        You might have been born in Cold Springs, El Dorado County, or have chosen this town for its farming opportunities, area’s nature and landscapes, cozy cottage homes, friendly small population, smaller costs, or any other reason. But how affordable is it to acquire one more house in the area if your family has expanded? If the children have grown up and now need their own living space to settle in?

        Building accessory dwelling units is a way of staying within a familiar community in California! Be it a brand-new construction or the conversion of an unused garage, the price of an ADU is something that can get you interested. Pick trustworthy ADU builder and embark on a journey of ADU construction!

        ADU Builders Cold Springs, CA

        Construction projects range depending on accessing the main house, construction method, size, etc. Here are a few ADU options you might request from the ADU builders to erect on your lot:

        • Completely detached ADU

        This type of ADU project is to be built in the form of a tiny cottage suitable for single men and women, families with kids, grandparents, guests, and everyone else who is not alien to privacy. This secluded place has all the amenities of a large home but is assembled in a compact space.

        • Attached ADU/Home addition

        Among common requirements, it is worth singling out this option. Also called “pop-outs,” these accessory dwelling units are basically several rooms (or sometimes floor) additions adjacent to one of the primary house walls. However, as one of the building requirements, ADUs must have their own separate entrance.

        • Garage conversion

        If your car racing days are in the past, make use of the idling garage space! Make it into a new small house by adding a few features to the already constructed walls and roof.

        • Basement conversion

        Such an ADU can only work if you have a big basement (no less than 150 sq. ft.). But in case you do, a basement floor can be adopted for in-law suite or granny flat purposes and work well for those who want to be close to their elder relatives.

        • JADU (Junior ADU)

        The last type of small home is the diminished 500-square-foot ADU. It also has a kitchen, a bathroom, and a sleeping area. But in contrast to the full-sized detached and attached ADUs, they can only be converted from other construction.

        ADU Contractor Cold Springs, CA

        The ADU building process covers not only construction work but also picking materials and furnishing. It includes the planning stage, at which an entire team consisting of an architect, an engineer, and a designer develops detailed plans for new homes. It includes people with expertise in acquiring permits for your building projects from the local government. And it also encompasses an essential cost estimate – a very important point that must be considered in advance for you not to find yourself in the pitfall of outstanding debts.

        To make the ADU building process easy and enjoyable, you should entrust the process to skilled contractors with years of experience in the ADU building area. Building an ADU that will last is a task A+ Construction & Remodeling is capable of fulfilling!

        ADU Contractor Cold Springs

        So, what exactly is required from a professional ADU contractor in El Dorado, and what criteria must they comply with?

        • Experience

        It takes years of experience to master an ADU-creating skill with due diligence. There are just too many riffs on the way of your boat to sail smoothly, unaware. Starting with the fact that even at the stage of making a decision about the construction of accessory dwelling units, you must know whether it’s allowed at all, how many ADUs a single-family lot may accommodate, etc. Too many vicissitudes on this thorny path? A+ professionals will help with it all, employing their rich experience in dealing with El Dorado laws and regulations and permissions from local Cold Springs authorities.

        • In your city/сlose proximity to your city

        Do particular contractors operate in your city? It is literally the first question that must come to your mind when picking an appropriate builder. It’s an essential factor when it comes to ADU-making. Because you want to hire those ADU contractors who are aware of the local construction standards, a good idea may be to check the service areas and cities of the ADU contractors before you start working with them. On the A+ Construction & Remodeling website, you can do this either by finding your city in the list or by typing in your zip code/st/rd.

        • Meet time requirements

        Few things show professionalism as well as the ability to correctly calculate deadlines and follow them. What A+ Construction & Remodeling clients appreciate is that we build and design homes within a stipulated time period. Promptly finishing is our priority, as we understand there are many other things worth spending time on.

        • Always available for clients

        No matter what difficulty you face, A+ contractors are willing to consult with you about labor costs, funds required, quality of materials, the best ways to build an ADU for long-lasting service, etc. After all, it’s way easier to get to the bottom of the wisdom of construction and design when experts share their experience with you.

        ADU Unit Construction Cold Springs

        Before starting your change, review the following characteristics of the ADU homes that are permitted in California:

        For single-family homes, owners may have one full-size ADU (attached or detached) or one full-size and one junior ADU if their plot of land is owner-occupied. For multi-family homes, El Dorado laws permit two detached ADUs on a multi-family land plot.

        The ADU can be decided by the family, but it must not go beyond the limits established by law. For a full-fledged ADU in El Dorado, it’s 850–1000 sq. ft. (for one bedroom and for a two-bedroom ADU), and for a JADU, it’s 500 sq. ft.

        The minimum lot size, as well as ADU materials and design, are not specified by regulations.

        Benefits of ADU Building

        With all being said, ADU conversion or new construction provides certain benefits for an ADU owner, be it extra space or money earning. Successfully performed ADU projects will help with the following:

        1. Serve as a small home space for occasional guests

        Are you an ardent fan of inviting friends from another city to spend the weekend with? If that’s the case, additional space solicitously prepared for guests in advance, with an extra bathroom, kitchen, and bedroom will only ameliorate your hospitable image.

        1. Serve as a dwelling space for newcomer family members or older generations

        When one’s looking forward to family replenishment, one may occasionally forget to steel themselves to the drastic reduction of living space. More so, small kids, as well as elderly parents and grandparents, demand constant care and supervision. If you build a comfy, small, and budget-friendly ADU, you’ll be able to kill two birds with one stone.

        1. Create room for remote work, workshop activities, and hobbies

        With the arrival of the pandemic, many employers have discovered that the physical presence of employees is not necessary at all. Therefore, if you are one of the people working from home, you need to take care of a quiet area where no one will bother you. The same applies to the case when you are engaged in the manufacture of things, buying, or other activities while running a business from home.

        1. Easy and effortless way to add to your monthly income

        Many homeowners throughout the United States have already found a way to make money from ADU rent. The overall sum will depend on the city or town you live in and the availability of education, health, and entertainment facilities. And, of course, your small home’s size and design.

        Cold Springs ADU Construction Company

        To bring your ADU projects to life, a homeowner should choose a reputable ADU builder. A+ Construction & Remodeling combines time-tested quality with the achievements of modern construction.

        At this point, don’t overlook the following features that A+ ADU builder has to offer.

        Licenses, reviews, and project gallery

        The company’s image is built primarily on the trust of customers. Therefore, you can find licenses, certificates, and documented awards on the A+ Construction & Remodeling website. Here at A+, we’re very proud of our past accomplishments because we managed to make your clients happy. Also, new potential customers will get the opportunity to review what home improvement and design projects A+ contractors have already managed to implement.

        Free Estimate

        Before you start to build, create an economic base – this is a rule of thumb for a successful project. Aware of clients’ needs for transparency, the absence of hidden costs, and the predictability of the budget, A+ contractors offer a free on-site evaluation.

        Clear agreements

        A+ contractors plan every individual ADU project as effectively and efficiently as possible. Willing to rigidly stick to deadlines and not miss any of the agreed works, A+ representatives create an elaborate proposal detailing all the verbally mentioned terms.

        Modern technologies

        Do you want to know how your ADU would look if it were built? The good news is that design software does not stand still. Thus, A+ contractors refuse to miss out, offering 3D visualized plans of the ADUs as well as a showroom for more detailed design work.

        Building an ADU in Cold Springs

        The ADU construction process resembles erecting a whole home, but in a downscaled version. So, any reviews won’t convey the thorough depth of customer concern before the ADU-making process starts. However, as you know, the best way to deal with anxiety is with a well-thought-out plan.

        Therefore, A+ Construction & Remodeling offers to your attention several steps toward ADU building:

        • Primarily consultation. A+ contractors outline what is to be done, give an idea of the possibility of such a construction, offer the best options, discuss the list of works, and pre-calculate the costs.
        • Free estimate. A+ contractors assess the amount of work, determine the required amount of materials, and calculate the cost in detail.
        • Preparation and planning. Here, A+ contractors offer to decide on configuration, make up a floor plan, visualize it on demand, and pick the design.

        Prefab ADU Construction

        If there are not enough funds for a full set of services and an additional unit is simply necessary, it’s no trouble! ADUs are, first and foremost, intended to be affordable housing. Therefore, it is possible to order such a unit, avoiding the most expensive part: individual project development.

        It leaves less mess on your plot and is several times cheaper than ADUs that demand from-the-scratch construction. Prefab ADUs, and vice versa, are units of easy assembly. They are already fabricated, and the only thing you pay for is transportation and installation.

        ADU Housing

        After you’ve learned so much about ADUs, their perks, features, and types, read the reviews and imagined your upcoming ADU design, it’s time to reach out to A+ contractors!

        The best way to withstand a cold spring is to withstand it in a small, warm, cozy house that A+ contractors will fabricate just for you!

      • Frequently Asked Questions

        Will ADU builder contractors assist by getting permits from local authorities?

        Don’t worry! You will not be left alone with difficult-to-understand legal and technical documentation. A+ contractors will take on a significant part of the bureaucratic red tape, turning the process of obtaining permits from painful to easy and inconspicuous, like a mosquito bite.

        How much does it cost to build an ADU?

        Typically, an ADU’s price ranges from $150 to $300 per square foot. However, it may be higher depending on the city, district, and many other factors. Usually, an ADU’s size is about 1000 sq. ft., so a full-sized ADU will cost approximately $150,000–$300,000.

        Can I convert a carriage house into an ADU?

        Yes, you can. This type of loft home is quite popular, provided you make an effort to design it. Typically, the upper floor of such a conversion becomes an apartment with all amenities, and the lower one remains a garage.
