Why Fresno Homeowners Choose Our ADU Builds

Building an Accessory Dwelling Unit in Fresno needs a good understanding of local rules, how to build things strong, and what the Fresno weather is like. We focus on building methods that last a long time. This includes properly compacting the sub-bases for foundations. This helps stop settling in Fresno's expansive clay soils. It means your ADU will stand strong for many decades.

Our process starts with a full site assessment. We look at the existing utilities and the property lines. After this, we do precise architectural planning to get the most usable space and natural light into the ADU. We pick materials that work well for Fresno's hot summers. This includes high-R-value insulation and cool roofing options. This makes sure the ADU is energy efficient and comfortable for people in Fresno.

Frequently Asked Questions

An ADU project in Fresno typically takes 6 to 10 months from when we start the design work until the final inspection is complete. This ADU project timeline includes 2 to 4 months for the design and the permitting process with the City of Fresno's Development Department. After permits are approved, the construction phase for an ADU project usually takes 4 to 6 months. Things like how complex the site is, how easy it is to connect utilities, and how long it takes for materials to arrive can change the total time for the ADU project. Integrity ADU works to keep the project moving forward efficiently at every stage for homeowners in Fresno.
In Fresno, California, the maximum size for an attached Accessory Dwelling Unit (ADU) is 50% of the main house's living area. This attached ADU size is limited to 1,200 square feet. For detached ADUs in Fresno, the maximum size is generally 1,200 square feet. This detached ADU size limit applies no matter the size of your primary home. There are also minimum size requirements for ADUs in Fresno, which are usually 150 square feet. Specific setback rules from property lines and existing structures must also be followed for ADU compliance in Fresno. Integrity ADU understands these ADU regulations for Fresno homeowners.
Yes, an ADU in Fresno will require independent utility connections for water, sewer, and electricity. Sometimes, approved sub-metering from the primary residence is an option. Integrity ADU assesses your existing infrastructure during the initial site visit. This assessment helps us determine the most cost-effective and compliant method for your ADU utility hookups. This work often involves trenching for new utility lines or upgrading existing electrical panels. We make sure your ADU meets all local code requirements for independent living in Fresno. Integrity ADU handles ADU utility connections in Fresno, CA.
For ADUs in Fresno, a reinforced concrete slab-on-grade foundation is commonly used. This type of ADU foundation is cost-effective. It also works well for the expansive clay soils we have in the Fresno area. Proper soil compaction is important for these ADU foundations. A vapor barrier is also important to stop moisture from getting in and to prevent potential heaving of the ADU foundation. In some situations, a raised foundation with a crawl space might be a better choice for an ADU. This is especially true on sloped lots or when specific engineering plans say it is needed. A raised ADU foundation offers easier access for future utility work under the ADU. Integrity ADU builds solid ADU foundations for Fresno homes.
ADUs in Fresno must follow California's Title 24 energy efficiency standards. These standards are some of the strictest in the country. This means there are specific rules for insulation in walls, ceilings, and floors. For example, walls often need R-19 insulation, and ceilings generally need R-38 insulation. Windows also have to meet high-performance ratings, like a U-factor of 0.30 or lower, which shows how well a window keeps heat in. HVAC systems must also be efficient. Integrity ADU designs our ADUs in Fresno with these Title 24 standards in mind. We often include things like cool roofs and energy-efficient appliances. This helps to keep utility costs down for the people living in the ADU. For Fresno homes, Integrity ADU is here for all your ADU construction needs.
