Yes — a residential building permit is required for new home construction throughout South Mississippi. Requirements vary by jurisdiction: properties within city limits fall under that municipality’s building department, while unincorporated county properties fall under county authority. For context, Lamar County’s residential permit fee for unincorporated areas is just $50 — one of the lowest in the state. Call our Hattiesburg office at 601-264-5028 and we can help you identify which jurisdiction applies to your specific property and what plan documentation your permit application will require.

Absolutely — and most of our customers do exactly that. Our modification service can adjust virtually any element of any plan in our catalog: flip the layout to face your street, change the foundation type for your specific soil conditions, add or enlarge a covered porch, move the garage, resize rooms, add a bonus room, or adjust the exterior style. Every modification quote is completely free with no obligation, and most modifications are completed within 2–3 weeks of approval.

Every plan purchase includes a complete set of construction documents: floor plans, exterior elevations, building cross-sections, foundation plan, roof plan, and general construction notes. Most plans also include electrical layout and detailed framing information. Plans are delivered as a PDF to your email address within minutes of purchase. We also offer CAD file packages for builders who need editable files. All of our plans are designed to meet standard residential construction requirements — your builder will have everything needed to pull a permit and break ground.

Yes — our plans work with any licensed Mississippi contractor and we never restrict you to specific builders. Many local builders throughout South Mississippi are already familiar with our plan documentation and know it’s complete and accurate. Having your plans in hand before approaching contractors puts you in a stronger negotiating position and helps builders submit more accurate bids. We recommend getting quotes from at least two licensed Mississippi contractors before committing to a build contract.

Stock house plans — like the 350+ designs in our catalog — are professionally designed floor plans available for immediate purchase, typically priced between $700 and $2,500. They’ve been built many times across the country, which means the construction details are proven and your contractor can bid them accurately. Custom architectural design starts from scratch based on your specific brief and typically costs $8,000–$30,000 with a 3–6 month design timeline before you can even approach a builder. For most South Mississippi families building on standard lots, a stock plan with targeted modifications produces a home that feels completely personalized — at a fraction of the custom design cost.

Standard plan purchases are delivered as a PDF to your email address within minutes of completing your order — 24 hours a day, 7 days a week. If you’ve ordered a modification, our team typically completes changes within 2–3 weeks depending on the scope of work. If you need to discuss your order or have questions about your plans, our Hattiesburg office is available Monday through Friday, 9am to 5pm CST at 601-264-5028 or sales@houseplangallery.com.
