What is Residential One and Two Family Dwellings - Room Addition – Dallas, TX?
The Residential One and Two Family Dwellings - Room Addition checklist is the City of Dallas Development Services Department list of documents that go with a permit application to add onto a one- or two-family home.
On the PDF it is titled Addition to One- and Two-Family Dwellings, Application Checklist and Required Documents and runs two pages, with the date 4/21/2025 printed in the footer. Page 1 has five numbered items, each with a box to check:
- Compliance with the Energy Code and the Green Building Ordinance, shown through third-party provider documents.
- A certified county plat.
- A copy of a site plan.
- Copies of fully dimensioned building plans.
- Compliance with the EPA Lead; Renovation, Repair and Painting Program Rule, 40 CFR, Part 745.
Page 2 lists additional requirements: Conservation District and Historic Overlay District approvals for exterior work, the rule that permits go only to a registered contractor, the form board survey before foundation inspection, and the Energy Code Compliance Certificate before final inspection.
The checklist says it is not meant to cover every issue that may arise, only the more common ones, and that additional information may be needed before the permit is issued. It lists documents; it is not the permit itself.
Who needs to file Residential One and Two Family Dwellings - Room Addition – Dallas, TX?
The people who use this checklist are those preparing a permit application for an addition to a one- or two-family dwelling in the City of Dallas, so that the application package matches what the Development Services Department asks for.
Conditions the checklist attaches to specific cases:
- Registered contractors. Permits may only be issued to a registered contractor with the proper licenses and/or other credentials.
- Second-story additions to an existing single-story dwelling need an engineer's letter confirming that the foundation and first-floor framing can support the second story.
- Projects in a Conservation District that affect the exterior (walls, windows, doors, roof, etc.) need a Conservation District (CD) Work Review Form attached to the application.
- Projects in a Historic Overlay District that affect the exterior need a Certificate of Appropriateness (C of A) issued by the Landmark Commission first.
- Projects with new drive approaches must show them on the site plan.
The checklist does not name who may sign or file on behalf of an owner. Questions can go to the department at (214) 948-4480.
When to file Residential One and Two Family Dwellings - Room Addition – Dallas, TX
Use this checklist when you prepare the permit application for the addition, because the department cannot accept incomplete applications or illegible construction documents. The checklist sets no calendar deadline of its own; it lists what must be ready, and when.
Timing rules it prints:
- A Conservation District (CD) Work Review Form must first be completed and attached to the building permit application.
- A Certificate of Appropriateness must first be issued by the Landmark Commission for exterior work in a Historic Overlay District.
- A form board survey is required before the foundation inspection and goes to the building inspector.
- For permit applications on or after September 1, 2016, the Energy Code Compliance Certificate must be submitted before the building final inspection.
