ADU costs vary based on size, type, site conditions, and finish level. A garage conversion typically starts in the range of $100,000 to $150,000, while a detached new-build ADU generally falls between $150,000 and $350,000 or more depending on square footage and specifications. We provide detailed cost estimates during the pre-construction phase so you have a clear picture of the total investment before committing. Every project is different, and we recommend a consultation to discuss your specific property and goals.
The timeline depends on the type of ADU and local permitting timelines. A garage conversion might take 3 to 4 months of construction time, while a detached new-build ADU typically takes 5 to 7 months. Permit approval can add 4 to 12 weeks depending on the jurisdiction. We develop a detailed project schedule during the planning phase and keep you updated on progress throughout construction.
In most California jurisdictions, permits are required when the work involves changes to plumbing, electrical, or structural elements. A cosmetic update like painting or new hardware may not require a permit, but moving a wall, rerouting plumbing, or adding circuits typically does. We handle all permit applications and inspections as part of our scope so you do not have to navigate the building department on your own.
Every remodel starts with a consultation to understand your goals, assess existing conditions, and discuss budget. From there, we develop a detailed scope of work, finalize design selections, and submit for permits if required. Once permits are approved, we schedule the work in a logical sequence: demolition, rough-in trades (plumbing, electrical, HVAC), inspections, insulation, drywall, finishes, fixtures, and final cleanup. We provide regular updates and a clear schedule so you know what to expect each week.
SB-721 is a California law that requires periodic inspections of exterior elevated elements, such as balconies, decks, stairways, and walkways, on buildings with three or more multifamily dwelling units that contain wood or wood-based structural components. The law is intended to help identify and address potential safety issues. If your building meets these criteria, inspections are required on a recurring basis. We recommend consulting with qualified legal counsel to confirm your specific obligations. Most Built Construction LLC provides both SB-721 inspections, performed by an ASHI Certified Inspector, and any subsequent repair work needed to address findings.
We offer a complimentary initial consultation to discuss your project, understand your goals, and provide general guidance on scope and budget range. For detailed written estimates that include itemized costs, material specifications, and a project schedule, we conduct a thorough evaluation of the property and scope. This level of detail requires time and expertise, and we are transparent about that process from the start.

Construction consulting is a service for property owners and investors who need professional guidance without hiring a general contractor for a full build. Common situations include evaluating the renovation cost of a property before purchasing it, reviewing contractor bids for accuracy and completeness, auditing a project that has gone off track, or getting a second opinion on a scope of work. We provide honest, practical assessments based on real construction experience.
Thorough pre-construction planning is our primary tool for minimizing surprises. When unforeseen conditions arise, such as hidden water damage or outdated wiring discovered during demolition, we document the issue, present options with costs, and get your approval before proceeding. No work outside the original scope is performed without a written change order that you have reviewed and approved. We believe budget transparency builds trust.
In many cases, yes. The feasibility depends on the scope of work and which areas of the home are affected. For a kitchen remodel, you may need to set up a temporary kitchen in another room. For a whole-home renovation, it is often more practical to relocate temporarily. We discuss this during the planning phase and schedule the work to minimize disruption when staying in the home is the plan.
The first step is to reach out by phone or through our contact form to schedule a consultation. During that initial conversation, we will discuss your project goals, timeline, and budget expectations. From there, we can schedule a site visit if needed and begin developing a scope of work and estimate. There is no obligation, and we will give you a clear picture of what the process looks like before you commit to anything.
