Local Intelligence
What The Colony Homeowners Need to Know Before Submitting
Size & Zoning Rules
Any new square footage added to your The Colony home counts against the same zoning envelope that governs ADU size, meaning large additions may affect your ability to add a future ADU. The Colony's current ADU size cap is 1,000 sq ft — within the typical range for most floor plan configurations.
The Colony does not impose an owner-occupancy requirement, so you can rent both the main home and any ADU or conversion as investment units.
If the addition creates a second unit or is later converted to a rental, The Colony's ADU market supports approximately $2,058/month for a 2-bedroom unit.
Permit Process & Fees
Building Inspections Department permit fees for this project type typically range from $1,000 to $2,500 depending on project valuation and scope.
Addition permit packages submitted to Building Inspections Department must include a site plan, floor plans, all four elevations, an electrical plan, and energy compliance documentation — plus stamped structural drawings are always required for any load-bearing elements, second-story work, or new foundation.
Visit Building Inspections Department ↗Construction Cost Context
The Colony's home addition construction costs run $280–$420 per square foot — a wide range driven by labor markets, local code complexity, and finish level. Our drawings are priced at a fraction of what a full-service architect would charge to produce the same permit set.
⚠ Common Pitfall in The Colony
Most lots in The Colony sit inside strict HOA-controlled subdivisions tied to the original master developer agreements, and several of these HOAs have architectural control committees that require separate approval before the city will even look at your permit — a step generic ADU guides never mention. Since STRs aren't allowed here, plan reviewers at the Building Inspections Department will also cross-check your application against the property's use type, so labeling the unit as a "guest suite" or "casita" rather than a rental unit on your plans can prevent a rejection loop. Denton County utility providers (often Coserv or Oncor depending on your section of the city) frequently require a separate service upgrade application for the ADU's electrical meter, which can add a few weeks if your existing panel is near capacity.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, when a permit timeline shows up blank and cost-per-square-foot is missing, it usually means the data you're looking at is a generic state-level placeholder rather than anything specific to The Colony — I'd call the Building Inspections Department directly before penciling in a schedule or budget. With HOA coverage at 56% here, don't underestimate that layer either; I've seen HOA architectural review add just as much delay as the city's own plan check."

Common Questions
The Colony Home Addition FAQs
Do I need a permit for a home addition in The Colony? +
Yes — any structural addition to your home in The Colony requires a building permit. This applies to room additions, second-story additions, sunrooms, and attached garages. You'll need permit-ready drawings before the building department will accept your application. Our packages are formatted specifically for The Colony's submittal requirements.

Second-story additions cost more than ground-floor extensions due to structural requirements. Contact us to discuss drawing package options for your project.
What drawings are required to permit a home addition in The Colony? +
The Colony's building department requires: a site plan showing the addition's footprint and setbacks, floor plans for all affected levels, all four exterior elevations, an electrical plan, and energy compliance (Title 24 in California). Structural plans stamped by a licensed engineer are required for any load-bearing elements — included in our Premium package.
How long does the permit process take for a home addition in The Colony? +
Plan check in The Colony typically takes 8 weeks for home additions. Additions with structural components may require additional review. Complete, code-compliant drawings significantly reduce correction cycles — each cycle adds 3–6 weeks. Our drawings are engineered to pass on the first submittal.
What setbacks apply to home additions in The Colony? +
The Colony enforces minimum setbacks from property lines for all additions: typically 4–5 ft side setbacks and 5 ft rear setbacks, though these vary by zoning district and lot size. Your addition must stay within the buildable envelope. Our site plan documents existing and proposed setbacks and flags any zoning variances required.
Do I need structural drawings for a home addition in The Colony? +
Yes, for most additions. Any load-bearing walls, new foundations, second-story construction, or roof structure changes require stamped structural drawings from a licensed engineer. California's CBC (California Building Code) and seismic requirements make structural plans mandatory for most addition types. Our Standard and Premium packages include stamped structural drawings.
How much do home addition drawings cost in The Colony? +
Our permit-ready home addition drawing packages for The Colony include everything your building department requires — floor plans, elevations, structural, and energy compliance. Every package is engineered for TX code compliance and formatted for The Colony's building department. 14-day money-back guarantee.
Will a home addition increase my home's value in The Colony? +
In The Colony, where median home values are approximately $400,000, a permitted home addition adds square footage that appraisers value as part of the home's gross living area. Return on investment varies by addition type — master suite additions, family room expansions, and additional bedrooms typically recoup 50–75% of project cost in appraised value in TX markets.
Can I add a second story to my home in The Colony? +
Second-story additions are permitted in most The Colony residential zones, subject to height limits and design review requirements. California generally requires ministerial permit approval, but some cities impose design compatibility or neighborhood compatibility review for second stories. Our drawings cover all levels including foundation upgrades, shear walls, and roof framing required for vertical additions.
