As President of my condo (highrise) that has guided my community through a few disasters (and we just had a major fire yesterday) - let me chime in here. But note that condos operate differently - you need to check your rules.
1) Does your community have a property management firm that carries out day to day duties?
a) If they do, go to them. The Board is not that involved in the process. Ask what the time line is. Ask what the anticipated date of removal is. Put your concerns in writing. So often people that complain only do so verbally and that does not help. Written complaints are forwarded on to the Board. And the Board oversees the actions of the management office.
b) If you do not have a community property office (management office), Again - put your concern in writing before the Board meeting. If you just show up, the Board has had no opportunity to discuss and plan a course of action.
2) Ask questions about insurance. Look to your community By-laws and House/Community Rules. If this fire happened in a community property area your community insurance may have kicked in. However, if there is a way to prove a resident "did it", you can be in for an insurance battle. Most often, as a member of a condo, your association fees pay into the community insurance that covers grounds and buildings, individual owners are responsible for their contents and interiors (upgrades and extras). When an owner is at fault for damage that leaks to community areas, often times the community insurance and the individual insurance battle... and often the individual insurance covers the build's deductible. This takes time. For example, the last major event we had, involving 8 floors in flooding, took over a year to resolve completely
3) That said, the condo can and should take actions needed in the best interest of the community. Obviously if there is a police or fire investigation, their hands are tied. But, if that is completed and there is an OK by insurance, your Management Office and/or Board should be moving on basic clean-up at least in publicly visible spaces. If they can and they have not, you might be able to cite rules on safety, security, rules on how property must look or be maintained. You could also call upon the Board's duty to act in the best interests of the community - property values fall into that category. Stress that you are concerned for the community and not for yourself and your resale ability. Board duty is not to a single person but to the community at large.
4) Beware of actions that cause a special assessment. Not only does that hurt your community image, that affects your end of year audit rating (which in turn impacts your resale attractiveness)... if the community is waiting on insurance or on an investigation, you might be stuck.
