Deck Design for New, Replacement, and Modified Structures

A successful deck project begins with plans developed for the actual property and proposed structure. DrBalcony prepares site-specific deck designs that account for the deck’s dimensions, height, framing, connections, loads, support system, and surrounding site conditions.

Our team can design a completely new deck or prepare structural plans for the replacement, expansion, or modification of an existing deck.

Our deck design services are available for:

  • New attached or freestanding decks
  • Replacement decks and complete deck reconstruction
  • Deck expansions and structural modifications
  • Second-story and elevated decks
  • Rooftop decks
  • Hillside and sloped-lot decks
  • Residential and multifamily properties
  • Decks combined with pergolas or patio covers

Why Generic Deck Plans Are Not Enough

Generic deck plans are created for typical conditions. They do not account for the dimensions of your proposed deck, the configuration of your property, the way the structure connects to the building, or the loads and site conditions that affect the design.

Generic Deck Plan

  • Based on standard assumptions
  • Not designed for your property
  • Does not address actual site conditions
  • May omit critical framing and connection details
  • Does not include project-specific calculations

DrBalcony Deck Design

  • Designed for your specific deck
  • Based on actual dimensions and site conditions
  • Structural framing and connections detailed
  • Engineering calculations included
  • Prepared by licensed California engineers

How It Works

Most deck designs are completed within 5–10 business days after we receive the required project information.

Step 1

Request Your Design Quote

Tell us what you want to build, replace, expand, or modify. Include any available measurements, photographs, sketches, or property information.

Step 2

We Review the Property and Project

Our team reviews the proposed deck configuration, site conditions, building attachment, elevation, and structural requirements.

Step 3

We Design and Engineer the Deck

We prepare the structural layout, framing, supports, connections, details, and engineering calculations for the proposed structure.

Step 4

You Receive the Completed Plans

You receive a coordinated deck plan set that can be used for contractor pricing, construction planning, and permit preparation when required.

What’s Included

Your deck design package is developed around the specific structure and property. The final scope may vary by project, but a typical design package includes the following components.

  • Site and Deck Layout
    The proposed deck location, dimensions, orientation, building relationship, and relevant site conditions.
  • Structural Framing Plan
    The layout and sizing of joists, beams, posts, supports, and other structural framing components.
  • Sections and Construction Details
    Drawings showing deck height, framing relationships, supports, connections, and important construction conditions.
  • Connection and Attachment Details
    Structural details showing how the deck connects to the building, foundation, posts, beams, and other supporting elements.
  • Structural Calculations
    Engineering calculations supporting the framing, loads, spans, connections, and structural design.
  • Licensed Engineer Review
    Review by a licensed California engineer, with an engineering stamp provided when required by the project scope.

We’re the engineers who inspect why decks fail.


Licensed Civil Engineering Firm

DrBalcony specializes in exterior elevated structures. Our engineers understand the structural conditions, connection failures, moisture exposure, and construction deficiencies that can compromise a deck.

Designed Around the Actual Structure

Every deck design is developed around the proposed dimensions, framing, supports, attachment conditions, and property-specific requirements.

Independent Engineering Guidance

We provide design and engineering services without tying our recommendations to a construction sale. The plans are based on the needs of the structure and project.

Trusted by Property Owners Across California

Frequently Asked Questions

What types of decks can DrBalcony design?

DrBalcony designs new, replacement, expanded, and modified decks for residential and multifamily properties. Projects may include attached decks, freestanding decks, second-story decks, rooftop decks, hillside decks, and other elevated structures.

Can you design a replacement for an existing deck?

Yes. We can prepare plans for the complete replacement or reconstruction of an existing deck. The design can account for the proposed dimensions, structural configuration, support conditions, connections, and relationship to the existing building.

Can you design an addition or expansion to my deck?

Yes. DrBalcony can evaluate the proposed expansion and prepare plans showing how the new construction should be framed, supported, and connected. The existing structure may need to be reviewed before it can be incorporated into the design.

What information do you need to design my deck?

The required information depends on the project. We may request property photographs, approximate dimensions, sketches, existing plans, information about the building, and details about the proposed deck. Our team will tell you what is needed after reviewing your quote request.

Will the plans include structural calculations?

Yes. When structural engineering is included in the project scope, the design package includes calculations supporting the framing, loads, spans, supports, and connections shown in the plans.

Are the deck plans stamped by an engineer?

Plans are reviewed by licensed California engineers, and an engineering stamp is provided when required by the project scope. We will confirm the applicable deliverables in your proposal.

Can contractors use the plans to prepare bids?

Yes. The completed design package provides contractors with a defined structural scope that can be used to prepare more informed construction estimates. Contractors remain responsible for verifying field conditions and developing their own means, methods, sequencing, and final pricing.

Can the plans be used for a permit application?

The completed deck design can support permit preparation when a permit is required. Permit submission, application management, agency coordination, and plan-check administration are separate from the core design service unless specifically included in your proposal.

How long does deck design take?

Most deck designs are completed within 5–10 business days after DrBalcony receives the required project information. Larger or more complex projects may require additional time.

Do you provide deck design services throughout California?

Yes. DrBalcony serves property owners throughout California. Enter the project city in the quote form, and our team will confirm service availability and project requirements.

Can you design a deck and pergola together?

Yes. If the project includes both a deck and a pergola or patio cover, describe both structures in the quote request. DrBalcony can review whether they should be designed as one coordinated project.
