How long does it take to build a pool in Maryland?

The Short Answer: 8–14 Weeks From Permit Approval

From permit approval to final inspection, most custom in-ground pools in Anne Arundel County take 8–14 weeks of active construction. But permit approval itself takes 4–8 weeks after application submission — and that clock doesn’t start until the design is finalized and the application is filed. Total elapsed time from signing a contract to swimming is typically 16–26 weeks. The most common reason pools take longer than expected is starting the process too late in the season.

The Four Phases That Determine Your Timeline

• Phase 1 — Design and contract (1–3 weeks): After your free estimate, Wade prepares the design and contract documents. Simple projects on standard lots move faster; larger projects with outdoor kitchens, complex grading, or HOA submittals take longer. This phase is largely within your control — decisions made quickly move the project forward.
• Phase 2 — Permitting (4–10 weeks): Wade submits the complete permit application to Anne Arundel County (or your county). Standard residential pools typically take 4–8 weeks for permit approval. Critical Area properties add 2–4 weeks. Applications submitted in fall and winter move faster than spring submissions because building departments are less backlogged. This phase is largely outside your control once the application is submitted — which is why timing the contract matters so much.
• Phase 3 — Active construction (8–14 weeks): Once permit is in hand, construction begins. The sequence runs: layout and staking → excavation (1–3 days) → steel and plumbing rough-in (1–2 weeks) → gunite (1 day, then 28-day cure) → coping and tile (1–2 weeks) → decking (1–3 weeks) → interior finish (plaster or pebble, 1–2 days, then 1-week cure) → equipment installation and startup (1 week) → final inspection.
• Phase 4 — Landscape and cleanup (1–4 weeks, overlapping): If landscape planting and hardscape elements beyond the pool deck are included, these are sequenced after construction is complete to avoid equipment damage to new plantings. Site restoration and cleanup are included in Wade’s project scope.

Timeline by Scenario for Maryland Pools

• Contract signed in October–November: Permit submitted November. Approval December–January. Construction February–April. Swimming by May or June. This is the ideal scenario — the pool is ready for the full Maryland summer.
• Contract signed in January–February: Permit submitted February. Approval March–April. Construction April–June. Swimming by late June or July. Still a strong outcome with most of summer ahead.
• Contract signed in March–April: Permit submitted April (high-volume month). Approval May–June (longer wait due to spring backlog). Construction June–August. Swimming August–September. Possible late-summer completion but not guaranteed for June 1.
• Contract signed in May–June: Most realistic completion is late summer or fall of the same year, or the following spring if complications arise. Wade will tell you honestly at the estimate whether a specific date target is achievable.

What Can Extend a Maryland Pool Timeline

• Critical Area review: Properties within 1,000 ft of tidal water require additional county review that runs parallel to (but separate from) the standard building permit process. Adds 2–6 weeks.
• Variance applications: If setback waivers or impervious surface variances are required, variance hearings add 6–12 weeks to the permitting phase.
• Weather delays: Maryland winters can interrupt excavation and gunite work. Extended cold snaps (below 40°F) prevent gunite application. Wade factors seasonal risk into the construction schedule.
• Material lead times: Premium coping stone, specialty tile, and custom equipment packages have lead times that must be ordered during the permitting phase to arrive in time for construction. Wade manages procurement as part of the project schedule.
• Scope changes after contract: Adding features (spa, outdoor kitchen, expanded deck) after construction has begun extends the schedule and may require permit revisions. Wade recommends finalizing scope completely before submitting the permit application.
