Complete Remodel Permitting, General Contractor Markup & Contingency

Separate the three major budget layers

A remodel estimate is easier to evaluate when it separates direct construction costs, contractor compensation, and owner-held risk reserves. These categories serve different purposes and should not be blended into one unexplained percentage.

1. Direct construction costs: Labor, subcontractors, materials, equipment, disposal, and other work included in the scope.
2. General contractor overhead and profit: Compensation for project management, supervision, estimating, insurance-related business expenses, office operations, and profit. The exact items included depend on the contractor’s pricing method.
3. Contingency: A reserve for defined unknowns, concealed conditions, design development, and approved changes. It is not automatically a fee owed to the contractor.
4. Permitting and government fees: Application, plan review, permit issuance, inspection, and possible closeout charges established by the local authority.

Keeping these layers separate helps prevent double counting. For example, a contractor may include some permit administration in overhead, while the government’s permit and plan-check charges remain reimbursable project costs. The proposal should state which fees are included, which are billed at cost, and which are excluded.

For a detailed room-by-room budget, a complete kitchen remodel cost sheet can help organize direct costs before adding contractor compensation, permitting, and contingency.

Calculate a line-item contingency reserve

A 15% to 20% contingency is a planning range, not a universal rule or a promise that the project will stay within that amount. The appropriate reserve depends on the age and condition of the home, how complete the drawings are, whether walls or floors will be opened, and how much of the work is specified before contracting.

Instead of placing an unexplained percentage on the entire project, identify the cost base and show the reserve as its own line item. A simple planning example looks like this:

The calculation is simple: contingency equals the selected percentage multiplied by the cost base. The important question is what belongs in that base. Some estimates apply contingency to direct construction costs only. Others include certain design, permit, or subcontractor costs. There is no single calculation method that applies to every contract, so the written estimate should identify the base and whether the reserve is controlled by the owner, the contractor, or both.

What contingency can cover

• Concealed water damage, rot, or deterioration found after demolition.
• Existing wiring, plumbing, framing, or structural conditions that differ from available drawings.
• Required repairs discovered during inspection or code-related correction work.
• Owner-approved changes made after the original scope is priced.
• Reasonable design development when selections or details were not final at contract signing.

What contingency should not hide

• Known work omitted from the bid.
• Routine labor or materials already included in the contract price.
• Contractor errors, defective workmanship, or ordinary project administration.
• A vague allowance that has no unit, quantity, or selection basis.
• Unapproved upgrades that the homeowner did not authorize.

Ask for written change documentation whenever contingency funds are used. The record should identify the condition or change, the cost, any credit, the remaining reserve, and the homeowner’s approval if the contract requires it.

Understand general contractor overhead and profit markup

A general contractor’s overhead and profit markup compensates the business for managing the project and carrying the risk of delivering the contracted work. For planning, a 15% to 25% range is commonly used, but it is not a legal or universal rate. The actual percentage may be lower or higher based on project size, complexity, location, market conditions, contract type, and what services the contractor provides.

Markup is also different from profit margin. If a contractor adds 20% to a $100,000 cost base, the price becomes $120,000. The $20,000 difference is 16.7% of the final price, not 20% of the final price. Ask which term the proposal uses and whether the percentage is applied to subcontractors, materials, change orders, permits, allowances, and other reimbursable costs.

This example does not establish a market price and does not determine how a particular contractor must bill. It only shows the arithmetic when the percentage is applied to $100,000. A fixed-price contract may embed overhead and profit in each line item rather than show one separate markup line. A cost-plus contract may state a fee percentage, a fixed fee, or both.

Questions to ask about the markup

1. What exact costs form the markup base?
2. Does the percentage apply to subcontractor invoices, materials, equipment rentals, and permit fees?
3. Are contractor overhead and profit already embedded in each line item?
4. Does the same markup apply to approved change orders?
5. Are allowances marked up when converted to actual purchases?
6. Are unused contingency funds returned, credited, or retained under the contract?
7. Which project administration services are included in the markup?

A clear scope makes these questions easier to answer. Before requesting comparable bids, use a written remodeling scope of work that lists demolition, structural work, finishes, allowances, permits, cleanup, testing, and closeout responsibilities.

Budget for municipal plan-check and permit fees

Permit and plan-check charges are set by the applicable local authority, not by a national remodeling price list. Fees may depend on the project valuation, type of permit, number of reviews, trade permits, resubmittals, inspection services, or other locally defined factors. Some jurisdictions publish a fee schedule, while others calculate charges through a valuation table or project-specific review.

Do not treat a contractor’s rough allowance as the final government charge unless the proposal says it is a fixed amount and the contractor accepts responsibility for any difference. Ask the building department or permitting office for the current fee schedule and confirm whether the project requires separate building, electrical, plumbing, mechanical, zoning, historic-review, or other applications. The exact requirements vary by location and scope.

Plan-check fees deserve special attention when drawings are incomplete or the project may require revisions. A resubmittal or plan revision can create additional charges in some jurisdictions, while others include a defined number of review cycles. Only the local permitting office can confirm the applicable process and fees.

Permit budget checklist

• Identify the local authority having jurisdiction, often the city or county building department.
• Ask which permits and approvals apply to the proposed scope and property.
• Request the current fee schedule or fee-calculation method.
• Ask whether plan review, permit issuance, inspection, resubmittal, and closeout fees are separate.
• Confirm who prepares drawings, submits applications, responds to comments, schedules inspections, and pays each charge.
• Keep copies of applications, approved plans, correction notices, receipts, and inspection results.

A permit allowance should be labeled as an estimate unless the responsible agency has provided a confirmed amount. Local amendments, property-specific conditions, and changes to the submitted scope can affect the final charge.

Write the contract so budget controls are visible

The contract should connect the scope, price, markup, allowances, contingency, and approval process. A low headline price is difficult to compare when one contractor includes permits and another excludes them, or when one bid marks up subcontractors and another does not.

At minimum, request a schedule or exhibit showing:

• Direct work by trade or phase.
• Material allowances with quantities, units, and selection assumptions.
• Permit and plan-check responsibilities.
• Overhead and profit amount or calculation method.
• Contingency amount, permitted uses, approval process, and remaining-balance treatment.
• Payment milestones tied to completed work or documented procurement.
• Change-order requirements, including written price and schedule impacts before the changed work starts.
• Inspection, punch-list, cleanup, testing, and final closeout responsibilities.

For a fixed-price contract, confirm which items are truly fixed and which are allowances or owner selections. For cost-plus work, confirm how invoices will be documented and how the contractor’s fee is calculated. For either arrangement, exclusions should be as specific as inclusions.

Contractor due diligence also supports budget control. Before signing, homeowners can learn how to check contractor license discrepancies online and verify that the business information matches the contracting entity. License and insurance checks do not guarantee performance, but they can reveal information that warrants further questions.

Plan for final inspections and occupancy sign-off

Permit closeout is not complete merely because construction appears finished. The contractor should identify all required final inspections, testing, documentation, and agency sign-offs. Depending on the jurisdiction and scope, the final document may be a Certificate of Occupancy, an amended or temporary occupancy approval, a final inspection approval, or another locally used closeout record. Not every remodel requires a new Certificate of Occupancy.

The local building department determines whether a Certificate of Occupancy or equivalent approval is required. Confirm this before work begins, especially when the project changes use, adds conditioned space, creates a new dwelling area, alters egress, or substantially changes the permitted layout. The permitting office can explain the applicable closeout procedure for the property and scope.

Typical closeout sequence

1. Complete the work covered by the approved plans and permits.
2. Correct open inspection items and document approved changes.
3. Schedule required final building and trade inspections.
4. Provide required test reports, product documentation, affidavits, or other closeout material if requested by the jurisdiction or project documents.
5. Confirm that each permit shows final approval or a closed status through the local authority.
6. Obtain the Certificate of Occupancy or equivalent final approval when the jurisdiction requires one.
7. Collect warranties, lien releases where applicable, paid invoices, as-built information, keys, manuals, and a final change-order ledger.

Do not assume that a contractor’s statement that the job is complete is the same as governmental approval. Ask for copies of final inspection results and the occupancy or closeout document. If the contractor will not provide them, contact the permitting office directly to ask how the property’s permit records can be verified.

Use a complete planning worksheet

A practical budget worksheet can show the relationship between the components without pretending to know the final local fees or contract price:

Before authorizing construction, check that every percentage has a stated base, every allowance has an assumption, and every excluded item has an owner. Then compare the total available budget with the planned contract price plus the owner-held reserve. If the result leaves no room for financing costs, temporary housing, storage, utility work, design revisions, or owner selections, the budget is not yet complete.

Frequently asked questions

Is a 20% contingency enough for a whole-home remodel?

It may be a reasonable planning starting point, but it is not guaranteed to cover every project. Older homes, incomplete plans, extensive demolition, structural work, and uncertain utility conditions can justify a larger reserve. Ask the design and construction team to identify project-specific risks, and keep the reserve separate from the contractor’s fee.

Should contingency be added before or after GC markup?

There is no universal calculation order. Some contracts apply markup to approved change costs, including work paid from an owner contingency, while others treat the contingency as an owner-controlled reserve outside the contractor’s fee. The contract should state the cost base, calculation order, and whether contingency-funded changes receive overhead and profit markup.

Are permit and plan-check fees included in a contractor’s markup?

They may be included, excluded, or billed as reimbursable costs depending on the contract. Government fees and the contractor’s labor for preparing or coordinating permits are different items. Ask for both to be identified separately and verify government charges with the local permitting office.

Does every remodel need a Certificate of Occupancy?

No. Whether a new, amended, or equivalent occupancy approval is required depends on the jurisdiction and the project scope. Confirm the requirement with the local authority having jurisdiction, particularly when the remodel changes use, adds living space, affects egress, or modifies the permitted occupancy arrangement.

What should a homeowner receive at final project closeout?

Request final inspection approvals, permit records showing closure, any required Certificate of Occupancy or equivalent document, approved change orders, warranties, manuals, product records, lien-related documents where applicable, and a written list of incomplete or excluded work. The exact package depends on the contract and local requirements.
