Targeted renovation
Targeted renovation: kitchen remodels, bathroom remodels, and systems replacements (HVAC, electrical, plumbing upgrades). The process is compressed compared to major renovation: design is often contractor-led or design-build, permitting may be over-the-counter for non-structural work, and the schedule is driven by product lead times — especially custom cabinets (8–16+ weeks), countertops, and appliances. Kitchens and bathrooms have the highest risk of cost overruns among all renovation project types due to the density of MEP systems and the potential for discovering hidden moisture or plumbing issues.

1. Scoping + selections
The process begins with capturing user needs, establishing the budget, and making critical product selections early. In kitchen and bath remodels, the NKBA planning guidelines drive space planning (work triangle, aisle widths, clearances) and the selection of appliances and fixtures whose dimensions and utility requirements dictate the layout and technical plans. Selections must happen before design can proceed — this is the opposite of the new-construction sequence where selections often come later.
Terms used in this phase: programming, selections, budget, work triangle
- Owner and sponsor: Defines needs, style preferences, and budget. Makes product selections for cabinets, appliances, fixtures, and finishes.
- Architecture firms and consultants: Kitchen & bath designer (NKBA CKD/CBD) or interior designer captures requirements and applies planning guidelines. For systems replacements, the contractor may lead scoping.
- Builder and general contractor: In Design-build delivery, engaged from the start. Provides preliminary pricing based on selections.
- City county and state authorities (AHJ): Not yet involved unless pre-application inquiry is needed.
- Home inspector: Pre-renovation assessment may be performed, especially if the home is older or prior issues are suspected.
- Subcontractors and trade contractors: MEP trades may provide input on existing system capacity and relocation feasibility.
- Vendors suppliers and distributors: Critical early role: product availability, lead times, and pricing for cabinets, countertops, appliances, and fixtures drive the schedule.

2. Design + documentation
The designer produces detailed plans, elevations, and specifications based on the selected products and existing conditions. For kitchen and bath, NKBA-style drawings include floor plans, elevations, schedules, and specifications. For systems replacements, the contractor may produce a scope-of-work document rather than formal architectural drawings. Site measurements and as-built conditions are documented.
Terms used in this phase: design, elevations, specifications, Construction documents (CDs)
- Owner and sponsor: Approves the design and finalizes any remaining selections. Signs off on the scope of work.
- Architecture firms and consultants: Produces detailed drawings. For kitchen and bath, applies NKBA clearance and safety standards. Coordinates with MEP consultants if systems are being relocated.
- Builder and general contractor: Reviews for constructability. Finalizes estimate.
- City county and state authorities (AHJ): Not yet involved unless the designer has questions about code triggers.
- Subcontractors and trade contractors: Plumbing and electrical trades confirm feasibility of proposed relocations within existing structure.
- Vendors suppliers and distributors: Confirm product specifications and compatibility with existing conditions.

3. Permitting + procurement
Permits are obtained (if required) and long-lead products are ordered. Non-structural kitchen and bath remodels may qualify for over-the-counter or express permits in many jurisdictions. Plumbing and electrical relocations trigger trade-specific permits and plan check. Custom cabinet orders are placed now — their 8–16+ week lead time is usually the longest item on the critical path.
Terms used in this phase: permit, procurement, lead time, cabinet order
- Owner and sponsor: Approves final contract. Understands that cabinet lead time sets the construction start date.
- Architecture firms and consultants: Submits for permits. Responds to any review comments.
- Builder and general contractor: Pulls permits. Places orders for cabinets, countertops (slab selection), appliances. Signs subcontracts.
- City county and state authorities (AHJ): Issues permits. Over-the-counter for simple scope; full plan check for structural or MEP changes.
- Environmental consultant and abatement contractor: If pre-1978 home, lead testing occurs now. Asbestos testing if suspect materials will be disturbed.
- Subcontractors and trade contractors: Confirm crew availability windows aligned with cabinet delivery date.
- Vendors suppliers and distributors: Custom cabinets enter fabrication. Appliance orders are placed. Countertop slab may be selected.

4. Selective demo + discovery
Existing finishes, cabinets, fixtures, and non-structural elements are removed. This is when concealed conditions are discovered — moisture damage, mold, outdated wiring, non-code plumbing, or structural issues behind the walls. The Contingency budget is drawn on here. In occupied homes, containment and dust control are installed before demolition begins.
Terms used in this phase: Selective demolition, Concealed conditions, Change order
- Owner and sponsor: Approves change orders for discovered conditions. May need temporary kitchen or bathroom arrangements.
- Architecture firms and consultants: Evaluates discoveries. Updates plans if layout changes are needed.
- Builder and general contractor: Documents discoveries. Presents options with cost and schedule impact. Manages RRP containment in pre-1978 homes.
- City county and state authorities (AHJ): May be consulted if discoveries trigger code upgrades beyond original permit scope.
- Environmental consultant and abatement contractor: Returns if additional hazardous materials are found.
- Subcontractors and trade contractors: Perform selective demolition. Flag field-discovered conflicts (undersized drain, insufficient electrical capacity).
- Vendors suppliers and distributors: Product adjustments if discoveries change specifications.

5. Rough-in + inspections
With existing conditions revealed and resolved, MEP rough-in proceeds: new plumbing, electrical, HVAC ductwork, and any structural modifications. Municipal inspections occur at staged milestones before work can be concealed. In bathrooms, waterproofing inspection is a critical gate before any tile can be installed.
Terms used in this phase: rough-in, inspection, waterproofing
- Owner and sponsor: Limited active role unless change decisions are pending.
- Architecture firms and consultants: Answers field questions. Verifies installations match design intent.
- Builder and general contractor: Coordinates trade sequence and inspection scheduling. Manages occupied-home logistics.
- City county and state authorities (AHJ): Inspects rough MEP, framing (if structural changes), and waterproofing/shower-pan before surfaces are concealed.
- Subcontractors and trade contractors: Plumbing, electrical, and HVAC crews install rough-in scopes. Work must comply with current codes for altered systems.
- Vendors suppliers and distributors: Confirm cabinet delivery timing aligns with rough-in completion.

6. Finishes + installation
The visible transformation happens here. Sequence is critical and product-dependent: drywall → prime/paint → cabinet installation → countertop templating → countertop fabrication and install → tile → fixtures → appliances → trim. Countertop templating can only occur after base cabinets are fully installed, creating a necessary pause. In bathrooms, tile installation follows waterproofing inspection.
Terms used in this phase: cabinets, countertops, tile, fixtures, appliances
- Owner and sponsor: Sees the result taking shape. Late changes are expensive — Scope creep pressure is highest here.
- Architecture firms and consultants: Reviews finish quality. Addresses any remaining design questions.
- Builder and general contractor: Manages the tight installation sequence. Coordinates countertop templating, fabrication lead time, and final MEP trim.
- City county and state authorities (AHJ): Near-final inspections continue.
- Subcontractors and trade contractors: Install cabinets, tile, flooring, fixtures. Electricians and plumbers return for final trim connections.
- Vendors suppliers and distributors: Countertop slab is templated, fabricated (1–4 weeks), and installed. Appliances and fixtures are delivered for final installation.

7. Closeout + warranty
Final walkthrough, punch-list completion, final inspections, final payment with lien waivers, and warranty handoff. The owner resumes full use of the space.
Terms used in this phase: Substantial completion, Punch list, warranty, lien waiver
- Owner and sponsor: Conducts final walkthrough. Accepts completed work. Receives warranty information and product manuals.
- Architecture firms and consultants: May participate in final walkthrough on larger projects.
- Builder and general contractor: Completes punch items. Compiles closeout records. Initiates warranty period.
- City county and state authorities (AHJ): Final inspection and permit closeout.
- Subcontractors and trade contractors: Return for punch work.
- Vendors suppliers and distributors: Product warranties and manuals pass to the owner.
