedroom 520 sq. ft. accessory dwelling unit is an amazing choice. This type of building can be suitable for your aging relatives, grown-up children, guests, distance work, renting out, and so on. ADU plans can have wheelchair access for people with certain disabilities. And if you need extra storage space, you can construct a house with a loft.

Some people might have concerns that such tiny homes are uncomfortable. But that’s not true at all! A small ADU is a complete house with a foundation, all the utilities, a bathroom, one or two bedrooms, and a kitchen with cabinets. If you plan its space the right way, it can become very comfy and convenient.

Note that a home’s size doesn’t necessarily impact its quality of life. Just define your own priorities and design goals, get rid of clutter, and maximize the use of every square foot – and you’ll manage to create a charming, cozy retreat that will inspire and energize you for a happy and productive life!

520 square feet ADU project

An accessory dwelling unit (ADU) is a second house situated on the same property parcel as the primary residence.

The sizes and shapes of ADUs vary greatly. According to the California ADU program, there are several types of ADU plans. Here’s a short review of the most popular ones among property owners:

1. Detached ADU. Such ADUs are complete independent living facilities standing separately from the main house;
2. Attached ADU. These structures have a connection with the primary residence of the property owner via a common wall;
3. Converted ADU. Such ADU plans are basically pre-existing structures (such as garages) converted into a living space with a bedroom (or several bedrooms). It’s much easier to create on a property parcel, even without a contractor. But, contrary to a common opinion, you’ll still need to submit to all the requirements and get a pre-approved city/county permit. Without permits, such a construction will be against the law;
4. Junior accessory dwelling unit (JADU). These are very small ADUs, no more than 500 sq.ft. Building permits of California allow property owners to build such a construction in addition to a classic ADU.
