Summary
Santa Maria doesn't set one citywide lot-coverage percentage. Residential zones control building footprint through minimum lot size and setbacks instead, but two zones cap coverage outright: the Freeway Service (FS) district allows no more than 30% of the site to be covered, and the Public Facilities (PF) district allows up to 50%, exclusive of public streets.
No development shall cover in excess of 50% of the total area of the property (exclusive of public streets).
Full Breakdown

Santa Maria's core residential zones take a different approach and carry no percentage cap at all. 09) rather than by a coverage percentage. 08, parcels under an acre are limited to one unit per 3,000 square feet of net land, and every dwelling unit must have at least 300 square feet of landscaped open area apart from the required yards.
08 sets one unit per 2,000 square feet of net land under an acre and requires 250 square feet of landscaped open area per unit. A homeowner asking what percentage of a lot can be built on gets a direct percentage answer only in the FS and PF districts; everywhere else, minimum lot size, setbacks, density and required open space do that job instead.
Violations & Fines
Exceeding a district's applicable standard, whether the FS district's 30% cap, the PF district's 50% cap, or a residential zone's minimum lot size or setback requirement, is a Code violation under Section 1-6.01: an infraction starting at $100 for a first offense and rising to $500 for repeat offenses within a year, or a misdemeanor punishable by up to $1,000 and six months in jail. Each day the noncompliant structure stands is treated as a separate offense, and the Hearing Officer may add administrative penalties up to $2,500 per day under Section 1-8.09.
