Upcoming Training
Building Codes Webinar
The National Park Service will host a training webinar on building codes and historic buildings for property owners, architects, developers, consultants, local landmark commissions, and the general public on May 2 and May 21 at 2 pm ET.
The training will focus on Preservation Brief 51: Building Codes for Historic and Existing Buildings: Planning and Maximizing their Application, issued in June 2024, and will, among other things, highlight alternative compliance methods available under model building codes for historic and existing buildings that can provide more flexible and less costly alternatives to meet state and local code requirements.
Preservation Brief 51 discusses how to meet the goals of building codes while preserving or minimizing alterations to the character-defining features, spaces, materials, and finishes of historic buildings. It also provides guidance for selecting the optimal code compliance method and suggests best practices for achieving code-compliant solutions that also allow for the preservation of a building’s historic character.
Marilyn E. Kaplan, Architect, FAPT, author of the Brief, and Antonio Aguilar, Technical Preservation Services, will present the webinar.
The NPS is offering the same webinar on two different dates for increased attendance opportunity. Registration is free and open to the public – please select one of the dates and use the registration links below. The webinar will be recorded and made available online in the future.

Frequent Program-Users Training on the Secretary's Standards for Rehabilitation
The National Park Service will hold a 1-1/2-day in-person advanced training on the Secretary of the Interior's Standards for Rehabilitation on June 10-11, 2025, in downtown Washington, DC.
This training is primarily intended for property owners, developers, architects, consultants, and other frequent users of the Federal Historic Preservation Tax Incentives Program already knowledgeable about the program requirements and the Standards for Rehabilitation. The training will be repeated virtually and later made available in an on-demand, recorded version for those unable to attend and so that it may be accessible to a broader audience.
The training will emphasize the inherent flexibility within the Standards by taking into account such issues in their interpretation and application as reasonableness, economic and technical feasibility, cumulative effect, and code and programmatic requirements. The training will also focus on applying the Standards to common property types and historic rehabilitation projects.
This training complements the frequent program-users training held in September 2023 focusing on the Historic Preservation Certification Applications intended to help streamline the review process and avoid incomplete submissions, delays in review, and their associated costs. That training was repeated virtually last year and will be available in an on-demand, recorded version in the coming weeks.
Prior registration is required to attend. Attendees are responsible for making their own hotel reservation arrangements.
Registrations will be accepted in the order received. To register, email Technical Preservation Services at NPS_TPS@nps.gov by Thursday, May 22, 2025, with your contact information (name, company, address, email address, and phone number) and whether you require any special accommodations. Questions may be directed to the same email address.
Please note that if for some reason the event is not able to go forward as planned, we recommend that your travel arrangements be made cancellable.
