Why Fresno Homeowners Choose Our ADU Builds

Building an Accessory Dwelling Unit in Fresno requires a deep understanding of local ordinances, structural engineering, and climate considerations. We focus on durable construction methods, like properly compacted sub-bases for foundations to prevent settling in Fresno's expansive clay soils, which means your ADU stands strong for decades. Our process begins with a thorough site assessment, evaluating existing utilities and property lines, followed by precise architectural planning to maximize usable space and natural light. We specify materials suited for Fresno's hot summers, such as high-R-value insulation and cool roofing options, to ensure energy efficiency and comfort. From navigating city permitting to the final walk-through, we manage every detail with precision. You get a fully permitted, move-in ready ADU built to last, without the guesswork.

Frequently Asked Questions

A standard ADU project in Fresno, from initial design to final inspection, typically takes 6 to 10 months. This includes 2-4 months for design and permitting with the City of Fresno's Development Department, followed by 4-6 months for construction. Factors like site complexity, utility connections, and material lead times can influence the overall duration, but we aim for efficient progression at every stage.
In Fresno, the maximum size for an attached ADU is 50% of the existing primary dwelling's living area, up to 1,200 square feet. For detached ADUs, the maximum size is generally 1,200 square feet, regardless of the primary home's size. There are also minimum size requirements, typically 150 square feet, and specific setback rules from property lines and existing structures that must be observed for compliance.
Yes, an ADU in Fresno will require independent utility connections for water, sewer, and electricity, or approved sub-metering from the primary residence. We assess your existing infrastructure during the initial site visit to determine the most cost-effective and compliant method for utility hookups. This often involves trenching for new lines or upgrading existing panels, ensuring your ADU meets all local code requirements for independent living.
For ADUs in Fresno, a reinforced concrete slab-on-grade foundation is commonly used due to its cost-effectiveness and suitability for our region's expansive clay soils. Proper soil compaction and a vapor barrier are critical to prevent moisture intrusion and potential heaving. In some cases, especially on sloped lots or where specific engineering dictates, a raised foundation with a crawl space might be a better choice, offering easier access for future utility work.
ADUs in Fresno must comply with California's Title 24 energy efficiency standards, which are among the strictest in the nation. This includes specific requirements for wall, ceiling, and floor insulation (e.g., R-19 walls, R-38 ceilings), high-performance windows (e.g., U-factor of 0.30 or lower), and efficient HVAC systems. We design with these standards in mind, often incorporating features like cool roofs and energy-efficient appliances to minimize utility costs for the occupants.
