What JKF Construction does
JKF Construction (JKF, Inc.) is a privately held custom home builder and remodeler founded in 1998 by Jeff Frankenfield and headquartered in Sunnyvale, California. The firm serves high-end residential homeowners across the San Francisco Bay Area, delivering two core service lines — full ground-up custom home construction and custom remodeling ranging from single-room additions to whole-house renovations, including historical Victorian restoration. Projects span from preliminary design consultation through building-permit submittal, construction, and final handoff, with a dedicated project manager assigned per engagement.
The firm operates without external capital, advertising, or a public sales motion. All new business is generated by word-of-mouth referrals and repeat engagements from a 25+ year client base, with the company explicitly stating it has never needed to advertise. The technology stack is light by tech-company standards — QuickBooks for financial management, Mac-platform tools (Numbers, Pages), and recently adopted LLMs and AI-related tools for operational efficiency. California contractor's license Nº 748930 governs its operations.
Pricing is quote-based and project-specific rather than standardized. JKF operates a two-checkpoint pricing structure: a budgetary check-in at preliminary design stage to align scope with budget, followed by a detailed final proposal once drawings are submitted for a building permit. Revenue is one-time project-based with no recurring subscription or maintenance stream. The current team is approximately 5 employees, including the founder, and the firm is actively recruiting an Assistant Project Manager & Estimator. There are no institutional investors, no parent company, and no ownership changes disclosed.
