What Happens When Common Area Damage Affects Private Units?
Last updated October 26, 2026
The short answer
Know What to Expect from Repairs
Repair work can involve drying, removing damaged materials, and rebuilding affected areas. The pros typically start by assessing the moisture levels and the extent of the damage, then plan the cleanup and any structural repairs. You might need to stay out of your unit for a while, depending on how severe the damage is.
The cost of repairs often depends on the size of the affected area, the type of materials involved, and how quickly the work starts. Policies vary, and your insurer decides what is covered. Check your policy and ask your insurance company about your coverage and any deductibles. If you live in Oakland, keep your insurance documents handy.
Document the Damage Early
Take photos and videos of every wet area, including the common space and your unit. Write down the date and time you noticed the damage, and keep notes on anything you move or discard. Good documentation helps you and your insurance company understand what happened and what needs repair.
If you have receipts for damaged belongings, keep them together. You may also want to note any temporary living costs, like hotel stays or meals, if you cannot use your kitchen. That information can be useful when you review your coverage. Policies vary, and your insurer decides what is covered.
Do not throw away damaged items until you have recorded them. Even a soaked carpet or a warped cabinet can show the extent of the problem. The pros can also document the moisture levels in their inspection, which adds another layer of detail to your records.
Coordinate with Building Management
Common area damage often involves shared responsibility between unit owners and the building's management. Find out who handles the repair work and who pays for what. Your lease or condo rules may explain the split, but if you are unsure, ask the property manager or your landlord.
You still need to protect your own belongings and unit. Move furniture away from wet walls, and use towels or buckets to catch drips if you can do so safely. Do not enter rooms with standing water or sagging ceilings, as those can be dangerous. See a doctor if you feel unwell from any exposure.
Keep communication open with the people managing the building. They may have a preferred process for repairs, and they might need access to your unit to check for shared walls or pipes. You can also ask them for a timeline, though exact schedules can change as the work progresses.
Protect Your Belongings and Health
Water damage can ruin furniture, electronics, clothing, and keepsakes quickly. Move items to a dry area if you can, and open windows for ventilation when the weather allows. Do not use electrical appliances near wet areas, and avoid touching standing water if there is any chance of contamination.
Mold can start growing within a day or two in damp conditions. If you see mold or smell a musty odor, mention it to the pros during the inspection. They can help identify the extent and recommend the right kind of qualified professional, like a mold professional, for any cleanup.
Plan for Structural Repairs
Once the drying is done, the next phase is repairing the structure. That can include replacing drywall, fixing floor joists, or repainting walls. The pros usually handle the cleanup and drying first, then a separate trade might do the rebuilding, such as a carpenter or a drywall professional.
You may need to schedule the repair work around your daily life. Ask the person in charge about access needs and how long each step might take. Some repairs require multiple visits, especially if the damage is extensive or if new issues are found during the work.
Keep an eye on the repaired areas after the work is finished. Look for new stains, warping, or unusual smells. If something seems off, contact the pros or the building manager to have it checked. Catching a problem early can prevent a second round of damage and extra hassle.

Payment depends on your building's rules and your insurance policy. Your insurer decides what is covered, and the building's policy may cover common areas. Ask your property manager for the details, and check your own policy to see what it includes.
Can I stay in my unit during the repair work?
Sometimes you can stay, but it depends on the extent of the damage and the type of work. If the pros need to cut into walls or dry large areas, the noise and dust may make it uncomfortable. Ask for a timeline and plan accordingly.
