FAQ: Getting Started: Location, Permits & Site Prep
What is the best location for a greenhouse?
For year-round success, install your greenhouse on a level, stable surface with access to at least 6 hours of direct winter sunlight. Choose a site with good drainage, proximity to water and electricity, and minimal shade from buildings or trees.
Do I need a building permit for a greenhouse?
Permit requirements vary by location. In many areas, structures under 120 sq. ft. that are not permanently fixed do not require a permit. If needed, we provide stamped engineering drawings to support your application. Check out our Help Center for more information.
What’s the best foundation for my greenhouse?
A level wood or concrete base is ideal:
Wood Foundation: Easy DIY, flexible for future relocation. Typically lasts around 15 years depending on climate. Larger greenhouses require larger timbers.
Concrete Base: Permanent, long-lasting, low maintenance.
Bricks and mason blocks are not recommended due to shifting and cracking.
All foundations must be level and square. We include a foundation sketch with exact dimensions. Read our Essential Guide to Greenhouse Foundations for information about site location, prep, best building materials and ballpark prices.
What flooring options are best inside a greenhouse?
Gravel + Pavers: Affordable, easy to clean, popular for DIYers.
Concrete Slab: Durable and easy to clean, ideal for decorative spaces and long lasting.
Bricks and Tiles: Good mid-range option using stamped sand as a base.
Not recommended: Bare Soil due to risk of disease and infestation.
