Accessory dwelling unit construction is a response to the problem with affordable housing experienced by many families in Sacramento. In an ADU’s foundation lies practically the same construction techniques used in the construction of a large house, with the caveat that the ADU is a miniature copy.

Many families in Sacramento opt for building an additional living space, such as an in law suite, to provide comfortable accommodation for their relatives in need of constant care.

Be your goal adding square footage to your residential property, providing accommodation for relatives who need care, or creating a new source of financing – ADU builders, A+ Construction & Remodeling, are ready to take on your project!

ADU Builders Rancho Murieta, CA

How can you build a solid but affordable ADU without sacrificing quality? The A+ team consists of builders, engineering specialists, architects, designers, plumbing masters, and professionals in the spheres of flooring, drywall covering, and electrical wiring service. Such a comprehensive group of skilled people can both get your window installed and go through the permitting process.

It all means less time for coordination between professionals from different companies and fewer costs for additional explanations of the tasks, consultations with specialists, and the cost of rework in case of inconsistency in the different masters’ work methods.

Get your residential living space expanded with the help of a reputable ADU building business in Sacramento, California!

ADU Contractor Rancho Murieta, CA

A+ Construction & Remodeling is one of the recognized leading ADU building contractors in the Sacramento area. Among all the other perks an A+ company might offer, the most outstanding are the following:

Unique Design Solutions

One of the key features of building an ADU with an A+ team is creative freedom and deep project involvement. Detailed discussions, constant dialogue, and modern methods of modeling allow homeowners to directly control the design process so that the project becomes as close to their vision as possible.

High Speed and Top-notch Quality

When it comes to such large-scale buildings as ADU, any delay caused by the mistake of a specialist can greatly delay the construction, for example, with the arrival of adverse weather conditions. That’s why we do our job according to the methodology already worked out over the years with trusted suppliers and specialists who know their business. Because the beaten path is always the faster way to go.

Less Environment Impact

When we build an ADU on your property, you take care that the materials and equipment we use do not harm the environment. Besides, A+ has certificates and a great desire to outrun other businesses in terms of the degree of environmental friendliness of our work.

Anti-risk Warranty

A+ Construction & Remodeling has a high rating and many good reviews on Yelp and other websites. Our licenses are validated, and our professionalism is proven by more than 20 years of experience in the construction field.

Smooth Customer Experience

The process of building an accessory dwelling unit is typically bothersome. Therefore, so that it wouldn’t appear to you as such toil, A+ ADU home builders will take over the bulk of the time-consuming project development and realization, leaving the homeowner’s family to make only important decisions.

ADU Contractor Building Types

Among typical ADU projects, general contractors distinguish the following ADU groups:

  1. Detached ADU;
  2. Attached ADU;
  3. Garage Conversion;
  4. Junior ADU.

Tiny home builders recommend the first option if you plan to rent out your ADU. Detached ADUs belong to the more private type of accessory dwelling units, as their structure does not imply a direct connection to the primary residence.

Conversely, attached ADUs are more suitable if you plan to use your accessory dwelling unit for aging relatives who need constant supervision. This type of ADU project is designed in such a way that the accessory building is adjacent to the main one, sharing one of its walls.

In contrast to new construction, a garage, attic, or basement conversion must be transformed from an existing structure. This option is best suited for a family with an unoccupied garage.

If a typical ADU can reach 1000 sq. ft., a junior one should not exceed 500 sq. ft. in maximum size. Junior ADU is subject to fewer California state law restrictions and regulations, as it is only possible as a conversion.

Choose an ADU according to your taste and budget and entrust it to a professional contractor, A+ Construction & Remodeling!

ADU Unit Construction Rancho Murieta

Before you begin to construct an ADU, there are a few state law rules with which every ADU project is obliged to comply.

These are:

  • Both owners of single-family households and multifamily households are entitled to have an accessory dwelling unit (ADU);
  • If a single family lives in the main house, it can have one detached or one attached ADU plus one JADU conversion. It doesn’t; only one ADU is allowed;
  • Multi Family lots may have one ADU for every four existing residential buildings;
  • The minimum ADU size in Sacramento, California, is 150 sq. ft.;
  • The maximum size for an ADU with one bed is 850 sq. ft.;
  • The maximum size for an ADU with two bedrooms is 1000 sq. ft.;
  • The JADU size must not exceed 500 sq. ft.

Benefits of ADU Building

It is the versatility and multi-functionality of ADU projects that have led to their growing popularity in recent years. Accessory dwelling units may be used both as extra space for housing a person or a family and as a business idea.

So, what exactly creates such a great demand for ADUs?

  • An accessory dwelling unit (ADU) is well-suited for life-cost reduction. Some people need only a small house with the necessary amenities to be fully satisfied. As a factor in fulfillment, simplified life conditions lead to a reduced rate for accommodation, no need to move far from loved ones, and no need to spend a lot of time and money on construction.
  • An accessory dwelling unit (ADU) may become a shelter for aging parents in need of care. Given that there are people in your household who can take care of the elderly, housing your aging parents in their granny apartment will be more budget-friendly in the long run than paying a monthly fee for living in a nursing home. And this is not to mention that your relatives will be happier spending time with their loved ones.
  • An accessory dwelling unit (ADU) works well as a place for remote work. Contractors recommend ADU construction if you’re currently in need of secluded space to serve as a home office for your remote work or a workshop. You can pick a small area, such as a 500-foot JADU, in the garage if you don’t have a second car.
  • An accessory dwelling unit (ADU) is a cozy and convenient garden cottage to accommodate guests. Is it difficult to be known as a hospitable owner? Not at all, if you have a separate, equipped mini-cottage on your site for temporary accommodation of guests. Instead of empty garages, it’s much better to have a spare place for visitors from other cities, isn’t it?
  • Accessory dwelling units can be rented out. When building an ADU, it makes sense to look a little forward. The fact is, you can build your annex for one purpose (for example, for guests) but have in mind the prospect of another – to earn additional family budget financing. So renting out an ADU in Sacramento can bring you another monthly income of about $1500–$2000, depending on the ADU size, its style, the attractiveness of the place of residence, distance from city facilities, and so on.
  • Accessory dwelling units increase the total value of the property when it is sold. As another experience shows, the approved financing option works post-repair resale. According to the prices on the market, a new ADU can add from $200,000 to $500,000 to the price of your property.

Thus, there are plenty of reasons to embark on ADU projects. And you can proceed to enjoy all of these advantages in a few months by making a good deal with A+ ADU home builders.

Rancho Murieta ADU Construction Company

When choosing the right ADU construction contractors in Rancho Murieta, Sacramento, an owner more often bases his or her preferences on the presence of the following factors:

  • Locally owned business. Contractors who live and have their offices in California are more familiar with local legislation and have a better network with local suppliers. In addition, they contribute to the development of local communities.
  • Approved and licensed. The opportunity to get acquainted with official documents confirming the abilities and competencies of specialists strongly tips the scales in favor of a potential client choosing a specific contractor.
  • Extensive portfolio and review collection. The evidence is the foundation of trust in the contractor. That is why the gallery of complete ADU projects and the lively opinions of people about the service range provided help to construct and maintain the image of the business.
  • Prices that are competitive in the local market. A professional proofreader knows from whom to buy cheaper and from whom the quality of materials is better. That is why the policy of fair prices demonstrates the experience and ability of the contractor to pursue their interests without neglecting the interests of the client.

All of the aforementioned are things A+ Construction & Remodeling is capable of offering. Contact an A+ contractor to get both a competently complete job and customer-oriented service.

Building an ADU in Rancho Murieta

The preliminary stage of the accessory dwelling unit’s construction is the stage at which the owner has the most influence on the final result. For the most productive cooperation, A+ contractors have developed a universal scheme of action:

Initial consultation

To lay the foundation, we need to start by discussing your expectations in general. You get to know us as a contractor, and we, in turn, form an idea of the work ahead.

On-site check and free estimates

A+ contractors will do research to estimate the costs particular to your location: zoning and architectural restrictions, ADU height and size requirements, building permit fees, etc.

Developing a floor plan and design solution

Whether it’s your own accessory dwelling unit plan, a standard plan, or a custom one, at this stage, our specialists will bring it to perfection. Here you can choose both general details of the new construction, like which windows and roof my home will have, and small details, like the materials for kitchen cabinets.

Agreement between the contractor and the client

After clarifying all the details, including the amount to be paid, the A+ team prepares a contract that includes the scope of work that the contractor undertakes to perform down to the smallest details. If you do not have sufficient financing at the moment, we will help you find a suitable lender. Besides, at the same stage, our employees begin the process of obtaining building permits.

Engineering and start of construction

With the building drawings, the configuration of the plumbing system, wiring, and other infrastructure of the future unit, the construction phase begins. Throughout the entire construction process and preparation for it, A+ contractor employees are ready to answer any questions that arise any day of the week.

Prefab ADU Construction

If your estimate shows that your family budget cannot afford a custom accessory dwelling unit (ADU), A+ contractors suggest paying attention to a more budget-friendly option: a prefabricated ADU. Manufactured according to the standard plan directly at the factory, they are significantly less expensive. Since the development of an individual plan is not required in this case, the only thing left to do is to install them.

Buy a high-quality, stylish modular ADU for your yard at a price several times less than for an individual project, and move into it in the shortest possible time!

ADU Housing

Quality housing in the Sacramento region of California became affordable for homeowners with various accessory dwelling unit (ADU) options at their disposal! After this extensive review, you’ve learned a lot about ADUs, their types, purposes, and perks. It remains only to come up with your own plan.

And then contact an A+ contractor to build the miniature home of your dreams!

  • Frequently Asked Questions

    Which ADU type is better to choose for an adult child?

    Building an accessory dwelling unit (ADU) gives you a great chance not to part with grown-up kids too soon if they study in the same city. However, at this age, they demand their own private space. Taking this into account, ADU contractors may recommend a detached ADU with its own entrance. Live close, but leave a respectful space between you and your family member.

    Can I arrange an accessory dwelling unit (ADU) on the second floor of my garage?

    Yes, this is a common type of garage conversion. With the help of A+ professionals, you can easily transform your unused garage space into a fully functional, nice loft studio. More so, if you see potential in any of the premises already available in your house (for example, an old, cluttered attic or basement), you can turn them at least into a cozy place where you can live and, at most, into a source of income.

    What is the difference between a home addition and an accessory dwelling unit (ADU)?

    An ADU unit is a full-scale home with effective kitchen space, a bathroom, and a bedroom. A home addition, even if it is a room addition or a floor addition, is an extension of an already existing home; it is an integral but not an independent part of it. An ADU can generally stand apart from the house and not intersect with it in any way. The only connection between them will be the site on which both structures are located.
