DECKS, COVERS, FENCES & STRUCTURES

Exterior stairs and handrails

Create or repair outdoor steps and handrails with consistent geometry and secure connections. Measure the actual rise and landing space before selecting tread surfaces and rail materials.

START WITH THE DETAILS

What goes into
the work.

Measure footprint, height, fence length and gate count separately. Note grade, posts, access, attachment and stairs.

Typical scope to confirm

  • Measure elevation change and available stair footprint
  • Design stringers, supports and landing connections
  • Specify exterior treads and risers
  • Coordinate required handrails, guards and transitions

Make it specific to your project.

Enter the amount of work and choose the details you know. Your choices follow you into the Project Builder.

LOW / MIDDLE / HIGH REFERENCE

Low$1,400per project
Middle$2,000per project
High$2,600per project

Low and high are published reference endpoints. Middle is their arithmetic midpoint, not a quoted average, product tier or firm price.

A planning reference for this service only. Selections, local labor, access, quantities and existing conditions need Coastal’s review. Do not add overlapping whole-project and component ranges.

KNOW WHAT COMES NEXT

From first idea to finished work.

  1. Plan the scope

    Measure rise, run, landing space and railing support.

  2. Prepare and approve

    Review supports, attachment, setbacks and approvals; select materials.

  3. Complete the work

    Build approved footings and structure, then add finishes and selected accessories.

  4. Review and close out

    Check connections, gates, steps and railings; complete required inspections.

Planning & preparation
3–10 weeks
Work on site
1–4 weeks

Illustrative planning allowance for the stated scope, not a promised start or completion date. On-site time starts after approvals and materials are ready; procurement, inspection waits, curing and discoveries can extend the calendar.

PERMIT PLANNING

Check the scope and jurisdiction

Size, height, attachment, use and location determine approvals. Edmond lists exceptions for some small detached structures and fences; OKC asks owners to check shed scope before construction. Confirm setbacks, easements and utility work too.

  • Attached or substantial new outdoor structure
  • Work outside local size/height exemptions
  • Property-line, easement, utility or drainage impacts

ENGINEERING & DESIGN

Confirm design requirements

Review the load path, existing supports and proposed changes before work. An engineer may be needed for nonstandard spans, added loads, damage or a reviewer-requested design; a permit alone does not mean every detail needs engineering.

  • Load-bearing changes or uncertain framing
  • Nonstandard spans, concentrated loads or damaged supports
  • Soil, foundation or retaining conditions beyond an approved design

Confirm requirements with the city or county responsible for the property before work begins. The address, exact scope and adopted code determine the final requirements.
