        • 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.

        • Setback

        Setbacks will not be necessary for JADU and ADU that have been converted from an existing space if it is legally formalized. The maximum possible setback for a detached ADU is no more than four feet from the rear and side property lines.  Transformations from existing space and attached ADU will expand only if there is a lack of a base zone for single-family homeowners.

        • Height

        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.

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.
