LEED AP ID+C
LEED AP ID+C (Interior Design and Construction)
The LEED AP ID+C (Interior Design and Construction) demonstrates advanced expertise in green interior design and construction practices for commercial interiors, retail spaces, and hospitality projects. It covers the LEED v4 ID+C rating system used for fit-outs, renovations, and tenant improvements within existing buildings — where design teams control the interior environment but not the base building systems.

LEED AP ID+C Frequently Asked Questions
What does LEED AP ID+C stand for?
LEED AP ID+C stands for LEED AP ID+C (Interior Design and Construction). It is administered by GBCI / USGBC.
Who administers the LEED AP ID+C?
The LEED AP ID+C (Interior Design and Construction) (LEED AP ID+C) is administered by GBCI / USGBC. For official information, visit the GBCI / USGBC website.
How many questions is the LEED AP ID+C?
The LEED AP ID+C consists of 100 questions. Candidates are given 2 hours to complete the exam.
What is the passing score for the LEED AP ID+C?
The passing score for the LEED AP ID+C is 170/200, as set by GBCI / USGBC. Scoring methodology and passing standards may be updated periodically. Always verify current requirements with the governing body.
How much does the LEED AP ID+C exam cost?
The LEED AP ID+C exam fee is $350 USD. This fee is set by GBCI / USGBC and may vary by testing centre, region, or membership status. Additional fees for registration or rescheduling may apply.
What types of projects use LEED ID+C?
LEED ID+C is used for tenant fit-outs and interior renovation projects: corporate offices, retail stores, restaurants, hotels/hospitality, and healthcare interiors. It is specifically designed for situations where tenants control the interior but occupy a building where the base building (structure, HVAC, envelope) is owned or controlled by another party.
How does LEED ID+C differ from LEED BD+C?
LEED BD+C applies to the entire building — new construction or major renovation — with the design team controlling all systems. LEED ID+C applies only to the interior space — the tenant or design team controls the fit-out but not the base building. LEED ID+C has fewer credit categories and the credit thresholds reflect what a tenant can realistically control.
What low-emitting materials are required for LEED ID+C?
LEED ID+C has a Low-Emitting Materials prerequisite and optional credit covering VOC content limits for: adhesives and sealants, paints and coatings, flooring, composite wood products, and ceiling and wall systems. These requirements protect occupant health by reducing volatile organic compound (VOC) emissions from interior finishes — a critical indoor environmental quality concern.
Who should get LEED AP ID+C?
LEED AP ID+C is most relevant for interior designers, space planners, tenant improvement contractors, commercial real estate professionals, and corporate real estate managers who work on office, retail, or hospitality interior projects. It is less common than BD+C but valuable for those whose practice focuses on tenant improvements and commercial interiors rather than ground-up construction.
How difficult is the LEED AP ID+C exam?
The LEED AP ID+C (Interior Design and Construction) exam is considered similarly challenging to other LEED AP specialty exams. The specialty portion tests deep knowledge of interior-specific green strategies, materials, indoor environmental quality, and commissioning for interior spaces. Pass rates are estimated in the 50–65% range for the specialty portion.
What are the eligibility requirements for LEED AP ID+C?
You must have documented project experience on a LEED-registered or certified project within three years of application, with relevance to interior design and construction scope.
How long should I prepare for the LEED AP ID+C exam?
Eight to sixteen weeks is a standard preparation window. Focus on the LEED v4 ID+C Reference Guide, understanding how credits apply to tenant improvement and fit-out projects, and practicing credit calculation scenarios.
What career value does the LEED AP ID+C provide?
LEED AP ID+C is valued for interior designers, commercial interior project managers, and space planners working on LEED-pursuing tenant projects. The credential supports LEED credit documentation and signals sustainability expertise in interior project delivery.
What is the LEED AP ID+C retake policy?
A 30-day waiting period applies after the first failure. A 90-day waiting period is required after any subsequent failure.
How long does LEED AP ID+C certification last?
LEED AP credentials are maintained over two-year reporting periods with 30 continuing education hours required (including 6 LEED-specific hours).
How does LEED AP ID+C compare to LEED AP BD+C?
ID+C is tailored for interior projects — tenant improvements, commercial interiors, retail, and hospitality fit-outs. BD+C applies to whole-building new construction and major renovation. Interior designers and commercial interiors practitioners typically pursue ID+C, while architects and MEP engineers on full building projects pursue BD+C.
