Summary
In West Palm Beach's historic residential districts, new houses and additions are capped by a sliding-scale floor area ratio and lot coverage table set by lot size, so bigger lots do not get proportionally bigger houses. The SF7-C4 district caps FAR at 0.45 on lots under 5,000 square feet, dropping to 0.35 on lots of 7,500 square feet and up.

Full Breakdown
Chapter 94, Article III applies scale limits in every historic residential district (Northwood Harbor, Northwood Hills, West Northwood, Vedado/Hillcrest, Flamingo Park, Old Northwood, El Cid, Belair, Grandview Heights, Prospect/Southland Park, Northwest, Central Park and Mango Promenade, per Sec. 94-78's Table III-2) to keep new construction from overwhelming the neighborhood scale. Sec. 35. Every other historic district (Sec. 94-81 through 94-84) carries the same sliding-scale structure with district-specific numbers, so the FAR percentage falls as the lot gets bigger rather than staying flat. Sec. 94-86 defines what counts toward that FAR: 100 percent of any roofed space enclosed on more than two sides, garages, mezzanines, stairways and utility rooms count in full, while roofed carports, porches and breezeways open on more than one side count at 50 percent, and unroofed terraces, balconies and eave overhangs up to three feet are excluded entirely.
Sec. 94-79 ties the numeric caps to a compatibility review, stating the standards work with the City of West Palm Beach Design Guidelines to evaluate whether a proposed structure is compatible with surrounding properties in terms of size, scale and massing. Limited relief exists only through Sec. 94-85 special exceptions reviewed by the historic preservation board or city staff, capped at specific percentage add-ons per lot-size tier and requiring design elements that reduce visual massing.
Violations & Fines
Building permit plans that exceed the district's lot coverage or FAR table are rejected at plan review by the city's building and planning divisions; construction proceeding without a compliant permit is subject to stop-work action and unsafe/unpermitted-structure enforcement under Chapter 18. Exceeding the base standard requires an approved special exception under Sec. 94-85 before a permit issues; building without one leaves the excess floor area in violation and subject to removal or reduction as a condition of any after-the-fact approval.
