Timeline questions are the ones most contractors answer with the minimum number that gets the client comfortable enough to sign. The honest version of every remodel timeline is longer than the number you were probably quoted — not because projects run late, but because the quoted number usually excludes the design phase, the permitting phase, and the material procurement phase. A kitchen remodel that takes 12 weeks to build has already taken 12–18 weeks to design, permit, and source before the first wall comes down. Here is what each project type actually takes, from design start to move-back, in the East Bay in 2026.
Kitchen, Bathroom, and Whole House Timelines
A quality kitchen remodel takes 18–26 weeks from design start to move-back. The breakdown: design runs 6–10 weeks, permitting runs 5–10 weeks (concurrent with material procurement for long-lead items), custom cabinetry takes 10–16 weeks from order to delivery, and construction runs 10–16 weeks. Add the punch list and final inspection. Anyone promising 12 weeks total for a kitchen remodel in Pleasanton or a kitchen remodel in Danville has not accounted for all phases. The construction phase is actually the fastest part. The pre-construction phases are where the timeline lives.
A master bathroom remodel takes 12–18 weeks from design start to completion: design runs 4–8 weeks, permitting runs 3–8 weeks, and construction runs 6–10 weeks. Add 4–6 weeks if any structural modification is involved. A whole house remodel is a different scale entirely: design runs 10–18 weeks, permitting runs 8–16 weeks, and construction runs 20–36 weeks depending on scope — making the total timeline 10–18 months from design start. For a whole house remodel in Walnut Creek, anyone promising 6 months from start to finish is either doing production-level design work or is not accounting for all phases honestly.
Jurisdiction matters significantly in the East Bay. Pleasanton typically runs 5–7 weeks for plan check. Danville runs 5–8 weeks. Walnut Creek runs 6–10 weeks. Orinda and Lafayette run 8–14 weeks. Unincorporated Contra Costa County runs 8–12 weeks. Hillside projects in Lafayette, any HOA review in Blackhawk or Ruby Hill, and geotechnical report requirements in certain zones add further time. These are not delays — they are predictable phases that a properly managed design-build firm accounts for in the project schedule from day one. The Danville Dream project involved HOA review coordination that added 6 weeks to the permitting phase — we built that into the original schedule rather than calling it a delay.
Addition, ADU, and Custom Home Timelines
A home addition takes 10–15 months from design start: design runs 10–16 weeks, permitting runs 10–18 weeks (additions often trigger full site review including grading, drainage, and landscape), and construction runs 16–28 weeks. For home additions in Lafayette, planning department involvement and design review add time that design-only firms sometimes don't account for until they're already in it.
An ADU takes 9–14 months from design start: design runs 8–12 weeks, permitting runs 8–16 weeks (some cities have ADU-specific fast-track programs, but "ministerial approval" is not the same as fast processing), and construction runs 16–26 weeks. An ADU in Pleasanton moves through plan check differently than one in an unincorporated county area — those distinctions affect procurement timing and subcontractor scheduling in ways that affect your move-in date. A custom home takes 18–30 months from design start: design runs 16–28 weeks, permitting runs 16–24 weeks, and construction runs 40–60 weeks.
What Extends Timelines and What Doesn't
The most common timeline extender is custom cabinetry ordered after permit approval rather than concurrently with permit processing. This single decision adds 10–16 weeks to construction start — the lead time for custom cabinetry doesn't compress because you need it sooner. A well-run design-build firm submits for permits while simultaneously procuring long-lead materials, so permitting and procurement happen in parallel rather than in sequence.
Design changes after permit submittal are the second most common extender — any change that affects permitted drawings requires a permit amendment, which restarts some or all of the plan check process. The design phase exists precisely to prevent this: every material, dimension, and configuration decision should be made before the drawings go to the building department. The goal is zero amendments after submittal. If you need your kitchen or whole house remodel complete by a specific date — a child starting school, a family event, a parent moving in — work backward from that date and add 26 weeks to determine when design needs to start. Then call us. Start a project conversation and we'll give you an honest timeline for your specific scope and jurisdiction.
