Why a Pre-Construction Checklist Matters

Starting a major home project — whether it's a kitchen remodel, a room addition, or a full bathroom gut — without a structured pre-construction review is one of the most common and costly mistakes homeowners make. Work that begins before permits are issued can be ordered to stop by local inspectors, leaving your home partially torn apart. Contractors who start without a signed contract have no binding scope of work, which opens the door to disputes over cost and quality.

This checklist is designed to walk you through every step that should be confirmed before the first tool touches your home. Completing it thoroughly can prevent schedule delays, code violations, unexpected costs, and safety hazards. The home maintenance hub is a useful complement once your project is complete and routine upkeep begins.

Permits & Legal Requirements

Contact your local building department to determine which permits your project requires — structural, electrical, plumbing, and mechanical permits are commonly separate. Must
Submit permit applications and obtain all necessary approvals before any work begins. Must
Confirm whether your property is in a historic district, HOA jurisdiction, or flood zone, as these may impose additional review processes. Must
Post any required permits visibly on-site as directed by your local authority. Must

Site & Utility Safety

Call 811 (the national 'Call Before You Dig' service) at least three business days before any excavation to have underground utilities marked. Must
Identify the locations of your main water shutoff, electrical panel, and gas shutoff so they can be accessed quickly in an emergency. Must
Establish a clear, safe access path for workers and delivery vehicles that does not block emergency egress from the home. Should
Arrange for a dumpster or waste removal plan before demolition begins to keep the site safe and organized. Should

Contracts & Contractor Vetting

Verify that your contractor holds a current state license and carries both general liability insurance and workers' compensation coverage — request certificates directly from their insurer. Must
Sign a detailed written contract that specifies scope of work, materials, payment schedule, start and completion dates, and a change-order process. Must
Obtain at least two to three itemized written bids before selecting a contractor, and ask for references from comparable recent projects. Should
Confirm who is responsible for pulling permits — the licensed contractor should typically handle this, not a subcontractor. Must

Budget & Financing

Establish a firm total budget, including a contingency reserve of at least 10–20% for unexpected conditions or scope changes. Must
Confirm your financing is in place and funds are accessible before signing a contract or authorizing work to begin. Must
Review the payment schedule in your contract — avoid agreements that require more than 10–15% upfront before materials are ordered. Should

Home & Neighbor Preparation

Notify adjacent neighbors of the planned project, anticipated noise, and estimated timeline as a courtesy and to reduce friction. Should
Arrange temporary housing, storage, or adjusted daily routines if the project affects kitchens, bathrooms, or primary living areas. Should
Protect HVAC systems from dust and debris by sealing off vents in unaffected areas and changing filters more frequently during construction. Nice to have
Contact your homeowner's insurance provider to confirm your policy covers the project phase and any liability during construction. Should

Final Pre-Start Verification

Walk the site with your contractor the day before work begins to confirm shared understanding of scope, access, and any hazards. Must
Confirm all material lead times and delivery dates so the project schedule doesn't stall waiting for back-ordered items. Should
Establish a clear communication method and schedule with your contractor — weekly check-ins reduce surprises and keep the project on track. Nice to have

What to Have Ready Before Work Begins

Preparation isn't just about paperwork — it's also about having the right tools, the right people, and the right information in place. Below are the key resources and professionals you'll want to engage or consult before your project kicks off.

Required

Local Building Department

The primary source for permit requirements, code questions, and inspection scheduling for your specific jurisdiction.

Required

811 / Call Before You Dig

The free national utility-marking service required before any digging or excavation on your property.

Required

Licensed General Contractor

Manages the overall project, coordinates subcontractors, and is responsible for code-compliant work under a signed contract.

Required

Homeowner's Insurance Policy

Review your policy with your provider to confirm coverage during active construction and understand any liability gaps.

Optional

Project Management App or Notebook

Tracks decisions, change orders, receipts, and communications throughout the project for easy reference.

Keep in mind that requirements vary significantly by municipality. What needs a permit in one county may not in another. Always verify local code requirements directly with your building department rather than relying on a contractor's word alone.

Never Skip the Permit Step

Unpermitted work can void your homeowner's insurance coverage for related claims, create significant obstacles when you sell the home, and in some cases require demolition and rebuild at your own expense. If a contractor tells you permits aren't necessary for a project that clearly involves structural, electrical, or plumbing changes, treat that as a serious red flag.

Change Orders Must Always Be in Writing

Verbal agreements about scope or cost changes during a project are extremely difficult to enforce. Before any deviation from the original contract is acted upon, require a signed written change order that specifies the additional cost and any schedule impact. This protects both parties and prevents end-of-project billing disputes.
