How Lafayette calculates your permit fee

The city charges a building permit fee using $3.50 per $1,000 of project value, with a $35.00 minimum. Plan review is a separate charge: a flat $50.00. Electrical, plumbing and mechanical work gets its own permits.

The fee table

Residential new, renovation, addition (and demolition)

$3.50 per $1,000 of project value, with a $35.00 minimum.

Commercial new, renovation, addition (and demolition)

$5.00 per $1,000 of project value, with a $100.00 minimum.

What counts as project value

Your contract or bid price. Building fees are charged 'per $1000 fair market value of improvement'. The schedule does not say how fair market value is determined (applicant estimate vs. a table).
