There is no reliable universal price for renovating an apartment. The useful answer is the total of the approved scope, local labor and materials, permits, building fees, professional services, tax, and a contingency for discoveries behind walls or floors.
For a current number, get itemized quotes for the same written scope. Old national “cost per square foot” figures can be especially misleading for apartments because access rules, work hours, elevators, debris handling, and board approvals may add costs that a house estimate does not include.

Fix the scope before comparing prices, then keep allowances and optional upgrades visible instead of burying them in one total.
What Affects Apartment Renovation Costs?
- Scope: cosmetic refresh, fixture replacement, full room rebuild, or layout change.
- Existing conditions: damaged substrates, outdated services, moisture, or work concealed behind finishes.
- Specification: stock versus custom cabinets, standard versus premium finishes, and appliance requirements.
- Building constraints: approvals, deposits, insurance, elevator booking, work-hour limits, protection of common areas, and debris routes.
- Location: local labor, material delivery, permits, tax, and contractor demand.
If you rent, written owner approval should come before design fees or purchases. If you own in a condominium or co-op, obtain the alteration agreement and building rules before assuming the work is allowed.
Should You Use a Cost per Square Foot?
A per-square-foot allowance is useful only for comparing projects with similar scope, finish level, location, and building conditions. It is a poor shortcut when one plan moves plumbing and another only paints.
| Budget line | What belongs in it | How to verify |
|---|---|---|
| Construction | Labor, materials, demolition, protection, cleanup | Itemized contractor quote |
| Professional services | Design, engineering, surveys, inspections | Written proposals |
| Approvals | Permits, plan review, building deposits and fees | Local authority and management |
| Owner purchases | Appliances, fixtures, finishes, delivery and tax | Current supplier totals |
| Contingency | Unforeseen but in-scope conditions | Set after risk review; do not hide upgrades here |
| Temporary costs | Storage, moving, alternate accommodation | Project schedule and household plan |
How Much Does an Apartment Renovation Cost by Room?
Room names do not set the price; systems and scope do. Kitchens and bathrooms often involve more trades because cabinets, appliances, waterproofing, plumbing, electrical work, and ventilation must coordinate in a small area.
Bedroom and living-room renovations
Painting and floor refinishing can be relatively contained. The budget changes quickly if the plan adds built-ins, new lighting circuits, window work, acoustic treatment, or wall changes.
Kitchen renovations
Keeping plumbing and appliance locations can reduce coordination, but it does not automatically make the project cheap. Cabinet dimensions, electrical capacity, ventilation, countertop fabrication, and delivery access still matter.
Price the cabinets, counters, appliances, plumbing fixtures, lighting, flooring, backsplash, labor, and disposal separately so one attractive allowance does not conceal missing work.
Bathroom renovations
Ask whether the quote includes demolition, substrate repair, waterproofing, tile layout, plumbing, ventilation, fixtures, hardware, and final sealing. Do not cover suspected leaks or unsafe materials without proper assessment.
Multiple rooms and layout changes
Combining rooms can share mobilization and finishing work, but structural changes and relocated services create dependencies. Get the building’s approval route before paying for a plan that cannot be built.
How to Compare Renovation Bids
- Give every bidder the same drawings, finish schedule, and list of owner-supplied items.
- Ask for labor, materials, allowances, exclusions, tax, cleanup, and schedule to be shown clearly.
- Confirm who obtains permits and building approvals and who pays related fees.
- Investigate a large price gap rather than automatically choosing the lowest bid.
- Put agreed scope, dates, payment stages, change-order rules, and warranties in the contract.
The Federal Trade Commission’s contractor guidance recommends checking licensing and insurance where applicable, getting multiple written estimates, reading the contract, and avoiding full payment upfront.

Old and Historic Apartment Renovation Costs
Older apartments may need investigation before the final price is dependable. Wiring, plumbing, moisture, uneven substrates, previous alterations, and hard-to-match finishes can all change the sequence of work.
A historic designation or building rule may limit changes to windows, doors, trim, or exterior-facing elements. The National Park Service National Register program explains the federal register, but local preservation rules and the property’s actual status must be checked separately.
Do not disturb suspected lead paint, asbestos-containing materials, mold, or unsafe wiring without qualified advice. Requirements and competent professionals vary by location.
Build the Final Budget from Current Quotes
Add the accepted construction proposal, professional fees, approvals, owner purchases, tax, temporary living costs, and a project-specific contingency. Keep optional upgrades on a separate list.
That total is more useful than a broad online average because it reflects your apartment, your building, and the work you are actually allowed to do.
