You mist comply with the terms of your lease. If the tenants are on a month to month lease, you must give them proper notice. Otherwise, you need to wait until the end of the lease term. For best results, you should consult a a landlord's attorney in the area where the property is located. It may be too late to serve notice on 4/1 if more than 30 days is required by OR law.
Tenants who have lived in a rental residence for over a year are entitled to 60 days' notice prior to termination under Oregon law. If you're acting as a landlord, you need to consult with an attorney to ensure that you fully comply with notice requirements. Oregon rental laws are fairly tenant-friendly and landlords can be penalized for not complying properly.

Mr. Bodzin gives good advice here. The notice requirements in Oregon's Landlord-Tenant Act are very specific. In addition to you needing to give 60 (rather than 30) day's notice because the tenants have lived there more than one year, there are also requirements about how the notice is served, and what the notice must say. If you haven't served such a notice before, there are many potential mistakes you can make which might allow a tenant to contest a later eviction. This can cost landlords a lot of unnecessary time and money and sometimes a landlord is even ordered to pay a tenant's legal fees for an otherwise innocent mistake. It would be money well spent to consult with a landlord-tenant attorney in your area.
My responses to posts on AVVO are not legal advice, nor do they create an attorney-client relationship. In order to provide true (and reliable) legal advice, an attorney must be able to ask questions of the person seeking legal advice and to thus gather the appropriate information. In order for an attorney-client relationship to exist, you and I both have to agree the the terms of such an agreement.
