Ways to lower your Tampa price
- Use pre-approved ADU plans where your city offers them — saves months and design fees.
- Detach only if required; attached and conversion ADUs cost far less.
- Collect three written bids on an identical scope — spreads of 20–40% are normal.
- Book in the off-season and stay flexible on the start date to save 5–15%.
- Bundle nearby work into one mobilization so you only pay setup and travel once.
- Ask what the contractor would change to cut 10% without hurting durability.
