Ground-level patio on a 9,375 sq ft demo lot — aerial

Decks & patios · DECK 07

Ground-level patio

Poured on grade, nothing framed. The cheapest way to get the same room.

01

One sheet, from one model

These are not separate drawings kept in step by hand. They are projections of the same model, so a change to the model changes all of them at once. A proposal with no interior has nothing to elevate or section — so the engine produces one sheet and does not pad the set.

02

Why this passes — and what sends one back

  1. Setbacks measured to the new edge, not to the house — 29.5′ to the nearer side line here.
  2. The scale is written down (1″ = 20′), not left to be inferred from the page size.
  3. North arrow on the sheet.
  4. Existing dashed, proposed solid. This is the first thing read at the counter, and getting it backwards is a refusal on its own.
  5. The coverage arithmetic is shown, not just its result — 1,873 sq ft existing and nothing added, so coverage does not move.

What sends this one back

Setbacks measured to the house instead of the deck

The distance that matters runs from the property line to the deck’s outermost edge — stairs and landings included. A plan that measures to the house wall reads compliant and is not, and the reviewer scales the drawing to check.

What the sky can’t see — you add these

  • A recorded easement along the rear line — platforms sit on top of them constantly
  • The eave line, where the deck tucks under the existing roof
  • On unsewered lots: the septic tank and leach field the footings must stay clear of

provide them and they go on the sheet · invented lines never do

Same lot, 8 ways

Every deck in this category is drawn on the identical lot, so the coverage numbers on the cards can be read against each other.

What this is not

This page is a demonstration our engine drew — not a permit that was submitted and not a drawing that was approved. Structural calculations and Title 24 energy compliance have to be signed by a licensed engineer or a certified analyst: we hand those off and we do not stamp them. Decks and small wood structures mostly fall inside the prescriptive tables and need no stamp at all, which is why they are the cleanest category here.
