New Single-family Housing Construction (Except For-Sale Builders)

NAICS 236115 · Construction of Buildings · SBA size standard: $45 million average annual receipts

Custom home builders who construct single-family residences on client-owned lots manage the full process from initial permitting and site work through framing, interior finishes and project closeout. Specialists turn owner selections into accurate material orders, convert architectural drawings into sequenced trade schedules with required inspections, coordinate licensed subcontractors, process change orders, and organize compliance and billing documentation. The builder and site supervisor retain all decisions on sequencing, quality approvals, payments and regulatory sign-offs.

What makes this business different

  • Custom architectural plans with extensive owner selections for structural options, finishes, fixtures, cabinets, appliances and mechanical systems that must be captured exactly before ordering
  • Municipal building permits, plan reviews and staged inspections (site, foundation, framing, insulation, mechanical, final) with jurisdiction-specific lead times and requirements
  • Sequencing multiple licensed trade contractors who must arrive in strict order on the same active jobsite without overlap conflicts
  • Material and equipment tracking for dispersed job sites including long-lead items such as trusses, windows, doors and mechanical equipment
  • Change orders that modify scope, cost, schedule and selections after construction begins
  • Progress billing tied to milestones, draw schedules, conditional and unconditional lien waivers, and retainage release
  • Site-specific safety plans, stormwater pollution prevention plans (SWPPP), erosion control measures and environmental documentation
  • Owner walkthroughs at key milestones that generate punch lists to be completed before final payment and certificate of occupancy

Workflows

Preconstruction planning and permitting

Starts when: Signed contract and initial deposit received

  1. Compile owner selections, architectural plans, engineering reports and site survey into a complete permit submission package
  2. Submit building permit applications and any required stormwater or environmental permits to the local jurisdiction
  3. Track plan review status, address requested revisions and schedule pre-construction meetings and utility locates
  4. Build the initial master construction schedule with trade sequencing, material lead times and inspection hold points
  5. Prepare bid packages for subcontractors and long-lead material suppliers

Watch for: Permit review durations vary by jurisdiction and can shift the entire project start date; Stormwater and environmental permits must be secured before any site disturbance

Site preparation and foundation work

Starts when: All permits issued and notice to proceed signed

  1. Verify utility locates, install temporary fencing, erosion control and stormwater best-management practices
  2. Schedule and coordinate clearing, excavation, footing, foundation and concrete subcontractors in sequence
  3. Generate and track daily safety and SWPPP inspection checklists with photo documentation
  4. Record as-built measurements and conditions before and after each major step
  5. Assemble and submit the foundation inspection package for building department review

Watch for: Soil test results and weather events may require last-minute engineering adjustments; Exact foundation dimensions and elevations must match approved engineered plans before concrete placement

Framing, roofing and exterior enclosure

Starts when: Foundation inspection passed and approved

  1. Release framing, truss delivery, roofing, siding and exterior trim trade packages in the correct sequence
  2. Coordinate delivery of lumber, windows, doors and sheathing to align with the build schedule
  3. Schedule rough-in trades (plumbing, electrical, HVAC, fire suppression) to follow framing completion
  4. Prepare and organize framing, energy and rough-in inspection documentation packages
  5. Track material quantities used and flag variances for potential change-order review

Watch for: Weather windows directly impact roofing, siding and exterior closure timelines; Long-lead custom windows and doors must be on site before interior work can begin

Interior finishes and mechanical completion

Starts when: Framing, energy and rough-in inspections passed

  1. Release interior trades (insulation, drywall, painting, trim, flooring, cabinetry, countertops) in logical order
  2. Match all owner-selected finishes, fixtures and appliances to purchase orders and delivery dates
  3. Schedule and document insulation, drywall, mechanical and final building inspections
  4. Compile punch-list items identified during owner walkthroughs
  5. Track completion status of each room or system against the master schedule

Watch for: Owner selections often change once they see the framed and roughed-in space; Multiple finish trades must coordinate within the confined interior of the home

Change order processing and integration

Starts when: Owner request or unforeseen site condition identified

  1. Document the proposed change with sketches, specifications or revised drawings
  2. Obtain pricing from affected subcontractors and material suppliers for the net difference
  3. Draft a formal change order document showing scope, cost, schedule impact and updated selections
  4. Update the master schedule, material orders and finish schedules after approval
  5. Log the signed change order in the project financial tracking

Watch for: Changes after framing can cascade through multiple downstream trades and inspection points; All changes must be fully priced, approved in writing and documented before any work proceeds

Progress billing and project closeout

Starts when: Milestone completion or month-end cutoff

  1. Generate schedule-of-values progress report based on verified completed work
  2. Collect and organize all subcontractor conditional and unconditional lien waivers
  3. Assemble draw request packages with supporting documentation for owner or lender approval
  4. Schedule final inspections and compile certificate-of-occupancy documentation
  5. Finalize punch list resolution, warranty binder and owner turnover package

Watch for: Retainage is withheld until all liens are cleared and final inspections are passed; Each jurisdiction requires specific closeout forms, as-built drawings and documentation

Subcontractor scheduling and verification

Starts when: Weekly and at every phase transition

  1. Confirm each trade's availability against the current master schedule and adjust as needed
  2. Send detailed scope-of-work packets, site rules, safety requirements and access instructions
  3. Verify current certificates of insurance, trade licenses and completed safety orientations
  4. Perform quality and safety checkpoints before releasing the site to the next trade
  5. Record completed work quantities and conditions for billing and verification

Watch for: Each trade contractor must hold appropriate licenses for the specific scope and jurisdiction; Insurance and bonding requirements vary by project size, value and lender standards
