What affects the price
Building an ADU is a major project, and the final bill depends on a few key things. Site prep is a big factor; if your land is sloped or needs extensive utility connections, costs go up. The materials you choose—from siding to kitchen finishes—also change the math significantly. Whether you’re building a detached unit or converting an existing garage shifts the permit requirements and structural work needed. We provide exact pricing confirmed free on the call.
About this service
These companies provide end-to-end management for property owners looking to add a secondary unit. They typically offer a mix of design, permitting, and construction management services to streamline the project. You need to hire a company when you want a structured, professional approach to the entire build process rather than managing individual subcontractors yourself. They help ensure your unit is built to code, on time, and aligned with your budget goals.
