Building during the spring and summer months is generally more efficient for exterior work and foundation pouring. We plan projects to account for these seasonal shifts, aiming for a smoother build.

Permitting for accessory dwelling units in Missouri is handled at the local city level. Each municipality, including St. Louis and Independence, has its own unique zoning and building regulations. Understanding these specific requirements is crucial for a successful ADU project. We guide you through the process to ensure all local standards are met.
