Key Takeaways
- The seams between trades, where one crew’s work meets the next crew’s, deserve as much attention as the materials.
- Footings, drain lines, and utility runs are easiest to place before any surface goes in and hard to fix after.
- Department of Energy guidance has patio slabs within 10 feet of the house sloping away from it at 2%.
- Each contractor answers for its own scope, so ask who answers for the joint where two scopes meet.
- One contractor consolidates contracts, drawings, and permits, but subcontractors and liens remain, so ask for license numbers and lien releases either way.
Picture a Southern California yard with a new patio cover, fresh paving, and an outdoor kitchen. You may think that they used one contractor to build a backyard, but it’s more likely that there were three companies working from three sets of plans.
Every crew can do good work, and the yard can still come out wrong, because nobody was asked to own the places where one crew’s work meets the next one’s.
Those places are where homeowners can end up doing the project manager’s job. You carry the drawings between trades, you spot the conflicts, and you find out who answers for a problem after it shows up.
Below, we walk through where backyard projects with several contractors tend to break, the build order that heads off most of it, and the questions worth asking before you sign anything.
Footings, Drainage, and Utility Lines Are Hard to Fix After Paving
The seams in the ground cost the most to correct, because the fix usually means tearing out finished work. Three are worth settling on paper before anyone mobilizes.
Say the paving goes down first, and then the patio cover needs posts where the pavers already sit. The crew cuts the surface open, pours the footing, and patches the cut, and the patch shows.
Putting footing locations on the drawing before anyone sets a paver avoids the repair, and our comparison of patio covers, pergolas, and louvered roofs shows how each structure changes where the posts land.

Drainage is the quieter version of the same problem, because a slab poured level, or tilted slightly toward the house, looks fine the day it is finished.
The U.S. Department of Energy’s Building America Solution Center recommends that patio slabs within 10 feet of the house slope away from the foundation at 2%.
Why? Because water pooling at the foundation can cause moisture intrusion and invite pests and mold. Fixing the slope after the concrete is poured is difficult and expensive.
That is guidance, and local code controls, so check with your building department. The slope sits between whoever grades, whoever pours, and whoever builds the structure, so it needs one owner before anything is poured.
The third is underground lines. An outdoor kitchen needs gas and power, a louvered roof needs a circuit, and lighting needs conduit, and anything missing from the plan means trenching through new paving.
California Government Code 4216 covers notice before excavation, and the City of Victorville tells residents to call 811 at least two working days before digging. List every underground run on the drawing before the first shovel goes in.
Permits, Schedules, and Warranties Have Seams Too
Not every seam sits in the dirt. Some sit in approvals, calendars, and warranties, where each contractor is covered for its own piece and nobody is covered for the space between.
An HOA might approve the patio cover, and then the paving, the kitchen, or the lighting changes after approval. Each scope of work can carry its own permit and its own inspections, and the rules change from city to city. Riverside County, for example, lists four patio categories with different inspection sequences.
On our cover projects, we handle permit applications and HOA approvals, and a complete plan up front gives the reviewer the whole picture. Our guide to HOA approvals covers the review, and our Palm Springs and Palm Desert permit posts cover local steps.
Schedules get the same treatment. The paving crew waits on the cover crew, the kitchen waits on the electrician, and you are the only person who sees all three calendars.
Don’t forget about warranties. If a problem shows up where the cover meets the slab, each contractor can point to the other’s scope, because each stands behind its own work and the joint belongs to nobody unless someone assigns it.
Our Alumawood and 4K covers come with lifetime warranties against defects, and that warranty covers the cover. Ask every contractor on your yard who answers for the joint where their work meets someone else’s, and get the answer in writing.

The Build Order for a Patio Cover, Hardscape, and Outdoor Kitchen
Footings and underground lines go in first, and the finished surface goes in last. Here is the order we plan around, adjusted for each site, soil type, HOA, and city.
- Draw the whole yard once: structure footprints, finished levels, drainage, and utility runs.
- Get HOA review and building permits for each scope of work.
- Call 811 at least two working days before digging.
- Rough grade the site so water moves away from the house.
- Run the underground lines: conduit, gas, water, and drains.
- Pour the footings for cover posts, walls, and any deck posts.
- Build the walls and framing that set heights.
- Install the patio cover frame and roof, plus any deck framing.
- Set the hardscape surface to its final pitch, then add lighting, planting, final grade, and a walkthrough.
The drawing in step 1 does most of the work, because every later step repeats a decision made there. Share it with every trade, and name one person who can say “not yet” when a crew wants to go out of order.
Whether the cover frame goes up before or after the paving depends on equipment access and layout, so we confirm it for each yard.
Still deciding what to build? We offer a planning guide to help you get the process started. Our patio cover, hardscape, and landscaping pages show the work.

What One Contractor Changes for a Southern California Backyard
One contractor gives you one contract, one schedule, and one set of drawings, and it gives the seams an owner. It does not remove subcontractors, permits, or lien paperwork.
On our patio cover projects, we assign a project manager as your single point of contact, and we coordinate with any other contractors on your property.
The Contractors State License Board (CSLB) says in its project checklist that your contractor should pull the necessary permits and schedule inspections, so ask who will and get the answer in writing.
A prime contractor still hires subcontractors and suppliers, and an unpaid contractor, subcontractor, supplier, or worker can file a mechanic’s lien, meaning a homeowner can end up paying twice. One contractor consolidates the paperwork but does not erase it.
On cost, ask every contractor for an itemized proposal so you can compare scope line by line. For market ranges on a single cover, see our Inland Empire and Palm Springs cost posts, and if resale is on your mind, read what a patio cover is worth when you sell.
What to Do If You Already Have Other Contractors on Site
The same plan works when you have already hired the pool builder, the landscaper, or the concrete crew. Share one drawing with every trade, hold one meeting before anyone mobilizes, and write down the order of work. Ask each crew to confirm footing locations, grades, and utility runs against that drawing while the ground is still open.

Questions to Ask Before You Sign a Backyard Contract
These questions come from CSLB’s consumer checklist and lien guide, and they protect you whether you hire one contractor or several.
Don’t be afraid to print this list out and bring it with you to any conversation with a contractor.
- Do the contractor’s and every subcontractor’s license numbers check out in CSLB’s License Check tool?
- Who pulls the permits and schedules the inspections?
- Is the payment schedule tied to completed phases, with the final payment held until you are satisfied?
- Is the down payment limited to 10% or $1,000, whichever is less? A contractor with a blanket performance and payment bond on file is the exception.
- Will you get a conditional lien release before each payment, and an unconditional release from each party you paid?
- Are changes in writing and signed by both sides?
- Who answers for the joint where your work meets another contractor’s?

Frequently Asked Questions
What problems come up when you hire separate contractors for a backyard project?
Problems can appear wherever one contractor’s work meets another’s: a footing that lands in finished paving, a patio that slopes toward the house, an underground line nobody planned, or an approval that covers only one piece. A single drawing and one owner of the order of work give each of those gaps someone to answer for it.
Who is responsible when two contractors’ work doesn’t line up?
Each contractor answers for its own scope under its own contract, so the joint between two scopes belongs to nobody unless someone is assigned. Ask each contractor, before you sign, who answers for the joint, and get the answer in writing. This is general information, not legal advice.
What order should a patio cover, deck, and patio be built in?
Footings and underground lines go first, and surfaces go last. The sequence runs from one drawing and approvals through grading, underground lines, footings, framing, and the cover, then paving and finishes. It shifts with the site, your HOA, and your city.
Should a patio slope toward or away from the house?
Away from it. The U.S. Department of Energy’s Building America Solution Center recommends that patio slabs within 10 feet of the house slope away from the foundation at 2%. That is guidance, so confirm the figure with your building department before the slab is poured.
Is it cheaper to hire one contractor for the whole backyard?
We can’t point to neutral data that says so, and we won’t claim it. What changes is the number of contracts, schedules, and drawings you manage. Ask each contractor for an itemized proposal and compare scope line by line.
Does hiring one contractor protect me from mechanics liens?
No. An unpaid contractor, subcontractor, supplier, or worker can file a lien, and a homeowner can end up paying twice, according to the Contractors State License Board. Get a conditional lien release before you pay and an unconditional release from each party you paid.
