Structural Options: What to Add Before You Build

Add the things that live in the framing, foundation, walls or roof before the build starts: a covered patio, extra windows, a bedroom or bath option, ceiling supports, outlets and wiring. They're far cheaper now than after drywall. Skip finishes you can change later.

What to do before you build a house?

Before construction starts, settle anything that touches the structure. Once framing and drywall are done, these get expensive or impossible.

The options most often worth it:

• Covered or extended patio. A patio ranked among buyers' most-wanted features in NAHB's 2024 survey, rated essential or desirable by 86%.
• Room options. A flex room as a bedroom, a loft, or an extra bath, if the plan offers it.
• Extra windows. More light, and harder to add later.
• Ceiling fan supports and lights. NAHB found 81% of buyers want ceiling fans. Wiring and blocking go in during framing.
• Outlets and circuits. In the kitchen, garage, outdoors and wherever you'll work or charge things.
• Low-voltage wiring. TV, data and security, run before drywall.
• Plumbing extras. A gas line for a grill or range, a utility sink, an extra hose bib.
• Blocking. Wood inside the wall for TV mounts, grab bars or heavy shelves.

What not to upgrade when building a home?

Skip the things you can swap easily later:

• Light fixtures and ceiling fan models (but do add the wiring and supports)
• Faucets and cabinet hardware
• Paint colors
• Mirrors and accessories
• Window treatments

And be careful with options that only you will value. A highly personal layout change can make resale harder.

What is the 30 rule of home renovation?

It's an informal rule of thumb, not an official standard. The version I hear most says not to spend more than about 30% of a home's value on renovations, because you're unlikely to get it back at resale. People also apply a smaller percentage to single rooms.

The useful idea behind it: spending a lot more than the neighborhood supports rarely pays back. On new construction, that's another reason to choose structural options that broad groups of buyers want, like a patio or an extra bath, over expensive one-off changes.

The cost of waiting

From my time on job sites: adding an outlet before drywall is a short task for an electrician. Adding it after means cutting drywall, fishing wire, patching, texturing and painting. A covered patio added later means permits, footings, roof tie-ins and matching materials.

That's why the structural option deadline matters. Ask your builder:

• When is the deadline for structural options?
• Which options require engineering or permit changes?
• How do structural options affect the price and the timeline?

Check them before drywall

At your pre-drywall walkthrough, confirm every structural option you picked is actually there: the patio framing, the windows, the outlets, the blocking, the wiring. That's the last easy chance to catch a miss.
