Ask a landlord-tenant lawyer and get answers ASAP
Thank you for your question. I look forward to working with you to provide you the information you are seeking for educational purposes only.
Since they are interfering with your peaceable use and enjoyment of the premises, which the lease guarantees you by law and also interfering with your warranty of habitability, since the conditions you describe can make your premises not habitable, you can seek to give your landlord/management company a written notice that the construction, power washing without notice, constant construction noise and parking lot issues are all things that were known in advance and were not disclosed to you 6 weeks ago when you agreed to the lease and as such they breach your warranty of habitability and interfere with your peaceable use and enjoyment of the premises and you need to inform them this is a breach of your lease.
If they refuse to at least put you up somewhere else until the construction is done, you have grounds to seek to terminate the lease for their breach and sue them for damages including your return of your security deposit and cost of moving.
