What it is

You support small developers, landlords and investors on projects such as multifamily conversions, small commercial fit-outs and spec homes. Typical work includes feasibility and cost reviews, permit and code compliance checks, reviewing subcontractor bids, and monitoring budget and schedule.

Your first three steps

  1. Write a one-page summary of your experience and a few services you offer, such as cost review, permit check or draw inspection
  2. Contact local developers, real estate investor groups, architects and lenders to introduce yourself and offer a paid first review
  3. Set up an LLC, get an EIN, and get quotes for professional liability and general liability insurance
Who pays

Small real estate developers, investors, property owners and builders who need expert help without hiring a full-time project manager.

How it makes money

Monthly retainer, a fixed fee per project phase, or an hourly rate for specific reviews and reports.

Skills that help
  • Several years of construction, estimating or project management experience
  • Knowledge of local permitting and building codes
  • Cost estimating and scheduling
  • Clear report writing and client communication
Watch out for
  • Professional liability (errors and omissions) insurance, since commercial clients may ask for proof of cover
  • Check your state's licensing board: some advice, inspections or code work may require an engineer, architect or contractor license
  • Check whether you need a city or county business license, and whether home occupation rules or your HOA allow a home office
  • Large payments can be slow, so use written contracts with clear scope, deposits and payment terms
  • Work can depend on a few clients, so a slow property market may affect demand
