Deck construction contract template
A deck looks simple from the yard, but the parts that keep it standing are the ones nobody sees: footing depth, the ledger connection to the house and the hardware holding it there. This contract covers a new deck or a tear-down and rebuild, with the materials, the structure, the permit, the property line and the warranty spelled out. Read it below, then send it from SignMaster.

If the deck is attached, its ledger will be fastened to the house framing with Ledger fasteners and flashed to keep water out of the wall.

If the lines are uncertain, the Homeowner will obtain a survey at their own cost. The Contractor is not responsible for a deck built in the location the Homeowner directed.
I have shown the Contractor the property line nearest the deck.
7. Utility locates and the site
Before digging footings, the Contractor will request a utility locate through the 811 call-before-you-dig service.

12. Warranty
The Contractor warrants the deck's structure for Structural warranty in years years and its other workmanship for Workmanship warranty in years year(s) from the final inspection. Decking, railings and hardware carry their makers' warranties.

What a deck contract protects
Deck jobs go wrong in three ways: the homeowner expected a different board, the deck went somewhere it wasn't allowed, or something structural was skipped. A contract that names the decking by brand and color, places the deck relative to the property line, and spells out the footings and ledger heads off all three. The structural part matters most, because a deck pulling away from a house is a safety failure, not a cosmetic one.
Use it for attached and freestanding decks in wood or composite, with stairs, railings and built-in benches or planters. For a patio at ground level, the concrete contract covers poured slabs and the landscaping contract covers pavers.
What the template covers
- Design: the drawing by name and date, attached or freestanding, size, height, stairs and built-ins.
- Materials: framing lumber, decking brand, line and color, the railing system, and the fastening method.
- Structure: footing size and depth, how the ledger is fastened and flashed, and what happens if the house framing there is damaged.
- Permits and approvals: the building permit, inspections that payments follow, and HOA approval the owner obtains.
- Property lines: the owner shows the line and confirms setbacks, with a survey at their cost if the line is unclear.
- Locates and site: an 811 locate before footing holes, private lines marked by the owner, and what happens to the dug soil.
- Finish and loads: when pressure-treated wood can be stained, and that a hot tub needs a design made for it.
- Payment and warranty: deposit, payments after inspections, and separate structural and workmanship warranties.
Deck contract mistakes
- Leaving the ledger unspecified. The connection to the house is where many deck failures start. Write how it's fastened and flashed, or that the deck stands on its own.
- Digging before the property line is marked. If the deck lands in a setback, it may have to be cut back. Make showing the line the owner's job before any holes go in.
- Promising a stain date. Pressure-treated wood often has to dry before it takes stain. Make staining a separate line or a later visit.
- Swapping decking without asking. Composite colors vary by brand and batch. Name the brand, line and color, and get written approval for any substitution.
- Pouring before the footing inspection. Many building departments inspect footing holes before concrete. Skip it and you may be digging them out again.
Codes and permits
Most decks attached to a house, or above a certain height, need a building permit, and many local codes follow the deck provisions of the International Residential Code. Check your building department's rules for footings, ledgers, guards and stairs, and build the permit and inspection time into the schedule.

Questions? Answers.
Do I need a permit to build a deck?
Usually, especially if the deck is attached to the house or raised off the ground. Rules vary by city and county. The template says who obtains the permit and ties payments to the inspections.
How deep do deck footings need to go?
Deep enough to meet your local code, which in cold climates means below the frost line. Your building department sets the number; section 4 has a blank for footing size and depth so it's on record.
Who is responsible if the deck crosses the property line?
Under this template, the homeowner shows the property line, confirms setbacks and easements, and pays for a survey if the line is in doubt. The contractor builds where the homeowner directs.
When can a new pressure-treated deck be stained?
Once the wood is dry enough to absorb stain, which can take weeks or months depending on the lumber and the weather. Follow the stain maker's instructions, and keep staining as its own line in the contract.
