01 · ADU fundamentals
Understand the terms before applying them to a property
General orientation for common ADU and garage-conversion questions. Property application remains a separate review step.
What is an ADU (accessory dwelling unit)?
An ADU is generally understood as a secondary dwelling associated with a primary residential property. Common forms include detached, attached, conversion, and junior accessory dwelling units; the definition applicable to a specific property requires current official-source review.
What is a garage conversion, and is it different from an ADU?
A garage conversion adapts existing garage space for a different use. Whether a proposed conversion is treated as an ADU, and which requirements apply, depends on current official rules and the property context. Requires official source verification.
Can an ADU fit on my lot?
This page cannot determine that. Property records, zoning, lot conditions, existing improvements, access, utilities, and applicable official requirements must be reviewed for the specific parcel. Requires official source verification.
02 · Planning boundaries
Know which answers require an individual review
Permit, price, and schedule questions are not converted into website promises. They stay attached to evidence and owner review.
Do I need a permit to build an ADU in the Sacramento region?
ADU work commonly involves city or county review, but the process and requirements vary by jurisdiction and project. The applicable path must be confirmed with the appropriate local authority. Requires official source verification.
How much does an ADU cost?
The website does not publish or promise prices. Site conditions, scope, selections, professional inputs, and jurisdiction-related items can materially change an estimate; any future estimate must be prepared from project evidence and approved by the owner before a commitment is made.
How long does an ADU project take?
The website does not publish or promise schedules. Design, review, procurement, site conditions, and construction scope can affect sequencing; any future project plan must be evidence-based and owner-reviewed.
03 · Working model
See how West Coast KBP organizes responsibility
The differentiator is a visible control structure: candidate artifacts, evidence, OwnerReview, bounded action, and a reviewable record.
What areas does West Coast KBP serve?
The public service area is the Sacramento region, including Roseville, Rocklin, Lincoln, Folsom, Granite Bay, El Dorado Hills, Citrus Heights, and nearby areas.
How is West Coast KBP different from a typical contractor?
West Coast KBP is building a controlled operating model around visible scope, state, approvals, evidence, and one bounded next action. This describes the workflow design; it is not a guarantee of an external result.
Do you work with general contractors and subcontractors?
GC and subcontractor coordination is represented as a distinct operating lane, separate from homeowner-facing intake. Specific participation, scope, and commitments require owner review.
