What Can I Build on My Lot? Navigating Zoning, Setbacks & HOAs in Cary, Raleigh, and the Triangle
If you’ve ever wondered “Can I build a second story?” or “Could we add a garage or in-law suite?” — you’re not alone. For homeowners across Cary, Raleigh, and the surrounding Triangle area, zoning codes, setback rules, and HOA restrictions are often the biggest unknowns when thinking about remodeling or building.
At David Pollard Architect, one of the first things we do during our Feasibility Design process is dive deep into your property’s limitations — and possibilities. Here’s a quick overview of what you should know before sketching any dreams on a napkin.
What Are Zoning and Setbacks?
Zoning determines what you can build on your property — from the type of structure (single-family, duplex, ADU) to height, lot coverage, and use. Setbacks are the invisible lines on your lot where you can’t build — usually a certain number of feet from the front, sides, and rear property lines.
These rules vary by municipality and even by zoning district, meaning what’s allowed in one part of Cary or Raleigh may not be allowed in another.
Common Scenarios We See
Infill Lots in Cary: Often have stricter rear yard setbacks and stormwater overlays, limiting how far back you can build.
Older Homes in Raleigh: May be considered nonconforming — which can actually open up more options with the right approach.
Corner Lots: Frequently have two "front" yards, which can complicate additions and accessory dwellings.
Golf Course or HOA Lots: Often include additional easements or design restrictions beyond what the city or county requires.
Don’t Forget the HOA
If your neighborhood has a Homeowners Association, there’s a good chance your project will need to go through Architectural Review — even if the city says it’s allowed. HOAs can impose:
Height or style restrictions
Requirements for roof pitch, siding, or exterior materials
Limits on detached structures, fences, and pools
Additional setbacks or design covenants
We help clients prepare and submit HOA applications, including the necessary drawings, renderings, and explanation of materials, so your design has the best shot at getting approved the first time.
How We Help
During our Feasibility Design phase, we:
Pull the zoning data for your exact address
Study any overlays (historic districts, flood zones, etc.)
Research HOA covenants (if applicable)
Review permit history and property constraints
Create a zoning and buildable area diagram
And most importantly — test design ideas within those constraints
This step helps you make informed decisions before investing in detailed plans or contractor estimates.
Real Talk: Why It’s Worth Getting It Right
We’ve seen projects stalled or abandoned entirely because a homeowner made assumptions about what was allowed. A smart early study can save you months of frustration — and thousands in redesign costs. It’s the foundation (literally) of a smart design process.
