        Accessory dwelling units, or ADUs, have recently gained a lot of popularity in California. What’s an ADU, and why do hundreds of people consider building it on their property? Shortly, it’s a little additional house with all the modern conveniences that’s suitable for various purposes. For instance, it can serve as an art studio, a guesthouse, a home for grandparents, or just a place to have fun and relax. If you’re considering building an ADU in California, it’s essential to find a reliable ADU builder Sacramento who can help you bring your vision to life.

        ADU Builders Carnelian Bay, CA

        Constructing an Accessory dwelling unit in your own backyard may seem easy and even exciting, but in reality, it’s rather hard. Also, if you lack the necessary skills, you’ll probably make very grave mistakes that will make the whole process way more difficult and expensive and even lead to the house’s demolition. To avoid this, you’ll need hired specialists who will do everything as it should be — or at least assist you.

        ADU Contractor Carnelian Bay, CA

        Selecting the best building company near Lake Tahoe can become the simplest part of constructing the ADU of your dreams.

        But only in case, you pay attention to the next things:

        1. How available is the license? Unfortunately, not every homeowner takes it into account. To construct an ADU, you’ll need to not only ensure that the license and the permit are available but also find out their expiration date;
        2. Customer reviews. In addition to reading them, you can also talk to your acquaintances who have an ADU construction already built on their property. They’ll share their experience with you and inform you about all the pros and cons;
        3. Photos of the contractor’s previous works. Many companies have portfolios with lots of photos on their websites. They’ll help you estimate whether the company suits you or not.

        In any Placer County city, many general contractors fail at one or more of those points. But there’s a company that definitely complies with every single one of them – A+ Construction & Remodeling. It has a large work experience from different places – Olympic Valley, Tahoe City, Auburn, and many others.

        This article will be useful for everybody interested in getting an ADU and searching for the right building company in Placer County near Lake Tahoe. Here, we’ll tell you the main information regarding ADU construction, the main types and advantages of these buildings, and give some advice on how to choose the best general contractor for you.

        ADU Contractor Building Types

        There are a lot of ADU types that can be built on your property. Let’s look at them a bit closer.

        Detached ADU

        Detached accessory dwelling units are often called granny flats since they’re often built for elderly family members. Such constructions are situated separately from the main residence, but they have everything that’s necessary for a decent life. Moreover, it’s possible to rent a detached ADU out for extra income.

        Attached ADU

        Unlike the previous type, an attached ADU is connected to the main home. For example, it may share a common wall, flooring, or a foundation with it. In some cases, there’s even a door between these two buildings.

        Junior ADU

        A junior accessory dwelling unit, or JADU, is a typical ADU with one major difference — its size is much smaller. A junior ADU is a great variant for people who would like to get an ADU but don’t possess the necessary amount of space for a regular one.

        Pool House

        Such an ADU is the best variant for people who like to relax and party with their friends. It’s a rather large house in a backyard with one bedroom and a terrace with an end leading to the pool. Also, this ADU type has a little patio for barbecues and a small territory for various sports games. Pool house-type ADUs have lots of design variants, which is their biggest advantage.

        Converted garage

        There are many variants for using up an already-built garage instead of demolition. For instance, you can turn it into a mini gym, a place designed to engage in your hobbies, an extra room for your friends, and so on. A garage converted into an ADU with a large additional bedroom can make the value of your property significantly higher.

        Above garage conversion

        This is the least-known type of ADU. Basically, it’s a cabin situated over the garage. It can be a small home cinema, a workplace for a freelancer, or a room for your grown-up kid who needs a private space.

        None of the ADU types is worse than the other – every one of them has its own advantages. But to get an awesome ADU that will be really designed for your needs, you’ll have to find a company that will ensure its top-notch quality.

        ADU Unit Construction Carnelian Bay

        In Placer County, any ADU home should be built according to all the norms and regulations of this region. This means that it’s obligatory to consult with an expert lawyer. If you aren’t a specialist in the legal sphere, you may be unaware of some important nuances and details.

        Building an ADU usually consists of the next steps:

        • A consultation with your contractor about the project;
        • Designing the outer and the inner house parts;
        • Creating the construction plan while taking into account all the building rules of Carnelian Bay. Also, you’ll need to estimate the price;
        • Getting required permits and the local authorities’ approval;
        • Constructing the ADU;
        • Making various important things such as utility systems’ connections;
        • The final step is the design of the freshly-built ADU’s inner part — for example, laying a carpet and painting the walls. On this date, the work is done.

        There are lots of great, experienced lawyers who have the ability to help you in getting all the documents, plan the building process, and understand all the necessary regulations of Placer County.

        Benefits of ADU Building

        We’ve already said that an ADU home is quite an inexpensive variant, but the price isn’t it’s only advantage. There are much more, and some of them we’ll list below.

        Accessory dwelling units are so great because of the following:

        1. Passive income from renting out. Usually, such construction has everything that is required for a normal life, so they can be rented out, compensating for all the construction expenses in a very short period;
        2. An accessory dwelling unit will help you communicate more with your family members. After all, it’s an entire extra home where the whole family can gather and have fun;
        3. An ADU makes your property more valuable since it’s a great upgrade of your territory;
        4. An ADU means much better conditions for living. Oftentimes an ordinary home isn’t enough for different tasks such as storing large items. An ADU can be a great solution to this problem, since it adds space that can be provided for a wide range of various things;

        It all means that ADU construction will change your living space, making it much better than before. But to create a really amazing, top-quality, and well-designed ADU, you’ll need an incredibly professional and experienced general contractor — such as A+ Construction remodeling.

        Carnelian Bay ADU Construction Company

        To get an ideal accessory dwelling unit in Placer County near Lake Tahoe, you need to have a very detailed talk with your contractor. Sadly, many general contractor companies don’t give their clients such a possibility.

        In A+, we’re sure that such a policy is completely wrong. Our approach is drastically different:

        • Fruitful negotiations at the beginning. When you meet our team for the first time, you’ll be able to discuss every aspect of future construction and get important tips about it. Also, our specialists will solve all the legal issues, obtain permits, etc.
        • Individual consulting. In case you want to change something in the design or construction plan, you may ask the profile expert everything about it;
        • Editing. If the expert thinks that your idea is beneficial, then the hired construction team will gladly fulfill it.

        The professionals of A+ construction & remodeling company are not only highly-skilled and competent, but also eager to respond to your wishes and do everything as you request.

        ADU Building Carnelian Bay

        People who live in any city of Placer County near Lake Tahoe have to comply with certain rules and regulations when it comes to an ADU building — for example, zoning norms. To get a permit for construction, you need to know and follow them.

        In the list below, you can see only a few examples of such norms:

        1. An ADU cannot be built higher than 1 200 ft;
        2. To create an ADU home of almost any type, either detached or attached, you’ll need parking requirements. The only exception is a garage conversion;
        3. For your main home, owner occupancy is necessary;
        4. One family cannot have more than one ADU and one junior ADU;
        5. You’ll need setbacks of a minimum of 4 feet from any street or driveway, property lines, and buildings;
        6. And a lot more.

        Following all these rules can be rather difficult. But our professionals will develop a construction plan according to every single one of them because they’re real experts in this field and know every detail of it.

        Prefab ADU construction

        If you’re afraid that the building process will be long and make lots of noise, there’s an easier, quicker, and much more comfortable alternative – a prefabricated, or simply prefab, ADU.

        Different parts of these ADUs, such as a roof, flooring, windows, and walls, are produced in advance, then put together on your territory. This variant is ideal for households with single or multiple families who need an inexpensive ADU as soon as possible. Prefab ADUs are usually not very big, but they’re very durable and easily resist harsh weather conditions. It makes them a great place to hide during a thunderstorm, a hail, or a heavy wind.

        ADU Housing

        A small additional home is an amazing long-term investment that will make the price of your whole property way higher and give you the possibility to use your territory much more efficiently. Such a building will give you and your family a much better quality of life and more convenient living conditions.
