      Our Process



      Schedule a Virtual or an In-House Consultation with our Remodeling Consultants to discuss the scope of your project. Answer a few questions about your construction goals so we can start working on an estimate.



      Come in for an appointment to our Designer Showroom. We will go over our detailed estimate, make any adjustments, review the designs, talk about our process and take a look at the materials.



      We sign a contract and get the ball rolling. You will meet with our Designer to finalize the designs. In the meantime, our experienced team will take care of the permit process and all the legal paperwork.



      We incorporate digital technologies into our construction processes to be more efficient. You will receive regular updates from our production team in a personal chat, and will be able to ask any questions at any time.



      Work with our designer in creating
      a home of your dreams.


      Our team will prepare 3D renderings and bring your project to life.

      UP TO CODE

      We will make sure your home is up to code and compliant to all building laws.


      Our engineers will prepare permit-ready plans for your project.


      Let our designer help with selection of materials specifically for your design.


      Our experts will have all the permits needed to get your project started.
      How long would it take to build an ADU?
      Usually, the entire process of designing, permitting, and building a custom ADU will take 4-6 months of preparation and 6-9 months for construction. Some counties have pre-approved ADU standard plans (PRADU), so with pre-approved plans the permitting time is cut down to just 2 months.
      How much does it cost to build an ADU?
      The cost depends on many factors such as your house/site conditions, type, style and size of the addition, which finishing materials you decide to use, etc. Our main goal is not only to deliver the best construction product but to keep the entire process clear and understandable for you from start to finish. After the initial meeting, we will provide you with a preliminary estimate and will work with you to connect it to your budget. As a design-build company, we will take care of all the steps — from design and blueprints to construction, inspections, and everything in between. A dedicated project manager will be with you during the entire project to help you and answer all your questions!
      What are the payment terms?
      We create an individual payment schedule for each client. You can pay by cash, credit card, bank transfer, or check. You have the option to pay online, by mail or in-person. We can also work with any financing institution of your choice, if you're financing your project.
      Is an attached addition more expensive than a detached one?
      That would depend on the condition or the existing structure we are adding on to. Sometimes there are things that need to be addressed with your existing structure in order to be able to add on to it, in which case building a detached structure would be less in cost.
      How big can an ADU be?
      Depending on the county you live in but anywhere from 800SF to 1200 of livable space. Other spaces such as a garage or sunroom can be added in addition to those square footages.

        A+ Construction & Remodeling designed and built an addition to our home. The work was timely and excellent, and we didn’t have to worry about anything from the very beginning. The staff was friendly and helpful. Most importantly, the addition looks like it has always been there. Highly recommend.

        I decided to build my parents an addition so they live next to us. If you are looking for a company that strives to provide excellent quality and workmanship this is as good as it gets. They work hard to keep the customer happy. My folks cannot be more pleased with their new home. And I couldn’t be more pleased with communication and amount of attention to detail.

        We came to A+ Construction looking to have an addition built for our daughter. They prepared a beautiful rendering of the new place and we immediately got over-the-top excited about this project. The execution didn’t disappoint. The crew worked really hard!

          ADU Building Reasons

          In the past few years, ADUs have become widely popular across the country and more so in California due to the rising housing crisis that the state is facing. The state has made it easier, than ever before, to build an ADU on your property with the reduced zoning laws and many residents are taking advantage of that for themselves and their loved ones. Read below as we break down the basic information that we felt would be important for you to know if you’re considering building an ADU on your property.

          There are many reasons to build an ADU on your property and the answer will likely be unique to you and your family based on your situation.
          Below are some of the most common reasons why people choose to build an ADU.


          If you love hosting guests at your house but don’t want guests to disrupt your lifestyle, having a small ADU on the property for your guests to stay in might be the best solution. Whether you have someone stay a week or a few months, you can continue living the same lifestyle while having guests right next door.

          Additional Income

          Having an ADU on your property will allow you to rent it out to long-term tenants or short-term tenants for an additional income that would not only pay for the ADU in very little time but also help alleviate mortgage expenses of your main house. An ADU can easily become passive income with minimal effort. There are many options to have more privacy added to your property if this is the reason you’re looking to build an ADU.

          Living Quarters

          Whether you want to have your elderly parents live next to you so you can take care of them or having your teenage kids live next to while having a space of their own, having an ADU can you give you just that and more. With housing costs, we are seeing more family members choosing to live under the same roof. Having an ADU on your property can make those living arrangements a lot more comfortable for you and your family members.

          Additional Space

          If you work remotely, have a hobby or a business or simply want a man-cave on your property, an ADU is a great solution that will allow you to have that space you need to focus and get things done without distractions. This multi-purpose space can easily be customizable to give you the space that functions for your needs.

          ADU Building Sacramento Area Regulations

          Quantity of ADUs Per Lot and the ADU Size
          The Sacramento State Law permits the city residents to have two ADUs within one primary dwelling lot. The total lot coverage of the ADUs (or a single-unit dwelling) must not be more than 1 200 square feet. But the
          residents of the City of Sacramento must also pay attention to the primary lot itself. According to the City of Sacramento’s manual (ordinance), the lot size must be at least 5.200 square feet. Any lot sized over 10 000
          square feet can feature a 600-square-feet ADU. On the smaller-sized lots, the building of an ADU is prohibited. All ADUs must equally follow height requirements and do not exceed 14 feet in their height.
          ADU Design
          All designers in this field recommend making an accessory dwelling unit architecturally compatible with the primary residence unit and the surrounding neighborhood. The colors, materials, and other features of your new
          ADU must be compatible with those of your primary dwelling unit and meet the local law requirements. Otherwise, the construction of an ADU will be prohibited. Every part of an ADU unit’s balcony or open-stair landing
          facing the rear lot’s line (or the side lot line nearest to the accessory dwelling unit ADU) must be placed at least three feet above the ground level. Using appropriate designs such as “no step” entrances is preferable
          where topography and site constraints allow. It’s also crucial to meet zoning designation and setback requirements to building accessory dwelling units. The ADUs front yard and street side yard setbacks must comply with
          the property’s zoning requirements.
          Fire Safety

          You don’t need to meet fire sprinkler requirements in the following cases:— As to detached ADUs: the main unit has a sprinkler; your ADU size is no bigger than 1.200square feet.

          — Regarding the attached ADUs: the main unit has no sprinkler. The ADU size is no more than half the primary unit’s size; the total size of the structure (with the ADU included) is no more than 3.6 square feet.

          Sacramento Setback Requirements
          It is essential to build ADUs at a certain distance to the primary dwelling unit, depending on the zone in which your property is located. Conversions (i.e., a garage on the property line) do not need to meet
          setback requirements. But an additional multi-story property must fit the requirements.An ADU with one story doesn’t need to meet side yard and rear yard setback requirements. It must be at least 60-feet from the front property line or comply with two-story ADU setbacks. A two-story additional building
          must be a 4-foot side yard and rear yard setback. The ADUs front yard and street side yard setbacks must comply with the property’s zone requirements.
          Parking Requirements
          No parking zones are required for an ADU in Sacramento.

          ADU Construction Sacramento

          All in all, the benefits homeowners can get by buying themselves a mother-in-law house are many. All decisions to have one built made, but how and, moreover, who to ask for professional ADU construction services? Read on to
          find out about the best approach to picking a professional to build an ADU with all things considered.

          The choice of the Right ADU Design/Build Specialist
          Be ready for quite a splurge if your major is a decent ADU design and construction. While some manufacturers have put up some incredibly high price tags, others still manage to keep the prices at their lowest and provide
          quality services at reasonable costs. On the one hand, the planning and construction themselves are already tough tasks to fulfill, the other side— the legal one— is a huge space to cover up, and the assistance of some
          shrewd and hence, well-paid attorney specialist would be most required. The statistic shows that it is the deficiency of knowledge regarding the actual laws and regulations is the formative factor in the most delays and
          other issues arising during the ADU construction process.The experience of our team doesn’t need bragging about to be noticed: we’ve been around for nearly a quarter of a century, so we have acquired sufficient knowledge and built up a certain amount of skill that we
          perpetually develop through continuous training and courses for employees. Besides general home and kitchen renovations and constructions, we specialize in designing and building ADUs. In other words, the entire process,
          from design outlines, assembly, up to finishing off, is to be performed under our thorough supervision through the assistance of our certified professionals.Choosing a pro is first off, but there’s more to the ADU building process if you want to make it right, with proper respect to laws and touch if individuality in both interior and exterior design. Let us consider
          the requirements set for ADU builders and future owners.
          Style, shapes, and textures

          The first thing to consider is fitting the environment. Namely, your newly-built structure should not stand out among the rest buildings in close vicinity.

            • The design and color schemes matter a lot, too. Some homeowners try to make their tiny houses look exactly like those of their neighbors. What also matters is the common design of entrances that should be
              conformed to by all neighbors.
            • Another important thing is the heights of the building, which, too, should not stand out among other houses in the neighborhood. The maximum height is 14 feet, grade-to-plate. The main dwelling unit,
              understandably, should be taller.
            • As to selling the ADU, you cannot do it without selling the primary dwelling. However, ADUs are more than often rented out^ as one of the benefits for owners.
            • That you can wish to live in or rent out an ADU, it should be connected to the major utilities, including sewers, water (in RD zones), and electricity.
            • Based on location, the fees to be paid for building an ADU differ. You can find more on the subject by addressing
            • Some historically important sites can be used for the construction of an ADU; however, their regulations for such zones are peculiar. Site plan design and thorough review of design is mandatory under chapter
            • As to the entry requirements, there can be no passages between the main unit and an ADU.

          If your single unit comprises an ADU, you can perform conversion of the existing building. Mind that the ADUs situated in historic areas may be subject to different requirements. An ADU should have a separate entrance
          and be built in line with fire safety demands.

              • The stats show that, on average, an ADU brings to their owners-renters around $19 000 annually.

          As to the contractor company, the choice of one should be weighted and based on certain factors. Read on to find out what qualities should a proper general contractor have to ensure lawful and successful ADU

          What qualities should Sacramento ADU contractors have?

          The rising popularity of ADUs in Sacramento has set new objectives for construction and remodeling companies. The situation is fueled up by the world’s pandemic, which brings in new struggles and raises up new quality and
          safety standards. While the rental costs are hovering, the benefits from renting out an ADU is a good long-term investment. But keep in mind that a lot depends on the contractor.


          Opt for the contractors that have remained in the industry for a long time. This is usually the right choice, for the experience of the contractor company and its ability to stay afloat in hard times is a clear
          demonstration of the proper approach to business. If your contractor has been around in your area for a while, he knows which strings to pull in terms of effortless supply and high-quality materials.

          Actual knowledge of local regulations

          If you want your ADU to heed the law requirements, your contractor should take up this responsibility. They should be well aware of the actual versions of the local codes, permit regulations, and other legal issues to
          ensure a safe and secure project from the very start of works.

          Well-weighted plan

          While it is quite a challenge to design and construct the ADU, a decent contractor will have a solid, well-designed plan of the construction, with all other important factors considered, beforehand and be able to answer
          all your questions concerning the process.

          Clear communication

          The openness of the contractor is another factor in the basis of the decent construction process. It helps establish the right mood and connection between the property owner and construction specialists. Set all
          hesitation aside and be free to make inquiries.

          Happy client review

          And, maybe, word of mouth, which is still on point concerning the truthful descriptions of services, is to be considered. Your neighbors may have used the services of a certain contractor, so they can recommend a perfect
          one. Besides, there are testimonials on official websites of the best contractors in the sphere.

          Prefab ADU Cost

          If you are wondering whether to build a new additional dwelling unit or to purchase a prefab one, the main distinction worth noticing between the two options is the price. Understandably, the process of designing, outlining,
          and building of an ADU is more time—and money—consuming than, say, opting for the prefabricated type. The prices for the brand new ones register at nearly $128000.

          Contrary to these, the price tags for the prefab dwelling units are way lower, starting at around $30000. However, the construction & utility connections aren’t covered by the amount. Another important thing is the
          acquisition of the permits. What also matters is the legal side of the process, which should be immaculately taken care of.

          What other factors impact the cost of an ADU?

          The first article of expenses is, of course, getting in touch with a knowledgeable contractor. The fee for such services usually amounts to about 10% of the total budget. All consultations, including those concerning
          utility connections, planning, permitting, and regulations, will require a paid specialist’s involvement.

          Turnkey ADU Benefits

          Besides the monetary benefits, prefab ADUs have a lot more to offer:

          • Your primary dwelling unit remains intact and undisturbed because all the construction takes place away from your household. This ensures the usual order of things at your home. However, some preparations and offline
            meetings with your contractor will be required before the start of the operation.
          • While some people overlook the quality and sustainability of prefab constructions, the proper contractors apply only the best materials and tools.
          • Conventional construction procedures can be time-consuming and producing a lot of discomfort to the homeowners, with all that waste and noise during the entire process. This is never the case with the prefab ADUs.
          • Ass the prefab units are fully built off-site, that keeps the peace of your household intact, and the environment is taken care of, too. You can opt for the customized ADU design options to embrace sustainability and
            increase individuality.
          • The functionality of an ADU can be no less developed than that of your primary house unit.

          Other ADU benefits

          Among others, let us consider some more factors making the ADU building an intelligent and economical step.

          • First off, the occupancy of your household increases
          • Second of all, you can rent an ADU out for a good price to enlarge your annual income
          • Third of all, this is a budget-friendly option, compared to the building of a primary dwelling unit
          • Some ADUs can be manufactured with the 3D printing technology involved, which, together with the notch-carving materials and some in-built kitchen equipment used, makes an ADU a seducing option.
          • All things are considered beforehand in the course of a detailed discussion between the contractor and the customer. All the documents required go in, too.
          • The accessory dwelling unit adds value to your household, let alone the monthly income possible through renting out the unit.

          ADU Kitchen ideas

          When you rent out an ADU or let your relatives/friends stay for a couple of nights, it is more convenient than not if the ADU has some kitchen-like features.

          • Therefore, the design of a dining area should be well-thought-out. The best approach is making the kitchen space that can be used for activities other than just eating.
          • Applying a tiny kitchenette or small cabinetry will not make matters worse anyways. The ergonomy is key to a comfortable ADU: built-in appliances and smart storage areas are the way to go.
          • Another important aspect is illumination. The light ought to be close to the natural to provide the best opportunities for working and living, and eating in the ADU. The kitchen area must have a sufficient number of
            electrical outlets.
          • Little things like teapots and coffee makers are a good addition to any kitchen.

          Find reliable professionals

          Most importantly, the work on designing and building your ADU— prefab or not— should be entrusted to the right contractor company having the professional and certified workers in their employ. This will ensure the entire
          process, from outlining the plan up to giving the final touch to the construction at the end, goes well and meets all the federal and local requirements.

          If your aim is to have an extra area within your household where you can chill out, work, welcome guests, or renting it out, deciding on the building of an ADU is the right choice. Our company ensures that all the work we
          take up is done in line with all demands, and we guarantee the utmost success of the operation.
