When it comes to residential development, especially for single-family homes and small communities, most of the success happens before the first shovel ever hits the ground. From navigating zoning to selecting the right house plans, the pre-construction phase sets the tone for everything that follows. At W.L. Martin Home Designs, we’ve worked with hundreds of developers across North America, and we’ve learned that having a solid pre-construction design checklist isn’t just helpful, it’s essential.
Whether you’re planning a handful of infill homes or a larger neighborhood project, the steps you take in the early stages can make or break your timeline and budget. This guide walks through the critical pieces to consider, with practical insights you can apply on your next build.
1. Analyze Your Lots and Local Zoning First
Before you even start browsing floor plans, you need to understand what’s allowed. Each lot will have its own unique constraints based on zoning, setbacks, height limits, and allowable square footage. Some municipalities have design guidelines or architectural controls that dictate roof pitch, exterior materials, or garage orientation.
According to the National Association of Home Builders (NAHB), roughly 25% of a home’s final price is driven by regulatory costs before and during construction. Understanding your local rules helps you avoid plan revisions down the line, which can be expensive and time-consuming.
2. Select Plans That Fit Lot Sizes and Buyer Expectations
Once you know what your site allows, you can start matching plans to your project goals. For example, a narrow infill lot may call for a 24-foot wide plan with a front-load garage, while a suburban lot might offer more flexibility. Square footage is important, but so is layout. Today’s buyers expect open concept living, large kitchen islands, and energy-efficient features — even in smaller homes.
Many developers find success offering a mix of 3-bedroom and 2-bedroom layouts ranging from 1,200 to 2,000 square feet. It allows them to serve first-time buyers, downsizers, and growing families within the same development. At W.L. Martin, we offer dozens of these types of plans that balance affordability with visual appeal.
3. Coordinate Early with Engineers and Consultants
Once you have a shortlist of plans, it’s a good idea to bring in your structural engineer or other consultants to flag any red flags early. Slab-on-grade foundation? They’ll need to check soil suitability. Plans with bonus rooms over garages? You’ll want to review any potential HVAC routing or beam requirements. Catching issues now can save you thousands later.
If your jurisdiction requires energy modeling, site drainage plans, or landscape design approval, now is also the time to pull those professionals into the conversation. Even if you’re working from stock plans, your local team may need to adapt details for compliance.
4. Don’t Skip the Plan Review for Code and Permitting
Even if your selected plan has been used before, that doesn’t guarantee it meets your specific state, county, or municipal building codes. Requirements around insulation, stair geometry, framing spans, and even egress windows can vary widely.
The International Residential Code (IRC) is updated every three years, and not every location adopts the same version at the same time. For instance, some U.S. regions are still using IRC 2018, while others have moved on to 2021 or newer. It’s crucial to ensure your house plans are up to date and adjusted to local amendments before submitting for permit.
5. Plan for Customization Requests and Revisions
Many developers prefer to standardize a few floor plans across multiple lots for efficiency, but you’ll often need to tweak details. Whether it’s flipping the layout for a left-hand garage, adjusting windows for privacy, or upgrading finishes, expect a few changes to meet market expectations or client requests.
At W.L. Martin, we specialize in plan modifications and can turn around changes quickly for developers who are trying to stay on a tight schedule. Having a go-to process for customizations can save days or even weeks during your pre-construction timeline.
6. Finalize Your Pre-Construction Package for Permits
Once you’ve verified your plans, coordinated with your team, and completed any revisions, you’re ready to submit for permits. Make sure your submittal package includes everything your city or county requires. This typically includes:
- Full construction drawings (site-specific if needed)
- Truss or structural framing details
- Energy compliance documentation
- Site plan with setbacks and easements
- Engineer stamps, if applicable
Submitting a complete and compliant package reduces the chances of delays or resubmittals, which can hold up your build schedule.
7. Have a Material and Spec Plan Ready for Bidding
Before breaking ground, create a specification sheet or schedule outlining key materials, finishes, and systems. This includes siding types, roofing materials, HVAC systems, windows, and insulation levels. Clear specifications allow subcontractors to provide accurate bids and ensure you don’t end up over budget due to vague expectations.
A well-prepared plan package also helps your superintendent and trades during the construction phase. Less guessing means fewer mistakes, fewer change orders, and smoother site coordination.
Conclusion
Pre-construction planning is where your project’s profit margins are protected. The more thorough and organized you are before construction starts, the fewer surprises you’ll face along the way. At W.L. Martin Home Designs, we work closely with developers to deliver house plans that are not only attractive and buildable but also easy to customize and permit.
