Nevada Interior Designer seal requirements: proper sizing, signing and sealing of documents
As of
Nevada registers interior designers under NRS Chapter 623 and gives them a seal unlike any circle: NAC 623.755(1) requires an equilateral triangle with 2 1/2 inch sides bearing the registrant's name and registration number, and NRS 623.185(1) adds the legend "Registered Interior Designer." Embossed, rubber-stamp and electronic seals are all permitted, and every plan, specification, report or other document issued for official use must be signed, sealed and dated.

NAC 625.610 was not touched by the board's 2024-2025 rulemaking, LCB File R007-24, which amended the professional land surveyor standards of practice at NAC 625.655 and 625.666. Do not confuse NAC 623.175, which describes the Board's own seal as two concentric circles of about 1 1/2 and 1 7/8 inches, with the registrant's seal in NAC 623.755.

Nevada interior designer seal questions
Is the Nevada interior designer's seal a circle?▾
Nevada's registered interior designer seal is an equilateral triangle with 2 1/2 inch sides, not a circle; the circular 1 7/8 inch seal in the same rule chapter belongs to architects (NAC 623.750) and residential designers (NAC 623.760). (NAC 623.755(1)(a); NAC 623.750; NAC 623.760)
Does a Nevada interior design document need wording outside the seal?▾
Beyond the seal, NRS 623.185(4) requires every plan, drawing, specification or other document prepared by a registered interior designer to carry a statement that it was prepared by a registered interior designer registered under chapter 623. (NRS 623.185(4))
Which Nevada documents do not have to be stamped?▾
NAC 623.763(5) exempts as-built plans, record plans, bid documents, construction-progress observation reports and cost estimates from stamping, so sealing them is not required. (NAC 623.763(5))
