A pre-drywall inspection is a visual inspection performed during new home construction after applicable framing and rough-in work has been completed but before insulation and drywall conceal the interior construction.

At this stage, portions of the home's structure and building systems may be significantly more accessible than they will be after completion.

Depending on the construction stage, design, and accessibility, the inspection may include visual observations of accessible and observable conditions such as:

• Wall framing
• Ceiling framing
• Floor framing
• Roof and attic framing
• Headers, beams, and posts
• Studs and joists
• Visible structural connections
• Exterior wall sheathing
• Windows and doors
• Visible flashing and weather-resistant details
• Plumbing rough-ins
• Electrical rough-ins
• HVAC ductwork
• Accessible HVAC components
• Visible fireblocking and draft-stopping
• Exterior penetrations
• Attic ventilation components, when visible and accessible
• Other accessible construction components

The exact components available for inspection depend on the construction stage, what has been installed or concealed, accessibility, and site conditions. The inspection is limited to visible and accessible conditions at the time of the inspection and does not constitute structural engineering, code-compliance certification, or verification that construction fully complies with plans, specifications, manufacturer requirements, or contractual requirements.

Once drywall is installed, many construction components can no longer be visually observed without removing finished materials.

A pre-drywall inspection provides an opportunity to observe readily accessible and visible conditions before portions of the construction become concealed.

Potential concerns may include:

• Damaged framing or other materials
• Missing or incomplete components
• Observed framing conditions that may warrant correction
• Observable concerns involving headers, beams, posts, studs, joists, or other structural components
• Plumbing rough-in conditions
• Electrical rough-in conditions
• HVAC ductwork and accessible HVAC components
• Window and door installation conditions
• Visible flashing and exterior weather-resistant details
• Exterior sheathing and penetrations
• Visible firestopping or draft-stopping conditions, where accessible
• Other observable conditions within the scope of the inspection

The inspection is intended to identify observable material defects and other conditions that may warrant correction or further evaluation. The inspection does not identify every defect or predict future conditions.

Framing provides much of the structural framework of the home. During the Phase Two inspection, Frontline observes readily accessible framing components and related construction conditions.

Depending on accessibility, observations may include:

• Studs
• King and jack studs
• Wall openings
• Headers
• Posts
• Beams
• Framing connections
• Blocking
• Bracing
• Damaged or modified framing
• Other readily accessible framing components

The inspection does not determine the adequacy of the structural system, structural design, engineering calculations, or structural load requirements.

The inspection may include readily accessible:

• Floor joists
• Ceiling joists
• Beams
• Posts
• Blocking
• Visible connections
• Other accessible structural components

The inspection is visual and does not constitute structural engineering or certification of structural adequacy.

Where readily accessible and safe to observe, the inspection may include:

• Rafters
• Trusses
• Roof framing
• Bracing
• Visible connections
• Damaged or modified members
• Other accessible roof and attic components

The inspection does not include engineering analysis or certification of the roof structure.

Plumbing components may be installed within walls, floors, and ceilings before drywall.

Where readily accessible, the inspection may include observations of:

• Visible water-supply piping
• Drain, waste, and vent piping
• Pipe penetrations
• Visible pipe supports
• Accessible plumbing components
• Observable leaks or damage
• Other readily accessible plumbing conditions

The inspection is visual and is not a technically exhaustive plumbing inspection. It does not determine plumbing-code compliance, water quality, exact flow rates, pressure, or the adequacy or design of plumbing systems.

Electrical wiring and components may become concealed after drywall installation.

Where readily accessible, the inspection may include observations of:

• Visible electrical wiring
• Electrical boxes
• Wiring penetrations
• Visible cable protection
• Accessible connections and components
• Visible damage
• Other readily accessible electrical components within the scope of the inspection

The inspection does not constitute a technically exhaustive electrical inspection or certification of electrical-code compliance. Conditions requiring specialized electrical evaluation may be recommended for review by an appropriately qualified electrical professional.

HVAC ductwork and other components may be installed before drywall.

Where readily accessible, the inspection may include observations of:

• Supply and return ductwork
• Duct connections
• Duct supports
• Visible damage
• Accessible condensate piping
• Visible refrigerant-line components
• Accessible HVAC equipment
• Supply and return locations
• Other readily accessible HVAC components

Where systems are operational and conditions are appropriate for safe operation, applicable heating and cooling systems may be evaluated using normal operating controls in accordance with the applicable inspection scope.

The inspection does not include HVAC commissioning, balancing, engineering analysis, refrigerant testing, or specialized performance testing.

The pre-drywall stage may provide an opportunity to observe portions of the exterior and building envelope before interior finishes conceal related construction.

Where readily accessible, the inspection may include observations of:

• Windows
• Exterior doors
• Exterior wall-covering materials
• Exterior wall sheathing
• Visible flashing and trim
• Weather-resistant materials
• Visible sealants
• Exterior penetrations
• Other accessible exterior components

The inspection does not determine the future watertightness of the building envelope and does not guarantee that concealed or latent defects are absent.

 Where visible and readily accessible, Frontline may observe firestopping, fireblocking, draft-stopping, and related construction conditions.

Because portions of these components may become concealed as construction progresses, the pre-drywall stage may provide an opportunity to document visible conditions before access is restricted.

The inspection does not constitute a comprehensive building-code or fire-code compliance inspection.

The objective of the inspection is to identify observable material defects and other conditions that may warrant correction or further evaluation before construction progresses.

Timing is important.

InterNACHI describes a pre-drywall inspection as occurring after applicable foundation, framework, roofing, exterior covering, doors, windows, mechanical, plumbing, and electrical work has been installed and before insulation and interior walls and ceilings are covered.

Frontline recommends coordinating the inspection with the builder or construction manager so applicable components remain readily accessible.

Ideally, schedule the inspection before:

• Drywall is installed
• Interior walls and ceilings are covered
• Construction significantly restricts access to framing and rough-ins
• Other materials conceal components that would otherwise be readily accessible

If insulation has already been installed, portions of the construction may still be observable; however, insulation can restrict visibility and access to underlying components. InterNACHI's materials recognize that a pre-drywall inspection may occur after insulation is installed, while noting that insulation may conceal components.

Frontline's new construction inspection process can evaluate the home at multiple stages of construction.

Before concrete is poured

The inspection focuses on accessible foundation preparation, forms, reinforcing components, penetrations, and other applicable pre-pour conditions.

After applicable rough-in and framing work and before interior walls and ceilings are covered

The inspection focuses on readily accessible structural, exterior, mechanical, plumbing, electrical, and other applicable components within the inspection scope.

After substantial completion

The inspection evaluates applicable accessible building systems and components and identifies observable material defects, incomplete work, damage, safety concerns, and other conditions present at the time of inspection.

Each construction stage provides access to different components.

A condition that is visible during framing may become concealed after insulation or drywall is installed. Likewise, certain completed systems can only be evaluated once the home is substantially complete and the applicable systems can be operated using normal operating controls.

For homeowners seeking broader visual coverage throughout construction, Phase One, Phase Two, and Final inspections can complement one another.

The Texas Real Estate Commission's Standards of Practice establish requirements for a standard real estate inspection of an applicable substantially completed residential property.

A pre-drywall home is generally not substantially completed.

TREC rules separately recognize quality-control construction inspections of new homes, including phased construction inspections. A pre-drywall inspection is therefore a construction-phase quality-control service, rather than a standard TREC inspection of a substantially completed home.

Frontline Inspections, PLLC performs Phase Two pre-drywall inspections as independent quality-control construction inspections of new homes.

The service is performed by a Texas-licensed professional inspector using applicable professional inspection practices, including applicable InterNACHI inspection practices, while taking into account the requirements applicable to the type and stage of inspection being performed.

The Phase Two inspection is not represented as a standard TREC SOP inspection of a substantially completed home.

Frontline Inspections utilizes the InterNACHI Pre-Drywall Inspection Standards of Practice where applicable to the service being performed.

InterNACHI defines a pre-drywall inspection as a non-invasive, visual examination of accessible areas intended to identify material defects within the systems and components addressed by its Standards of Practice. The inspection is based on observations made on the date of inspection and is not a prediction of future conditions.

The inspection is limited to readily accessible installed systems and components within the applicable inspection scope. InterNACHI's SOP does not require the inspector to determine code or regulatory compliance, manufacturer installation conformance, engineering matters, or the adequacy of structural systems.

A Phase Two pre-drywall inspection is not:

• A structural engineering inspection
• An architectural inspection
• A geotechnical investigation
• A technically exhaustive inspection
• A destructive inspection
• A comprehensive building-code inspection
• A certification of structural adequacy
• A certification of complete code compliance
• A certification that construction complies with every plan or specification
• A determination of manufacturer installation compliance
• A warranty or guarantee
• A guarantee that concealed or latent defects do not exist
• A substitute for required municipal inspections
• A substitute for the builder's quality-control process

The inspection does not require the inspector to dismantle, open, uncover, or remove materials or components to expose concealed conditions. The inspector is also not required to enter areas that are unsafe or not readily accessible.

Construction changes rapidly. If insulation, drywall, finishes, equipment, or other materials have already been installed, portions of the construction may no longer be readily accessible. Frontline cannot report on conditions that cannot be visually observed or safely accessed at the time of inspection. For this reason, homeowners should coordinate the inspection with the builder so the inspection occurs while applicable components remain readily accessible.

The builder and applicable contractors remain responsible for:

• Proper construction
• Workmanship
• Construction documents
• Applicable codes and regulations
• Manufacturer installation requirements
• Completing contracted work
• Required inspections
• Correcting deficiencies

An independent inspection does not transfer those responsibilities to Frontline Inspections. The purpose of the inspection is to provide the homeowner with an independent evaluation and documentation of observable conditions within the applicable inspection scope.

Following the inspection, Frontline Inspections provides a written report documenting applicable observations and identified material defects within the inspection scope.

Photographs may be included to illustrate reported conditions and their locations.

When appropriate, the report may recommend:

• Builder review
• Correction by the appropriate contractor
• Additional investigation
• Structural engineering evaluation
• Electrical evaluation
• Plumbing evaluation
• HVAC evaluation
• Building-envelope evaluation
• Other specialized professional evaluation

The report provides the homeowner with information that can be communicated to the builder while construction is still underway.

Frontline Inspections, PLLC provides independent residential and commercial property inspection services throughout Houston and the Greater Houston Area.

As a veteran-owned and operated professional inspection company, Frontline's goal is to provide clients with clear, professional information about observable property conditions.

With new construction, timing matters.

A pre-drywall inspection provides an opportunity to observe accessible construction before important components become concealed behind insulation, drywall, and other finished materials.
