A home renovation runs more smoothly when decisions happen in the right order. Define the work first, document existing conditions, confirm permit requirements, prepare drawings, build the budget, hire contractors, and plan inspections before construction begins.
At Get a Site Plan, we prepare non-certified site plans, floor plans, and elevation drawings online for homeowners and contractors. Our drawings can support permit and HOA submissions when the local authority accepts non-certified plans.
We do not issue permits, and our work does not replace a licensed surveyor, architect, or engineer when one is required.
Before you start: Your local authority having jurisdiction (AHJ) decides which permits, drawings, inspections, and licensed professionals are required for your renovation.
Think of the project as five phases rather than one long construction job.
| Phase | Main Decision | What You Need Before Moving On |
| Planning | What exactly are you changing? | Written scope and existing-condition records |
| Approvals | What does the AHJ require? | Permit requirements and required drawings |
| Pre-construction | Who will do the work and for how much? | Budget, contract, materials, and schedule |
| Construction | Is work happening in the correct sequence? | Completed structural work, rough-ins, and inspections |
| Closeout | Is everything finished and documented? | Punch list, final approvals, warranties, and records |
A clear scope gives you a reliable basis for drawings, contractor estimates, and later decisions.
“Renovate the kitchen” leaves too much open to interpretation. Write down every planned change: remove cabinets, move the sink, relocate an appliance, replace flooring, open a wall, add lighting, install larger windows, or extend the room.
Separate the list into three groups:
A detailed scope makes contractor estimates easier to compare and limits confusion after construction starts.
Measure rooms and openings. Photograph walls, ceilings, floors, utility equipment, plumbing fixtures, electrical panels, exterior walls, and areas where new construction may connect to the existing building.
Old drawings should be checked against current conditions. Houses change over time, and previous renovations may never have been added to the plans you received when buying the property.
For interior projects, a scaled plan gives the contractor and permit reviewer a common reference. We can prepare a digital floor plan from measurements, sketches, and other information you provide.
Confirm local requirements before construction so the project is designed around the approvals it actually needs.
Permit requirements depend on location and project scope. Cosmetic work may require little or no permitting. Structural alterations, additions, major plumbing changes, electrical work, mechanical work, demolition, and changes to a building footprint can require permits and inspections.
The 2024 International Residential Code provides a model framework covering permits for construction, enlargement, alteration, repair, demolition, and regulated building systems. Cities, counties, and states can adopt different editions and modify their requirements.
Ask the building department four questions:
Also check zoning rules, historic-district requirements, floodplain regulations, and HOA rules where applicable. A project that is exempt from one building permit requirement can still be subject to another local rule.
Small interior renovations may need a basic existing and proposed floor plan. Larger projects can require demolition plans, proposed floor plans, structural information, site plans, exterior elevations, electrical layouts, or other details.
The IRC states that permit documents may need a site plan showing new and existing structures and their distances from lot lines. Building officials can modify or waive that requirement for certain alteration or repair projects.
If you are adding a room, porch, deck, garage, ADU, or another structure that changes the property layout, a construction permit site plan can show the proposed improvement in relation to the house, property lines, setbacks, easements, and other relevant site features.
When a non-certified plan is enough: We can prepare drawings remotely using available GIS information, satellite imagery, property data, and details supplied by the owner. If the AHJ requests a boundary survey, certified measurements, engineering calculations, or stamped architectural documents, the appropriate licensed professional must provide them.
Once the scope is clear, turn it into a realistic budget, contractor plan, and construction timeline.
A useful renovation budget includes every project cost you can identify before work begins.
Renovations expose parts of a building that could not be inspected beforehand. Water damage, deteriorated framing, old wiring, corroded pipes, and previous construction defects can add work after demolition.
Keep the contingency available until walls are open and the major unknowns have been resolved. Optional finishes are easier to upgrade later than structural repairs are to ignore.
Give each bidder the same scope and drawings. A low bid based on fewer included tasks is not directly comparable with a higher quote covering the entire job.
The Federal Trade Commission recommends checking applicable licensing and insurance, collecting multiple written estimates, and using a written contract. Its contractor hiring guidance also warns against paying the full project amount upfront.
Before signing, confirm that the contract addresses:
Cabinets, custom windows, doors, specialty tile, appliances, plumbing fixtures, and engineered components can affect the schedule. Order long-lead items early enough to prevent an empty jobsite halfway through construction.
Dimensions matter as much as delivery dates. A different appliance width can change cabinetry. A plumbing fixture can affect rough-in locations. A new window size can change framing.
Structural work, building systems, inspections, and finishes need to happen in the right sequence to avoid delays and rework.
Clear the work zone and decide how contractors will enter the property, where materials will be stored, and how demolition waste will leave the site. Protect floors and rooms that are staying intact.
Older homes require additional planning. EPA’s March 2026 lead-safe renovation guidance addresses work that can disturb lead-based paint in pre-1978 housing. Homeowners using contractors should also check whether EPA or state Renovation, Repair and Painting requirements apply to the project.
Suspected asbestos-containing materials deserve the same attention before disturbance. EPA explains that asbestos cannot reliably be identified by sight and recommends professional sampling when suspect material may be disturbed during remodeling.
Review its asbestos remodeling guidance before demolition in a home where older materials are present.
After demolition, resolve framing, foundations, beams, headers, roof changes, structural repairs, and new exterior openings. Additions should be made weather-resistant before vulnerable interior materials are installed.
Projects that change the footprint should be laid out against the approved site plan where one is required. Setbacks and other location requirements should be confirmed before permanent construction is committed.
Properties in regulated flood hazard areas need another check. Under FEMA’s National Flood Insurance Program framework, an improvement can qualify as a substantial improvement when the improvement cost equals or exceeds 50% of the building’s pre-improvement market value.
Local officials make the determination and apply the community’s rules. FEMA’s substantial improvement reference explains the calculation and compliance process.
Plumbing, electrical wiring, HVAC, ventilation, data cabling, and similar concealed systems should be coordinated before insulation and drywall.
Photograph open walls once rough work is complete. Photos can later help locate wiring, pipes, blocking, ducts, and structural components without opening finished surfaces.
Inspection timing varies by jurisdiction and project. Footings, foundations, framing, electrical work, plumbing, mechanical systems, insulation, and completed construction can each have separate inspection stages.
If an inspection is required, schedule it before concrete, insulation, drywall, or finishes hide the work. Keep the approved drawings available at the jobsite when your local authority requires them.
Structural work, building systems, inspections, and finishes need to happen in the right sequence to avoid delays and rework.
Once concealed work has passed required inspections, the project moves into drywall, cabinetry, tile, trim, paint, flooring, countertops, fixtures, lighting, appliances, and hardware.
The exact order changes by project. Protect completed surfaces from later trades and avoid installing expensive finishes before dusty or destructive work is finished.
Exterior renovations may also need drawings showing the finished appearance. Our elevation drawings can document elements such as roof form, windows, doors, building heights, and exterior materials when a permit office or HOA requests that information.
Walk through the project before final payment and record every incomplete, damaged, or incorrect item in one list.
Check:
Photos and room locations make corrections easier to track.
Confirm that required final inspections have been completed and that the local authority has closed the permit or issued the applicable completion document.
Keep one permanent renovation file containing:
A complete record gives future contractors better information and can be useful during later repairs, renovations, insurance questions, or a property sale.
Yes, many permits have expiration dates or become invalid if work does not start or remains suspended for too long. Check the rules on your specific permit.
It can. Additions and major improvements may trigger reassessment in some jurisdictions, while routine maintenance and repairs often do not.
For major renovations, yes. Improvements can increase replacement costs or change the coverage your property needs.
Often, but extensive demolition, utility shutdowns, hazardous-material work, or loss of the kitchen and bathrooms can make temporary accommodation more practical.
Ask the building department before making significant changes. A revised plan or permit amendment may be required before the new work proceeds.
Put every change in writing, including the added or reduced cost, revised scope, and effect on the project schedule.
Local rules vary. Confirm whether the homeowner or contractor must apply, and state permit responsibility clearly in the construction contract.
