In 1935, in a small European village, Nicholas was born. He developed a passion for construction that he spent years perfecting. Nicholas later passed that knowledge on to his son Edgar. In 1997, Edgar began working in the construction field in Massachusetts. Edgar then passed on all he knew to his son, Roman.
Roman’s humble beginnings in this family-owned business are why he is committed to providing great craftsmanship. He takes pride in the quality of work that the team at A+ Construction & Remodeling has provided for more than 30 years.




ADUs, or accessory dwelling units, have become one of the most popular project types for which general contractors are hired. And honestly, this is not a big surprise because the amount of benefits and functionality that an ADU can bring to a homeowner is truly astonishing. Nowadays, it is possible to create any kind of ADU in Sacramento, CA.
With a small accessory dwelling unit on your property, you get not only extended living space, but also a guest house or a new home to rent out and receive some additional income. The great thing is that you can create a quality ADU with any kind of budget, and A+ Construction & Remodeling team is more than ready to help you with this task. Explore the possibilities of ADU homes Sacramento and transform your property into a versatile and valuable space.
An ADU builder is a licensed design-build contractor who manages the entire process of building an accessory dwelling unit – from architectural plans and permits to full construction.
A+ Construction ADU Builders specializes in ADUs across Sacramento and handles design, engineering, permitting, and construction under one roof. Our team works with local zoning requirements, setback rules, and utility connections to make sure each project meets city and state regulations.
Unlike a general contractor, an ADU specialist understands California-specific requirements such as SB 9, AB 2221, and Title 24 energy compliance, which directly impact how your unit is designed and approved.
ADU construction costs in Sacramento typically range from $180,000 to $320,000 for a new detached unit, depending on size, design, and site conditions.
| ADU Type | Size | Typical Cost |
|---|---|---|
| Studio / 1-bedroom | 400-600 sq ft | $195,000 - $235,000 |
| 2-bedroom ADU | 700-1,000 sq ft | $250,000 - $320,000 |
| Detached ADU (average) | 350-1,000 sq ft | $180,000 - $320,000 |
| Prefab / simplified ADU | - | Starting around $150,000 |
Final pricing depends on several key factors, including site preparation, utility hookup and connection fees, design complexity, and material selections. City requirements and impact fee exemptions may also affect the total cost.
A+ Construction provides detailed, property-specific estimates so you understand exactly what your project will require before moving forward.
Most ADU projects in Sacramento take 6 to 10 months from start to finish, depending on permitting timelines and project complexity.
| Phase | Timeline |
|---|---|
| Feasibility + initial design | 3-6 weeks |
| Plans + engineering | 4-8 weeks |
| Permitting (City of Sacramento) | 2-4 months |
| Construction | 3-4 months |
A+ Construction manages each stage of the process and works directly with local agencies to keep projects moving and minimize delays.
A+ Construction ADU Builders is a licensed design-build contractor specializing in accessory dwelling units throughout Sacramento and surrounding areas. We manage the entire process, including site feasibility analysis, architectural design, permitting, and construction.
Our team works directly with the City of Sacramento and local agencies to prepare complete permit packages, coordinate approvals, and keep projects moving efficiently. During construction, we assign a dedicated project manager who oversees each phase and ensures all work meets approved plans and California building standards.
We provide clear project scopes, realistic construction timelines, and detailed cost estimates so homeowners can make informed decisions before starting their ADU project.
A+ Construction ADU Builders holds a BBB A+ Rating and is an Accredited Business with the Better Business Bureau of Sacramento.
Licensed by the California Contractors State License Board (CSLB #1007869).
A+ Construction designs and builds all major types of accessory dwelling units in Sacramento.
A standalone structure built separately from the main home, offering maximum privacy and flexibility.
An extension of the primary residence that shares at least one wall while maintaining a separate living space.
A conversion of an existing garage into a fully functional living unit, often with lower construction costs.
A smaller unit within the existing home, typically under 500 square feet, designed for efficient use of space.
A+ Construction manages the entire ADU building process, coordinating each stage to ensure compliance with California and local regulations.
The process begins with a site feasibility analysis, where we evaluate zoning, lot size, setbacks, and utility access to determine what can be built on your property.
Next, our design team develops a layout based on your goals, whether you are building for rental income, family use, or additional living space. We then prepare architectural plans, structural calculations, and Title 24 energy documentation required for permit approval.
Once plans are complete, A+ Construction submits the permit package to the City of Sacramento and manages the review process until approval. After permits are issued, our construction team builds your ADU according to approved plans and oversees inspections through project completion.
Building an ADU provides both immediate and long-term benefits for homeowners. Rental income for a one-bedroom ADU in Sacramento typically ranges from $1,400 to $2,400 per month, depending on location and unit size. This can translate into an estimated 8-10% annual rental return, making ADUs one of the most effective ways to generate income from your property.
In addition to income potential, ADUs increase property value, provide flexible living space for family members, and create opportunities for home offices or guest accommodations.
Recent California laws have made building ADUs significantly easier for homeowners.
SB 9 (2021) allows homeowners to build additional units on single-family lots.
AB 2221 (2022) simplifies permitting and reduces approval barriers.
AB 976 (2023) removes owner-occupancy requirements, making ADUs more accessible for rental use.
Local zoning rules, setback requirements, and utility regulations still apply, which is why working with an experienced ADU contractor is essential.

Creating an ADU includes not only the construction process itself but also complying with various law regulations imposed by the city, state, and country. Local rules may vary from one place to another, and that is why knowing all the specificities is important.
Take a look at some of the legal requirements that have to be followed:
An ADU plan that does not comply with these and some other regulations will not be approved by the local officials for the permit, and you will have to pay for another application once it is corrected. To avoid wasting your time and budget, it is better to hire contractors with professional legal staff, such as the ones at A+.
We carefully review each plan at the stages of development to make sure that everything is done in the correct way. Thus, you won’t have to study the numerous laws by yourself or look for a specialist separately. Such a way of building an ADU in Sacramento is more comfortable and convenient for any property owner.
