a
accent lighting
Lighting used to highlight a specific feature, like artwork, an architectural detail, or a built-in. It adds depth to a room without being the main light source.
ada (americans with disabilities act)
A federal law that sets minimum standards for accessible design. In residential construction, it is most relevant for doorways, bathrooms, and ramps if someone in the household has mobility needs.
Addendum
A written update to your contract or drawings that changes something already agreed to. Every addendum should be signed by both parties before work continues.
allowance
A placeholder dollar amount in your contract for something that has not been selected yet, like tile, fixtures, or lighting. It is not extra money. If your selections cost more than the allowance, you pay the difference.
Low allowances are one of the most common ways contractors win bids. Research actual costs before you sign.
ambient Lighting
The general, overall light in a room, usually from ceiling fixtures or recessed cans. It sets the baseline brightness before you layer in task or accent lighting.
Architectural Drawings
The full set of technical drawings that describe your project, including floor plans, elevations, sections, and more. These are what your contractor builds from and what permits get reviewed against.
as-built drawings
Updated drawings that reflect what was actually built, not what was originally planned. Get these at the end of any major project. You will want them for future renovations or if you ever sell.
B
bearing wall
A wall that carries structural load from above and transfers it to the foundation. You cannot remove a bearing wall without adding a beam and new support. Always confirm with a structural engineer before demo.
Bid
A contractor's written proposal for the cost of your project. A real bid includes scope, materials, labor, exclusions, allowances, and a payment schedule, not just a total number.
The lowest bid is almost never the best bid. Compare what is actually included, not just the bottom line.
Blue Tape Walk
A walkthrough near the end of construction where you flag incomplete or incorrect items with blue painter's tape so the crew knows what needs attention before final payment.
Budget
Your total financial plan for the project, including hard costs, soft costs, and a contingency buffer. A real budget accounts for every category, not just the construction contract number.
Building Codes
The minimum legal standards for how a structure must be built, covering things like structural integrity, fire safety, electrical, and plumbing. Your contractor is responsible for building to code, but you should know they exist.
Building Permit
Official approval from your local government to proceed with construction or renovation. Pulling a permit means an inspector will verify the work meets code. Never let a contractor talk you out of pulling one.
Unpermitted work can complicate home sales and insurance claims.
C
Cabinetry
The built-in storage units in your kitchen, bathrooms, or other rooms. Cabinets are one of the highest-cost and highest-impact selections in a renovation. Stock, semi-custom, and custom are three very different price and quality tiers.
Certificate of insurance
A document proving your contractor carries the right insurance coverage, including general liability and workers comp at minimum. Always request this before anyone sets foot on your property.
Certificate of occupancy
An official document from your local building department confirming the space has been inspected and is legally safe to occupy. Required before you can move in after a new build or major renovation.
Change order
A written document that officially records any change to your project's scope, cost, or schedule. If something changes, it goes in writing. Every single time.
Verbal agreements do not protect you. If it is not in a signed change order, it does not exist contractually.
Clearances
The required minimum distances between fixtures, appliances, or walls, as specified by building code. Common in bathrooms and kitchens. Your designer or contractor should be checking these before anything gets ordered or installed.
Closeout documents
The paperwork package you receive at the end of a project: warranties, manuals, final lien waivers, permit sign-offs, and as-built drawings. Do not release final payment until you have these in hand.
COM (Customer's Own Material)
When you supply your own fabric or material for a furniture piece or upholstery item instead of selecting from the manufacturer's standard options. Usually requires a COM yardage spec from the vendor.
Concept development
The earliest design phase where direction, mood, and big-picture decisions are explored before any drawings are finalized or products are specified. Think vision boards, reference images, and overall feel.
Conditional lien waiver
A document where a contractor or subcontractor waives their right to file a lien against your property, but only once payment actually clears. This is the version to request with every payment.
Construction administration
The phase where your architect or designer stays involved during construction, reviewing submittals, answering contractor questions, visiting the site, and making sure what gets built matches the drawings.
Construction documents
The full, final set of drawings and specifications that describe every detail of what is being built. These are what permits get pulled from and what contractors price their bids against.
Construction loan
A short-term loan that funds your project while it is being built, released in draws as work is completed. It typically converts to a regular mortgage when the project is finished.
Construction schedule
A timeline showing when each phase of work is planned to start and finish. Get one from your contractor before work begins and review it regularly. It is your main tool for spotting delays before they compound.
Contingency
A budget buffer set aside for unexpected costs. Not a slush fund, but a planned reserve for real unknowns. New builds typically need 10 to 15 percent; renovations with older structures often need more.
If your contractor is managing the contingency, make sure your contract specifies that unused funds come back to you.
Contract
The legally binding agreement between you and your contractor. A complete contract covers scope, schedule, payment terms, change order process, and what happens if something goes wrong. If any of those are missing, ask before signing.
Cost-plus contract
A contract structure where you pay the actual cost of labor and materials plus a percentage fee for the contractor. Transparent in theory, open-ended in practice. Without a not-to-exceed clause, there is no budget ceiling.
If you are signing a cost-plus agreement, negotiate a budget cap and require regular cost reporting.
d
Daily Logs
Written records your contractor keeps of what happened on site each day, including crew, weather, work completed, and any issues. A good contractor maintains these automatically. They are useful if a dispute ever comes up.
Demo Plan
A drawing that specifically shows what is being removed or demolished before new construction begins. It confirms scope, protects adjacent areas, and helps catch surprises like a bearing wall that was assumed non-structural.
Design Development
The phase where conceptual ideas get refined into specific decisions, including actual products, dimensions, materials, and finishes. This is where things stop being flexible and start costing real money.
Design Phases
The stages a design project moves through, typically schematic design, design development, and construction documents. Each phase gets more detailed and more locked. Changes get more expensive the later you make them.
Details
Zoomed-in drawings showing how specific conditions are built, like a custom millwork connection, a tile transition, or a tricky structural junction. They translate design intent into buildable instructions.
Draw Schedule
The agreed-upon payment timeline tied to project milestones. You release funds as work is completed and verified, not on a calendar or at a contractor's request. Never pay ahead of work.
Drywall
The wall and ceiling material, also called gypsum board or sheetrock, that gets installed after framing and rough-in work. Its installation typically signals the end of the messy phase of construction.
e
Egress
A required exit point from a space, such as windows in bedrooms or doors in basements. Building code mandates minimum egress sizes so people can escape in an emergency. Non-compliant egress can hold up your certificate of occupancy.
Electrical Plans
Drawings showing the location of outlets, switches, fixtures, and panel connections. Review these carefully before walls close. Moving an outlet after drywall is a change order.
Elevations
Drawings that show the vertical face of a wall, interior or exterior, as if you were standing directly in front of it. Used to show cabinet layouts, tile patterns, window placement, and millwork.
F
FF&E (Furniture, Fixtures, and Equipment)
The movable items in your space that are not permanently attached to the structure, including furniture, light fixtures, rugs, and window treatments. Often managed separately from the construction contract and easy to underbudget.
Field order
A directive that changes something on site during construction, usually issued by an architect or designer to the contractor. Similar to a change order but typically used for minor clarifications rather than cost changes.
Final completion
The point where all work, including punch list items, is fully done, all documents are delivered, and final payment is released. This is different from substantial completion, which just means the space is usable.
Finish Carpentry
The detail woodwork installed after drywall, including baseboards, door casings, crown molding, and built-ins. It is one of the last trades on site and one of the first things people notice. Quality varies widely.
Finish Plan
A drawing or schedule that maps out every finish selection by room and surface, including flooring, wall material, tile, and paint. Keeps selections organized and ensures nothing gets missed before ordering.
Finishes
Every surface material in your space, including paint, tile, flooring, countertops, cabinetry, and hardware. Finishes are where most homeowners make selections without understanding the sequencing, which leads to things not working together or arriving too late.
Fixed-Price Contract
A contract where you agree on a total price before work begins. The number only stays fixed if the scope is clearly defined. Vague scope plus a fixed price equals change orders that reopen the budget.
Fixed-price feels safe but only protects you if every scope item is spelled out in detail.
Flashing
Metal or waterproof material installed at joints and transitions, such as around windows, where a roof meets a wall, or at chimneys. Flashing failures are one of the most common sources of water damage.
Floor Plan
A drawing showing your space from above, including room layout, walls, doors, windows, and dimensions. The most commonly referenced drawing in any project and the basis for everything else.
Framing
The structural skeleton of a building, made up of wood or metal members that form walls, floors, and the roof. Framing happens early and sets the dimensions of every space. Changes after framing are expensive.
Furniture Plan
A floor plan that shows where furniture will be placed in a room. It confirms that your space will actually function in terms of traffic flow, clearances, and scale, before you buy anything.
g
General contractor (GC)
The professional responsible for managing your construction project from start to finish, including hiring and coordinating subcontractors, pulling permits, and delivering the completed work. Your contract is with them and they are accountable for everyone they bring on.
Guaranteed maximum price (GMP)
A contract where the total price is capped at an agreed ceiling. If the project comes in under that cap, savings can be shared. It gives you the transparency of cost-plus with a built-in budget limit.
H
Hard Costs
The direct construction costs, including labor, materials, subcontractors, and site work. The number your contractor quotes is mostly hard costs. It is typically the largest portion of your budget but not the only portion.
HVAC
Heating, ventilation, and air conditioning. One of the most expensive and least visible systems in your home. Duct routing decisions made during design directly affect ceiling heights, closet sizes, and construction cost.
i
Initial Consultation
The first meeting between a homeowner and a designer or contractor. Its purpose is to assess fit, understand the project scope, and determine whether to move forward together. Come prepared with your budget range and project goals.
International Building Code (IBC)
A model building code that most US jurisdictions have adopted, setting baseline standards for structural, fire, and life safety requirements. Your local code may have amendments, but IBC is the common starting point.
Invoice Approval Process
The system for reviewing and approving contractor invoices before releasing payment. Having a clear process, including who reviews, what documentation is required, and what the timeline is, prevents disputes and keeps your cash flow controlled.
L
Lead Time
How long it takes for a product to be manufactured and delivered after it is ordered. Cabinets, tile, plumbing fixtures, and custom furniture all have lead times, some measured in weeks and some in months. Order late and you delay your project.
Letter of Engagement
A preliminary agreement between you and a designer or architect that defines the scope of work, fee structure, and project expectations before a full contract is signed. Treat it like a contract because it often is one.
Lien
A legal claim filed against your property by a contractor, subcontractor, or supplier who was not paid for work they performed. A lien can prevent you from selling or refinancing your home until it is resolved, even if you paid your general contractor in full.
You can be subject to a lien even if you never had a direct relationship with the person who filed it.
Lighting Design
The intentional planning of how a space will be lit, combining ambient, task, and accent sources to create function and atmosphere. Lighting is often the last thing planned and the first thing that shows when it was not.
M
Markup
The percentage a contractor adds to the cost of labor, materials, and subcontractors to cover overhead and profit. It is a legitimate part of how contractors get paid. What matters is that it is clearly defined in your contract.
Undefined markup is one of the most common sources of end-of-project billing disputes.
Mechanic's Lien
A specific type of lien filed by someone who provided labor or materials to improve your property and was not paid. It attaches to the property itself, not to a person, meaning it follows the home, not the contractor.
Milestone Payments
Payments tied to specific project completions, such as foundation poured, framing done, or drywall complete, rather than a calendar date. This is the structure you want. It keeps your money aligned with actual progress.
Millwork
Custom wood products built for a specific installation, including built-in shelving, paneling, custom cabinetry, and wainscoting. Millwork is produced off-site in a shop and installed once construction is further along. Lead times matter.
Mockup
A sample of how a finish will actually look in your specific space, such as a section of tile installed on the wall or a paint color on the actual surface. Always worth doing for anything you are uncertain about before committing to full installation.
N
Notice of Delay
A written notice from your contractor informing you that the project schedule will be impacted and why. Legitimate delays happen. What matters is that they are documented in writing, not mentioned in passing.
Notice to Proceed
Your written authorization telling the contractor they are cleared to begin work. This is the official start of the construction clock, including the schedule and any timeline-based warranties.
O
Owner-Architect Agreement
The contract between you and your architect defining their scope of services, fee structure, and responsibilities across each design phase. Standard AIA agreements are widely used as the starting point.
P
Phase Inspection
An inspection conducted at a specific stage of construction, such as framing, rough-in, or pre-drywall, to verify work meets code before it gets covered up. For new construction, these are your best chance to catch issues while they are still fixable without major cost.
Pre-Construction Meeting
A formal kickoff meeting before work begins to align your contractor, subcontractors, and design team on schedule, sequencing, communication protocols, and site logistics. Missing this meeting is a setup for miscommunication later.
Preliminary Notice
A document some contractors and suppliers are required to send early in a project to preserve their right to file a lien later. Receiving one is not an accusation. It is a standard legal step in many states. Keep a record of everyone who sends one.
Procurement
The process of sourcing, ordering, tracking, and receiving all the products and materials going into your project. Poor procurement is one of the most common causes of construction delays.
Punch List
The written list of incomplete or unsatisfactory items that need to be addressed before your project is truly finished. You create it and you own it. It is your leverage to hold final payment until everything is right.
Punch Walk
The walkthrough where you and your contractor go through the space together to document everything still needing attention. Do this yourself. Do not rely on the contractor to write their own punch list.
Purchase Orders
Written orders issued to vendors or subcontractors that confirm what is being ordered, at what price, and when it is expected. They create a paper trail that protects you if something arrives wrong, late, or not at all.
R
Reflected Ceiling Plan
A drawing that shows your ceiling as if you were looking straight down at a mirror, depicting lighting placement, soffits, beams, and mechanical elements above. Essential for coordinating lighting and HVAC before walls and ceilings are finished.
Request for Information (RFI)
A formal question submitted by your contractor to the designer or architect when something in the drawings is unclear or missing. Every RFI should be answered in writing. Those responses become part of the project record.
Request for Proposal (RFP)
A formal document you send to multiple contractors asking them to submit bids for your project. A well-written RFP defines scope clearly enough that all bids are comparing the same thing.
Request for Qualifications (RFQ)
A document you send to contractors or designers asking them to demonstrate their experience and qualifications before you invite them to bid. Used to narrow a long list to a short one worth pursuing.
Retainage
A percentage of each payment you hold back until the project reaches substantial completion, typically 5 to 10 percent. It keeps the contractor financially motivated to finish. Make sure it is defined in your contract.
Roof Plan
A drawing showing the roof from above, including slopes, ridgelines, valleys, and drain locations. Important for coordination with gutters, HVAC equipment, and any rooftop features.
Rough-in
The phase where mechanical, electrical, and plumbing systems are installed inside walls and floors before they are covered. This is when pipes, wires, and ducts get placed in their permanent locations. Changes after rough-in are expensive.
s
Schematic Design
The first formal design phase where your architect or designer translates your goals into an initial layout and concept. Drawings are rough. The point is to test ideas and confirm direction before investing in details.
Scope of Work
The written description of exactly what your contractor is responsible for building or completing. The more specific, the better. Anything not in the scope is not in the price.
Sections
Drawings that show a slice through a building, like a cutaway view, to reveal height relationships, structural conditions, and how different elements connect vertically. Most useful for understanding complex conditions that drawings cannot fully capture from above.
Shop Drawings
Detailed drawings produced by a fabricator or subcontractor showing exactly how something will be built or installed, such as custom cabinets or structural steel. They require review and approval before fabrication begins.
Site
The physical location of your project and all the conditions, logistics, and responsibilities that come with it. Understanding site conditions early, including access, utilities, soil, and existing structure, prevents expensive surprises later.
Site Plan
A drawing showing your property from above, including the building footprint, setbacks, driveway, utilities, and relationship to property lines. Required for most permit applications.
Site Walkthrough
A visit to the project location before, during, or after construction to assess conditions, verify progress, or document completion. Get in the habit of regular walkthroughs and take photos every time.
Soft Costs
All the project costs that are not direct construction, including design fees, permits, engineering, inspections, financing, insurance, and temporary utilities. Often 15 to 25 percent of total project cost. Most homeowners forget to budget for these until the invoices arrive.
Do not build a budget based only on the construction contract number.
Specifications
Written documents that define the exact standards, materials, and methods to be used in construction. Where drawings show what to build, specifications describe exactly how and with what.
Specifications Schedule
A chart or table that organizes specification information by room or element, making it easier to cross-reference finish and material selections across the full project.
Submittal
Product samples, shop drawings, or data sheets submitted by the contractor for review and approval before installation. The approval process exists to catch problems before they are permanent.
Submittal Log
A running list tracking every submittal, including what was sent, when, review status, and whether it was approved or rejected. Without a log, submittals fall through the cracks and installations proceed without proper review.
Subcontractor
A specialist hired by your general contractor to perform a specific scope of work, such as electrical, plumbing, tile, or framing. You have no direct contract with them. Your GC is responsible for their work and their payment.
Substantial Completion
The point at which a project is far enough along that the space can be used for its intended purpose, even if minor items remain. It triggers the punch list process, the warranty clock, and usually the release of most remaining payment.
T
Task Lighting
Lighting directed at a specific work area, such as under-cabinet lights in a kitchen, a lamp over a desk, or vanity lights in a bathroom. Task lighting serves function first. It is not decorative.
Time and Materials Contract
A contract where you pay the actual hourly labor rates and material costs as the project unfolds. There is no fixed total. Appropriate for exploratory or undefined scope, but without a budget cap, costs are open-ended.
If you are signing a time and materials contract, negotiate a not-to-exceed number and require weekly cost reporting.
U
Unconditional Lien Waiver
A document where a contractor or subcontractor permanently waives their right to file a lien, whether or not payment has cleared. Only appropriate to sign once a check has actually been deposited and cleared.
V
Value Engineering
The process of finding ways to reduce cost without significantly reducing the result, such as swapping materials, simplifying details, or resequencing work. When done with you in the room, it is a tool. When done without you, it can change what you are getting.
W
Warranty
A contractor's written commitment to stand behind their work for a defined period, typically one year for workmanship. Know what yours covers, when it starts, and how to submit a claim.
z
Zoning
Local regulations that govern what can be built where, including setbacks, building height, allowable uses, and lot coverage. What zoning allows on your property determines what you can legally build before any design work begins.
