Timber Carport Structural Engineering.

We design wood-framed carports — single, double, tandem, and RV bays — from a clean architectural intent or a sketch on a napkin. The work is built for architects, ADU builders, and general contractors who need a structural set that clears plan-check the first time.

What's included

Engineering scope for timber carports

  • Gravity, wind, and seismic load analysis to ASCE 7 for your site
  • NDS-based sizing of posts, beams, rafters, and ridge members
  • Lateral system: knee braces, moment posts, or shear-panel walls as the geometry allows
  • Connection detailing: Simpson / MiTek hardware schedule with nailing and bolt patterns
  • Foundation design: spread footings, drilled piers, or thickened slab edges sized to soil
  • Anchor bolt and post-base specification with embedment and edge-distance callouts
Deliverables

What you receive

  • Stamped structural drawings (S-sheets) — plan, elevations, framing, sections, details
  • Signed and sealed structural calculations package
  • Hardware and fastener schedule
  • Foundation plan with reinforcement and anchor layout
  • Response to plan-check comments through approval
Applicable codes

We design to

  • IBC / IRC (current adopted edition)
  • ASCE 7-16 / 7-22 (wind and seismic)
  • NDS — National Design Specification for Wood Construction
  • AWC SDPWS for wood shear walls and diaphragms
  • Local amendments (CBC, FBC, NYC BC, and others as applicable)
PE-stampedPermit-readyU.S. jurisdictions
Who it's for

Built for the teams that ship the project

  • Architects who need a structural partner for residential outbuildings
  • ADU builders adding parking or storage to a primary residence
  • General contractors permitting standalone carports for homeowners
  • Developers building tract homes with attached or detached parking covers
FAQ

Timber Carports — questions, answered

Can you design a timber carport attached to an existing house?
Yes. We engineer the ledger connection, verify the existing wall framing can take the new loads, and detail flashing and lateral transfer back into the diaphragm.
Do you handle high-wind coastal and hurricane zones?
Yes. We design to the site-specific ASCE 7 wind speed and exposure category, including uplift detailing and tie-down hardware required in coastal and hurricane-prone regions.
What if the soil report shows expansive or low-bearing soils?
We size foundations to the geotechnical recommendations — drilled piers, grade beams, or deeper spread footings — and coordinate the structural design to suit.
Can the carport be designed for a future solar array?
Yes. Tell us the array weight and panel layout up front and we'll size the framing and connections so the structure can carry the future PV load without retrofit.
