Residential Decks: What You Need to Know

Residential decks and what you need to know by TimberTech

If you’re considering adding a deck to your home, you’ve likely got a lot of questions: Will my deck require a permit? Should I build it myself? What is the best material for decking?

These questions can also leave you thinking: Is it worth it?

Residential decks do require certain preparations to ensure they’re built correctly and up to code, but the benefits of a completed deck far outweigh the time and cost of prepping and building.

Residential Decks: Planning 101

Ready to learn about residential decks? We’ve got the guidance you need to plan and execute your deck project.

Dive Into Your Project

Building a deck doesn’t have to be complicated. Discover what you need to know to start your project to ensure its success.

How to start planning for residential decks

Code Compliance

Residential decks have specific code requirements that you’ll need to research before you confirm your deck design and start building. Some of these requirements are locally enforced, so check with your local building code department to ensure your deck — and potentially, railing — is designed within the proper parameters.

Will My Deck Need a Railing?

Decks that are built higher than 30 inches off the ground will require a railing. Otherwise, a railing is optional. However, there are other reasons you may want to include a railing in your build, such as:

  • Aesthetic reasons: Adds another layer of dimension and style to your deck
  • Functional reasons: Keeps people from stepping off the edge of your deck into landscaping.
  • Practical reasons: Helps guests feel more comfortable closer to the edge of the deck and keeps young children from falling off.
Residential decks typically need building permits

Building Permits

Once you confirm your deck design, you’ll likely need a building permit from your local town or city hall to start your build.

Be sure to bring a diagram of your proposed deck design with dimensions of its size and height to claim the proper permit.

If you choose to work with a contractor, they will often guide you through this process.

Budgeting 101: Considering Cost Factors

One of the most important considerations for residential decks planning is budget. There are several cost factors you’ll need to take into account, including upfront and long-term costs.  

Upfront Costs to Consider for Your Build

  • Labor – Often the costliest part of the build, which can be avoided if you decide to DIY.
  • Design – The more complex your deck design, the higher the costs.
  • Substructure – A complex design will require a more intricate substructure than a simple deck design.
  • Deck materials – Upfront costs for deck materials are only part of the story — some deck and railing materials may end up costing you more in the long-run.
  • Fasteners – Different fastener types have a higher price point than others.

Long-Term Costs: Material Maintenance, Repairs & Replacement

A major factor that affects long-term costs for residential decks is material. Why? Because your chosen deck material dictates:

While traditional pressure-treated wood may spring to mind as a popular and cost-effective option for residential decks, the reality is far from ideal.

Traditional wood is not ideal for residential decks

What’s No Good About Wood

As an organic material, traditional wood — from pressure-treated lumber to exotic hardwoods like Ipe — is prone to deterioration from moisture, UV rays, and wear and tear.

Not only does it require extensive maintenance to keep these issues at bay, but despite your best efforts, a traditional wood deck will inevitably require repairs and eventually, replacement.

Deciding whether or not to DIY your deck

Tools Available to You

Ask yourself:

  • What tools do you own vs which will you need to rent?
  • Do you feel confident using the tools the project requires?
Deck design complexity affects DIY capabilities

Deck Design Complexity

Ask yourself:

  • Are you comfortable building your deck’s height and shape?
  • Are you clear on what is needed at the substructure level?

Another factor you’ll need to consider is your project timeline. If you have a hard deadline to hit for your build’s completion, you’ll need to ensure you have time to work on the deck, as well as some flexibility to account for weather delays.
