Va. Code § 15.2-2204
The local planning commission shall not recommend nor the governing body adopt any plan, ordinance or amendment thereof until notice of intention to do so has been published twice in some newspaper published or having general circulation in the locality, with the first notice appearing no more than 28 days before and the second notice appearing no less than seven days before the date of the meeting referenced in the notice; however, the notice for both the local planning commission and the governing body may be published concurrently. The notice shall specify the time and place of hearing at which persons affected may appear and present their views. The local planning commission and governing body may hold a joint public hearing after public notice as set forth in this subsection. If a joint hearing is held, then public notice as set forth in this subsection need be given only by the governing body. In any instance in which a locality has submitted a correct and timely notice request to such newspaper and the newspaper fails to publish the notice, or publishes the notice incorrectly, such locality shall be deemed to have met the notice requirements of this subsection so long as the notice was published in the next available edition of a newspaper having general circulation in the locality. After enactment of any plan, ordinance or amendment, further publication thereof shall not be required.
When a proposed amendment of the zoning ordinance involves a change in the zoning map classification of more than 25 parcels of land, or a change to the applicable zoning ordinance text regulations that decreases the allowed dwelling unit density of any parcel of land, then, in addition to the advertising as required by subsection A, the advertisement shall include the street address or tax map parcel number of the parcels as well as the approximate acreage subject to the action. For more than 100 parcels of land, the advertisement may instead include a description of the boundaries of the area subject to the changes and a link to a map of the subject area. Written notice shall be given by the local planning commission, or its representative, at least five days before the hearing to the owner, owners, or their agent of each parcel of land involved, provided, however, that written notice of such changes to zoning ordinance text regulations shall not have to be mailed to the owner, owners, or their agent of lots shown on a subdivision plat approved and recorded pursuant to the provisions of Article 6 (§ 15.2-2240 et seq.) where such lots are less than 11,500 square feet. One notice sent by first class mail to the last known address of such owner as shown on the current real estate tax assessment books or current real estate tax assessment records shall be deemed adequate compliance with this requirement, provided that a representative of the local commission shall make affidavit that such mailings have been made and file such affidavit with the papers in the case. Nothing in this subsection shall be construed as to invalidate any subsequently adopted amendment or ordinance because of the inadvertent failure by the representative of the local commission to give written notice to the owner, owners or their agent of any parcel involved.
The governing body may provide that, in the case of a condominium or a cooperative, the written notice may be mailed to the unit owners' association or proprietary lessees' association, respectively, in lieu of each individual unit owner.
Whenever the notices required hereby are sent by an agency, department or division of the local governing body, or their representative, such notices may be sent by first class mail; however, a representative of such agency, department or division shall make affidavit that such mailings have been made and file such affidavit with the papers in the case.
A party's actual notice of, or active participation in, the proceedings for which the written notice provided by this section is required shall waive the right of that party to challenge the validity of the proceeding due to failure of the party to receive the written notice required by this section.
This subsection shall not apply to inquiries from the governing body, planning commission, or employees of the locality made in the normal course of business.
