Remodel Planning
Updated September 2026
Late selections, a failed inspection, a cabinet order placed after demolition, a wall that hides rot. Each one costs a predictable number of days, and most are preventable before construction starts. Here are the eight causes, ranked, with the fix for each.

Remodeling schedules move for a short list of reasons, and the list is the same on almost every project. That's useful, because a short list can be planned against. This guide ranks the eight causes by how often they show up and how much time each one costs, says what prevents each, and shows what a schedule update should look like when something does move.
Built by Design's published case studies record construction windows of 9 to 16 weeks. The projects that hold their dates are not the ones with no surprises. They're the ones where the surprises were on the schedule before they happened.
For the phases themselves and the weeks BBD recorded, read how long a whole-home remodel takes.
Ranked by how often they happen on residential remodels and how much time each usually costs when it does. The days are typical ranges, not promises; the point is the order of magnitude and the prevention.
| Cause | Typical cost | Prevented by |
|---|---|---|
| 1. Selections made after the phase that needs them | Days to weeks; a late tile choice can idle a bathroom for a week | Every selection made and priced before ordering; deadlines on the schedule |
| 2. Long-lead items ordered late | The lead time itself, often 6 to 12 weeks for custom cabinetry | Order during permit review, before demolition |
| 3. Inspections not scheduled ahead | A few days to a week per inspection, more if one fails | Inspection dates on the schedule the week rough-in starts |
| 4. City plan review longer than assumed | Days to weeks before construction | Ask the review time when applying; count it before promising a start |
| 5. Concealed conditions | Days for a decision, more if a redesign is needed | A contingency in the budget and a written process for changes |
| 6. Trade handoff gaps | A day or two each; they add up | One schedule the trades work from, with the next trade booked before the current one finishes |
| 7. Deliveries damaged, wrong, or backordered | Days to weeks depending on the item | Order early, inspect on delivery, keep an alternate for anything discontinued |
| 8. Weather (exterior work) and household decisions | Days | Sequence exterior work by season; agree on who decides and how fast |
The single most common delay is a decision that arrives after the work that depends on it. Tile has to be chosen before the shower is waterproofed, because the drain and the niche depend on the tile size. Cabinets have to be chosen before the electrician roughs in, because the outlets and the lighting depend on the cabinet plan. A faucet has to be chosen before the plumber sets the valve. The second most common is the order placed late. Custom cabinetry is the usual example: lead times commonly run six to twelve weeks depending on the maker and the season, and cabinets install around week 9 of a typical BBD basement schedule. Ordered after demolition, they arrive after the crew is waiting. Ordered during permit review, they arrive on time. The prevention is the same for both: every selection made and priced before anything is ordered, and every long-lead item ordered before construction starts. That's why BBD's written scope includes the selections, not allowances for them.
Inspections gate trades. The framing, rough electrical, rough plumbing, and rough mechanical inspections happen before insulation and drywall, and nothing after them can start until they pass. An inspection that isn't scheduled until the rough-in is finished waits on the inspector's calendar; an inspection that fails waits for the fix and the reinspection. On BBD's recorded basement schedules the rough-ins land in weeks 3 to 5 and drywall in weeks 6 to 8; the inspection sits in between and is scheduled the week the rough-in starts. City plan review is the same problem earlier in the process. Review time varies by city, by scope, and by season, and an addition with structural and energy review takes longer than a basement finish. Ask the department when you apply, and don't promise a start date until the answer is on the schedule.

Walls hide things: a beam smaller than the span needs, a drain that runs the wrong way, wiring from an earlier remodel, moisture behind a basement wall, no insulation where there should be some. Selective demolition finds them, and none of them can be seen from the finished side beforehand. What can be planned is the response: a contingency in the budget so the fix doesn't wait on a funding decision, and a written change process so the decision takes a day and not a week. An honest remodeler will say what they can't see. Ask what conditions would change the plan, what the contingency is, and how a change gets documented and priced.

A remodel is a relay. The drywall crew follows the inspector, the painter follows the drywall crew, the tile setter follows the painter in the bathroom and the cabinet installer follows the painter in the kitchen, the countertop template follows the cabinets, and the counters arrive one to two weeks after the template. Each handoff that isn't booked ahead costs a day or two while the next trade fits the job into their week. Over a 14-week project that's a week of drift from handoffs alone. The prevention is one schedule that every trade works from, with the next trade booked before the current one finishes. Built by Design builds with the same trade partners named in each case study, which is most of what makes that booking reliable.
Deliveries arrive damaged, wrong, or backordered. The prevention is ordering early enough to reorder, inspecting on delivery rather than on install day, and keeping an alternate for any item that could be discontinued. Weather matters for exterior work: an addition's roof tear-off, a walkout, exterior siding. Sequence those by season and build a weather day or two into the exterior phase. Household decisions are the delay nobody puts on the schedule. A question about a paint color that sits in an inbox for four days is four days. Agree at the start who decides, how questions arrive, and how fast they get answered. Many BBD projects are built with the family in the house, which makes the daily decision loop short, and that's part of why they hold their dates.
A schedule will move. The difference between a project that feels controlled and one that feels chaotic is whether the move arrives in writing, with the cause, the new dates, and what it means for the rooms you're living in. A useful update reads something like this: "The rough plumbing inspection on Thursday flagged the vent on the bar sink. The plumber corrects it Friday; reinspection is booked for Monday. Drywall moves from Monday to Wednesday. Cabinets are still due the week of the 20th, so the finish dates hold. The kitchen upstairs stays open throughout." That's the standard to ask for: cause, correction, new dates, and the effect on your household. If updates arrive without one of those four parts, ask for the missing one.

FAQAnswers, by design
The schedule questions homeowners ask once a remodel is under way, answered from how BBD runs its projects and the causes that move dates on almost every job.
Information arriving late: selections made after the phase that needs them, long-lead items like cabinetry ordered after demolition, and inspections scheduled after the rough-in finishes. Those three are preventable before construction starts. Concealed conditions are the biggest unpreventable cause, and a contingency keeps them to days.
Plan the buffer where the risk is: a few days around each inspection, the full lead time on every custom item, and a weather allowance on exterior phases. A blanket percentage hides where the risk actually sits. Ask your remodeler which weeks in the schedule carry buffer and why.
Ask for a schedule with definitions and a written update process instead. A guaranteed date either has a large hidden buffer or will be broken by the first concealed condition. A schedule that shows the inspections, the deliveries, and your decision deadlines is more useful than a promise.
It changes who manages it. One team owns design, selections, ordering, permits, and construction, so late selections and late orders are the team’s problem to prevent rather than a gap between a designer and a builder. It doesn’t remove city review time, lead times, or what a wall hides.
Four things, in writing: the cause, the correction and who is doing it, the new dates and which downstream dates hold, and what changes for the rooms you use. If an update is missing one of those, ask for it.
Custom cabinetry commonly takes six to twelve weeks depending on the maker and the season, and it installs around week 9 of a typical basement or kitchen schedule. That’s why it should be ordered during permit review, before demolition, once every cabinet decision is final.
