How to Read a Renovation Estimate: Allowances, Exclusions, Change Orders and Payment Schedules (NJ & NYC)
A builder’s guide to kitchen and bathroom renovation estimates in New Jersey and NYC: line items, allowances, exclusions, contingency, change orders and payment schedules, and what NJ and NY law require in writing.
Short answer
A useful renovation estimate tells you what is included, what is excluded, which numbers are still guesses (allowances), and when you pay. Compare bids on those four things, not on the bottom line: the cheapest bid is often the one with the lowest allowances and the longest exclusion list. In New Jersey, home improvement contracts over $500 must be in writing with the work, materials, total price and start and completion dates spelled out; New York sets similar rules and requires deposits taken before substantial completion to be held in trust or bonded.
Estimate, proposal, contract: know which one you are holding
Contractors use these words loosely. An estimate or budget number is an opinion of cost, often given after one site visit and before drawings exist. A proposal is a priced scope you can accept. The contract is what binds both sides, and it should incorporate the final scope, drawings, finish selections and payment schedule. Treat anything before the contract as a working document: ask questions, ask for revisions, and make sure every answer ends up in writing.

The parts of a good estimate
A kitchen or bathroom estimate you can actually compare usually has these sections:
- Scope of work by trade or phase: protection and demolition, framing, plumbing, electrical, HVAC or ventilation, drywall or plaster, waterproofing, tile, cabinetry and millwork, countertops, painting, cleanup.
- Specified materials: the products the contractor has priced, with make and model where they are known (tub, toilet, valve, hood, cabinet line, tile).
- Allowances for items you have not chosen yet.
- Exclusions and owner-supplied items.
- General conditions: supervision, permits and filing, dumpsters or debris removal, protection of common areas, building insurance certificates.
- Overhead and profit, shown separately or built into the line items.
- Schedule and payment terms.
A one-line “kitchen renovation: $78,000” is not an estimate you can compare or hold anyone to. New Jersey’s home improvement rules require the written contract to describe the work and the principal products and materials, including make, size and model of principal fixtures where applicable (N.J.A.C. 13:45A-16.2). New York requires a specific description of the work and materials as well.
Allowances: where most budget surprises start
An allowance is a placeholder for something not yet selected: “tile material allowance $12 per sq ft”, “plumbing fixtures allowance $4,500”, “lighting fixtures allowance $2,000”. If your final choice costs more, you pay the difference; if it costs less, you should get a credit.
What to check:
- Is the allowance realistic for what you want? A $5 per sq ft tile allowance does not cover the large-format porcelain or zellige in your inspiration photos. Low allowances make a bid look cheaper and come back as change orders.
- Material only, or material and labor? Tile allowances are usually material only, but a herringbone or mosaic pattern also costs more to install. Ask how labor is adjusted.
- Is markup applied to overages? Some contractors add overhead and profit to the difference; that should be stated.
- Who orders and who handles returns and breakage?
| Typical allowance item | What it usually covers | Question to ask |
|---|---|---|
| Tile (floor and wall) | Material per sq ft, sometimes trim pieces | Does it include bullnose, metal edge trim, setting materials and waste? |
| Plumbing fixtures | Faucets, shower valve and trim, toilet, sink | Is the valve body (rough-in) included separately from the trim? |
| Lighting fixtures | Decorative pendants, sconces, vanity lights | Are recessed lights and their trims priced in the electrical line instead? |
| Countertops | Slab material and fabrication per sq ft | Are edge profiles, sink and cooktop cutouts and backsplash included? |
| Cabinet hardware | Pulls and knobs | Per piece or a lump sum? Installation included? |
The fewer allowances left open when you sign, the more reliable the contract price. Choosing tile, fixtures and stone before signing is the single best way to protect a budget.
Exclusions and owner-supplied items
Read the exclusions line by line. Common ones in NJ and NYC kitchen and bathroom work:
- Appliances (often owner-supplied), and their delivery and haul-away.
- Architect, engineer or expediter fees, and in NYC co-ops and condos, the building’s review, deposit and insurance requirements.
- Asbestos testing and abatement, and lead-safe work beyond what the contractor normally includes. In New York City, buildings built before 1987 commonly need an asbestos assessment before a DOB permit is issued.
- Hidden conditions: rotted subfloor, undersized joists, failing cast-iron or galvanized pipe, outdated wiring found when walls open.
- Electrical service or panel upgrades, gas line upsizing, and utility company work.
- Painting outside the renovated room, and patching adjacent rooms.
- Window treatments, furniture moving and storage.
An exclusion is not a red flag by itself; contractors cannot price what nobody can see yet. The problem is a bid that silently excludes things another bid includes. New Jersey’s rules also make it an unlawful practice to fail to disclose that the price does not include permit fees or other charges the buyer will pay (N.J.A.C. 13:45A-16.2), so it is fair to ask for every excluded cost to be named.
Contingency and unforeseen conditions
Separate from the contractor’s price, keep your own contingency: commonly 10–15% of construction cost, and more in prewar NYC apartments and pre-1940 New Jersey houses, where walls hide more surprises. A good estimate also explains how unforeseen conditions will be priced: at a stated unit price (per sheet of subfloor, per linear foot of pipe), at time and materials with stated hourly rates, or by written change order before the work is done.
Change orders
A change order is a written amendment that changes scope, price or schedule. Both New Jersey and New York require changes to a home improvement contract to be in writing and signed. A useful change order states:
- what is being added, removed or substituted;
- the price change, including markup;
- the effect on the completion date;
- signatures and date, before the work is done.
Ask at the start how change orders are priced (fixed price, cost plus a stated percentage, or time and materials) and how quickly they will be turned around, so decisions do not hold up the crew.
Payment schedules
A fair schedule ties each payment to a stage of work you can see, not to dates on a calendar. A typical structure for a kitchen or bathroom:
| Milestone | Common share of contract |
|---|---|
| Deposit at signing (orders long-lead items: cabinets, custom glass, stone) | 10–30% |
| Demolition complete, rough plumbing and electrical inspected | 20–25% |
| Walls closed, waterproofing done, cabinets delivered | 20–25% |
| Tile, countertops and fixtures installed | 15–20% |
| Substantial completion and final inspections | 5–10% |
2026 planning pattern, not a legal standard. Custom cabinetry ordered at signing can justify a larger first payment.
What the law says:
- New Jersey. It is an unlawful practice for a contractor to ask you to sign a certificate of completion or make final payment before the work is completed under the contract (N.J.A.C. 13:45A-16.2). The contract must also include the contractor’s HIC registration number, and contracts with registered contractors must carry the cancellation notice required by the Contractors’ Registration Act, which gives you until midnight of the third business day after you receive a copy of the contract to cancel in writing.
- New York. According to the New York Attorney General, payments received before substantial completion must be deposited in a trust (escrow) account at a New York bank within five business days, or covered by a bond or contract of indemnity, and progress payments must bear a reasonable relationship to the work done or materials purchased. You also have three business days after signing to cancel in writing. In New York City, the contractor also needs a DCWP Home Improvement Contractor license.
Comparing two or three bids
- Put the bids side by side in a spreadsheet, trade by trade.
- Normalize allowances: replace each bid’s allowances with the same numbers based on your actual selections.
- Add back anything one bid excludes and another includes (permits, debris removal, painting, appliance installation).
- Compare schedules: a shorter duration with the same scope may mean a larger crew, or an optimistic plan.
- Ask each contractor what they think the others missed. You learn a lot from the answers.
Once normalized, bids from qualified contractors are often closer together than they first looked. For realistic totals, see our New Jersey kitchen cost guide, NYC kitchen cost guide and bathroom cost guide.
Red flags in an estimate
- Lump-sum pricing with no scope breakdown.
- No mention of permits on work that plainly needs them (moving plumbing, new circuits, removing walls).
- A large deposit with no long-lead materials to order.
- Payments tied to dates rather than completed work.
- Allowances far below what your selections cost.
- “Verbal” inclusions that are not written into the proposal.
At BDM we price kitchen and bathroom projects by trade, list allowances and exclusions explicitly, and tie payments to completed stages of work.
Frequently asked questions
What is an allowance in a renovation estimate?
A placeholder budget for an item you have not selected yet, such as tile, plumbing fixtures or lighting. If your final choice costs more than the allowance you pay the difference; if it costs less you should receive a credit. Low allowances are the most common reason a bid looks cheaper than it is.
Does a home improvement contract have to be in writing in New Jersey?
Yes for contracts over $500 under N.J.A.C. 13:45A-16.2, and all changes must be in writing and signed by all parties. The contract must describe the work and principal materials, the total price, and the start and completion dates.
How much deposit should I pay a contractor in NJ or NYC?
Commonly 10–30%, with larger first payments justified when custom cabinetry or other long-lead items are ordered at signing. In New York, payments received before substantial completion must be held in trust or bonded. Tie later payments to completed stages of work.
Can I cancel a home improvement contract after signing?
In both New Jersey and New York you generally have until midnight of the third business day to cancel, in writing. Check the cancellation notice in your contract for the exact procedure.
How much contingency should I add to a renovation estimate?
Commonly 10–15% of construction cost, and more in prewar NYC apartments and older New Jersey houses where hidden conditions are more likely.
