Utah HB 82 (2023) requires most municipalities to allow ADUs on single-family lots, but implementation varies significantly by jurisdiction — owner-occupancy requirements, size limits, detached vs. attached restrictions. RainFire Builders tracks current ADU regulations for every municipality we serve and advises clients on what is permitted at their specific address before any design work begins. We also handle: short-term rental zoning compliance (which varies by municipality and changes frequently); variance applications; CUP applications; FAR and setback analysis; and HOA design review. Zoning regulations in Utah are actively evolving — what was accurate 12 months ago may not apply today.
