    General Information

    Wilton is a small community situated a short drive away from Sacramento.

    Moving to Wilton is a perfect variant for those, who are searching for a comfortable and quiet place located away from the noise and the dust of a large city. It is a suburb with the fresh air, the beautiful scenery and the calm and friendly atmosphere.

    Wilton is the tight-knit community, where people know each other thoroughly. But that’s an advantage, since it facilitates the safety. According to statistics, the crime rate is minimal there. So, you can safely move there with kids.

    Naturally, many Wilton residents are involved in farming. There are dozens of ranches and farms, specializing in producing varied crops and breeding animals. But, since Wilton is situated close to other bigger cities, including Elk Grove and Sacramento, there is a wide selection of job options, you can easily keep working outside the town. For example, the distance from Wilton to Sacramento is about 30 km, and it will take you about 30 minutes to cover it by car.

    Still, one should take into account that to feel comfortably living in Wilton, one needs a car, since the local infrastructure is not so well-developed. There are a few shops and facilities for pets and farm animals, but most locals prefer to drive to bigger cities to do shopping and deal with other routine issues.

    Key Facts about Wilton, CA:
    • Wilton is the census-designated place in Sacramento County.
    • The total area of Wilton is about 75 sq km.
    • As of 2010, the population of this community was 5,363 people.
    • The zip-code of the suburb ― 95693.
    Things to Do in Wilton

    Although Wilton is a small town, the local life can hardly be called boring. There are a lot of facilities that enjoy popularity among both locals and guests from neighboring towns and cities:

    • Fog Willow Farms. Many US citizens make a trip to a farm every year before Halloween in order to join celebrations and to choose pumpkins. But a visit to the local Pumpkin Farm is a completely different experience, since this place is transformed into a real entertaining center for the entire October. Little visitors can have fun climbing the giant haystack, see and feed more than 50 farm animals, take tours by creative trains, ride a pony and enjoy lots of other exciting activities. Sure, the farm also offers souvenirs and delicious bites, including classic caramel apples. There is also the Science Farm, where kids of different age (including pre-school) can explore physics, chemistry, biology and more by watching the life of animals and taking part in fascinating and entertaining experiments. Such lessons will definitely encourage them to pay more attention to studying and to broaden the outlook.
    • English Rose Farm. It has been operating in the community for more than 15 years and has established the reputation as the facility with the top-quality service and high safety standards. Besides traditional riding lessons, it offers special training programs for those, who take horse breeding seriously and plan to engage their lives with it. For example, you can take equine first aid lessons there. By the way, if you own or plan to buy a horse, you can use their boarding services.
    • Hawthorn Ranch. That’s another popular horse riding spot in Wilton, which provides personal and group classes for jockeys with different experience. This ranch boasts an extensive territory covering 20 acres. There are varied riding arenas, including the ones equipped for jumping and other tricks. And if you do not have the opportunity to enjoy riding during the daytime, you can use a special illuminated arena.
    • The Alta Mesa Gun Club. This is the non-profit family organization that conducts regular shoots that are open to the public and promotes shooting sports, including trap shooting. It is the place, where locals come to spend some time together with friends and families and to match aiming accuracy with each other. It is truly crowded on weekends and holidays.
    • Brave Horse Winery. Winemaking is one of the key industries in California, so, if you live in this sunny state, to taste at least a couple of local wines is a must.
    • The clothing-optional resort Laguna Del Sol. There are four different pools, a fitness center, tennis courts, volleyball courts, shuffleboard areas, pool tables, a ping pong table and other amenities for playing sports, exercising and just relaxing. There is even a dog park.

    Certainly, in Wilton, there are also other farms and ranches that offer varied training and entertaining options.

    Since Wilton is a rural place, most local facilities are connected with farming and breeding animals. So, the diversity of activities is limited. But, if you prefer to spend free time in a different way, you can always take a drive to Elk Grove, Sacramento or other city located nearby. There are so many varied attractions in the Sacramento Area.

    ADU Building Wilton

    Prior to starting the construction of the addition to a single-unit dwelling, you need to submit some forms to the building department of the city. Moreover, various zoning rules of your neighborhood must be followed in constructing the ADU in Wilton, Sacramento, CTY.

    The minimum lot size for putting an ADU on it is not regulated. However, your property must be appropriate for residential purposes. Owners of single-family houses are allowed to build 1 or 2 accessory dwelling units, while multi-family residences can have more than 2.

    Each accessory dwelling unit (ADU) must be of the same architectural style, color, and building interior as the primary single-family or multi-family housing unit.

    Standard ADU cannot be less than 150 square feet and cannot exceed the size of 850 square feet (in some cases, 1000 square feet). The maximum height of a detached or attached ADU is not regulated anyhow. The floor area of the latter must not be bigger than 50% of the primary residence size.

    There are some setback requirements as well. Multi-story detached and attached ADUs must have no more than 4 feet of the side yard and rear yard setback. One-story ADUs and those with lot coverage less than 800 square feet do not comply with such setback requirements, but they have to be placed no less than 60 feet from the front property line. A multi-story accessory building does not have to follow the property line rules. Converted ADUs do not have to meet any setback requirements (no side yard or rear yard setback needed).

    If your primary residence is located half a mile distance from public transportation, there is no need to have an additional parking space for ADU. Moreover, if the accessory dwelling unit (ADU) was converted from a garage, there is no requirement to substitute it for another one either.

    No special fire safety equipment is a must, but the owner is advised to provide some kind of fire protection.

    Prefab ADU Construction

    All of our attached junior and detached ADUs are prefabricated in order to make our services quicker. We assemble them near the city of Sacramento, CTY. This way, the contractor’s work on your property is as minimized as possible, so you cannot be disturbed by the building noise as much as possible.

    If you have any questions on how and where your contractors create the ADU, you can ask them during a free online consultation with our specialists.

    ADU Housing

    Having attached converted, junior or detached ADUs on your property is very convenient, as you can turn the space into anything you would like. Here are some options on how you can use your accessory building.

    Personal office

    Having the office at your property is very comfortable for those who are working from home or just need a private space to go about their business. A place different from your home environment and no drives all across the city permit you to be at your best working conditions right at your back or side yard.


    If you are used to having a lot of visitors regularly, then this is the best option for you. Use your accessory lot coverage to accommodate your relative from another city or to have friends stay overnight. This way, you would be comfortable in the privacy of your house and still be sure that your guests are having a great time.

    Renting the place

    Another alternative is to rent your ADU to someone and get a stable source of income. It is even more comfortable than leasing a usual apartment or house in the city: you can supervise the place as it is on your property line and be sure that it is treated properly by the resident.

    Home for the elderly

    Those of us who have old parents or relatives are probably familiar with the problem of not being able to take regular care of them, because of the long distances between houses. Having ADU solves such an issue. You can move your elderly to the place right by your side and be sure they are safe and sound.
