Dallas Deck Site Plan for Permit: Setbacks, Stairs and Backyard Layout

A backyard deck can create useful space for outdoor dining, relaxing and entertaining. Before settling on its size, check how the deck, stairs and landing will fit around your house and property boundaries.

A Dallas deck site plan shows the proposed layout from above. It helps explain the deck’s location, its distances from property lines, and how people will move between the house and backyard.

Does a Deck Need a Permit in Dallas?

Some small, low, detached decks may qualify for a permit exemption. However, height alone does not determine whether a deck is exempt.

The Chapter 52 booklet linked from Dallas’s Current City Code page lists the following conditions in Section 301.2.1, item 13. The deck or platform must:

• Be on property containing a single-family or duplex premises.
• Have an area of no more than 200 square feet.
• Be no more than 30 inches above grade at any point.
• Be detached from the dwelling.
• Maintain the required clearance from overhead service-drop conductors.
• Not serve the required exit door identified in the provision.

These conditions must be considered together.
[1]

For example, an attached deck does not qualify under this particular exemption simply because it is low to the ground. Ask Building Inspection to confirm the current requirements for your address and design before starting work.

Dallas also states that applicable codes must be followed on all work, including work that does not require a permit.

Check Zoning Before Choosing Deck Setbacks

A setback is the required separation between a structure and a relevant property line. Dallas describes these areas as required front, side and rear yards. Their dimensions depend on the applicable zoning and property restrictions.
[2]

Start by confirming that the property is within the City of Dallas. Next, identify its zoning district and any special overlays.

The city’s Zoning Resources page links to the City of Dallas Map Hub. This resource includes address searches, zoning information and layers for historic areas, conservation districts and other constraints.
[3]

Before finalizing the layout, ask the city:

• Which setback rules apply to the proposed deck?
• How do its height and attachment to the house affect the review?
• How should stairs, landings and projections be measured?
• Are there recorded building lines or special district requirements?

Avoid choosing a setback based on a neighbor’s deck or a generic online dimension. Confirm the rules for your property and proposal.

Include the Stairs and Landing in the Site Plan

The deck platform is only part of the backyard layout. Stairs can extend several feet beyond it, and the landing needs its own space.

Show the complete proposed arrangement, including:

• The deck’s length and width.
• The position and direction of each stair flight.
• Intermediate landings, if proposed.
• The bottom landing or connection to a path or patio.
• Relevant distances from the stairs and landing to property lines.

As a planning example, a deck might fit comfortably behind the house while stairs projecting toward the side fence create a tighter clearance. Drawing both features allows you to compare layouts before committing to construction.

The site plan shows where the stairs go. Separate construction details explain their framing, dimensions, handrails and other safety features. Dallas’s adopted residential code and local amendments provide the framework for that construction review.

Account for Deck Height and Sloping Ground

A deck may sit close to the ground beside the house but stand higher above the yard at its outer edge. Record the proposed deck level and relevant ground levels when preparing your design.

Useful information to discuss with your designer or contractor includes:

• The deck surface level relative to the adjoining doorway.
• Changes in ground level beneath and around the deck.
• The location of the stair landing.
• Existing retaining walls or raised garden beds.
• Areas where water currently collects.

If reliable elevations are required, ask which measurement source the city will accept. Do not present estimated levels as surveyed information.

What Should a Dallas Deck Site Plan Show?

Dallas’s residential addition checklist provides useful drawing conventions. Its site-plan section calls for a standard scale, dimensions, property lines, building lines, easements and structure outlines, including projections. Confirm which checklist applies to your deck project.
[5]

Clearly label existing and proposed work. If the project removes an old deck, show that change so the drawing does not suggest both decks will remain.

Check Property Lines and Easements

Use available survey and recorded property information to establish the drawing’s boundaries. An existing fence should not be assumed to follow the legal property line.

Review known easements before placing posts, footings, stairs or landings within them. Check the recorded terms and resolve any uncertain location or restriction with the appropriate professional or easement holder.

If you are unsure whether you need a new survey, read our
site plan versus survey guide.
A drafted layout uses available source information; it does not establish legal boundaries through field surveying.

Make the Backyard Layout Practical

After checking the applicable restrictions, compare layouts for everyday use.

• Keep routes clear: Leave a usable connection between the stairs, yard and side gate.
• Allow for furniture: Avoid placing the main walking route through a crowded seating area.
• Check door movement: Consider the swing and use of doors opening toward the deck.
• Preserve maintenance access: Consider nearby air-conditioning equipment, meters and exterior walls.
• Consider drainage: Plan around existing runoff paths and low spots.

The featured image illustrates these relationships. Its arrows are conceptual; they do not specify required distances or represent a property-specific permit drawing.

Prepare for the Dallas Permit Process

1. Confirm jurisdiction and zoning. Identify the authority and property rules that apply.
2. Confirm whether a permit is required. Provide the deck’s area, height, attachment details and doorway relationship.
3. Gather property documents. Locate available survey, plat and easement information.
4. Prepare the site plan. Include the deck, complete stair arrangement and placement dimensions.
5. Confirm supporting drawings. Ask about required footing, framing, connection, guardrail and stair details.
6. Submit through the current city system. Dallas’s Residential Permits page directs applicants to DallasNow for permitting services.

A clear site plan supports the application, but approval also depends on the proposed design and required supporting documents.

Frequently Asked Questions

Is every deck below 30 inches exempt from a permit?

No. Dallas’s published exemption includes conditions concerning area, attachment, overhead electrical clearance and required exit-door use. Confirm the complete rule for your proposal.

Should the stairs appear on the site plan?

Yes. Include their location and footprint, along with landings and relevant boundary distances. Leaving them out gives an incomplete picture of the proposed layout.

Does a site plan include structural deck design?

A site plan focuses on placement. Footings, framing, ledger connections, guards and stairs require construction details appropriate to the project.

What if I add a roof or pergola later?

Describe that work to the city before proceeding. A covered structure introduces additional design and review questions that an uncovered deck layout may not address.
