How Much ADU Construction Owners Can Make: $145k To $23M

Measure Completion, Not Leads

Track the full path from inquiry to signed scope, permit, start, completion, and collection. The key test is completed and collected projects ÷ acquired customers. A strong inquiry count with weak completion burns CAC and traps cash in preconstruction.

• Track permit turnaround by job.
• Track starts, completions, collections.
• Flag funding gaps before mobilization.
• Forecast monthly completion capacity.

Use those dates to spot where revenue gets stuck. If permits or inspections slip, finished revenue moves right, and owner pay moves with it.

Track cash before owner draws

Track a rolling 13-week cash forecast, not just P&L profit. Watch cash on hand against the $607,000 reserve floor, plus payroll dates and capex timing. If the reserve is below target, hold owner draws and protect liquidity first.

• Cash balance versus $607,000
• Payroll due dates
• Capex payment timing
• Milestone collections
• Owner draws and reserves

If collections slip, the business can look profitable and still run short on cash. That is why the reserve target should sit ahead of owner pay, not after it.

Cut Stalls Before Permit

Track the funnel by stage, not just lead count: inquiry, signed scope, design complete, permit filed, permit approved, start, completion, and cash collected. One clean metric is the permit conversion rate from signed scope to approved permit, because that is where preconstruction cash gets trapped.

Set a cap on work-in-process before permit approval, then forecast preconstruction spend per active job. If that queue grows faster than starts, cash tightens even when sales look strong. The fix is simple: tighten scope documents, submit complete permit sets, and stop selling more preconstruction than the team can clear.

• Track stage-by-stage conversion rates.
• Monitor preconstruction cash per job.
• Compare CAC to collected revenue.
• Limit stalled jobs before permit.

Measure Every Cost Bucket

Build each estimate from the same buckets: materials, subcontractors, permits, commissions, contingency, and change orders. Then compare estimated vs. actual job cost on every completed ADU. If one line runs hot twice, raise price before you add more volume. That protects margin and keeps cash available for owner pay.

• Track estimate vs. actual by job line.
• Price change orders before work starts.
• Review cost overruns after each closeout.
• Forecast cash after permit and sub bills.

Keep margin high enough to cover payroll, overhead, and reserves. If a job looks profitable only before permits, subs, or change orders hit, the owner ends up funding the gap instead of taking home profit. Clean job costing turns revenue into real distributions.

Track Utilization Weekly

Measure projects per PM, designer queue, and subcontractor start dates every week. If headcount grows before completions do, you are buying idle payroll. Keep each FTE tied to a billed milestone, not bench time.

• Active jobs per project manager
• Design queue days
• Permit age and inspection dates
• Subcontractor commitment dates

Forecast cash by milestone, not just signed contract value. One late trade can block the next start, delay collection, and hit owner income twice: lower throughput and higher payroll drag.

Price The Mix, Not The Average

Track contract value by unit type, not by total pipeline. Build every estimate from hours × rate, then add scope items that change with size, like permits and sitework. If your two-bedroom share rises, forecast higher revenue and higher cash use together, or owner draws can get squeezed even when topline looks strong.

• Track studio, one-bedroom, two-bedroom mix.
• Reprice when hours or scope change.
• Watch permit and sitework cash timing.
• Separate quoted value from collected cash.
