New Build Responsibilities: Owner, Designer, and Trades

A new build involves decisions that can fall between the owner, designer, engineer, contractor and trades. A simple responsibility map names who supplies information, checks selections and approves changes. Use it before work is treated as ready to price or build. Mark unassigned roles clearly instead of assuming another participant will cover them.
Home Addition Tie-Ins: Roof, Structure, and Utilities

An addition changes more than the home’s footprint. The new space must connect to the existing structure, roof, floors and utilities. Start with how people will move between the rooms, then review those connections with the design and construction team. Existing records and site review help establish what is known and what still needs investigation.
Occupied-Property Additions: Access Planning Questions

Building an addition while people remain in the home takes an access plan. Discuss entrances, deliveries, work-area separation and expected utility interruptions before assuming the household can stay throughout construction. This guide identifies what to record and which decisions belong in the proposed documents. Actual arrangements depend on the property and the work.
Detached ADU Lot Feasibility: Questions Before Design

Before designing a detached ADU, find out what the lot can support. Gather the survey, a rough placement sketch and what you know about access, drainage and utilities. For a Greater Houston property, the relevant jurisdiction and deed or HOA restrictions also need review. This checklist helps organize those questions without assuming the project is approved.
Detached ADU Use and Utilities: Layout Planning Guide

How an ADU will be used affects its layout and utility needs. Start with daily routines, privacy, access and the facilities occupants need. Then ask the appropriate professionals to review connections and capacity. Define those needs before fixing room sizes or appliance locations, and confirm permitted use separately from the design you prefer.
