Home Renovation Project Plan: Phases, Budget and Timeline

A home renovation project plan lists what you are changing, the order the trades will work in, a budget with a contingency line, who is doing each job and a dated timeline. A written plan protects you from the two classic problems, sequence and surprises (a vanity that arrives two weeks after the plumber, or a wall that hides rot), before demolition day.

Below you will find the phases and trade order, a sample budget with contingency, a contractor tracker, a sample timeline for a bathroom remodel and a checklist to run before work starts. All money and duration figures are example numbers to show the method, not typical prices or times.

Phases of a Home Renovation Project Plan

Every renovation, from a bathroom to a whole floor, moves through the same broad phases:

1. Scope. Write down what changes and what stays. “Replace tub with walk-in shower, new vanity, new tile floor, keep the window” is a scope. “Update the bathroom” is a wish.
2. Design and selections. Choose layouts, finishes and fixtures, with a model number or price for each.
3. Bids and permits. Collect written quotes, check licenses and insurance, and apply for any permits.
4. Ordering. Order anything with a long lead time before demolition.
5. Demolition. Strip out what is being replaced and look for hidden damage.
6. Rough-in. Plumbing, electrical and ventilation inside the open walls, followed by an inspection where your area requires one.
7. Close-up. Insulation, wall boards and waterproofing.
8. Finishes. Tile, flooring and paint.
9. Fixtures. Vanity, toilet, lights and trim, sometimes called finish plumbing and finish electrical.
10. Final inspection and punch list.

The logic behind the order: work inside the walls happens before the walls close, and messy work happens before clean work. In a kitchen, countertops are usually measured after the base cabinets are installed, so leave a gap in the timeline for fabrication. Our guide to project phases shows how the same idea applies to other kinds of projects, and a work breakdown structure helps you turn each phase into tasks with owners.

Safety and Permits

Electrical, plumbing, gas and structural work often needs a permit, and in many places it must be done by a licensed electrician or plumber. Rules vary by city and county, so check with your local building department before you plan any DIY work, and hire licensed trades wherever they are required.

Older homes can contain lead paint or asbestos. Have suspect materials tested before demolition, and turn off power at the breaker and water at the valve before working near either.

Renovation Budget Spreadsheet: Lines and Contingency

A renovation budget works best with one row per line and a note of how each line is priced: a trade’s bid, labor as hours × rate, materials as units × unit price, or an allowance. Here is an example small bathroom remodel in an older house. The homeowner paints; everything else is hired out.

Budget line	Priced as	Example amount
Design consultation	Fixed fee	$300
Permit fees	Set by the local office	$250
Demolition	Contractor’s bid	$900
Debris removal	Fixed fee	$400
Plumbing rough-in and finish	Licensed plumber’s bid	$2,400
Fan circuit, lighting and outlets	Licensed electrician’s bid	$1,300
Cement board and drywall labor	16 h × $55	$880
Boards and waterproofing	8 boards × $18 + 1 kit × $95	$239
Tile setting labor	30 h × $60	$1,800
Tile	99 sq ft × $7	$693
Thinset and grout	6 bags × $28	$168
Paint and supplies (DIY)	2 gallons × $45	$90
Vanity, toilet, shower valve and trim	Allowances: $700 + $300 + $350	$1,350
Mirror, light and accessories	Allowance	$370
Subtotal		$11,140
Contingency	15% of subtotal	$1,671
Total budget		$12,811

A few notes on the method:

• Tile quantity. The floor and shower walls measure 90 sq ft. The example orders 10% extra for cuts and breakage, which gives 99 sq ft. Ask your tile supplier how much extra your layout needs.
• Allowances are placeholders for items you have not chosen yet. If you pick a $900 vanity against a $700 allowance, the extra $200 has to come from somewhere, so record each choice against its allowance as you make it.
• Contingency. The example uses 15% because the walls have not been opened in an older house. Pick your own figure based on how much is unknown, and do not spend contingency on upgrades.
• Temporary costs. If the work takes out your only bathroom or your kitchen, add a line for the alternative, such as meals out.

For the full method behind labor, materials and contingency, see how to estimate project costs. Our project budget template prices labor, materials and fixed costs per task and compares budget with actual as you log expenses.

To see how much contingency is left at any point, put the budgeted amounts in C2:C15, the actual amounts in D2:D15 and the contingency in F1. This formula is the same in Google Sheets and Excel:

=F1-SUMPRODUCT((D2:D15<>"")*(D2:D15-C2:C15))

It only counts lines that already have an actual amount, so lines you have not paid yet do not look like savings.

Contractor Tracking

A simple tracker keeps every trade’s status in one place:

Trade	License and insurance	Written quote	Paid so far	Booked days	Status
Plumber	Checked	$2,400	$600	3–4 and 19	Booked
Electrician	Checked	$1,300	$0	5 and 20	Booked
Tile setter	Waiting for insurance certificate	$1,800	$0	10–16	On hold
Contractor (demo, boards)	Checked	$1,780	$445	1–2 and 7–9	Booked

Habits that prevent most disputes:

• Compare quotes for the same scope. If one bid includes debris removal and another does not, they are not comparable yet.
• Tie payments to finished stages, such as “rough-in passed inspection,” rather than to dates.
• Put every change in writing with its price before the work is done.
• Keep one contact list with the direct number for each trade and your inspector’s office.

Sample Renovation Timeline for a Bathroom Remodel

Planning takes longer than building. In this example, the first five weeks happen before anyone picks up a hammer:

• Weeks 1–2: write the scope, measure, set the budget and choose finishes.
• Weeks 2–4: collect written quotes and check licenses and insurance.
• Week 4: sign contracts and apply for permits. Processing times vary, so ask your local office.
• Week 5: order the vanity, tile and shower valve, and confirm delivery dates before booking demolition.

Construction then runs in working days. Starting on a Monday with no holidays, the example finishes on the Tuesday of the fifth construction week:

Working days	Step	Who
1–2	Protect floors, demolition	Contractor
3–4	Plumbing rough-in	Licensed plumber
5	Electrical rough-in	Licensed electrician
6	Rough-in inspection	Inspector
7–9	Cement board and drywall	Contractor
10–11	Waterproofing and cure time	Tile setter
12–15	Tile floor and shower walls	Tile setter
16	Grout and seal	Tile setter
17–18	Prime and paint	Homeowner
19	Vanity, toilet and shower trim	Licensed plumber
20	Lights, fan and outlets	Licensed electrician
21–22	Final inspection and punch list	Inspector, contractor

Day 6 is the hinge. If the inspector cannot come until day 9, every later step moves three days, so book inspections as early as your local office allows. Our guide on how to create a project timeline explains how to add buffers in front of fixed dates like these. Once work starts, a weekly check of each step against this table, as in our guide to tracking project progress, shows slips while there is still time to rebook a trade.

Remodel Planning Checklist

Run through this list before demolition day:

• Scope written and agreed with everyone living in the house
• Budget complete, with contingency as its own line
• Permits approved and posted where required
• Written quotes signed, with licenses and insurance checked
• Long-lead items delivered and inspected for damage
• Debris removal booked
• Floors and doorways protected, with a dust barrier on the work area
• Water shut-off valve and breaker panel labeled
• A temporary bathroom or kitchen arranged if needed
• Neighbors told about noise and parking

One last tip: when the walls are open after the rough-in inspection, photograph every wall with a tape measure in the frame. Years from now, those photos will tell you exactly where the pipes and wires run before you drill.
