The DC Department of Buildings says a
swimming pool permit is required for construction or modification of a swimming pool, and notes that separate permits may also be needed for water-system work. The DC Office of Planning's
historic district maps list Georgetown as one of the District's neighborhood historic districts, which is why Georgetown projects need a more preservation-aware exterior strategy than most DC pool jobs. That usually means the pool is planned together with masonry, fencing, terrace materials, and equipment screening from the start, especially on enclosed courtyard lots where every visible change matters. For budgeting, Georgetown custom pool or plunge-pool projects commonly begin in the
$125,000–$220,000+ range once historic review, premium masonry integration, and constrained access are accounted for. More focused renovation scopes often start in the
$15,000 – $80,000+ range depending on the existing site structure. See our
Pool Permits Guide,
