Remodeling Inside a Claremont Condo: Approvals and Plumbing Walls

Remodel a house and the constraints are budget, code and permit. Remodel a unit in an attached community and there is a third constraint sitting between the other two: the building is not entirely yours, and some of what you want to change is not either.

This is not a reason to avoid remodelling attached homes. Plenty of excellent work happens in them. It is a reason to sequence the project differently - approvals first, demolition much later. This article covers what is typically movable, what is typically not, and how to run the process. It deepens the condo and townhome guide.

Start with the boundary, not the plan

Before drawing anything, establish where your separate interest ends. In many condominium plans it is defined at the unfinished surfaces - the inside face of the studs, the underside of the subfloor above, the top of the slab or subfloor below. Everything beyond that plane is common area, even though it is inside your walls.

That single fact explains most surprises. The stud cavity may not be yours. The pipe in it may not be yours. The concrete under your floor is almost certainly not yours. So a project that reads as interior on a floor plan may be touching association property at three points.

Find your unit on the recorded plan, read the boundary definition, and read the maintenance matrix. The tiers are explained in the common areas guide. Doing this first tells you which parts of your wish list are a design question and which are an approval question.

What is usually straightforward

The reassuring part. Most cosmetic and fixture-level work inside the unit is genuinely yours.

Paint and wall finishes. Cabinetry. Countertops. Plumbing FIXTURES replaced in place - a sink, a faucet, a toilet, a tub or shower fitted where the existing one sits. Light fixtures on existing circuits. Interior doors and hardware. Built-in storage. Appliances that fit existing utility connections.

Even here, two caveats. Communities frequently require notice for work involving contractors on site, contractor insurance certificates, and adherence to work hours. And any change that alters a fire-rated assembly or requires a permit is a code matter regardless of what the association says - the association's approval is never a substitute for a building permit, and a permit is never a substitute for the association's approval. You need both where both apply.

What runs into the association

Five categories reliably require approval, and often more than approval.

WALLS THAT MIGHT BE STRUCTURAL OR SHARED. Removing an interior wall in a multi-storey building is a structural question and frequently a common-area question. Never assume a wall is non-bearing because it looks like a partition. Engineering, permits and association approval all attach.

PLUMBING RELOCATION. Moving a kitchen or a bathroom means moving drain lines, which means opening floors or walls that are usually common area, and tying into stacks that serve other units. This is the single most restricted category in attached housing, and in many communities it is simply not permitted. Design around the existing plumbing walls and your project gets far easier.

ELECTRICAL SERVICE CHANGES. New circuits within your panel are usually fine. Increasing service, running new feeds, or touching a panel located in common area is not.

HEATING, COOLING AND VENTILATION. Equipment locations, condenser pads, roof-mounted units, duct runs and exhaust penetrations through exterior walls all touch common property. A range hood venting outside is a penetration, not a cosmetic upgrade.

FLOORING. This is the one that surprises the most owners. Replacing carpet with hard surface changes impact-noise transmission to the unit below, and many communities regulate it - requiring specified underlayment, a minimum acoustic rating, limits on which floors may have hard surface, or approval of the assembly. Check before you buy material. The reasons behind these rules are covered in the shared walls guide.

Two statutory areas to verify, not assume

California has legislated in areas where associations historically said no by default. Requests for reasonable modifications to accommodate a disability, and requests to install electric-vehicle charging equipment in a space the owner controls, are both governed by statutory frameworks that constrain what an association may require and refuse.

Both frameworks have been amended over time and the details matter. Treat them as concept-level here: know that a flat refusal may not be the final answer, and verify the current statute and the association's current policy before planning around either.

How to run the approval process

SUBMIT BEFORE YOU BUY MATERIALS. Approval processes take time, boards meet on a schedule, and requests routinely come back with conditions. Ordering cabinets against an unapproved layout is how projects stall.

SUBMIT MORE DETAIL THAN FEELS NECESSARY. Drawings, product specifications, the contractor's licence and insurance, the intended schedule. Applications get delayed far more often for incompleteness than for substance.

GET IT IN WRITING, AND KEEP IT FOREVER. Verbal approval from anyone - a manager, a board member, a neighbour who is on the board - is worth nothing at resale. The written approval is a document you will hand to a buyer years from now.

EXPECT CONDITIONS. Work hours, elevator or stairwell protection, debris handling, parking for trades, deposits against damage to common area, and a completion deadline are all normal.

UNDERSTAND WHO CARRIES THE RISK. Approved alterations frequently come with an agreement making the owner responsible for the alteration and any consequences of it, permanently and for future owners. Read that document properly; it survives your ownership.

Unpermitted and unapproved work already there

You will encounter units with work that has neither a permit nor an approval. That is a diligence question and a disclosure question rather than an automatic problem.

Ask what was done, when, by whom, and whether documentation exists. Understand that responsibility for unapproved alterations often follows the unit rather than the person who made them, and that an association can require removal or restoration. And treat undocumented plumbing or structural changes with particular seriousness, because those are the categories with real consequences behind them.

If you are the seller, assemble your approvals and permits before listing. It converts a buyer's open question into a closed one.

The workable approach

Design within the plumbing walls, upgrade everything cosmetic freely, treat anything that penetrates, spans or transmits as an approval item, and start the paperwork before the design is final. Attached homes reward that sequence and punish the reverse.
