Permit Pathway
Get your drainage, waterproofing, and structural drawings approved as one package, no stop-and-revise cycles.
Common Approval Risks
The failure modes below are predictable, and avoidable when the submittal is built correctly from the start.
Adding underground elements to a standard house plan after initial review resets the review clock with each revision cycle.
Drainage, waterproofing membrane specs, and structural drawings are submitted together so reviewers see one complete picture.
Dallas clay soils expand when wet and shrink in drought, submitting without a soil test invites a reviewer flag and a delay.
The soil test and site survey go in with the initial package, not as a follow-up after the reviewer requests them.
Retaining wall details that do not align with the drainage plan give reviewers grounds to reject the submittal outright.
Retaining wall structural details and drainage system documentation are cross-checked before submittal so they match.
Hillside properties in the Dallas area may require geotechnical documentation that a flat-lot submittal template simply omits.
Slope and hillside lots are identified early so geotechnical documentation is prepared before Dallas Development Services requests it.
Permit Scope
An earth-sheltered permit package spans several review areas that a standard residential submittal does not address.
The site plan documents lot boundaries, below-grade footprint, and drainage outlet paths to satisfy zoning review requirements.
Roof slab drainage, sub-slab drain tile, and surface water routing are documented to show a clear path to a permitted outlet.
The membrane type, application method, and coverage area are specified in the submittal to meet below-grade code compliance review.
Stamped structural drawings for retaining and bermed walls show load calculations and reinforcement to satisfy foundation plan review.
A geotechnical report and site survey address Dallas clay soil conditions and any slope factors that affect foundation scrutiny.
Checks the design against Dallas Development Services requirements.
Organises foundation wall drawings for the plan reviewer.
Documents partially buried wall design for permit submittal.
Why Choose Us
Permit approval for a below-grade home depends on how the submittal is assembled, these are the process and accountability factors that matter.
Every enquiry receives a written review of lot slope, drainage, clay-soil movement, and permit scope before it reaches a builder.
The review knows which documentation Dallas Development Services flags on below-grade submittals and prepares for those reviews in advance.
Drainage, waterproofing, retaining wall, and structural drawings are coordinated as one package to reduce back-and-forth with reviewers.
Dallas expansive clay is noted in the site review so soil test requirements are built into the submittal from the first draft.
The site review identifies when a lot needs geotechnical documentation before Dallas Development Services requests it, avoiding mid-review delays.
The Process
01
Share the lot address, slope, and your design goals so the written site review can cover drainage, clay-soil risk, and permit scope.
02
The written site review identifies the documents required, then your enquiry goes forward for a quote on the actual permit work.
03
The unified submittal, site plan, drainage, waterproofing, and structural drawings, is prepared and filed with Dallas Development Services.
