Thinking about opening up that closed‑off kitchen or adding a true owner suite to your 1950s Green Hills ranch? You are not alone. These classic homes have charm and great lots, but they also come with low rooflines, small rooms, and aging systems that make planning tricky. In this guide, you will learn what works well on a mid‑century ranch in Green Hills, how to navigate Metro Nashville permitting, what timelines and budgets to expect, and when a teardown might make more sense. Let’s dive in.
Set your goals and scope
Start with how you want to live in the home, then match scope to that vision. Typical ranch updates in Green Hills include:
- Reconfiguring to an open plan by removing walls between the kitchen, dining, and living rooms.
- Single‑story additions to expand the kitchen/great room, add an owner suite, or create a mudroom.
- Converting an existing garage to living space and adding a new garage footprint.
- Adding a new primary suite wing or rear bump‑out that keeps the scale low from the street.
- Considering a second‑story addition, which is possible but usually the most expensive path.
- Upgrading systems: HVAC, electrical panel capacity, insulation, and windows to improve comfort and meet energy code when triggered.
Be realistic about structural limits. A low‑pitched roof and shallow crawlspace or slab foundation can raise costs for dormers, second stories, and major plumbing re‑routes. If you plan a large addition or structural change, involve a licensed structural engineer early.
Respect Green Hills context
Green Hills lots vary, and the neighborhood has a strong established character. Design additions that fit nearby homes in size and massing. This helps resale and reduces neighborhood friction.
Trees, drainage, and topography also affect where you can build and what it will cost. Mature tree preservation, retaining walls, and stormwater controls can add time and budget. Some blocks have active neighborhood groups with informal design norms. It is wise to ask about expectations so your project feels compatible.
Permits and codes in Davidson County
Metro Nashville and Davidson County’s Department of Codes and Building Safety handles permits, plan review, and inspections. Start on the Metro Nashville website to confirm your property’s zoning, setbacks, and any overlays that affect height, massing, and exterior materials. If you are in or near an overlay, plan on extra coordination during design.
Typical review steps
- Pre‑design consult: Meet with an architect or designer and, if needed, consult Metro planning/codes staff for complex sites or overlays.
- Permit submittal: Provide architectural and structural drawings, a site plan showing setbacks, and mechanical, electrical, and plumbing sheets as required.
- Plan review: Expect comments and possible revisions before approval.
- Inspections: Schedule inspections for foundation, framing, MEP rough‑ins, insulation/air barrier, and a final inspection. Some projects require a Certificate of Occupancy.
Code triggers you should know
- Energy code: When you add conditioned space or replace significant parts of the building envelope, Metro enforces energy standards based on the IECC with local amendments. Confirm the current edition with Metro at the start of design.
- Structure: Removing load‑bearing walls, changing roof spans, or adding a second story typically requires engineered plans and may require new footings or foundation reinforcement.
- Electrical and plumbing: Older wiring or small panels often must be replaced when exposed. Plumbing changes may reveal cast‑iron stacks or clay sewer laterals that need repair.
- Hazardous materials: Homes built before 1978 may contain lead paint. Asbestos can be present in duct wrap, floor tiles, or insulation. Follow the EPA’s RRP guidance for lead paint and review EPA asbestos renovation information before work begins.
Smart pre‑work inspections
- Structural assessment by a licensed engineer for additions or second stories.
- Targeted testing for lead paint and asbestos if you will disturb walls, ceilings, or floors.
- Sewer lateral video inspection before major floor work or landscaping.
- Termite, moisture, and foundation checks, especially with older slab or crawlspace homes.
Timeline and budget basics
Every project is different, but these ranges help you stage your planning and expectations:
- Pre‑design and programming: 2 to 8 weeks.
- Design and permit drawings: 4 to 12 weeks, depending on complexity.
- Permit review and approval: 2 to 8 or more weeks, especially with overlays or multiple review cycles.
- Construction: 6 to 12 weeks for small remodels; 3 to 6 months for moderate additions; 6 to 12 or more months for major additions or a second story. New builds can be similar or longer depending on site work.
Key cost drivers include scope, structural changes, systems upgrades, site work for trees and drainage, and finish level. Lead or asbestos abatement and termite or foundation repairs are common surprises in homes from the 1950s. Use industry benchmarks like the Cost vs. Value report to sanity‑check expectations, then get written local bids.
Build a contingency. Older homes hide unknowns, so plan a 10 to 20 percent contingency depending on scope and age. This protects your schedule and helps you absorb discoveries without stalling work.
Plan for hidden conditions
Mid‑century ranches often reveal issues once walls open. Expect and plan for:
- Lead paint and asbestos in finishes or duct wrap that require special handling.
- Old wiring, undersized electrical panels, or outdated plumbing that must be brought to current standards.
- Rot in subfloors, sill plates, or framing and occasional termite damage.
- Unpermitted past additions that force revisions or regularization during permitting.
A little upfront testing and allowance in the budget prevents sticker shock later.
Choose the right team and contract
Hiring well is the best risk management. Use a simple, disciplined process:
- Get at least three written bids with clear scope, inclusions, exclusions, schedule, and payment milestones.
- Verify insurance. Ask for general liability and worker’s comp coverage. Confirm limits and policy status.
- Check licensing and registration with Metro and state boards. Confirm experience with similar Green Hills projects.
- Call references and drive by recent local work if possible.
- Require a written change‑order process and collect lien waivers with major payments.
Your contract should define scope, materials or allowances, milestones, retainage, payment schedule tied to inspections, responsibilities for permits and inspections, warranty terms, and how unforeseen conditions will be priced and approved. Hold a final retainage until punch list completion, final inspection, and lien waivers.
Finance your remodel
Most owners mix cash with one of these options:
- Home equity line of credit for flexible draws.
- Renovation mortgages such as FHA 203k or Fannie Mae HomeStyle. Local lenders can advise which programs they offer.
- Construction loans for large additions or new builds.
Some energy‑efficiency improvements may qualify for tax benefits. Consult a tax professional about your specific situation.
Remodel or teardown in Green Hills?
There is a point where scope, code upgrades, and structural fixes push a remodel near a new‑build budget. Consider a teardown if you see:
- Cost parity between full remodel plus additions and a new build that meets your program.
- Layout limits from the existing footprint, slab condition, or low ceiling heights that block your goals.
- Lot value and zoning support for a larger home that still fits neighborhood scale and context.
- A timeline advantage from new construction if your remodel would require extensive remediation.
Do a quick feasibility study before you commit. Ask your architect or design‑build team for:
- A comparative cost estimate: remodel vs. new build for your wish list.
- A zoning envelope check for setbacks, height, and lot coverage.
- A preliminary site plan that shows access, tree impacts, and stormwater management.
- A market analysis of resale outcomes for each option. Buyer preferences in our market often favor open kitchens, an owner suite with a walk‑in closet and en‑suite bath, garage parking, and outdoor living, which aligns with guidance from the National Association of Realtors.
Resale and neighborhood fit
Align your finished size and finish level with comparable homes in Green Hills. Overbuilding can reduce your return on investment in established neighborhoods. Target improvements that buyers value, such as an open kitchen and great room, an added bedroom and bath, a true owner suite, and functional parking.
Energy and mechanical upgrades can improve comfort and marketability. They also help meet energy code when triggered by your scope.
Step‑by‑step homeowner checklist
Use this quick plan to keep your remodel on track:
- Gather documents: plat, deed, prior permits, and any survey.
- Confirm zoning, setbacks, and overlays with Metro Nashville. Use property pages to look up parcel details.
- Hire a designer or architect for concept sketches and a permit feasibility check.
- Order inspections: structural/roof, termite, sewer lateral video, and targeted testing for lead/asbestos if you will disturb finishes.
- Get at least three contractor bids. Compare line‑by‑line scope, schedule, and exclusions.
- Build contingencies and schedule buffers. Plan for temporary housing if systems will be offline.
- Plan tree protection and erosion control if you will disturb the site.
- Track inspections, permits, and reports in a shared binder or digital folder.
- Use staged payments tied to inspections and collect lien waivers.
- Document all change orders and communicate weekly with your contractor.
