El Dorado Hills ADU Builders

The law of El Dorado County allows attached ADU, separate ADU property, Junior accessory dwelling unit. The ADU can be either an extension to the room or a separate building. But JADU should be a reconstruction of an existing space.

  • Lot Size Restrictions

  • Allowed ADU property amounts  in Northern California

According to state laws, one family can build at least one accessory dwelling unit, depending on the lot size. An owner who has a single-family property can build one ADU extension and one JADU building.

In the case of apartment buildings, for every four residential units, tenants can build one ADU property if it is agreed by law.

  • Allowed size of single-family ADU building

For a single ADU, there is a limit for a building area of 850 sq. ft., and for a double ADU up to 1000 sq. ft. For JADU, there is a limit of up to 500 sq. ft. And according to the laws of the state of California, the minimum size of the living space must be at least 150 square feet.

  • Zone of parking

Parking does not apply to plots that convert a garage into an ADU living space or Junior Accessory Dwelling Unit.

  • Materials, shape, and style

There are no prohibitions on construction, materials, and style of ADU property in El Dorado County, California.

  • Fire protection of existing space

According to state requirements, the ADU building will not be equipped with conventional sprinklers protecting from fire if they are not needed for housing. You can use classical methods of protection.

ADU Contractor El Dorado Hills, CA

Why do you need to build an additional living space? Perhaps at first, it will seem to you that accessory dwelling unit is an absolutely useless construction investment, that it will entail only additional expenses and a minimum of positive aspects. We will try to change your opinion on this matter and show what the advantages of such buildings are.

1. Increase in market value

The price of such buildings is constantly moving forward. Creating an ADU building on your building site will significantly increase its value when selling. If this building looks good, the price will increase several times in the eyes of the realtor. A+ Remodeling will help you in creating your ideal extension to the house in El Dorado Hills, CA.

2. Rental income

Very often, young people who have just entered high school are looking to primary residence for the academic year. The problem is that their funds are limited. Often in such a situation, they are helped by homeowners renting out their small ADU building for an affordable price. Why don’t you go in the same direction?

3. House for guests

If you are often visited by friends, and they want to stay for a period date, it will not be very convenient to place them in your house. Family members will be much more pleasant if they have their own kitchen, bedroom, and bathroom. And you will be able to enjoy the pastime with the opportunity to have a personal space.

4. Place of residence for your parents

Granny flats are a very popular concept in the USA. Sometimes it happens that it is difficult for old people to live in a big metropolis, maybe they need care, and they will be much more comfortable living with their children and grandchildren. But it is very uncomfortable for multi-family to live in the same house because your parents are already pretty tired of the energetic working pace of life. Giving them a place in your ADU building is a great idea. Therefore, if you face such a situation, you will need to think about granny flats.

5. Using the accessory dwelling unit as a workshop, home office, or garage

If it happens so often that you need to work remotely, your job is to use noisy instruments, or your hobby is playing an electric guitar, and all residents are tired of listening to the noise, it will be more convenient to have a separate space away from home and be the owner of your place. With the help of ADU property, you can easily change your home environment to work. A+ Construction & Remodeling will help you to equip an extension for your hobby.

General Information

El Dorado Hills is a lovely CPD with a 42K population (based on 2010 data). It is located in El Dorado County, just 35 km far from Sacramento, and 90 minutes by car from the Lake Tahoe.

It fits those who are into a rural style of living mixed with modern designs of houses and apartments.


The county is located just about 18 miles from the Gold Rush spot — Coloma. It was believed to be home to Maidu, Washoe, and Miwok tribes of Native Americans.

Speaking of the modern stage or history of this place, it dates back to 1960 when Alan Lindsey, started developing the county as a master-planned community in the form of villages with parks, educational facilities, shopping malls, business centers as well as a golf course. Many people from outside areas contributed to the building of this beautiful, practical, and convenient spot where both families and youngsters may find a thing to do.

More prominent development started later approximately in 1970–1990 when people from Sacramento or nearby counties started relocating there to reside in the village-like community or send their children to one of the best schools in California. As of now, El Dorado Hills may boast mixed infrastructure which accommodates movie theatres, hotels, premium car distributors, medical facilities, fountains as well as waterways.
