ADU Construction Contractor
We build ADU's in Dixon, California

An Accessory Dwelling Unit (ADU) is a secondary residential unit that can be established on a property with an existing single-family dwelling. These units, often referred to as "in-law suites" or "carriage houses" or "laneway suites" can be either attached to the primary residence or built as detached structures. ADUs provide an additional source of housing, especially in areas like Contra Costa County and Solano County, California, where housing demand is rapidly increasing due to population growth.

These units are typically used to accommodate extended family members or to generate rental income for homeowners, thus contributing to housing affordability in the region.

ADUs in Contra Costa County and Solano County can vary in size but are generally smaller than the primary residence on the property. According to Contra Costa County and Solano County regulations, the maximum size of an ADU is 50% of the primary residence's floor area. This size limitation ensures that ADUs remain secondary to the main dwelling and maintain the character of the neighborhood. ADUs can be designed as stand-alone structures or integrated into the existing residence, such as a basement or attic conversion.

Contra Costa County and Solano County has specific regulations governing the construction of ADUs to ensure they comply with zoning and building requirements. The construction of an ADU must adhere to the underlying zoning district's setbacks and height limitations. Additionally, each property can only have one ADU.  The property owner is not required to reside in either the primary residence or the ADU.  Making them an attractive option for rental income.

What Are The Basic Requirements To Build An ADU?

The demand for Accessory Dwelling Units (ADUs) in Contra Costa County and Solano County, California, has been on the rise in recent years, primarily due to our area's rapid population growth and housing affordability challenges. As a response, Contra Costa County and Solano County officials have established a basic checklist for homeowners interested in constructing ADUs on their property.

Determine if Your Property is Eligible for an ADU

Before embarking on an ADU construction project, it's crucial to determine if your property is eligible. To qualify, the property must be zoned for single-family residential use, and the owner must reside in either the primary dwelling or the ADU.

Understand the Size and Design Requirements

Contra Costa County and Solano County has specific size and design requirements for ADUs to ensure they blend seamlessly into the neighborhood. ADUs cannot exceed 50% of the primary dwelling's floor area.  For example, if your primary residence is 2500 square feet, your ADU could not exceed 1250 square feet in size.  Additionally, the design must adhere to the underlying zoning district's setbacks and height limitations.

Obtain Necessary Permits

Before beginning construction, homeowners must obtain the necessary permits from the Contra Costa County and Solano County Planning Department. This process involves submitting a completed application, including a site plan, floor plan, and elevation drawings. The department will review these documents to ensure compliance with zoning and building requirements.  At Saitta Construction we can provide drawings and handle the permitting process for you.

Adhere to Building Code Requirements

ADUs must be constructed according to the California State Building Code. This means meeting requirements for fire separation, emergency egress, and other safety standards. At Saitta Construction we are well-versed on these requirements and can ensure your new ADU complies with these regulations.

Plan for Adequate Parking

Contra Costa County and Solano County regulations require at least one off-street parking space for each ADU. The space must be located on the same property as the ADU and cannot obstruct access to the primary dwelling. This requirement helps maintain parking availability in the neighborhood.

Consider Utility Connections

Utility connections, such as water, sewer, and electricity, must be planned for during the ADU construction process. Homeowners should consult with their local utility providers to determine the best approach for connecting their ADU to these services.  At Saitta Construction we can also help you with this process.
