Condo Remodel Cost

Updated September 2026 · Home Project Resources

Condo remodel cost sits meaningfully above the same scope in a single family house, and the gap is almost never the materials. It is access, protection of common areas, restricted work hours, board approval, higher insurance limits, and the plumbing you are not allowed to move. Two owners can buy identical cabinets and identical tile and still get very different bids, because one of them lives on the ninth floor of a building with a four hour work window.

That means the useful question is not what a condo remodel costs on average. It is which of the condo specific constraints apply to your building, because those are the items that separate your bid from a house bid.

A note on numbers. This page gives you the ownership split, the plumbing constraints, the approval package, the soft cost lines and the bid questions, not dollar figures. Labor is the majority of most condo work and it is priced locally, board fees are set building by building, and any printed range would be wrong for most readers. Take the scope below to three contractors who have worked in buildings like yours.

Condo remodel cost by scope

Read this as a scope ladder for a unit around 900 square feet with two bedrooms and two bathrooms, which is close to the national median. What separates the rows is how deep into the building you reach, and that is what the board and your bidders both care about.

Four factors move a condo project inside its band more than anything else: the building's age and what is inside the walls, how many floors up the unit sits, how strict the association's rules are, and whether the layout change touches plumbing.

Why condo work costs more than house work

The same kitchen costs more on the ninth floor. Here is where the premium actually goes:

• Material handling. Everything arrives through a single loading dock, a reserved elevator, and a hallway that has to be papered and protected. This is a real percentage of labor on its own.
• Debris removal. No dumpster in the driveway. Demolition debris goes down in bags or carts, often on a schedule, and disposal is more expensive per load.
• Restricted hours. Many buildings allow work only between mid morning and mid afternoon on weekdays. A crew losing two productive hours a day stretches a six week job to eight, and you pay for the weeks, not the hours.
• Protection of common areas. Masonite on corridor floors, corner guards in the elevator, and a full cleanup at the end of every day.
• Insurance requirements. Boards routinely require higher liability limits and the association named as additional insured, which narrows your contractor pool and pushes bids up.
• Permit plus board review. Two separate approval tracks, often sequential rather than parallel.

What you own and what the association owns

This single question decides who pays for what, and it is answered by your condominium declaration rather than by common sense. Read the declaration and the bylaws before you price anything.

The typical split in a US condominium:

The practical consequence: you can remodel everything inside the drywall and almost nothing behind it. A tub you want to move eight feet may be blocked because the drain has to reach a stack you are not allowed to touch, and no budget solves that.

The plumbing stack rule, in plain terms

Waste plumbing needs slope, usually 1/4 inch of fall per foot of horizontal run. In a house you get that slope in the joist bay under the floor. In a concrete slab condo there is no joist bay. The drain runs in a limited depth of floor buildup, or it does not run at all.

That is why relocating a toilet more than a few feet is often either impossible or expensive. The workarounds, from cheapest to most expensive:

• Stay put. Cheapest by a wide margin. Keep every drain within about 3 feet of its current location and the whole job stays simple.
• Raise the floor. Build a platform to gain slope. This is a substantial adder and it creates a step, a door height problem, and sometimes a headroom problem.
• Macerating or upflush toilet. Cheaper than raising the floor, allowed in some buildings and banned outright in others. Ask before you design around one.
• Core drill to the stack below. Requires structural engineering, board approval, and access to your downstairs neighbor's ceiling. The most expensive option and frequently denied.

Kitchens are usually more forgiving than baths, because a sink drain can run inside a base cabinet with less depth to find. Moving a kitchen sink six to ten feet along the same wall is often approvable. Moving it to the opposite side of the room usually is not.

The HOA and board approval process

Plan for this to add 4 to 12 weeks before demolition starts, and longer in older buildings with a volunteer board that meets monthly.

A typical approval package asks for:

1. A written scope of work, room by room.
2. Drawings, from a simple layout for cosmetic work up to stamped architectural plans for anything structural or plumbing related.
3. Your contractor's license and certificate of insurance, with the association named as additional insured.
4. A construction schedule that fits the building's work hour rules.
5. An alteration agreement that you sign, accepting responsibility for damage to other units.
6. A refundable damage deposit, which you must float for the duration of the job.
7. An application or review fee. Larger buildings sometimes charge an engineer review fee on top of it.

Budget the soft costs as their own line. Board fees, drawings, deposits and elevator reservations are real spending that never appears in a contractor's bid, and on a mid range unit they add up to a meaningful share of the project before a single tile is cut. High rise buildings in major cities run far higher, and some require you to hire the building's own engineer at their rate rather than one you choose.

Sound transmission is the rule people trip on

Most condominium documents set a minimum sound rating for hard flooring, typically an Impact Insulation Class of 50 to 60 with an approved underlayment, or they simply require a percentage of the floor to stay carpeted. Some ban hard surface flooring above the first floor entirely.

Compliant acoustic underlayment adds to the floor line and it is not optional. Installing hard flooring without it is the most common cause of a condo owner being ordered to tear out finished work at their own expense, which is by far the most expensive mistake available in this whole article.

Ask the property manager for the exact rating requirement in writing before you choose flooring. The material comparison is in cost to install flooring and laminate vs vinyl plank.

Room by room: condo constraints, not house constraints

Two of those lines deserve a warning. Electrical panel upgrades are often limited by the building's total service capacity, so the answer can be a flat no regardless of what you are willing to spend. Adding a washer and dryer where none existed triggers a leak risk review in most associations, and many now require a pan, a drain and an automatic shutoff valve as a condition of approval.

For the underlying room level scope these condo constraints wrap around, see kitchen remodel cost and bathroom remodel cost.

Building the budget: 900 sq ft two bedroom, mid range remodel

Scope: keep the layout, new kitchen, both bathrooms redone with fixtures staying put, new flooring throughout, full repaint, new interior doors and trim, updated lighting. Sixth floor, 1980s building, elevator access, weekday work hours only.

The hard cost lines that belong on the proposal, each priced separately so three bids are comparable:

• Demolition and protected debris removal
• Kitchen: cabinets, counters, sink, faucet, tile backsplash, install labor
• Appliance package
• Primary bathroom: tile shower, waterproofing, vanity, toilet, fixtures
• Second bathroom: tub surround, vanity, toilet, fixtures
• Flooring, with the rated acoustic underlayment named as its own line
• Interior paint, walls, ceilings and trim
• Interior doors, casing and baseboard, quantity stated
• Electrical: recessed lighting, added outlets, dimmers, permitted
• Plumbing rough and trim, with fixtures staying in place
• HVAC: replacing the in unit air handler, cleaning and rebalancing

The condo specific soft cost lines, which most homeowners forget entirely:

• Architectural drawings for the board submission
• Board application and engineer review fees
• Building permit and inspections
• The refundable damage deposit, which is returned but must be floated
• Elevator reservation and corridor protection
• The additional insured endorsement the contractor passes through

Hold contingency as its own line, at 15 percent on a building of this age. In condos the contingency reliably gets spent on three things: a plumbing riser condition nobody knew about, a floor slab that is out of level by more than an inch across the unit, and a board comment that arrives after approval and forces a change. An 1980s building also has a real chance of cast iron drains, aluminum branch wiring, or no insulation at the demising wall, and all three are found rather than planned.

The reason to lay the budget out as two lists rather than one total is that the soft costs are invisible in every contractor bid you will receive. If you only compare hard costs, you will be surprised by a number that was always going to be there.

Where a condo remodel returns money, and where it does not

Condo resale rewards a narrower set of upgrades than a house does, because buyers cannot change the layout, the views, or the monthly assessment.

Usually returns well

• Kitchen and bathroom updates that read as current and clean.
• Consistent hard flooring throughout, where the building allows it.
• Better lighting, which makes interior units feel larger for very little money.
• Closet and storage systems, since condos are chronically short on storage.

Usually returns poorly

• Luxury finishes above the building's price tier. A kitchen finished to a standard the rest of the building does not reach will not come back at sale.
• Removing a bedroom to make an open plan. Bedroom count drives condo pricing more than square footage does.
• Anything the next owner has to maintain and the association will not, such as a custom balcony surface.

The honest test is comparative: look at three recently sold units in your own building rather than at market averages. For how a condo project compares against the same work in a detached home, see home remodel cost and whole house remodel cost.

Permits still apply

A common and expensive misunderstanding: board approval is not a permit. They are separate tracks, and you generally need both.

Most US jurisdictions require a permit for plumbing changes, new or altered electrical circuits, HVAC replacement, and any change to walls. Paint, flooring, cabinets and fixture swaps in place usually do not, though some cities require an interior alteration permit for any work above a stated valuation threshold.

Licensed trade work is not optional. Electrical, plumbing and mechanical work in a multi family building is licensed and inspected in nearly every state, and the fire and life safety systems, meaning sprinklers, smoke detectors and fire rated assemblies between units, are inspected closely. Cutting a sprinkler line or breaching a fire rated demising wall is the kind of mistake that becomes a legal problem rather than just a repair.

Call the building department once before you finalize the scope. It is the cheapest hour of the entire project.

Questions to ask before you sign anything

• What are the building's permitted work hours, and how many working hours a day does that leave the crew?
• What Impact Insulation Class does the declaration require, and can I have that in writing?
• Is there a required elevator reservation process, and who pays for the time?
• What insurance limits does the association require, and can this contractor meet them?
• How far can a drain move in this unit given the slab depth, and has anyone in the building done it?
• Are upflush units permitted in this building?
• Is there spare electrical capacity in the riser for a panel upgrade?
• What did the last three alteration applications in this building get flagged for?
• What is specifically excluded from this proposal?

Frequently asked questions

What does it cost to remodel a 1,000 square foot condo?

It depends far more on the building than on the unit. Get answers to four questions first: how many hours a day a crew may work, whether the flooring rule forces a specific underlayment, whether the fixtures can stay where they are, and whether the board requires stamped drawings. Those four decide the schedule and the scope, and the schedule is where condo work gets expensive. Then take one written scope to three contractors who already work in buildings like yours.

Do I need HOA approval to remodel my condo?

Almost always, for anything beyond paint. Most declarations require written approval for flooring, plumbing, electrical work, wall changes and anything visible from a common area. Approval typically takes 4 to 12 weeks and asks for a scope of work, drawings, your contractor's insurance certificate naming the association, a schedule, and a signed alteration agreement with a damage deposit. Starting without it risks a stop work order and an order to restore the original condition at your expense.

Can I move plumbing in a condo?

Sometimes, and rarely far. In a concrete slab building, waste lines need about 1/4 inch of fall per foot and there is little floor depth to work with, so drains generally have to stay within a few feet of the existing stack. Main stacks and risers are association property and cannot be altered by an owner. The usual options are keeping fixtures near their current spots, raising the floor to gain slope, or installing an upflush unit where the building permits one.

Why is condo renovation more expensive than house renovation?

Most of the difference comes from access and rules rather than from finishes. Materials go up in a reserved elevator, debris comes down in carts, common areas need daily protection, work is often limited to a short weekday window, insurance limits are higher, and board review adds fees, drawings and weeks of schedule. None of that appears in a per square foot average built from single family data, which is why those averages mislead condo owners so consistently.

What flooring is allowed in a condo?

Check the declaration for a required Impact Insulation Class, commonly 50 to 60, and for any carpet coverage percentage. Luxury vinyl plank, engineered wood and tile are all typically allowed over an approved acoustic underlayment. Some older buildings ban hard surfaces above the ground floor outright. Get the requirement in writing from the property manager before you buy anything, because the tear out order comes after the floor is finished.

How long does a condo remodel take?

Board approval takes 4 to 12 weeks, permitting another 2 to 8 weeks, and construction runs 4 to 8 weeks for a cosmetic refresh, 8 to 14 weeks for a mid range remodel, and 14 to 24 weeks for a full gut. Restricted work hours stretch every construction estimate by 20 to 40 percent compared with the same scope in a house. Order long lead items such as cabinets and tile during the approval window rather than after it.

Does a condo remodel increase the value of the unit?

Kitchen and bathroom updates, consistent flooring and better lighting usually return a meaningful share when they bring the unit in line with the rest of the building. Finishes above the building's tier rarely return, and removing a bedroom often reduces value even when the space feels better to live in. The reliable check is three recent sales in your own building, since a condo's value is capped far more tightly by its address than a house's is.
