Accessory Dwelling Units in California: What To Do and Not To Do

The popularity of accessory dwelling units continues to rise across California. An accessory dwelling unit, or ADU, is a residential unit that is secondary to a primary housing unit on a lot. Accessory dwelling unit is simply the legal term for what are commonly called granny flats or in-law suites. ADUs can provide much value to you as a homeowner. But to get the most out of your ADU project, careful planning and consideration are required, including strict adherence to California accessory dwelling unit laws.

Our design team has extensive experience helping property owners create the ADUs of their dreams. Here are some of the do’s and don’ts when it comes to planning your accessory dwelling unit in California.

Accessory Dwelling Unit Best Practices

Whether you plan to add an addition to your home, build a separate space on your lot, or convert a basement or garage into an ADU, here are some of the best practices for ensuring a smooth and successful accessory dwelling unit construction project in California:

Follow Local ADU Regulations

California is a very ADU-friendly state. In fact, recent legislation passed to make it easier than ever for property owners to maximize the value of their lots through accessory dwelling units. Still, it is vital to research local laws and regulations pertaining to accessory dwelling units in California. Regulations and requirements can vary significantly based on location when it comes to size limitations, parking requirements, setbacks, and other unit specifications.

Maximize Use of Space 

Maximizing the space of your ADU is essential for maximizing both its value and its function. One way to achieve this is by furnishing your unit with multifunctional furniture, such as futons and bunk beds. You should also think of ways to get creative with storage space. When it comes time to paint the interior, we recommend cool, light colors that can add depth and make smaller spaces feel larger.

Implement Universal Design 

California property owners commonly use accessory dwelling units for aging parents or other relatives who may be seeking the solitude of having their own space while having the safety and security of being so close to their loved ones. Even if you don’t plan to utilize your ADU for this purpose, it can be beneficial to design your unit with universal design in mind. This can increase its value and appeal to potential buyers down the line while also providing you with flexibility in the event that your plans for the unit change. Examples of universal design include accessible bathrooms, wide-frame doorways, zero-step entrances, and entryway ramps.

Work With Reputable Designers and Builders

Choosing the right partners for your ADU project can make or break its success. Working with qualified contractors who are experienced, knowledgeable, and insured is essential for ensuring work remains on schedule, stays within your budget, and follows all California accessory dwelling unit regulations and requirements.

Accessory Dwelling Unit Faux Pas

There are many benefits of adding an accessory dwelling unit to your property, but it can be easy to get caught up in the excitement of your ADU project and overlook some of its crucial details. Here is what you must avoid in order to ensure you get the most out of your accessory dwelling unit:

Ignoring Aesthetics of Neighborhood

Your ADU shouldn’t just fit the style of your own home. Factoring the aesthetics and architecture of your neighborhood into your ADU plans is vital for not only being a courteous neighbor but also for maintaining the value of your own property. An unsightly addition can decrease its value and minimize the value of your investment. If your neighborhood has an HOA, it is important to learn the construction rules of your community, as they may differ from your local municipal regulations and requirements.

Overlooking Maintenance Costs

While it is true that accessory dwelling units create value for California property owners, that value still comes at a cost. In addition to the upfront design and construction costs associated with an accessory dwelling unit in California, it is important to not overlook the costs of long-term maintenance. Just like any other unit, an accessory dwelling unit will require both planned and unplanned repairs throughout its lifetime. Factoring in the costs of this maintenance is an important part of the planning process.

Using Cheap Materials and Furnishings

A common mindset we find California property owners falling into is that the accessory dwelling unit is a secondary unit, and therefore not worthy of being built with quality materials or outfitted with quality fixtures. Treating your accessory dwelling unit as you would your primary residence will not only ensure the best value for your investment but also ensure the best experience for those living in the unit.

Not Acquiring Proper Permitting

Even the smallest non-compliance can spell big trouble and big costs for your accessory dwelling unit project in California. Acquiring the proper permitting is essential for maintaining compliance and avoiding any unexpected interruptions or fines. This is where a reputable team like 5blox can help.
