Quick Answers About Clermont, FL ADUs
Market Context
Clermont has a median home value of $400,000. Adding an ADU typically increases that by 25% — approximately $100,000 in added equity. A 1-bedroom ADU in Clermont rents for approximately $1,539/month in the Lake County rental market , yielding a 5.4% cap rate on the investment. Occupancy averages 88% in this market.
Top Clermont neighborhoods for ADU investment include Lost Lake, Legends, Postal Colony, Bella Terra, Greater Pines. Spacious elevated lots and upscale single-family homes near downtown Clermont and Orlando Health South Lake Hospital make detached ADUs highly suitable. Country-club style community with large-lot single-family homes and strong executive rental demand from Clermont's growing professional base.
Permit Process
Permit applications are reviewed by the Building Services . Permit fees in Clermont range from $2,625 to $4,225 depending on project scope. Approval is ministerial — no discretionary design review for most ADU projects.
Many Clermont neighborhoods, especially the newer developments off Hartwood Marsh Road and around Hunter's Trace, are governed by HOAs with their own architectural review boards that can take 30-45 days to approve an ADU design — and they can reject exterior finishes or roof pitch even after the city approves your permit. Since Clermont sits on a mix of septic and city sewer depending on the subdivision, older lake-area lots often need a septic capacity evaluation before Lake County will sign off, which can add real cost if the existing system wasn't sized for a second unit. Because the city just dropped ADU impact fees to 25% of standard rates under Ordinance 2026-001, double-check with Building Services directly on your parcel's fee tier, since older approved estimates floating around online still reflect the pre-2026 numbers.
"In my 11 years reviewing Clermont ADU projects, I can tell you both that permit timeline and the cost-per-square-foot figure here are essentially placeholders — they read like state-level averages, not numbers pulled from our local Building Services queue or actual contractor bids I've seen come through recently. With HOA coverage at 45% adding its own layer of review on top of county permitting, I'd strongly urge you to call Building Services directly and get two or three local contractor quotes before you anchor a budget or schedule to what's listed here."

Property Eligibility
Is My Clermont, FL Property Eligible for an ADU?
Clermont homeowners are governed by local zoning ordinances — Florida law (§163.31771) only encourages, but does not mandate, local ADU approval. Here's what applies to your property before you start designing.
Single-Family Home
Permitted on single-family lots in Clermont under local zoning ordinances — Florida law (§163.31771) only encourages, but does not mandate, local ADU approval. No owner-occupancy requirement in Clermont — you can rent both units as investment properties. Review process and timelines are set by local ordinance — confirm the current process with the Building Services before designing.
Multi-Family Property
Additional ADUs on multi-family and duplex lots may qualify under local zoning ordinances — Florida law (§163.31771) only encourages, but does not mandate, local ADU approval — the exact number and type allowed depends on Clermont's local rules. Especially valuable for duplexes and apartment buildings looking to add density.
HOA-Governed Properties
Approximately 45% of Clermont homes are in an HOA. Florida Statute §720.3035 limits HOA control over certain interior changes but does not preempt CC&Rs that ban ADUs outright — Florida HOAs generally retain the ability to restrict ADUs through their covenants. Our drawings include HOA submission formatting.
Always verify eligibility with Building Services before designing.

Projected Returns
* Estimates only. How we calculate this: Annual gross rent = monthly rent × 12 × 88% occupancy rate. Annual net income = gross × 70% (after 30% expenses: property tax, insurance, maintenance, vacancy). Value added = median home value × 25% uplift (regional ADU comparables). Total return = net income × years + value added. Break-even = total build cost ÷ annual net income. Consult a licensed financial advisor before investing.

Local Zoning Rules
2026 Clermont ADU Rules
Clermont's 2026 ADU ordinance caps new units at 1,200 sq ft and 35 ft of height — in the typical range most ADU floor plans are designed around. Setbacks run wide — 7 ft side / 25 ft rear — which pushes the buildable envelope toward the center of the lot. Because of FL's statewide wind-load provisions (Florida Building Code wind design / High-Velocity Hurricane Zone rules), structural drawings for a detached ADU here need a licensed engineer's stamp — architectural sheets for a code-compliant unit under the size cap generally don't.
Permit fees run $2,625–$4,225 — in line with what most homeowners budget for permitting through Building Services. Submit directly to the department online — link below.
