In recent years, accessory dwelling units have grown in popularity in many American cities, allowing people to improve the existing space and value of the property. The state of California passed a special law in 2020 facilitating the development of this type of building, which you may also know as a “granny unit,” “in-law unit,” “casita,” etc.
The specificities of property, limitations of budget, and the local requirements for building design make each ADU project differ from one another. They might vary in the number and size of bedrooms or living areas and the presence or absence of a kitchen. What is more, you can make a separate apartment out of an old garage or design an extra room with an attached ADU construction, not to mention the possibility of building a full tiny house on your lot.
So if you feel that your Galt, CA house has some existing space that can be turned into a fully functioning property, A+ Construction & Remodeling, an experienced ADU builder, will be happy to provide you with our best services. With lots of experience in building exceptional ADUs, we are more than ready to create one for you as well!
When you and your family become interested in getting a new detached ADU or attached ADU, it is better to contact professionals right away. There are so many details required by the state and city authorities to be included in the project plan that making it all by yourself might cause more issues than use.
In order to formulate your project plan more clearly before discussing it with the experts, it is helpful to know the following facts:
Accessory dwelling units are divided into several types:
The features of the first and second types of ADUs are clear from the titles: in the first case, the structure is located separately from the main house, and in the second case, it adjoins it. However, in both cases, the unit must have a bedroom, living area, toilet, bathroom, kitchen, and separate entrance.
The specifics of junior ADUs are not so obvious. In fact, the junior ADU is different in that its design does not involve a separate bathroom. In addition, ADUs of this kind must be organized in an existing structure and usually are garage conversions.
According to Californian ADU law, the number of ADUs allowed for every single-family home is at least one. Multi-family properties can be extended with one ADU project for every four single-family housings. Even though getting a permit and engineering a new property has become easier, there are still many requirements that one needs to address in order to get approval from the Galt authorities.
Any type of ADU must meet maximum size, design, and maximum height requirements. You are allowed to have 850 square feet for a single-bedroom accessory dwelling unit and up to 1,000 square feet for ADUs with two bedrooms. The best solution would be an ADU designed by a qualified architect, as they properly check for all the regulations to get approval.
When a property owner decides to get an ADU for their single-family or multi-family property, it is important to access the right contractors who value quality and can provide the best results for you.
Last but not least, do a review of all the prices. The final payment should be reasonable, and you should value the quality of projects accordingly. Compare the prices for ADUs between different businesses that often have their ADU projects approved. Luckily, A+ Construction & Remodeling is suitable not only for the price criteria but also for all of the ones mentioned above. From converted garage units to multi-family ADUs, we are ready to create a high-quality project of any type.






The process of constructing an ADU all by yourself is not easy, as you have to consider a lot of specificities of your property and law regulations. Moreover, there is quite a lot of work to do, even for the whole family: you have to design the project, address all of the requirements for your property and receive the permit, do all the engineering and utility connection work, and even more.
A+ Construction & Remodeling team has plenty of experience in building ADUs of different types. We value the quality and safety of our final products, so you can be sure that you will get what you want. Before the project even starts, you receive a free estimate for all of the work required, and you can carefully review it to be according to your budget.
Want to become a lucky owner of a beautiful ADU on your property? Contact the A+ crew now and start the planning right away. You can book your first consultation online or visit us in person to discuss the subject. Whether you want to convert a garage or build a brand-new ADU, we are ready to work on your project!
Every accessory dwelling unit in Galt needs a building permit. Applications are reviewed by the Sacramento County Building Permits & Inspection Division (or your city building department for incorporated areas), which checks your plans against California’s statewide ADU law and the local zoning, building, and fire codes for Sacramento county. As a full design-build contractor, A+ Construction & Remodeling prepares the drawings, structural calculations, and Title 24 energy documents, then submits and manages the permit on your behalf so you don’t have to navigate the counter alone.
Under current California rules, most ADUs are approved ministerially - meaning no public hearing - and the jurisdiction must act on a complete application within 60 days. Key statewide standards that apply in Galt include:
Local factors in Sacramento county - such as septic vs. sewer connections, fire-hazard zones, well water, slope, and utility upgrades - can still affect your design, timeline, and cost. We evaluate these during a free site review and build them into your estimate up front, so your permit moves through the Sacramento County Building Permits & Inspection Division (or your city building department for incorporated areas) without surprises.
