Code & permits
Designed to code. Drawn for permit.
Every Transom design is drawn to the building code your city enforces and delivered as a permit-ready set. Here is what that means in practice.
01 — What we check
Six things a reviewer will look for.
Compliance is not a stamp added at the end. It is a set of dimensions and notes that shape the design from the first plan.
Clearances
Walkways, work aisles, appliance doors and landing space. Dimensioned on the plan, not left to the installer.
Egress
Bedrooms and basements need a way out. Under the model residential code an escape window needs at least 5.7 sq ft of clear opening, 24 in. high and 20 in. wide, with the sill no more than 44 in. above the floor.
Safety glazing
Glass in doors, beside doors, around tubs and showers and close to the floor must be tempered or laminated. We mark every such pane.
Electrical layout
Receptacle spacing, GFCI and AFCI protection, dedicated appliance circuits and lighting controls, on a plan your electrician can price.
Plumbing layout
Fixture locations, clearances at toilets and vanities, and venting constraints flagged before the walls close.
Accessibility
Commercial interiors follow the ADA Standards: 36 in. clear routes, 60 in. turning space, reach ranges and compliant counters.
02 — The permit set
Seven sheets, one story.
A typical set. Each sheet answers a question the reviewer, the contractor or the inspector will ask.
| Sheet | Title | What it shows |
|---|---|---|
| A-001 | Cover & code summary | Project data, applicable codes and the sheet index. |
| A-101 | Existing & demolition plan | What stays and what goes, measured on site. |
| A-102 | Proposed floor plan | Dimensioned layout, clearances and door swings. |
| A-201 | Interior elevations | Every cabinet run, tile extent and pane of glass. |
| E-101 | Lighting & electrical plan | Fixtures, switching, receptacles and appliance circuits. |
| P-101 | Plumbing plan | Fixture locations with supply and drain notes. |
| A-601 | Schedules | Windows, doors, finishes, appliances and fixtures. |
03 — How a permit goes
From code check to issued permit.
- Step 01
Code check
We confirm which code editions and local amendments your jurisdiction has adopted.
- Step 02
Drawings
The design is drawn as a coordinated set, with a code summary on the cover sheet.
- Step 03
Submission
You or your contractor submit. We prepare the set and the forms the city asks for.
- Step 04
Review
We answer plan-review comments and revise sheets until the permit is issued.
04 — Plainly
What we are, and are not.
Transom is a design studio. We are not a licensed architecture or engineering firm, and we do not stamp drawings. Many residential remodels and tenant interiors do not need a stamp. Some do. If yours needs an architect or a structural engineer, we say so at the start and coordinate with one.
Codes vary by city and by edition. The figures on this page come from the model codes. Your jurisdiction’s adopted edition and local amendments govern, and the building department has the final word. We design to current code; we do not promise an inspection result.
