Del Mar Hills Water Damage Restorationfor condos, townhomes and shared walls

The communities known as Del Mar Hills are mostly attached housing: two- and three-story condo buildings, townhome rows and clusters of homes that share walls, roofs and grounds. They were built for people who want to be close to the coast without the upkeep of a detached house, and many are now several decades old, with original plumbing in the walls and under the floors.

In attached housing, water does not respect property lines. A failed toilet supply in an upstairs unit leaks into the kitchen ceiling below. A washing machine overflow seeps under a shared wall into the neighbor's hallway. A blocked shared drain backs up into the lowest unit on the stack. A roof leak over one unit soaks the attic insulation over two, and the stain shows up in a third.

Each of those situations involves at least two owners, and often the homeowners association too. Each may have its own insurer. Who pays for what depends on where the water started and on the association's governing documents, usually called the CC&Rs. Meanwhile, the water keeps spreading until someone dries it.

That is why the best response in Del Mar Hills combines fast mitigation with clear communication: stop the water, get every affected unit dried, and keep separate, careful records so the owners, the HOA and the insurers can sort out responsibility afterward.

Responsibility in a condo or townhome community is set by the CC&Rs and by California law. Most associations in the state are governed by the Davis-Stirling Common Interest Development Act, and their CC&Rs spell out which parts of the property the association maintains, usually the common areas, exterior, roof and shared systems, and which parts each owner maintains, usually the interior of the unit and fixtures that serve only that unit. ^[7]

In practice, the line can be blurry. A supply line that serves only one unit's toilet is usually that owner's. A shared riser inside a wall is usually the association's. A shower pan that leaks into the unit below might be the upstairs owner's responsibility, but the damage to the downstairs ceiling might be handled by the association's master policy, the downstairs owner's policy or the upstairs owner's liability coverage, depending on the documents.

You do not need to settle all of that before mitigation starts. Emergency drying protects everyone and is generally expected. Notify the HOA manager as soon as possible, tell your own insurer, and let the documentation do the work later. If you are unsure of your rights, the CC&Rs and your insurer are the places to start, and an attorney who handles community associations can help with disputes.

In a building with stacked kitchens and bathrooms, drain stacks carry waste from several units down to the sewer. When a stack blocks, the waste backs up into the lowest unit first, often through a shower, tub or toilet. The owner of that unit did nothing wrong, but their home now needs a sewage cleanup.

That cleanup follows the Category 3 process: containment, removal of soaked porous materials, cleaning, disinfection and drying. ^[1] The HOA usually arranges for a plumber to clear the stack, since it is a shared system. While the stack is blocked, residents above should avoid running water, which the HOA may need to communicate quickly.

If backups repeat, a camera inspection of the stack and the building's sewer lateral can show roots, cracks or buildup. That is an association repair in most communities.

Townhome rows behave differently from stacked condos. Each home typically runs from foundation to roof, but shares a wall with its neighbors on one or both sides. A leak on one side can wick through the bottom plate into the neighbor's wall. Attached garages on the ground floor often hold water heaters, and when a tank fails, water can run under the garage wall into the neighbor's garage or living space.

When you dry a townhome, ask the contractor to take readings on the neighbor's side of any shared wall that got wet. It takes little time to check and prevents a hidden problem from growing next door.

The Del Mar Hills communities sit above the beach, but the coastal marine layer still reaches them much of the year, and outdoor air is often damp in the mornings. Contractors usually dry with doors and windows closed and dehumidifiers controlling the air in each unit. In buildings with shared corridors or stairwells, containment keeps humid air in the drying zone.

Equipment runs around the clock and makes noise, which can affect neighbors through shared walls. Many contractors can position units to reduce noise, and the HOA can help by letting neighbors know what is happening and for how long.

After drying, repairs inside a unit, such as drywall, paint, flooring and cabinets, are usually arranged by the owner. Repairs to common elements, such as the roof, exterior walls, shared pipes and sometimes ceilings and floor structures between units, are usually arranged by the HOA. Many associations require approval for changes to flooring, especially hard floors in upper units, because of noise rules, so check before choosing new flooring.

Coordinate the schedule with the HOA and neighbors. If an association contractor is repairing a shared pipe in your wall, your own drywall repair waits until that is done.

Condo owners in California usually carry an HO-6 unit policy, which covers the interior of the unit, personal property and liability, while the HOA carries a master policy for the building and common areas. The master policy may have a large deductible, and the CC&Rs may say how that deductible is shared when a loss starts in a unit. Townhome owners may have different arrangements depending on whether the association insures the structures.

Notify your insurer promptly and give them the contractor's documentation for your unit. If another owner's leak damaged your home, your insurer may pursue their insurer after paying your claim. The California Department of Insurance offers consumer help if a claim stalls. ^[3]

Many units in hillside condo communities are rented out, and some owners live elsewhere. When a leak starts in a rented unit, the tenant may not know who to call, and the owner may be hours or states away. Tenants should know where the shut-off is and have both the owner's and the HOA's emergency contacts. Owners should make sure the management company can authorise emergency mitigation if they cannot be reached.

A tenant's belongings are usually covered by their own renters policy, not the owner's. Tenants should document their damaged contents separately and notify their insurer. The building and unit interior follow the owner's and the association's arrangements.

Most units in these communities have a balcony or patio with a sliding door. Balconies above other units rely on waterproofing and drains, just like decks on detached homes, and a failure leaks into the unit below. Patio sliders on ground-floor units can take water from runoff when landscaping or walkways drain toward the door.

Balcony waterproofing is often a common element maintained by the HOA, even though each owner uses their own balcony. If you see a stain on the ceiling below a balcony, report it to the HOA as well as your insurer. Sliding door tracks should be kept clear of dirt and leaves so their weep holes can drain.

Some condo buildings have parking garages or storage below the living units. Those spaces collect water from leaks above, from ramps during heavy rain and from failed sump pumps. Storage lockers and parked cars can be damaged, and electrical rooms and elevator pits are often located there. The HOA usually handles cleanup in common garages; owners handle their stored belongings. Report water in a garage immediately, because it can reach electrical equipment that serves the whole building.

Some communities in the hills date from the 1970s and 1980s. In units of that age, popcorn ceilings, drywall joint compound and some flooring may contain asbestos, and paint applied before 1978 may contain lead. ^[5] Because condo ceilings are often the first thing opened after a leak from above, ask the contractor to test before cutting. In a shared building, the HOA may also need to know, since dust can travel through common corridors and ventilation. Testing usually takes little time and keeps everyone in the building safer.
